2021 Chevrolet Suburban Complaint Log

Multiple issues with transmission since owned. It randomly goes into "limp" mode and everything will blink and it won't start back. The transmission has always shifted hard and sounded funny they told me if was normal for the vehicle. Leaking transmission fluid when owned for 4 months. I have had to the dealer multiple times, several repairs, told it is safe to keep driving by GM. The inverter is bad and told me it was ok to drive until they can repair. GM will not give me a fair response or answer. The dealership won't buyback, and offered to purchase for nearly 30k less than I bought it for 18 months ago brand new. The engine light comes on and off randomly told me it was ok with a diesel it may do that when it gets cold.

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving 45 MPH, the driver’s side low-beam headlight was pointing inward, affecting his visibility of the roadway. The contact stated that the failure later occurred with the passenger’s side low-beam headlight. There were no warning lights illuminated. The vehicle was taken to the dealer who diagnosed that the headlights needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 62,000.

Car suddenly swerved, loud knocking started. Multiple system failures started flashing. Forward collision, ECS, traction control, the car was vibrating, jerky. I have multiple videos as well. The dealership literally told me they’d seen a ton of these when I called immediately and then told me to keep driving because the damage was done and if the engine died well then it’s under warranty. I have 3 children under 5 and that is NOT an appropriate answer when I asked about it being safe to drive considering it’s jerky/shaking/knocking, and has multiple systems down. I’ve also googled and joined forums and this is apparently a common issue in the 2021 V8s and Chevy refuses to issue a recall. Would be more than happy to provide videos as well it won’t let me upload them with the photos. Was told it could be weeks before they even have parts

Came to a stoplight and the car came to a stop. The car then automatically shifted into park on its own. The car would not shift out of park an the engine would not start. The car just died. Police showed up as I was in the middle of traffic and no one could even get the car to shift into neutral to push it out of the road. Very dangerous situation. Tow truck came and they could not even get the car in neutral. So they had to drag the car onto a flat bed. Dealer has examined the car. The starter was bad, the fuse box was bad but the major issue was in the engine where the lifters went out. To have the lifters go out at less than miles is unacceptable. The dealer commented that they are seeing this issue constantly from 2021 Chevy SUVs. This is a major safety issue in that there is no was to put my 2021 suburban in neutral when this happens to clear the vehicle from a busy highway. Please investigate this.

After getting it serviced for airbag issue at the blasius chevrolet dealership in waterbury, ct. A week later, the car was was shaking while driving back home for work, the ESC message came up, forward collision came up, and traction control message also came up. Dropped it off at the dealership and said it was bad gas. Two days later, I was told that the misfire is caused by the lifter and pushrod was broken and that another 2021 suburban came in with the same issue but was suggesting it was our fault. There has been alot issues L84 engine that the misfire is due to a collapse lifter with less than 20K miles.

Transmission leaked oil and the suv didn’t advice the loss of fluid. Still under repair

The lifter rods failed on my vehicle that has approximately 8,000 miles on it. The dealer said that this is a known issue and that there is a service bulletin out for it.

In traffic, approx. 10-15 MPH car in front stopped short. I put foot on the brake pedal and pushed the brakes pedal to the floor. The car did apply the brakes equally as hard as I was Appling brakes at the pedal

My seat belt recall was not done said they did but did not do it ask them when were going to do it would never call or answer me need them to complete there recall on rear seat defective

Drove up to a stoplight 4th car in a turn lane, came to complete stop. Some cars closed ranks a little further so i released my foot off the brake and moved up a few more feet and stopped again. The car then accelerated with brake fully depressed and wouldn't stop. I then put gear to neutral Tac was very high maybe 5000. Put car into park and then turned off the engine. Restarted car and continued on my way. Contacted Chevrolet and my dealership for a service diagnosis coming up July19,2021. No image to anyone but I have heard of this problem before a malfunction of electronics controlling the drivetrain. Can something be done before any injury or death occurs.

Purchased the new 2021 Chevrolet Suburban, 4 miles on odometer and left the dealer. Less than 20 minutes from dealer AC stopped working. Called dealer thinking it was small error. While on phone I looked under the vehicle which was now emitting foul burning odors. Noticed a very large amount of oil(1quart+) dripping from everywhere from engine to exhaust mid way down vehicle,oil cooler line was blown off. Towed newvehicle to dealer. Chevrolet wants me to keep this vehicle even though there was a TSB issued last year about this same issue. Chevrolet was supposed to fix before shipping vehicle and demanded dealers to do the same but did not follow its own advice. Now they want me the consumer to take a vehicle that now has 17 miles on it that has been repaired even though the issue was supposed to be remedied by manufacturer. GM/Chevrolet considers this a new vehicle even after major service for a known issue and wants me to marry this vehicle for 6 years of payments. I put down $22500 cash and this is the slap I get as consumer!

This evening while driving the windshield wipers started (while the wipers were in the off position). When using the turning signal it speeds up to approximately 3 times the normal speed. The display says the back hatch is open and the cargo light is on (the back hatch is closed). We turned off the car multiple times and the conditions persist.

We have had several incidents of issues with the engine and electrical system. There are as follows: - NO CHECK ENGINE LIGHTS and engine failed. - Engine continues to be sluggish and hesitant. Headlights do not come on when in "auto" and it is dark outside. - Doors lock with the keys inside and the engine is off. - Keys are showing in sleep mode or not present when they are present. The engine went down on May 6, 2021 and I was on the highway with 2 of my children. I could not accelerate. There was traffic and could not keep up. I was able to get the truck to the delearship to have inspected and repair attempted. NO check engine lights.

I WAS INVOLVED IN A 40 MPH FRONTAL IMPACT COLLISION WITH ANOTHER VEHICLE. THE INITIAL IMPACT OCCURRED ON THE DRIVER SIDE FRONT CORNER OF THE VEHICLE. DURING THE INITIAL COLLISION ME HEAD SWUNG SIDEWAY STRIKING THE B POST WINDOW AREA AND KNOCKED ME UNCONSCIOUS FOR A SHORT TIME. I THEN T-BONED A TRUCK AND FINALLY CAME TO REST AGAINST ANOTHER VEHICLE. AT NO TIME DID MY AIRBAGS (FRONT OR SIDE) DEPLOY. NOR HAS MY VEHICLE EVEN REGISTERED THAT I WAS INVOLVED IN A COLLISION. I REQUIRED MEDICAL ATTENTION AND WAS TRANSPORT TO THE HOSPITAL. AFTER EXAMINATION AND SCANNING/XRAYS, ETC. I HAD RECEIVED A CONCUSSION. I HAVE THE POLICE REPORT AS WELL AS MORE PICTURES IF REQUIRED. THE IMPACT WAS STRONG ENOUGH TO BEND THE FRAME ON MY VEHICLE.

WE WERE STOPPED AT A RED LIGHT ON FLORIDA STATE ROAD 54 TURN LANE TO GO ON US 75 WHEN THE OTHER CAR REAR ENDED US AND DROVE US INTO THE CAR IN FRONT OF US. NO AIR BAGS DEPLOYED. FLORIDA HIGHWAY PATROL CRASH NUMBER 88482185. WE ONLY HAD THE VEHICLE FOR 10 DAYS.
