2021 Chevrolet Tahoe Owner Complaints

May 6, on vacation, sudden engine failure, valve lifter and lifter rod. GM told dealer only to replace lifters on one side, Cyl 5 was problem. May 24 car ready, pickup and 68 miles later same problem while on I95 in SC. Did not trust engine and drove in right lane. GM played Russian roulette with our safety and that of other people on road. Sudden engine failure can result quickly in accidents with possible casualties at highway speeds. After pulling of I95, called GM Road assistance. Towed to dealer. They were of no help. Family member from CHS , SC send trailer to bring us all the way home in New Smyrna Beach Fl. While on phone with GM Road assistance we idled the engine to keep cell phone charged. Suddenly engine stopped and on restart heavy smoke came from tail pipe. May 25 car delivered to dealer in NSB where we bought car. May 27 they informed us same lifter/rod problem occurred on other side. Look at Chevroletforum.com and you will see 2021 6.2 engine having these problems within 8000 miles. Have been in contact with GM customer Assistance Center since May 14. We do no longer trust this engine. GM already decided to redesign the lifters as they are aware of the problem. NO recall has been issued yet. Consider this a serious highway safety issue. Do not consider the car a lemon, but yes the engine sure is.

We have owned this 2021 Chevrolet Tahoe for a little less than a year. Since acquiring this vehicle, there have been multiple safety recalls and we have had to get the vehicle serviced 3 times due to electrical issues. Now for the major safety issue, was out of town waiting at a red light in a turning lane. As we were waiting, the Tahoe spontaneously turned off. All of the indicator lights on the dashboard were illuminated and my husband tried to restart the car but the engine just kept turning and the car would not start. We put the hazard lights on and wanted to get the vehicle out of the road where there was active traffic. However, the vehicle was unable to be shifted to neutral so we were stuck and also important to note the hazard lights were not working. We towed to the nearest dealership and tow driver had to apply WD40 on the ramp to get the truck off since it wouldn't shift to neutral. At the same time, my husband received an email from OnStar "An issue with the Engine and Transmission System in your 2021 Chevrolet Tahoe has been detected." Now being told by dealership this was caused by a fuel pump module cut off, causing the car to go into "limp mode" so who knows what is true. I do not feel safe driving this car nor having my kids in it. This would be a very different conversation if this happened on a highway. This vehicle should be recalled because someone gets killed.

We purchased this vehicle on 11/28/20, and on 12/10/20 began receiving multiple error messages and loss of power on the accelerator. Shortly after the error messages began I was no longer to even start the vehicle. It needed to be towed to the dealer and eventually required a full engine replacement, and was out of service for 22 days. On 5/19/21 I was getting on the highway with my wife and 3 young children and began receiving many of the same error messages. The car was brought to the dealership the following day and I found out that this was another major engine issue. They need to order several parts, one of which is on backorder. As of 5/24 it has been out of service for an additional 5 days, bringing the total up to 27 days out of service, and there are currently 4800 miles on the car.

While driving on a residential street during daylight hours, on a clear day at approximately 20 miles per hour the right wheel on my car dislodged.  This caused me to lose control of steering the vehicle and strike a parked car.  There were people walking about on the sidewalk at the time and other cars traveling.  When I exited the car I saw that the passenger side was completely on the ground and there were broken pieces and liquid coming from underneath the car.  The axel was broken with a clean break.  The car was then towed to the dealership where I was informed it could not stay.  My insurance company then towed it to their repair shop where upon assessing the damage they could tell that this was not caused by a collision.  General Motors along with our independent investigator examined the parts and vehicle. Leaving me without a vehicle for 4 months.  Our Insurance investigator determined this was a defect in manufacturing and GM did not agree.  General Motors will not communicate with us any further on this matter.  Some of the repairs that were made was the left front and CV axel, also the left front aluminum steering knuckle was missing.  This should be investigated for metallurgical discrepancies by an independent lab.  While the car was being inspected there was a recall to the power steering that may apply to the vehicle.  I would like for the NHTSA to investigate this issue.  The car has been repaired and is in my possession and my insurance company has all of the reports, documents, and parts regarding the investigation.  I also have pictures immediately following and a witness to the incident. Had a been traveling on a highway at a higher rate of speed this could have been fatal.  Your assistance in this matter would be greatly appreciated.

