Fuel line has a hole in it from rubbing against the frame this is the 2nd time I've had to repair the fuel line in the 3.5 years I've had the vehicle

While driving on the highway I notice the rpm’s were high and the vehicle wasn’t going anywhere so I had to pull over from the middle lane to the side of the road I. Busy traffic gladly I mad it over safely without getting hit. After I pulled over the service engine light come on and the transmission temperature was high. After the vehicle cooled down and I was able to me the shifting was terrible it would jerk while shifting. So I called aamco transmission and they said I needed a transmission replacement. This is not the first Chevrolet Tahoe I have had that done this my 2010 Chevrolet Tahoe done the same thing and needed a transmission. The repair cost is at $5500.00.

The "Service Trailer Brake System" pops up on the dash and makes noise every 45 seconds. Its distracting and dangerous to be driving while this is happening.

All driver assist functions failing

I was constantly smelling a strong odor of gas coming from the inside/outside of my 2015 Chevy Tahoe. When I purchased the vehicle in 10/23 everything appeared fine. I researched the internet to determine what the problem could be & found dozens of similar situations. People saying the fuel line rubs the undercarriage of the vehicle causing a pin hole size in the fuel line causing it to leak gas. Currently my vehicle is in the shop and the problem is TBD.

On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "Service Trailer Brake System" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other GM vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.

While driving the breaks failed to work. Then when I started pumping the brakes again it took longer than normal to respond and I had to press really hard. I was only going a few miles per hour in a parking lot. Now 5 days later it's happening all the time. It's also making a click noise when I press the pedal.

The high pressure fuel line from the fuel pump to engine sustained a pinhole leak over the fuel tank. Fuel leaked over top of tank and ran down front drivers side front of tank. Discovered the leak after noticing strong fuel odor inside vehicle. Took to shop. The fuel line is installed as so it will rub undercarriage of vehicle. This is what happened to mine. This is a factory install and the lines are doomed to fail because of this. The excessive contact rubs holes into the lines. This seems to be a common problem with the 2015, according to my research. There are hundreds of these same complaints with this year listed all over repair sites on the internet. I believe this needs looked into, as flammable fuel leaking suddenly can be a hazard.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that she would smell the odor of gasoline when she approached the vehicle. The contact stated there was a stain on her driveway that was gasoline. Most recently, the contact saw that fuel was dripping from the fuel tank. Also, the contact stated that the vehicle had become more difficult to start in the morning, sometimes taking over four attempts. No warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer had been informed of the failure. The contact had researched online and related the failure to the manufacturer Technical Service Bulletin Number: 17-NA-304 Possible Fuel Leak (Fuel System, Gasoline). The failure mileage was approximately 120,000.

So I got a 2015 Chevy Tahoe that had recalls done but the problems are still there. The power steering works like every 10th time starting the suv.

Gas leaking out of my vehicle. First noticed it right after pumping gas then started smelling a strong odor of gasoline!

The contact owns a 2015 Chevrolet Tahoe. The contact stated that after refueling the vehicle, an abnormally strong fuel odor was detected. The following day, while starting the vehicle, the strong fuel odor was detected again. Additionally, the contact noticed fuel leaking from the fuel line onto the ground when the vehicle was parked. The vehicle was taken to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 182,000.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving at a slow speed and while making a left turn into traffic, the power steering assist malfunctioned and the steering wheel became difficult to turn, causing the vehicle to erroneously drive into a busy intersection. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 108,000.

I have not had a wreck but the fact that when you press the brake pedal the dome lights blink and when you turn on the left turn signal, the dome lights blink. If you hold down the brake like if you’re at a traffic light the dome lights blink continuously until you let off the brake. Now, during the day, that’s no big problem but at night it poses a serious safety risk. A bright light in your eyes while driving is blinding and a sudden bright light in the pitch black dark could lead to an accident. I called the dealer to ask about it and was told yeah, they knew about it and it would cost me like $550 to repair even though it was a defect that they readily acknowledge.

While driving I periodically receive a notification on the dash to "Service Trailer Brake System". The message just randomly comes up with an abrupt warning noise which is a distraction and startles you until it goes away. I don't tow anything with the vehicle. The notification happens about once a month when driving and eventually goes away after a few minutes. I do mostly interstate driving and when the warning comes up, it startles you and you feel the need to pull over immediately. The notification noise is loud and a distraction. I will be taking it to a Chevrolet dealership. I have an appointment late August. This has been going on periodically for months.

The fuel tank is leaking from the top of the tank.

