The contact also stated that multiple other electrical defects would occur such as the backup camera activating while in drive(D), the instrument panel intermittently going blank, and various other defects. The vehicle was taken to the dealer on multiple occasions where they failed to duplicate the failure. The contact then stated that while driving at 80 MPH, the instrument panel went blank. The contact attempted to pull the vehicle over; however, an unknown turn-off of the vehicle warning message appeared on the instrument panel as a warning chime was also emitted from the vehicle. The contact then stated that the vehicle then came to an abrupt stop where the engine and brakes seized, while traveling at 34 MPH. Due to the failure, the contact was taken to the hospital where they were treated for whiplash, inflammation in the neck and spine, 7 bulging discs in the spine, and pain in various parts of the body. The vehicle was towed to a dealer where it was diagnosed with engine failure; the vehicle's engine was replaced under warranty. Despite the repair, the contact refused to take possession of the vehicle as they did not feel safe driving the vehicle.

On [XXX] while driving on the highway near Wash DC engine stopped, went to neutral. Would not start again. OnStar towed vehicle to Koons Chevrolet GMC Tyson in Vienna VA. 703 448 7221. On Tuesday Jan 7th, Koons Service Dept. looked at vehicle and determined that it was a thrown bearing and needed a new engine. There are 28,712 miles on vehicle. You can inspect if desired. Our safety was extremely compromised. We were on a 5 lane highway in the left hand lane going 65. Engine quit and we had to coast to the far right lane in heavy traffic. We almost got hit several times on the maneuver and rear ended on the side of the road from oncoming vehicles while waiting for a tow. Dealer has work order to fix the vehicle. Vehicle was not inspected by the manufacturer that we know of, nor the police or insurance representatives. Only inspected by the dealership. The only symptom before the incident was a dull sound like a plastic bag being stuck in the grill for a few minutes before incident. The Service Department said the parts are on a "Galactic backorder" which means they do not know when they will come in. GM is extremely uncooperative in assisting us with this issue. They will not repurchase vehicle, will not put in writing why they wont repurchase it. Will not provide any compensation until the issue is resolved, which could be months. It is an extreme financial hardship for me to cover my rental car (taxes and insurance for the rental car are not covered) and continue to pay the car payment and the insurance on a car that is not available to me. My case number with GM is [XXX]. I need my loan payed off or a repurchase for the original value of my car so I can purchase another vehicle.

While sitting at an intersection of a busy 4 lane road the engine stoped without warning and could not be restarted. Due to a poor design by GM, the Tahoe has no ability to be put in neutral when the engine isn-??t running. We were stuck at a busy intersection an almost hit multiple times, until a tow truck could come since it cannot be put in neutral and pushed. Dealer inspected engine and found it had been burning oil. The car never gave any warning lights that it was low on oil or that there were any engine issues. They did an oil change and gave the car back. The car was running, but within less than 5 miles of driving it it started to shake and make horrible noises. At this point, I was driving on the interstate. I was able to limp the vehicle back to the dealer. It was diagnosed by a dealer with spun engine bearing. I was told they were very close to seizing up and I would-??ve been stranded on the interstate with no shoulder. This could-??ve caused a major issue as I was on a busy interstate and the vehicle would-??ve locked up. There was no shoulder at this point due to construction. Through both of these issues the vehicle never gave any dashboard warning lights. There are two major design flaws. The engine has an issue with its bearings. Also, there needs to be a way to put the vehicle into neutral while the engine is not running. It is not safe to not be able to put these vehicles into neutral.

On 5/27/23 I purchased a new 2023 Chevy Tahoe RST with a 6.2L V8 engine. On 5/28/2024, between 5 and 6pm (rush hour) I merged onto State Highway 32 in Maryland. I accelerated to match the speed of traffic and moved to the far-left lane. I was traveling between 60 and 65 MPH when my vehicle shifted into neutral by itself. I was unable to shift the vehicle back into drive. There was no shoulder on the left, so I had to coast through 2 lanes of traffic moving at a similar speed to reach the far-right lane. I could have very easily caused an accident, injuring myself or others. After successfully pulling off onto the shoulder I was still unable to move out of neutral. I had to shut off my engine and restart the vehicle to shift it into drive. I was unable to recreate the failure and safely made it home. In the days following the incident, I began to hear a clicking sound when I accelerated. At no time did a check engine light turn on and my OnStar vehicle report showed my Tahoe was in good health, including the engine. I brought the vehicle to Criswell Chevrolet on 6/14/24 to service the vehicle. I was told later that afternoon that my vehicle required a brand new engine. The vehicle and engine are available for inspection upon request. I was awestruck that a brand new vehicle with 19,000 miles could possibly need to have the engine replaced. While conducting online research, I see that other 2023 Tahoe owners have had a similar experience.

Check engine light activated as well as dashboard lights. Was able to guide vehicle to side of road. Unable to start vehicle and was towed to local dealership.