I WAS DRIVING EAST BOUND ON I-10 IN SOUTHWEST ARIZONA AT ABOUT MIDNIGHT AT 75 MPH WITH CRUISE CONTROL WHEN BOTH HEADLIGHTS SUDDENLY WENT OUT; VISIBILITY WAS SUDDENLY ZERO. I PULLED BACK ON THE BRIGHT LEVER AND MY BRIGHTS CAME ON GIVING ME VISION. I CHECKED THE LIGHTS KNOB AND THE LIGHTS WERE TURNED OFF. I TURNED THE LIGHTS ON AND THEY FUNCTIONED NORMALLY. ON ANALYSIS LATER I THINK WHEN I MOVED MY FLEXED KNEE TOWARD THE DOOR MY KNEE CONTACTED THE LOWER PART OF THE LIGHT KNOB AND TURNED THE LIGHTS TO THE OFF POSITION. THE LIGHTS KNOB IS LOWER AND CLOSER TO THE CENTER COMPARED TO OTHER PREVIOUS TAHOES I HAVE OWNED MAKING IT EASIER FOR THE DRIVER'S KNEE TO MAKE CONTACT WITH THE LIGHTS KNOB SO THE LIGHTS CAN ACCIDENTLY BE TURNED OFF. I SOLVED THE ZERO VISIBILITY IN A FEW SECONDS. IF IT WOULD HAVE TAKEN ME 5 OR 10 OR MORE SECONDS I COULD HAVE BEEN KILLED. DRIVERS OF THIS 2021 TAHOE SHOULD BE WARNED THAT THEIR KNEE COULD TURN THEIR LIGHTS OFF AND THAT IF THAT DOES HAPPEN PULLING THE BRIGHT LEVER OR TURNING THE LIGHT KNOB BACK ON CAN CORRECT THE PROBLEM. IN THE FUTURE THIS LIGHT KNOB SHOULD BE CHANGED; PUTTING IT HIGHER AND MORE TOWARD THE DOOR WOULD BE BETTER OR ANYWHERE IT CAN'T BE ACCIDENTLY TURNED TO THE OFF POSITION. THIS IS EXTREMELY DANGEROUS AND PEOPLE COULD BE KILLED! PLEASE WARN THE DRIVERS OF THE 2021 TAHOE AND ANY OTHER VEHICLES WITH SIMILAR LIGHT SWITCH DESIGNS AND MAKE CORRECTIONS WITH THE LIGHT KNOB IN THE 2021 TAHOE AND VEHICLES WITH SIMILAR DESIGNED LIGHT SWITCHES.

at 13,540 miles, the drivers headlight started pointing to the ground instead of out front of the car. The headlight adjuster screw (inside the complete headlight assembly) had failed and was replaced under warranty. Then again at 35,250 mile the same thing happened again. Dealer claims GM will not do a goodwill warranty and wants $350-400 to take the headlight assembly off he car and send pictures to GM to see if GM will assist with replacement costs. Obviously this is a manufacturing defect or quality control issue. As 90% of my driving is done at night, it is unsafe for me to drive this vehicle at night.

Vehicle is displaying service safety restraint system error message which may affect airbag deployment.

