2023 Chevrolet Tahoe

When GM announced the recall involving the potential for catastrophic engine failure, I immediately contacted Bridgewater Chevrolet in NJ to schedule the required recall inspection. I was told the dealership could not perform the inspection because it had not yet received the required 'diagnostic tool' from GM. Once they received the equipment, they contacted me and on Oct 1, 2025, they completed the required recall inspection and informed me that my Tahoe had passed the recall inspection and that the vehicle was safe to continue driving. On XXX while driving over the Driscoll Bridge on the [XXX] with my daughter and our dog, the engine catastrophically failed without warning as I began to exit on exit [XXX] to [XXX] into heavy traffic. With no warning, the vehicle flashed that it was in neutral and then suddenly lost all power and stopped completely in a traffic lane, creating an extremely dangerous situation. After a few mins, I was able to get it started briefly, enough to coast along to a spot a few hundred feet away where there was a shoulder. From there the wheels locked and it would not move at all and windows would not open. It had to be dragged completely inoperable with locked wheels onto a flatbed three separate times. It was first dragged and flat bedded off the Parkway to a place we felt unsafe so we stayed locked in the car in July heat with no windows down, then to my mechanic and then to the dealership. I am unsure of the damage that may have caused. The dealership received the vehicle on XXX and within a day told me that it was indeed what my mechanic and they suspected - the catastrophic failure recall they had inspected and passed the vehicle for. As of today, XXX, I was told they just received an engine and can start a full replacement this week. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We had car checked due to strange and erratic shifting in less than a year of owning. Then took in for recall, they stated it was fine and performed the remedy with higher grade oil. Still had issues and took to another dealership to look at and they stated it was fine as well. About 2 months later while I was driving it was hesitating and would kind of buck and when I was about to turn on to a busy road it just stopped. I couldn’t do anything at all, the entire car was locked up. The tow truck driver couldn’t even get it into neutral to tow. Dealership said it’s the engine and it needs to be completely replaced.

At less than 50,000 miles, my alternator went out and had to be replaced, causing the battery to need to be replaced also. Now, at only 51,000 miles, my transmission is having problems and causing the vehicle to jerk when shifting. This vehicle has had regular maintenance performed by a combination of dealers and certified service centers since it was purchased brand new. I have never had this much trouble with a vehicle and am very concerned about it's overall safety and integrity, given the severity of the problems for something that is not old and does not have high mileage.

My 2023 Chevrolet Tahoe LS has experienced repeated service issues within the first year of ownership. The vehicle has been in the repair shop five separate times and out of service for approximately five months total. Due to extended repair periods, the mileage remains extremely low. A primary concern involved the steering system. The steering wheel was noticeably off-center while driving straight, requiring continuous correction to maintain proper lane position. Steering-related components were inspected and replaced. There were no warning lights present at the time. However, improper steering alignment raised safety concerns regarding vehicle tracking and stability. The vehicle has been inspected and repaired by authorized service providers. I am submitting this complaint to determine whether this reflects a broader safety-related issue with this model year.

Since 15,394 miles vehicle has experience multiple system failures upon vehicle startup. 2/24, 2/25, 12/25, 1/26. In all of these 4 instances the brakes become spongy/hard, steering wheel locks, and I am not able to control vehicle. Dash lights up; "Brake system failure - 43mph top speed", "Fwd collision system unavailable", "Service traction control", "Service ESC", "Service steering column lock", "Service brake pad monitor". Dealership has replaced, Telematic control module, Electronic brake control module (EBCM), Serial data gateway module, Park assist module and most recently they replaced the battery and cleared the codes to "fix" the same intermittent but recurring condition. In 11/24 Recall N242447990 was performed, reprogramming of Brake system control module and Serial Data Gateway Module, the exact same issue happened before and after the recall.

I purchased a 2023 Chevy Tahoe in Oct 2025. Since then, I have been trying to figure out how to set up the myChevrolet app. The OnStar button doesn’t work so I called OnStar. After multiple calls, they told me that the account is linked to the previous owner and can’t be transferred because of a faulty telematics communications module. The faulty module is also causing the clock to run slow, which indicates battery drain is beginning. The OnStar module failure poses a huge safety and privacy risk. Safety concerns include battery failure that can cause me to be stranded and the fact that the previous owner has the ability to start my vehicle at any time, even while parked in my garage posing a risk to my family’s health/life with trapped carbon monoxide building up. Privacy concerns include the previous owners ability to track my vehicle, lock and unlock doors, access my contacts, call log, location, and more. This is a significant risk. The dealership should not have sold me a vehicle with a defective module without repairing it and now refuse to fix it. This should have been included in GMs factory recall for 2023 Tahoe TCU’s or a new recall should be issued. Consumers should not bear the burden to fix a widely known safety, health, and privacy risk.

When I started my car at home, all of the dash warning lights came on, one after another. I put the car in reverse and started backing out of my driveway. I tried to stop but there were NO BRAKES! I slowly pulled back into my driveway and turned the car off. I had to take off work that day because I didn't dare to drive the car. The next day I started the car up and the check engine light was on. Luckily, I had brakes and I could go to work. Now, a day later, my engine light is not on. I made an appointment at the dealership. They can't get me in until mid February so I'm stuck with this problem, not knowing if the brakes are going to fail while driving. Oddly enough, when talking to a co-worker who has a 2023 Chevrolet Suburban, she recently had the same exact problem with her car. She has an appointment scheduled as well. I also read a complaint on this website that had identical problems. This car only has 8500 miles on it. It's still new! Someone is going to be killed or hurt very badly if this ever happens while driving. Please look into this.

As the owner of a 2023 Chevrolet Tahoe, I am currently experiencing persistent issues with the instrument cluster going dark and a severely malfunctioning GM 6.2L L87 engine. In November of the previous year, I encountered a sudden and alarming loss of engine power while traveling on a multilane highway at a speed of 70 mph. I successfully maneuvered the vehicle to a narrow shoulder, where I remained, accompanied by a Highway Patrol officer, for over three hours until a tow truck arrived. The GM certified dealership informed me that the engine was seized. The mechanics were unable to start or manually turn the engine. Upon removal of the engine’s oil pan, they found metal fragments in the oil. After having undergone an engine recall “fix” three months earlier, which included an inspection and oil service change to a more viscous 0W - 40, a new oil filter, and a new filler cap; in November, my engine failed and was replaced with a new 6.2L L87 engine. Initially, I was pleased with the repair, but I have since lost confidence that my car is safe after the new engine began exhibiting symptoms of a pending failure. The Tahoe hesitates on acceleration when merging with highway traffic, the engine dies when decelerating, the check engine light flashes at highway speeds, and the instrument cluster turns off at random. The vehicle that has been outfitted with a brand new engine is currently at the Chevrolet dealership; however, just like in August of 2025 during the Recall inspection, the mechanics there were unable to find any problems with their work or the new engine. They simply erased the stored P0300 engine diagnostics codes and ignored my evidence video, which showed the check engine light blinking at highway speeds. Despite the repair attempts, the issues have not been resolved, and the vehicle continues to pose a safety hazard.

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, Engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.
