2021 Chevrolet Suburban Complaint Log

The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle jerked abnormally while shifting into reverse(R) or drive(D). The contact stated that the vehicle lost motive power with the check engine warning light illuminated. The contact was able to restart the vehicle; however, the failure persisted while attempting to drive. The contact also stated that the vehicle was put into LIMP Mode several times. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 78,000.

Lane departure assist, adaptive cruise control, auto emergency braking, adaptive high beam, forward collision warning system became unresponsive while driving on highway during trip. Had to take vehicle into GM dealership for ADAS camera replacement.

Had an engine replacement in dec of 2025 and had to pay for it since wasn’t under warranty or recall. And now my replacement engine which has a warranty now. Just failed in March 2026 which about 3 months later. Had metal shavings in engine and multiple cylinders misfiring. And now I don’t have a family vehicle to drive my family around again. There should’ve been a recall on my engine, but wasn’t this is not fair. And I’m paying the price for it.

On Friday, March 13, 2026, while traveling at approximately 60 mph on the highway, my 2021 Chevrolet Suburban equipped with an L87 6.2L V8 engine experienced a sudden and complete loss of motive power. The failure sequence began with a dashboard warning prompting me to "press the start button again," followed immediately by the vehicle shifting into neutral without any driver input. Despite repeatedly pressing the accelerator, the vehicle continued to decelerate and could not re-engage drive. A second dashboard warning displaying "engine recall" then appeared mid-incident. Subsequently, the rear wheels locked, forcing the vehicle to coast to a complete stop on the hard shoulder without any brake input required from the driver. Upon coming to a full stop, the start button continued flashing with repeated prompts to press it, the vehicle lock emblem illuminated on the dashboard, and the vehicle became fully and mechanically immobile, unable to shift out of neutral or transition into any other gear. The engine could not power the vehicle at all. My safety and the safety of other motorists were directly and seriously endangered, as the failure occurred without warning in the middle lane of an active highway at highway speed, leaving the vehicle unable to maneuver or accelerate out of harm's way. A responding police officer confirmed the road hazard on scene and remained present to protect the vehicle and occupants while we awaited assistance. The AAA tow truck operator independently concurred upon arrival. The vehicle was transported to Classic Chevrolet, Grapevine, TX, the same day and is currently awaiting full technical inspection by the dealership's service team; an official mechanical diagnosis remains pending. The dealership service advisor has verbally confirmed awareness of an active engine and powertrain/transmission recall affecting this vehicle. The failed component — the L87 6.2L V8 engine and associated drivetrain — is available for inspection

My 2021 Chevrolet Suburban experienced a sudden and complete engine failure at approximately 79,000 miles. The vehicle became inoperable and is currently at a dealership pending evaluation. There were no prior warnings indicating an imminent catastrophic failure. A sudden engine failure of this nature presents a significant safety concern, including the risk of loss of propulsion during operation. The failure has been confirmed by the dealership, and no repairs have been authorized at this time pending further review. This complaint is being submitted to document a sudden and severe engine failure and to request evaluation of potential safety-related defects involving internal engine components.

In April of 2022 with 26k miles my vehicle had its first engine failure, Chevrolet dealership had to replace engine lifters due to a known engineering defect with the 2021 6.2 L87 engine. Now in late February 2026 with 80k miles my engine has locked up and requires a brand new engine replacement. For some reason, even though this is a L87 6.2L 2021 engine it is not part of the broader recall for this exact same engine failure for the same engine year and model.

The check engine and traction control light came on in my car. This was accompanied by a clanking sound, shaking. The panel said “ SERVICE ESC” “ service traction control” and “ forward collision system unavailable” The Chevrolet light logo on the back of my car will also not turn off occasionally whenever the car is turned off.

Engine failure at 86,000 miles with documented regular oil change and recommended services

