While driving in traffic the car shut off, engine stopped. When the car stopped it went into park. Could not restart the car. Starter worked and engine started but ran very rough then stopped several times. I could not completely shut off the car in an attempt to basically reboot. Car had to be towed to the dealer.

Received an Over-the-Air update that rendered my vehicle unless. My vehicle would no longer start, or power on, or power on in accessory mode. It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer. With the electronic Parking Brake engaged, GM had a hard time trying to find a tow truck that wouldn't just drag the vehicle down my driveway and onto a flatbed.

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.

The vehicle was manufactured with a push button transmission gear selector. If there is an electrical issue(ie. dead battery, electrical short, engine failure, etc) you cannot shift transmission gears. If I pull into my garage, notice a burning smell coming from engine area, possibly an electrical short, I cannot put vehicle in neutral to push out of garage in case it does erupt into a fire and not burn down my house. Recently my dead battery caused the tow company to lift the back end and pull it our of garage. General Motors did not install an override to put transmission in neutral in an emergency. The transmission will only shift if the engine is running. Imagine driving on a road or stopped at a traffic light and the engine stalls, will not restart, good Samaritans offer to push you off the road, but can't shift to neutral. Dealerships have a hydraulic lift they place under rear tires to move vehicle around service area. As a retired law enforcement officer, many times we had to move vehicles out of the way until wrecker serviced arrived. I feel this is definitely something that has to be addressed and corrected before major damage occurs or lives are endangered.

Traction control and forward collision warning lights stared to go crazy in August 2021 (3800 miles), five months after buying my Tahoe. Sales rep indicated his new 2021 Silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) This time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly.

I purchased a 2021 Chevy Tahoe from Autonation Chevrolet 11-3-2020. I have taken my Tahoe to the service department numerous times - as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do NOT feel safe driving my Tahoe with the SRS light on. There's obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at Autonation Chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support.

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.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle idled and loss power. The contact detected a smoke odor and smoke came inside the vehicle from the rear seats. The service ESC, traction control, forward collision, and engine warning lights were illuminated. The vehicle was towed to lindsay Chevrolet (15605 jefferson davis hwy, woodbridge, va 22191) and diagnosed that the sensors were faulty and had the engine coil replacement. The contact received the vehicle back from the dealer and was driving in the dealer's lot when the failure recurred. The dealer informed the contact after diagnosis that the modular system needed replacing. The vehicle was still at the dealer and not yet repaired. The manufacturer was made aware of the failure and informed the contact that they would contact the dealer to see what the diagnostic was and what was repaired. The failure mileage was 2,502.

Vehicle will not start. Only 6900 miles. Battery fine, lights and radio work, windows and tailgate work. Car turns over, but just won't start. Read manual, did everything suggested. Clearly an electronic error. And, because vehicle could not be started, it could not be put in neutral. Tow driver had to drag car across pavement on flatbed. Could not be good for brakes or anything else down below. When arrived at dealership, could not get Tahoe off flatbed. Winch only pulls up onto flatbed, does not push backwards. Oiled the flatbed and shook the entire tow truck body to try to get it to slide down. No idea why this happened. But a couple of months ago same thing happened to a friend's GMC version. Clearly electronic failure in band-new car.

Tahoe

  • 1,367 miles
Brand new 2021 Tahoe 1367 miles catastrophically lost power without notice while in a busy intersection with mother and son. Onstar emergency services did not work. Unable to place car in neutral to move out of busy intersection. Police called, vehicle towed. Could not start, jumping not successful. Towed to dealer (hendricks Chevy 12050 w broad street richmond va 23233). Chevy certified mechanic stated cable from battery to alternator had burned/melted/fried, car lost power, no warning. Wanted to simply "replace cable" and "get me back driving." Fearful of major/larger electrical issue causing fire/electrical failure.