In approximately December of 2015, we purchased a 2015 Chevy Tahoe LT from CARR Chevrolet. We chose GM for the reputation, under the belief if we took care of our vehicle and had it maintained by the dealer, it would last 12-15 years. This was NOT our experience.Three years after we purchased the vehicle, the engine died. We were assured this was an anomaly and GM replaced at "no cost", as it was a "manufacturing error". CARR service convinced me it was “great”, as now my vehicle would last even longer. I did not question and blindly trusted those I viewed as trained, skilled professionals. Fast forward to present time, my vehicle is 7 years old (90,000 mi) and never missed a single service. Out of the blue, the transmission dies. I was initially told this is “normal" and “happens” to a tune of $8400 plus maintenance and other wear and tear for a total of $10,000+. This did not sit well with me and I questioned the validity. I requested that CARR give me a quote to buy back the car and they initially refused to give decent price. I contacted GM to complain. After many more days, I was contacted and offered that GM and CARR would carry 70% of the cost of the transmission. I agreed with intent to sell/trade on my own. After many weeks, I picked up my Tahoe and paid $3,400 and headed back to Lake Oswego. As I entered downtown Lake Oswego on a slight hill, coming to a 4 way stop, my brakes completely failed…. I barely missed careening into the back of a car, as they naturally moved forward. I contacted CARR service supervisor, sobbing and shaking after the events and he immediately arranged for a tow. I then contacted the investigator. After many days, the GM investigator response, “it’s fixed free of charge”. I was told it was “known” that these cars “could” have a problem with the brakes, which is why there was an unlimited warranty should it occur. I expressed that I had zero trust in GM, CARR or the vehicle and expected to be compensated. The contact stated her understanding was that the GM recall related to brakes in 2019; only consisted of replacing computer chip and they knew that this was not the complete fix. They then issued an “unlimited warranty” on the brakes for people like me.

The torque converters for the 2015 Chevy Tahoe’s or the 6L80 transmission are failing at a rate not seem on a newer vehicle. Chevy dealerships in my area are backed up for 2 to 3 weeks just to look at the possible problem. The failure appears to be due to poor design of the transmission torque converters. Safety is at risk due high failure rate that could occur at highway speeds and thus making the vehicle stop without brake lights and possible fail in the middle of the highway. At highway speeds this failure could cause serious damage and possible death. Due to the 2 to 3 weeks for the transmission to be looked at by Chevy, I chose to take my vehicle to a private repair shop. Prior taking my vehicle to the shop the shop knew based on the high failure rate that my transmission failure was based on the torque converter but the total damage was not known until the transmission was rebuilt. The transmission torque converter problem was reproduced and confirmed by an independent service center. The Transmission was inspected by AAAA transmission located in Fort Worth. The only warning I had of the failure of the transmission torque converter was accelerating to access the highway and the vehicle started to lose power and shutter due to the lack of acceleration. The luck for me was the highway was not crowded and I did not merge on the highway with the loss of power and possibly getting hit from behind by another vehicle. There were no warning signs of the failure the vehicle just started showing signs of the failure that day. The failure first appeared on June 30, 2023. Attached is the copy of the repair bill and pictures of the metal shavings due to the failure of the torque converter which destroyed the transmission pump. The shavings are steel and aluminum particles.

Transmission issue 2015 Tahoe: When accelerating when entering freeway to merge, or similar, vehicle sometimes experiences a sudden loss of power and lurch sensation -- almost feels like the truck was hit. Speed doesn't increase when needed in crash avoidance maneuver or when accelerating during general driving. Eventually transmission failed. Rebuilt. Has the same issue now. Appears this is part of GM class action lawsuit for transmissions and torque converter issues. Very disappointing.

Leaking fuel from the in-line on top of gas tank. Very dangerous and alarming that this is a known issue and you choose to set back doing nothing. It’s the same exact problem that everyone is talking about so it’s be nice to be reimbursed for the parts or repair or something

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while her husband was attempting to secure the seat belt, the metal cable bolted to the driver's side seat snapped in half. The contact stated that the lap belt was loose. The contact stated that the lap belt was buckled but the driver was not secured in the seat. The contact stated no warning light was illuminated. The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 90,000.

There’s a recall for this exact issue, but my vin doesn’t fall under it. But the issue is the brakes suddenly felt different while they maneuvering into a parking spot or slowing for a pedestrian. Happens a lot at very low speeds.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that upon making a turn at slow speeds, the vehicle inadvertently shut off. The contact stated that an unknown warning light flickered on the instrument panel. The contact also stated that the vehicle restarted soon after failure. The contact attempted the notify the dealer of the failure but was informed to call back. The manufacturer was made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 100,000.

