2023 CHEVROLET TAHOE Complaints

1 week and 1 day later we are stranded again on the side of highway going full speed in our Tahoe. We took it to two different certified Chevy dealerships and they gave us a vague resolution and this issusr is not fixed at all. Our engine is locking up on us at full speed on the highway. This vehicle has 83,000 miles on it and we’ve maintained this vehicle very well.

We were driving full speed down the highway and the vehicle completely shut down steering wheel locked and we were stranded for six hours. Turns out the dealer said it was just the battery and they fixed the grounding of the battery. I’m sorry but I’m not satisfied with this response. I’m scared to drive this vehicle.

A couple weeks ago, the truck suddenly started running rough and the front collision avoidance system failure message displayed. Immediately took it to the dealership. Computer read out showed #7 fuel injector failed. Repaired and was fine. Yesterday, 8/27/26, same thing happened again. Immediately went to the dealership. Now #4 fuel injector failed. Service manager just called and states that Chevrolet does not have that injector and on backorder with no date of expected delivery. No other Chevy dealer has #4 fuel injectors either. Tells me that there is an overwhelming demand for fuel injectors that indicates a defect. Meanwhile, the truck is out of service and GM is not addressing the issue to replace all the defective injectors.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was taken to a dealer, where the NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) remedy was completed with an oil change and oil cap replacement. Approximately three months later, while the contact's wife was driving approximately 45 MPH, the engine stalled. The driver was able to coast to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that the engine had failed. The engine was replaced. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 22,000.

I am writing to express my disappointment with how the L87 engine recall was handled on my 2023 Chevrolet Tahoe. I purchased this vehicle for approximately $82,000 and brought it to Kunes Chevrolet in Lake Geneva multiple times for scheduled maintenance. During my first visit after learning of the recall involving potential connecting rod and crankshaft defects, I specifically asked when my vehicle would be inspected and repaired. I was repeatedly told that I would receive additional information in the mail and that I would be contacted when repairs became available. Over the course of several oil change visits, I continued to ask about the recall. Each time, I received essentially the same response. During my most recent visit, I was informed that when the recall procedure became available, the dealership would listen to the engine with a stethoscope and then determine whether the vehicle required repairs or only a switch to a heavier oil viscosity. As a customer who invested $82,000 in a full-size SUV, I found that response extremely disappointing. The recall concerns involve engine components that could potentially lead to catastrophic engine failure. Being told that the solution may simply be listening to the engine and installing thicker oil did not inspire confidence in the long-term reliability of the vehicle. Ultimately, my confidence in both the vehicle and the handling of this recall deteriorated to the point where I no longer felt comfortable taking long trips with my family. I made the difficult decision to trade the vehicle in less than two years after purchase, resulting in an approximately $26,000 financial loss. I believe customers who invested significant amounts of money in these vehicles deserved clearer communication, a more proactive response, and a solution that restored confidence in the product. Unfortunately, my experience left me with serious trust concerns regarding both this recall process and General Motors' customer commitment.

ONSTAR module does not work. GM dealership claims the hardworking malfunctions and needs replacement for $800. Onstar is advertised as a safety feature that is now unable to be used.

My 2023 Chevrolet Tahoe (VIN: [XXX]) suffered a catastrophic failure of the 6.2L V8 L87 engine assembly — specifically the connecting rod and crankshaft components — at freeway speeds on [XXX], just 9 days after purchase. The original failed engine is no longer available for inspection as it was removed and returned as a core by Shaheen Chevrolet in Lansing, MI as part of the warranty replacement process. The only symptom prior to failure was a brief squeaking noise that began approximately 0.5 miles before the engine failed. No warning lamps, messages, or other indicators appeared at any point before the failure. The engine then failed suddenly and completely at freeway speed, causing immediate loss of propulsion. My family was left stranded in an unsafe roadside location until a tow truck arrived. Sudden loss of power at freeway speeds creates significant risk of collision for both the vehicle's occupants and surrounding motorists. The failure was inspected and confirmed by Shaheen Chevrolet as a GM manufacturing defect involving the connecting rod and crankshaft. No police, insurance representatives, or GM field engineers inspected the vehicle beyond the dealership. GM authorized a full engine replacement under Special Coverage warranty (10 years/150,000 miles). The replacement engine (GM part #12740076) was on national backorder for over two months due to supplier capacity constraints. A loaner vehicle was provided during that time. This failure occurred despite a prior GM recall addressing the same rod/crankshaft defect having been performed on this vehicle. The recall remedy was ineffective. I have no confidence the replacement engine will not fail again. With approximately 597,630 vehicles affected, this represents a serious and ongoing public safety risk.

My vehicle, 2023 Tahoe, previously had the GM Recall 25V-274 / N252494001 remedy performed (0W-40 oil swap) in October of 2025. Despite completing the manufacturer's official recall remedy, the engine suffered a sudden, dangerous loss of motive power at highway speeds when I was making an out of state move and traveling alone; it was terrifying. I had to have it towed to the nearest dealership and that is where it is now as I had to leave since I was in the middle of moving. I need a new engine. I have no idea how I will get my Tahoe to my new residence or when. The dealership was not open on Sundays so I had to find a place to stay after leaving my Tahoe full of my items and my bike. I was so afraid it would be broken into. I had an oil pressure warning right before the engine completely stalled. And, I was accelerating up an incline and it felt like my Tahoe couldn't get enough power to make the incline. My Tahoe only has 35,047 miles, and threw the Diagnostic Trouble Code P0016 through my ONSTAR app as well as with the tech at the dealership. And, I am having a lot of trouble with GM corporate with rental cars. I had to pay out of pocket in order to get back on the road with my belongings as I start a new job this week at my new home. I had to leave some belongings and my bike with my Tahoe at the dealership.

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)

I have a 2023 Chevy Tahoe with 45k miles. Today driving two kids home from our football practice I was driving along at around 40mph and all of a sudden the transmission downshifted and almost locked the rear tires up. If it was winter, wet, or cool, there is no doubt that the tires would have locked up. Check engine light came on, and now the vehicle wont move in reverse and at around 45-50 mph the engine is running at 3,000 rpms. I volunteer to be a youth football coach and always have a car full of children. This isn't normal or safe. P.s. I should've bought the Ford Expedition.