My [XXX] Daughter lost the ability to put the vehicle in reverse while running errands on a Saturday. We had to push the truck out of the parking spot "backwards" in neutral in order to get the vehicle in a position to put it in "drive". She had been going in and out of shopping centers (forwards and backwards) earlier when the reverse suddenly stopped. I dropped the vehicle at a nearby auto shop in a fit of desperation (maybe 1/2 mile away). They told me they thought the transmission was shot, so I picked it up and took it to Andean Chevrolet (Dealer) in Cumming, GA. While driving it to Andean on Tuesday (2/17), the transmission went into low acceleration mode where I couldn't go into upper gears and topped-out at 3,500 rpm's max for the 13+ miles (30 min) drive. Andean confirmed on Friday (2/19) that the entire transmission is shot with metal all inside of the fluid, gears being broken, and the valve body being broken. The truck is 5.5 years old with 93K mile on it and we were just shocked. The repair for GM Reman transmission was quoted at ~$9.2K and we just finalized a call directly with GM Customer Service to see if GM would offer any discounts to the Dealer on the repairs. We are still waiting on that result while the repairs are being made. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Chevrolet Suburban. The contact stated that while in reverse (R), the vehicle failed to reverse as intended. The contact’s wife continued driving at approximately 55 MPH, and an unknown message was displayed, and the vehicle failed to exceed 55 MPH. Additionally, the transmission was stuck in gear and failed to upshift into the next gear as designed. The vehicle was pulled over to the side of the road, and the battery was disconnected and reconnected, but the message remained displayed. The vehicle was towed to an independent mechanic, where it was determined that the transmission control valve needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 81,600.

I am submitting this complaint to report a serious safety issue involving my 2021 Chevrolet Suburban equipped with the 3.0L Duramax diesel engine. The vehicle has experienced a recurring problem related to the engine wiring harness. While driving, the vehicle will unexpectedly stall without warning. At the same time, there is an immediate loss of power steering assist, significantly reducing the ability to safely control the vehicle. This creates a dangerous situation, especially at highway speeds or in traffic. The failure appears to be linked to a defect or malfunction in the engine wiring harness, which may be causing intermittent electrical interruptions to critical engine systems. There were no prior warning signs sufficient to prevent the incident. This issue poses a substantial safety risk not only to the driver and passengers but also to other motorists. Sudden engine shutdown combined with loss of steering assist increases the likelihood of a crash. I believe this may be a systemic defect affecting other vehicles of the same model and configuration. I urge the National Highway Traffic Safety Administration to investigate this issue and determine whether a recall should be issued. Vehicle Information: Make: Chevrolet Model: Suburban Year: 2021 Engine: 3.0L Duramax Diesel

See attached document for complaint.

While driving, the engine malfunctioned. There were no warning lamps, messages, or other symptoms prior to the malfunction. The vehicle has been inspected and repaired by a Chevrolet dealership.

My vehicle will not go in reverse.

While driving the Engine warning light, service ESC light, and collision light all came on and an engine knock started. I also experienced a loss of power at the same time. Car was taken to local Chevy dealership for evaluation and repair. Dealership advised that they dropped the oil and found metal shavings in the oil. After further investigation, we were advised that it was a crankshaft connecting rod failure. We have an extended warranty and were waiting to hear back on repair coverage. GM denied the repair as this vehicle is not part of the active recall. Our warranty company also denied the repair stating we did not have adequate records of oil changes. Receipts for oil and filters were provided.

My vehicle was taken in to shop due to recall recommendation I received in GM app for fuel pump control module . After repair was done my engine begin ticking the same day and failed a week later . I documented the whole thing and filed a claim with GM however the dealership that did the repair are not responding to GM . The dealership is alm Chevorlet south in Jonesboro ,GA this vehicle stalled out while I was on the highway . Please help me this vehicle belongs to my limo fleet and this is detrimental to my business . After multiple attempts to get it diagnosed they kept telling me I had to wait in line for weeks out to get it checked out although the problem arose after the new part installation . Then when I brung it back with failed engine soon after they told me that I had to sign a liability release waiver for them to check out the vehicle stating that the vehicle was high mileage and not their fault . The service manager literally instructed me not to leave my vehicle when I wanted to because it would not speed up the process for it to be seen I brung it back when instructed but it was to late because the engine had already failed . They literally forced me to sign a waiver stating that they wouldn’t diagnose it if i didn’t sign the waiver . These people are committing a fraudulent scam and their are unsafe vehicles on the road that arent being treated properly due to these practices . Please contact the dealership and or GM to take this matter more seriously .

The front of the fuel tank is hanging down and nearly dragging on the ground. This was with normal driving on a highway. No hitting bumps or aggressive off-road anything. We noticed when we heard a scraping noise going slowly over a slight incline in a driveway that it was hanging down.