While driving at any speed the transmission felt like it was shifting gears into neutral on its own and the transmission has since failed. The vehicle is available for inspection. The vehicle dropped drastically in speed in a higher speed zone which could have caused an accident. The problem has been confirmed at the dealer with an inspection. The vehicle has been inspected by the dealership. There were no warning lights until the failure occurred and there were symptoms 2 weeks before the failure.

I own this 2015 Tahoe, it has 80,000 miles on it. While I was driving to work, the vehicle lost power as I was in the middle of major intersection. I was almost rear ended by another car. A few seconds later the car began going again. I had no service lights, no warning lights and no check engine light come on. It was running rough, lacking acceleration. I immediately brought it to my mechanic. They did they're testing and found Cylinder# 6 has collapsed. I was told that I will need a new engine at costs of over $8000.00. I have always maintained my vehicle and it's had regular oil changes every 4000 miles. In fact I'm still making car payments, and now I have to absorb this major cost of replacing an engine. When I looked on line to find some information of this Lifter problem, I found thousands of complaints of premature engine failures on these very expensive vehicles. I believe GM or Chevrolet needs to have a solution to this. How can they expect us consumers to afford this costly repair on such low mileage vehicles. Please look into this Manufacturers problem

The car was bucking on the highway it was losing power without notice. There was no prior notice from Onstar system either of any mechanical issues . There was No prior indications or check engine light before this instance. I was coming home in the dark on the highway which was a dangerous position to be in. The car's transmission Failed out of no where! I have had the car 22 months and was purchased from the Chevrolet Dealer.

The contact owns a 2015 Chevrolet Tahoe. The contact stated while driving at an undisclosed speed, the vehicle started to sputter and misfire before returning to normal functionality.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving at undisclosed speeds, the electrical system was failing intermittently. Additionally, several unknown warning lights were illuminated. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 122,000.

This 2015 Chevy Tahoe stopped without warning or warning failure indicators and continue to stop without warning, while driving on highway. Managed to drive the car slowly home. Following day the engine warning light came on after the fact. Had the car inspected by mechanic who indicated that the transmission/torque converter had failed. This mechanic has reported seeing the same issue with other Chevy Tahoes in same and similar years. Chevy has not addressed the safety hazard this transmission poses to both the driver and drivers behind the vehicle when it abruptly comes to a stop on a busy road. The car was just serviced at dealer in past month without any recommended repairs. The engine warning indicator did not work the entire time the car was whistling, stopping and jerking. Chevy should have issued a recall for this failure.

Transmission had to replaced 2/2023 with 140,810 miles.

My 2015 Chevrolet Tahoe with 90,000 miles needs a new camshaft and all 16 lifters need to be replaced. There was no forewarning about this huge problem. Literally, one day I was out in my car, and the accelerator suddenly stopped working for a while. Then, all of a sudden there was a hard jerk, and it sped up on its own. When I finally found a safe spot to pull over I went to push on the brakes and the entire car just started shaking. My poor children were terrified as this could’ve turned into a terrible accident for me and the other drivers around me. I immediately called my local mechanic and was told to bring it in immediately. On my way there the service indicator lamp came on. Upon inspection by my mechanic I was told I need a whole new engine. I have not had it repaired because I cannot afford to do so. I would be more than happy to allow someone to come and inspect it upon request. Apparently this is a huge problem with GM vehicles that GM is completely choosing to ignore.

Check engine light came on after vehicle starting losing power in steering column. Speedometer was moving up and down with some other gauges doing the same simultaneously. The vehicle provided warning of stabilitrak after dismissed, it gave another warning stating, “Steering Assist is Reduced Drive with Care.” It became harder to accelerate and very distracting as the stabilitrak error continued to pop up with the speedometer and other gauges, such as RPM, going up and down continuously. These gauges would then stop working altogether then start to work briefly. Then, the gauges would continue to malfunction by going up and down with the stabilitrak error on screen. I got off the interstate and I have having issues with acceleration from first gear. Vehicle was hesitating which was terrifying. It was failing to engage. Transmission fluid rose from 187 to 208 degrees during a brief time period on the screen. Could not use the M gear at all.

