2023 Chevrolet Tahoe: won't start

Filed Jul 30, 2026 · Engine · IL

My 2023 Tahoe HC 6.2L VIN Passed the Catastrophic Engine Safety Recall stating my Engine was SAFE. The dealership performed a change in oil velocity per GM's directives. Then the engine seized upon accelerating. No warnings, just dead, yet able to coast through a large intersection on a -20F day where NOTHING worked on the vehicle. Even though the engine would not turn over when hitting the Start button, it would only allow 15 minutes worth of Emergency Flashers before the sensors shut the vehicle completely down. We had to abandon the vehicle on the side of the road, with key fob in this NEW vehicle, hike to safety, and for warmth. Total mess up as how to tow the vehicle, even when I advised NOTHING (but SiriusXM) worked and could not put vehicle into Neutral. Had to wait almost a month for a Replacement Engine. Once Replacement Engine installed, I expressed how my vehicle did not feel, nor sound the same as the original. The dealership ensured that it was a 6.2L Engine Replacement, without being able to tell me where it came from, how many miles on it, or the serial number to this new engine. I was told to give it 500-1000 miles to allow Replacement Engine to "settle". Exactly 300 miles in, on the expressway, just coming out of a bottle neck slowdown, I got up to around 45-50 mph and it was like I hit an invisible wall! Vehicle lost propulsion. Seat belts locked. No brake lights since I was accelerating. Extremely thankful nobody was behind me. Obviously let go of the gas. Pause. Then I was able to drive the vehicle to a safe location off of the expressway, and shut it down. Immediately called dealer. Restarted, drove about 15 miles to safety, went to shut off and it would NOT turn off. Sounded as if trying to start it while already running. 20 min to turn off. 5 months at dealer, they could not mimic/see any issues, even though I could "feel" the loss of propulsion at lower speeds. Fearing ALL lives, I had to trade down yet more $

Space does not allow for a complete statement. However, here is a summary. I purchased my 2023 Tahoe on 07/19/23. On 07/27/23, the check engine light came on. Since then, there have been approximately 8-9 instances where the check on. Each time I took the vehicle in for service, however, the check engine light kept coming back on. There have been 2 instances in 2026 where the vehicle would not start, and then the check engine light came on. A Chevrolet dealer service advisor told me that this is a known issue with GM and Chevrolet; however, no remedy has been found yet.

While traveling at 55mph yesterday, I experienced a full engine failure which shut the car off fully while traveling on a single lane double yellow road. I was able to coast to a secure location. The car will not start or go into neutral. There were no warning lights that occurred at any time prior to the failure. This all occurred while on vacation 2 hours away. I previously went to the dealership for the recommended "fix" for the recall but that obviously did not solve the problem. This was an extremely unsafe situation for me and my family. I also encountered towing costs and significant loss of time. In addition, the car is at a dealership over 2 hours from my home. Chevrolet should be held accountable well beyond a recall notice which didnt solve the problem.

We were driving down the highway at around 77 miles per hour. I noticed that the vehicle chimed as though I initially got into it and needed to start the engine. I saw the dashboard asking me to start the engine. I attempted to start it while we were coasting to a stop, but it wouldn't start. I was able to barely get out of the lane of travel and avoid a collision. I tried to turn off the vehicle and turn it back on but it would not start. It would not even turn over. The vehicle eventually cannibalized the battery because it would never shut off.

We were driving on the highways, we had to break and the car shut off, we barely made it to the side of the road and the car would not turn over, start, or go in to neutral, which was very unsafe. Had to have it drug on the tow truck since it wouldn’t go to neutral and at the dealer it had 17 codes. The engine seized and they are having to order a new engine.

I was driving in the fast lane and all of a sudden my car went into neutral. Thankfully, my children were not in the car and I was able to merge over safely to the side of the freeway. after as I barely pulled off the car completely shut off. I tried to turn back on several times but would not start back up. I had my Tahoe towed to the dealership, and they told me the engine seized up and was a failed engine. Dealership ended up ordering another engine and it was missing some sort of plug that failed and had to replace again!

The vehicle shut off on the expressway causing a very dangerous situation. After several attempts it would not start again. I had to have the vehicle towed to the dealer and they advised me the engine has seized up. Most likely they told me the engine blew and will need replacing.

GM will not repurchase the vehicle or tell me when the vehicle can be repaired. Will not provide any compensation until the issue is resolved, which is unknown and 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]. GM has sent me to three representatives. Jonathan Phone Number: 1‑866‑790‑5600 Extension: 5927263 (Chevrolet Customer Assistance) Tomorra (866) 790-5600, extension 524688 (supervisor) Janet (866) 790-5600, extension 5910608 (part delay department) None of the reps have given me any assistance with my situation. They just kick me down the chain to someone else that cannot assist me. I simply need my car fixed, loan payed off or a repurchase for the original value of my car so I can purchase another vehicle. Can you direct me to any assistance? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.