On January 13, 2026, the engine in my Suburban failed suddenly and completely, rendering the vehicle inoperable without warning. The failure left me stranded with my children, creating a serious safety concern and requiring immediate towing. Prior to that day, the vehicle exhibited no ongoing symptoms, warning lights, or performance issues, aside from a ticking noise that appeared only on the day of failure. The vehicle was towed to an authorized Chevrolet dealership, where it was determined that the engine was damaged beyond repair and required full replacement. I was informed a new engine would need to be ordered, at an estimated cost of approximately $14,000—an extraordinary and unreasonable expense for a vehicle of this age and price point.

The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving at various speeds, the steering wheel was difficult to turn to the left or the right. The contact stated that the failure was intermittent, but was a recurring failure. There was no warning light illuminated. The contact stated that prior to the failure, there was an abnormal whining sound while turning the steering wheel. The vehicle was not taken to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 33,000.

The contact owns a 2021 Chevrolet Suburban. The contact stated that while driving at various speeds, an abnormal oil consumption was noticed. No warning light was illuminated. In addition, the vehicle was previously taken to a local dealer, where an oil consumption test was performed; however, the contact was advised to bring the vehicle back for further investigation. An appointment with the same local dealer was scheduled to inspect the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 60,000.

My vehicle is having an oil consumption problem. 2 quarts were missing from my oils consumption test. The dealer is now doing a secondary oil consumption test and I’ve read up and learned that there have been a lot of recalls with the engine and oils changes.

There is an electronic problem that continues to trip the warning for the Air Ride suspension system to fail leaving the vehicle stuck at its current ride height or it drops eithee the front or rear suspension to the ground while simultaneously raising the front or rear to its highest setting. It also causes the vehicle speed to drop immediately to 56 mph. Issue has been scanned by several dealers to determine air leaks, pinched wires, failing compressor and all were found to be in normal operation. This is a huge safety concern as well as a huge financial concern for the consumer.

Rear Axle is grinding. Took vehicle into dealer and it is the well documented rear axle issue but this vehicle is not included in a recall. The differential fluid was replaced and figure 8s were done but there is still grinding. The rear axle also drags at times when in auto 4wd. The dealer said the next step would be to replace the axle. This is the issue: Differential Noise/Failure: Reports indicate a rubbing noise while turning, often attributed to the rear differential. In some cases, the entire rear differential has required replacement.

The car was driving at 60 MPH on a regular commute to work and the car was stalling and shaking and soon after the check engine light came on with multiple issues.

I have a 2021 Chevy Suburban with the L87 6.2L V8 engine. At 7k miles, we have lost propulsion, leaving the car undrivable. resulted in the dealer replacing all 16 lifters under a recognized bulletin. I never received extended 6yr 100k mile powertrain warranty as described in the bulletin. Since then, There have been 3 other issues with loss of propulsion, resulting in replacement of fuel pump modulator. belt pulley system, One of the incidents left us without power or control of our vehicle on the interstate, with no where to pull over or get out of the way of oncoming semi trucks. The last incident again left the vehicle undriveable at 84k miles, with the dealer currently reporting that it is a lifter and cam shaft issue. Resulting in a 10k bill. They state that it is not covered under the recall of these engines because it is the top of the engine versus the bottom. Clearly, the engine oil problem noted in the recall has contributed to these issues . and the crankshaft not syncing properly with the lifters.

Went into limp mode on 11/6/25, took to the dealership where they found metal shavings in the oil due to a “stuck solenoid ‘A’”. Originally said that I’d need a whole new transmission, decided to do the cheaper easier repair and just replaced the valve train (not my choice) got it back on 11/13/25. On 11/24/25 I was on a very busy highway, at a red light, hit the gas when the light changed and the car didn’t move. Just revved the RPMs, then it suddenly lurched/surged forwards. Took it back to the dealership and they said “it doesn’t have any codes showing”. This is not normal behavior for a 4 year old vehicle with less than 40k miles on it.