The car started shuttering and a burning smell occurred. Car was stuck in 1st gear and had had to be turned off in the middle of the road and turned back on. Was able to bring it to a repair shop where they had to remove and repair the transmission before it was Driveable

2015chevy Tahoe LT fuel pump rattle cause fuel line to rattle. Service Bulletin Bulletin No.: 17-NA-304 Date: February, 2020 Subject: Brand: Cadillac Chevrolet TECHNICAL Ticking, Rattle and/or Buzzing Noise Heard from inside Passenger Compartment, Possible Fuel Leak Model: Escalade Escalade ESV Model Year: from VIN: Engine: L86 L86 L83 L83 L83, L86 L83, L86 Transmission: to from to Suburban Tahoe 2015 Yukon Models Yukon XL Models 2020 GMC Involved Region or Country North America, Middle East, Europe, Russia, Chile, Columbia, Ecuador and Peru. Condition 1 Some customers may comment on the following condition: • Arattlingand/ortickingnoisethatmaybelouderinsidethevehiclethanoutside. ⇒ The noise may be picked up at the back of the left valve cover, and/or underneath the vehicle near middle of the driver’s door. ⇒ This noise will be noticeable at idle, most noticeable in the 700-900 RPM range. ⇒ The noise may also sound like a lifter tick. ⇒ This may also be called a fuel line buzz or ringing noise. • Whiletherattleisoccurring,theS-shapeportionofthefuelfeedline,rightinfrontof the tank, will be vibrating / rattling. Condition 2 Some customers may comment on a fuel leak. Diagnosis that the fuel leak is originating from the fuel feed line at the molded-in clip on top of tank. Cause The rattling, ticking noise may be caused by the check valve in the low pressure fuel feed jumper line at the engine not fully seating, allowing pressure pulses from the high pressure side back into the low pressure side of the fuel system. These pressure pulses could cause the S-shaped portion of the fuel feed line, in front of the tank, to vibrate and/or rattle If the S-shaped portion of the fuel line rattles over a period of time, the fore-aft motion in the line could result in wear. This wear could result in a fuel leak where the line is secured into the molded-in clip on the tank.

Car died with no dash warning. Had battery and alternator checked, battery checked out perfectly fine but alternator needed replacing. Replaced brand new alternator. After replacing, message came up “power steering drive with care”. Steering went completely hard, no other messages or absolutely any lights on dash. Unable to drive due to car steering wheel being locked. The contact has stated that the dealership confirmed the recall and that this issue is common, yet they have not found anything wrong with the vehicle.

The truck vibrates violently when truck I accelerate and feel like I'm losing control of the truck. The transmission is said to have issues with the hydraulic system.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that the front driver’s side seat belt tensioner cable failed. No warning light was illuminated. The vehicle was not diagnosed or repaired. The contact referenced NHTSA Campaign Number: 21V450000 (Seat Belts). The dealer and the manufacturer were notified of the failure and the contact was informed that the VIN was not included in the recall. The failure mileage was approximately 96,000.

The fuel feed hose that tracked on top of the gas tank rubs against a portion of the tank and a pinhole sized hole gets created. Anytime the vehicle is on or fuel pump pressurizes the line, fuel is sprayed all beneath the vehicle. Gm has made a “fix” to the line by adding a shroud to the updated part. Part number 84200271 is the updated part. I contacted Martin Chevrolet in crystal lake Illinois and was advised since my vehicle was out of warranty nothing was covered. Spraying fuel due to bad engeeniering is as unsafe as it gets.

Vacuum pump related to the braking system is failing. This has been a repaired recall. The Vac umm pump is failing again. It is my understanding this is a common issue with Chevrolet and GMC and is causing accidents.

WHILE DRIVING HOME FROM CORNER STORE, POWER STEERING LOCKED UP WITH VERY LITTLE PLAY LEFT OR RIGHT. MY VEHICLE IS UNDRIVABLE AND PARKED AT THIS TIME UNTIL I FIGURE OUT WHAT TO DO. I UNDERSTAND THAT GM ISSUED A RECALL FOR SUCH SAFETY ISSUES IN 2018. I JUST BROUGHT MY VEHICLE A YEAR OR SO AGO. PLEASE ADVISE, THANKS.

Safety Hazard. Fuel feed line is leaking from top of gas tank and running down beside tank, which can lead to vehicle fire or explosion.

the rear powerlift gate randomly closes while getting groceries bags out of the back of the car it can automatically close on a person a seriously injure them it as almost closed on us several time but we were able to get away quickly if a younger child or teen is using this is dangerous in the cold weather is seams to worsen the symptoms this is a very serious safety issue that needs to be addressed it has happened on numerous occasions seems to happen more in cold temperatures.