It’s happened about 10 times since I’ve owned the car but the dealer can’t recreate it so we are out of luck. The vehicle accelerates on its own. Scenario 1…with constant light steady acceleration, it will lurch forward like I’ve stomped on the accelerator a bit, for about a second then go back to my normal input. Scenario 2, same lurch but this time while coming to a stop at a stop sign WITH MY FOOT ON THE BRAKE PEDAL ONLY. scenario 3…I’ve been using the adaptive cruise control and had it disengaged by braking, coming to a stop, then parking and turning the vehicle off. Then after getting back in and starting up and slowly pulling forward, the cruise control suddenly and abruptly renegages and attempts to accelerate to the last demanded setpoint. Image this scenario pulling out of a spot at a crowded gas station with pedestrians. I almost ran someone the hell over just now at the gas station and I’ve had enough. The dealer won’t do anything and when I called Chevy engineering they put zero effort into it, it was a 20 second phone call stating if it can’t be reproduced at the dealer there’s nothing they can do. This is absolutely completely 100% dangerous and unacceptable

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving 65 MPH, the vehicle experienced phantom braking and stopped suddenly. The adaptive cruise control warning light was illuminated. The contact stated that after several minutes the vehicle started operating normally. The vehicle was taken to the dealer however, no cause for the failure was found. The manufacturer was not contacted. The failure mileage was 10,000.

There is a serious cabin air pressure issue in this vehicle. When driving at any speed with the windows up, there is a booming inside the cabin, as if the passengers are inside of a subwoofer. My theory is that the headliner panel has too much flexibility in it due to the ceiling air vents. When driving, it is likely the headliner is bouncing up and down, creating the booming air pressure. Within 2 weeks of delivery of this new car and daily driving, my passengers and I developed serious ear issues which we attributed to the car. It got to the point where I would immediately have pain and ringing in my ears just driving a very short distance. None of my other cars including SUVs cause or have ever caused this issue. It is important to note that with all 4 windows rolled down, the problem does not happen. It's only when the windows are up. I have the LS trim without the sunroof.

7/15/2021

Sunroof continues to collect water in the drain. I have had it blown out but it continues to happen. It is a matter of time before it begins to leak into the truck. In my research, this is an extremely common problem/design flaw.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at approximately 35 MPH, he heard an abnormal sound coming from the front tires. The contact stated that the abnormal tire sound was constant and was occurring at various speeds. Additionally, the contact stated that the vehicle was occasionally failed to start. The contact stated that there was no starter motor sound or even the sound of clicking when the ignition key was turned. The contact stated that the failure was intermittent. The contact had taken the vehicle to a local dealer, where it was diagnosed; however, the failure could not be duplicated. The vehicle was not repaired. The contact stated that the failure had reoccurred. The manufacturer was informed of the failure. The failure mileage was 45,844.

The dashboard for the vehicle loses all power and does not regain power/connectivity. I've had this problem "fixed" 5 times by the Chevy dealership and the issues continues. They've replaced the entire dash, checked electrical components, changed out the electrical bank, and the issues continues. Driving down the road at 65 mph to have your dash go out is not only terrifying but extremely dangerous! I have no idea how fast I'm going, how much gas I have, no situational awareness related to vehicles that are close by... the ENTIRE dash goes out. This is a brand new 2021 Chevy Tahoe... I bought it with 4 miles on it and within a month of the purchase, the vehicle had this problem.

9/26/2022

2 ISSUES - 1) vehicle repaired 5 times for "transmission" problem by replacing wiring harnesses. On 5th attempt, the GM factory part or the technician caused the Tahoe to catch fire. Worst part is that it happened 1 hour after test driving and parking the car at their dealership, thankfully, I would normally have driven it home and it would have destroyed my home too. GM investigated and was unable to determine cause. 2) each time the "transmission" error occurred the GM car went into what they call the "limp" mode. The car immediately loses speed control and drifts to about 35 mph until you have control of the accelerator. I was on an interstate going +70 mph to pass a semi and immediately after passing the car went into Limp Mode, the semi nearly rear ended me and then passed me blowing his horn and cursing me. GM could certainly correct this latter issue by creating a warning on the screen that gives the driver ample time to pull over and address the problem as they do when DEF fluid (this was a diesel) is low and will give warning to add DEF or reduce speed after so many additional miles are driven. The former issue needs to be addressed immediately too, I've noted 4 other drivers on social media that had similar fires. Both of these issues could have resulted in serious injury to me or my family.