The vehicle caught on fire in our garage The Vehicle had been parked outside than moved into the garage nothing smelled like smoke after it was parked other than the exhaust after I got out of my suburban I have a good idea what caused this but until its done being ispected I happened to look back and saw a flame in the Suburban coming from the center area of the dash on the right hand side of the divers seat I thought for sure it was gonna blow up the dogs were in the back of the garage behind the vehicle off to the side I started screaming and calling for help and had to go around the house to the front door to get my husband and him and one of my sons went out there why I called 911 and was with my other son whom has a disability and they told us to get out of the house and I could not get back to the garage we were on the other side of the house going to go out on the patio my other son and husband were in the garage trying to put it out and getting to the two dogs my son went through the smoke to reach the dogs were one ran out on her own and the young German shorthair was in shock and he had to carry the 2 year old out and put them in a safe place but my husband was still trying to put out the fire he hooked his pick up to the suburban to try to pull it out of the garage and it moved maybe a few inches he was stuffing wet towels on it also to try to stop it nothing worked the fire dept showed up and police after having to tear the inside of the front of the dash out our home owners insurance adjuster was out yesterday The Suburban has had multiple and thousands of dollars of mechanical issues even Gm putting a new engine in it after only a year in a half of owning it fluid got pushed up into the wiring after a service last year there was splater inside the dash glass after a new steering wheel was istalled and I asked the dealer if they could fix that and they said that they didn't go inside there the amount of detail that has led up to this is huge

Vehicle experienced sudden engine malfunction including rough idle, hard misfire, and flashing check engine light. Vehicle was diagnosed with a collapsed lifter and internal engine failure. Metallic debris was found in the engine oil, including silver and gold/bronze particles consistent with bearing material. A Chevrolet dealer inspected the vehicle and determined that the engine requires complete replacement due to internal mechanical failure. Vehicle is equipped with the 6.2L V8 (L87) engine. The failure occurred without warning and presents a safety concern due to potential loss of propulsion. This vehicle is not currently included in the existing GM 6.2L engine recall, despite exhibiting the same failure characteristics reported in other affected vehicles with the same engine and year that were included in the recall. Vehicle has not been driven since metal contamination was discovered to prevent further damage

We have a defective engine that stopped working after 120 miles. We can drive the car because it can leave us on the road or catch fire, this is what the mechanic told us, GMC option is to buy another car.

Engine is shaking like a bearing is going out, I've seen multiple recalls on this engine but for some reason my 6.2 isnt apart of them.

I was driving and then the vehicle started running rough. There was no indication or warning lights before this happened. This is a huge safety issue because I could have had a wreck and injured people and my very own family. I took it to a Chevy dealership. They inspected the suburban and number 4 cylinder had a pool of oil in it. And they told me it need a new engine. Which it has the L87 engine that all the GM recalls are on. However, they are telling me mine isn't on the recall. They don't know if GM is going to cover it because it has 111,000 miles and it's out of the power train. It's the same engine they're having trouble with engines failures on. And I believe mine should be under the recall.

See attached document for complaint. To Whom It May Concern, I am writing regarding the recall on my 2021 Chevy Suburban. While I understand there is currently no active solution for the issue, I want to stress the seriousness of the situation. As a mother of [REDACTED] living in Wisconsin, I am deeply concerned that if my truck were to shut down due to engine failure and we could not get help quickly, my family would be exposed to the risks from the fire that inevitably could arrive. Given the harsh winters there, this poses an unacceptable safety risk. Additionally, I paid for an extended warranty, believing I had plenty of coverage left. I recently brought my vehicle in only to be told that I was 500 miles past the 60,000-mile limit, I was under the impression the warranty had not expired, and if I had known otherwise, I would have brought it in much sooner. This issue has been ongoing for at least 6 months, and I have been aware of the mileage restriction, I would have scheduled service well before this point. On top of that, my Suburban continues to emit the smell of burnt oil. It is embarrassing to have my vehicle smell like it's burning every time I drive it, and it raises serious concerns about my health. Breathing in burnt oil fumes regularly cannot be good for my lungs or overall well-being. This issue has also created a financial burden for me, as I am currently trying to sell the vehicle. In its present condition—with the burning oil smell and unresolved recall—it is essentially unsellable. No buyer wants to take on these risks and uncertainties, leaving me stuck with a vehicle I can neither comfortably drive nor reasonably sell. This matter is not just about inconvenience. It is about safety, that matters, and other concerns, trust and accountability. Chevrolet has marketed its vehicles as reliable, family-safe transportation, and I want to feel assured that GM takes immediate action to properly address this oil consumption and/or issue. Anything less is unacceptable when it comes to the safety of families who trust your brand. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine while driving completely seized up. Crank shaft, cam shaft and oil pump water pump replaced. Low oil pressure alarm code present then sudden loss of power. Piston blown. There are similar recalls to 2021 suburbans however, this specific model is not in the recall. I was told I need a completely new engine. The car died in the middle of traffic and police had to call an emergency tow truck.

