Due to the failure, the contact used excessive force to steer the vehicle off to the shoulder of the highway where the vehicle was then towed to a dealer. After the vehicle remained in the dealer's possession for over a week, the vehicle was diagnosed with an engine failure. The contact was then informed that the vehicle was placed under recall the federal safety agency Campaign Number: 25V274000 (Engine) and that the engine would be replaced. Despite the engine repair, the contact stated that an abnormal, rattling sound would emit from the vehicle upon start of the engine. In addition, the contact stated that the vehicle would violently jerk upon depression of the accelerator pedal while at a complete stop. The failure started intermittently; however, the contact stated that overtime the failure became more persistent. The vehicle was taken to the dealer where they claimed that the transmission was four quarts low on transmission fluid; they then informed the contact that they could not guarantee that remedy would repair the failure. The contact stated that failure improved; however, she would still experience a slight hesitation upon depression of the accelerator pedal. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 39,000.

My 23 Chevy Tahoe was diagnosed with catastrophic engine failure on 04/02/2025, and per recall N252494000 a case for engine replacement. That replacement was completed and the case was closed on 06/02/2025. Since that time the new, replacement engine has been consuming oil at a high rate, is running with intermittent lag and I am waiting for a diagnostics appt with Chevy.

On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under manufacturer warranty. This was a serious safety incident involving loss of engine power at high speed.

The engine in my vehicle has experiences major failures in valve flap adjusters, multiple valve failures, valve cover issues, and over consumption of oil by over a quarter in a week and a half of average driving. My safety was put at risk because the engine failure resulted in traction control malfunctions while going 70 mph up hill on a major interstate. This led to extreme shaking which did not stop until slowing down to below 15 mph. Luckily I was a mile from an exit and was able to coast off the road quickly; it was decent enough weather, and I was less than 5 miles from my destination so I could creep between 15-30 mph to not exacerbate traction control alarms. That slow mph did back up traffic behind me. As far as I am aware the problem was likely reproduced by the dealership service tech, which led to their recommendation to replace the whole engine. They do not consider it to be covered by any warranty anymore. The engine may be in their possession still, but I am unsure. There were zero warning lights/prompts from the vehicle that anything was going wrong prior to the shaking and loss of traction control at high speed. The dealer service team suggested that my high miles led to the engine failure. I do highway driving with it and have followed all manufacturer recommendations for oil changes, and even more frequent changes with OEM oil since about 80k miles. I do not think this engine should have failed at this amount of mileage. I made note of oil consumption around 95k miles and measured oil loss regularly. It was a little less than a quart every 2K to 3k miles which manufacturer states is within spec so I would top off oil. A year ago it had a TCM wire replaced after burning in half. 3 weeks ago I also had to replace the entire turbo. The wire rendered my car unable to go in gear. The turbo failure put me into limp mode. I think the turbo failure was a sign of a deeper issue that went undiagnosed.

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.

At 5000 miles after the last oil change, my low oil light came on, took it to my local mechanic and he said it was 3 quarts low. took it to the dealership and they say this is normal but have me to a check every time i put gas up to 2000 miles. bring it back and they say its one quart low and this is normal. The attendant at the dealership says he sees this often and knows its frustrating but thats GM policy and there is nothing he can do. I do not think this is normal and have searched on the internet and find that many people have this problem. I do hope this is looked into because i feel like this is an issue and GM doesnt want to have to fix it because of cost