My 2021 Chevrolet Suburban stalled while driving in late September 2025 and had to be towed to a dealership. The vehicle is subject to an active fuel pump power control module safety recall that has been in effect since 2021. The vehicle was brought in specifically for repair of this issue. The work was processed under warranty, and I was charged a deductible. After learning the repair was directly related to an active safety recall, I requested reimbursement of the deductible, as recall repairs should be completed at no cost. That reimbursement request was denied. I have since been informed that the recall repair was never “completed,” and the recall still shows open in the manufacturer’s system. I am now experiencing shuddering and symptoms consistent with a potential stall recurrence. The original stall occurred while I was transporting my children, including special needs children who require regular transportation to school and therapies. The vehicle failure left us stranded at night in an unsafe area. Due to the prior stall, the unresolved recall status, and the recurrence of symptoms, I do not feel the vehicle is safe to operate. Thank you for your attention to this matter, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving along on a city street, the check engine light came on. Once I turned onto the highway, there was a pop from the engine, and the vehicle started missing and vibrating. I turned around and drove the vehicle back home. A mechanic looked at it and said there were a lot of problems and recalls on these vehicles for misfiring. He said the problem is the lifters and they need to be replaced as soon as possible. He encouraged me not to drive it due to it may cause more damage.

Engine light comes on and now flashes. The service traction control and esc comes on. The whole vehicle shakes when idling. Certified GM dealer hooked it up and it says misfiring cylinder 6. All spark plugs replaced, new GM coil, new spark plug wires. Nothing has fixed it yet.

I was driving when I received messages saying service ESC, Forward collision System Unavailable, & Service Traction Control. The vehicle began to shake hard when I applied brakes, had loss of power when pressing the gas pedal, and sounded like metal grinding. All of this put my children & I at risk as we were on interstate 35 with cars flying past us and I’m losing power. Initially the spark plugs and coil was were changed to no repair. It was towed to a dealership where they confirmed the lifter & cam failed which put metal in the oil. My only option is a full engine replacement costing 20k on a vehicle that’s 4yrs old. It’s not ok that I have to spend that in order to get my 70k car drivable. Im now without a car, still paying a car note, unable to get my kids places, and having to get help from friends all bc GM can’t build a quality vehicle. I also haven’t been able to get a loaner car. This isn’t happening in only the 6.3L. This is a widely known issue with the 5.3L as well. *There were ZERO warning signs that something was wrong. Drive just fine that morning*

I was standing at a red light with my foot on the brake and the car went into neutral and stalled. I could not restart the vehicle and had to be towed to the dealership where there confirmed a fuel pump module failure. There were no precipitating factors or warnings. This is extremely dangerous. The car is only 4 years old and many people have reported the same incident online, which often recurs, even after replacing the fuel pump. The dealership has ordered the part however it is on backorder without any estimated ship time. For a vehicle I paid over $70K for, this is concerning and frustrating. There is a known recall for 2021 Suburbans for this exact issue.

Driving vehicle on a highway at 55mph, tried to speed up, no propulsion. Fuel injector went bad.

My suburban is 4 years old and needs a new engine. The dealership is seeing a lot of 21's with the same issue. Bank 1 and 2 have failed, both powerods are broken and the cans and lifters have failed. There were no prior warning. We were driving and 2 warnings popped up and we took it to a dealership. We then went to a private repair shop for second opinion. The warranty is 70k miles and my car is 72k miles. This should not be happening with a 4 year old. The other Suburban engine has been recalled but mine has no current recalls on it.

My 2021 Chevrolet Suburban experienced a sudden no start condition which required the vehicle to be towed for repair. A diagnostic inspection determined that both the fuel pump and the fuel pump control module had failed. I paid out of pocket for the full repair, including replacement of both components. Several months later, GM issued a safety recall for the fuel pump control module on this vehicle. I submitted a reimbursement request to GM. GM agreed to reimburse only the control module , but refused to reimburse the fuel pump, even though the pump failure was directly caused by the defective module that is now under recall. Federal recall reimbursement guidelines require manufacturers to reimburse the full cost of the remedy for the defect. In this case, the defective module caused the fuel pump to fail, making the pump replacement part of the necessary remedy. GM’s refusal to reimburse the full repair cost leaves me paying for damage caused by the recalled component. I am requesting NHTSA’s assistance in reviewing GM’s refusal to reimburse the full repair cost associated with this recall related failure.

Was driving about 45 mph on 2 lane road. All of a sudden, without warning we lost power (had no propulsion). Luckily there was a residential side street that we were able to turn onto and get off of the highway with no shoulder. We coasted to the side of the street and called a tow truck. Had we not been able to get off the road, we would have been dead in the road, blocking an entire lane of a busy 2 lane highway without a shoulder to pull off on. There was no warning prior to incident but a message did appear during the incident. I believe it said "Loss of propulsion." We turned off the vehicle, then tried to restart it. Engine attempted to restart, but it made a horrible noise & wouldn't restart. Still had battery power. Vehicle was towed to a local dealership where it is currently being evaluated. We know of a massive recall on the 6.2 l engines. Ours is a 5.3 l engine. So far I'm seeing many people having problems but no official recall for the 5.3 l engines that are having THE SAME issue as the massively recalled 6.2 engines. This needs to be looked at. Our Vehicle only had less than 30k miles on it. We bought it new and have done routine maintenance.

On 7/26/2025 approximately 8:30pm (PDT), driving south on CA I-880 in third lane from right traveling at approximately 50mph when vehicle engine died and went into neutral gear. Dashboard alert indicated to press start engine button, but would not start. Managed to maneuver vehicle to right shoulder amid rush hour traffic. Fortunately, a CA Highway Patrol officer saw us and was able to render assistance. Vehicle would not restart or go into neutral after several attempts to restart engine. Special tow vehicle was called to give us a tow home. This incident happened after we received a Chevrolet recall notice back in May or June about the engine and did take the vehicle in for service on 6/10/2025. The dealership service recommended using higher weight oil and it would help mitigate any potential issue. Obviously, this was not the case. We were very fortunate to avoid any serious injury or damage on the highway due to engine failure.

After a major HVAC repair involving the evaporator core (performed at a Chevrolet dealership), my vehicle began experiencing serious electrical issues. The second-row 12V outlet no longer functions, and the vehicle has gone completely dead three times while the engine was off due to the auto stop/start system — once while stationary on a major highway, creating a dangerous situation. Each time, the engine failed to restart automatically, and the entire electrical system became unresponsive.

My wife was driving the vehicle and was pulling into a parking lot. The brakes failed and would not stop the vehicle. She pressed on the brakes very hard, multiple times, for several seconds, before the vehicle finally came to stop. She then proceeded into a parking spot where the brakes again failed to stop the vehicle promptly. Several lights illuminated and a “System Brake Failure 43 MPH Top Speed” message appeared, alternating with several other messages appearing. The vehicle is in for service at Classic Chevrolet in Granbury, Texas. They are telling me that they reset the codes and that the codes are not returning. I am extremely concerned that if I pick up the vehicle at this point, the brakes could fail again and cause an accident with serious injury.

The contact owns a 2021 Chevrolet Suburban. The contact stated that the check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where the map sensor was replaced; however, the failure persisted. Additionally, the vehicle failed to start. The vehicle was towed to another mechanic, where it was diagnosed and determined that the fuel pump sensor module had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 62,000.

What component or system failed or malfunctioned, and is it available for inspection upon request? Fuel pump How was your safety or the safety of others put at risk? Yes, vehicle stopped unexpectedly and and wasn’t accelerating Has the problem been reproduced or confirmed by a dealer or independent service center?no Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?

The contact owns a 2021 Chevrolet Suburban. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that while driving at various speeds, an abnormal sound was coming from underneath the hood. The check engine warning light was illuminated. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

What component or system failed or malfunctioned, and is it available for inspection upon request? -My engine started to make a loud ticking and knocking noise. I brought it into Good Chevrolet in Renton WA 6/3/25 where they told me there is an “internal engine failure due to failure of the lifters.” When I asked the dealership for the repair estimate so I could possibly have a second opinion, they said they were “not comfortable giving their information and the problem in writing.” They refuse to give us any documentation but were insistent that even though NHTSA has issued a mass recall for this exact same issue on the larger engine in my same year of vehicle, “it’s unrelated.” How was your safety or the safety of others put at risk? -The engine is failing and had we not brought it in for diagnosis, I could have had full engine failure while driving with my children and been in a catastrophic crash. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes the problem can be reproduced and has been confirmed by Good Chevrolet. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -Good Chevrolet inspected the engine but refuse to give us documentation though they had us file a claim with GM (I will attach the claim email) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -I noticed a small noise after I had fans replaced in September but the noise gradually increased so it was brought in for diagnostics. There were no warning lamps or messages.

Engine is skipping when in reverse.
