2023 Chevrolet Tahoe Problems

I am submitting this complaint regarding my 2023 Chevrolet Tahoe equipped with the GM 6.2-liter V8 engine. VIN: [XXX]. At approximately 40,000 miles, the original engine experienced a major failure and was completely replaced by a Chevrolet dealership under warranty. I have now driven fewer than 10,000 miles on the replacement engine and am experiencing a very similar engine-related problem again. The vehicle is currently back at the Chevrolet dealership being inspected and repaired. This is extremely concerning because the original engine failed at only approximately 40,000 miles, and the replacement engine has developed a similar problem after fewer than 10,000 miles. The GM 6.2-liter V8 has been the subject of numerous reported engine problems and complaints, and I believe this repeated failure warrants NHTSA’s attention. I am concerned there may be an underlying or recurring defect affecting these engines that has not been adequately addressed. I am also concerned about the potential safety implications of an engine or valvetrain failure while driving. An unexpected loss of power or significant mechanical failure could create a dangerous situation, particularly at highway speeds or in traffic. I can provide dealership documentation showing the original engine replacement, the mileage at which it occurred, and the current repair visit. This documentation establishes that the vehicle has experienced significant engine-related problems twice within a relatively short period, including a similar problem with the replacement engine after fewer than 10,000 miles. I respectfully request that NHTSA document this complaint and review whether there is a broader pattern of premature or repeated failures involving the GM 6.2-liter V8 used in 2023 Chevrolet Tahoe vehicles and whether further investigation or corrective action is warranted. Replacing the original engine did not resolve the issue, as the replacement engine has now developed a similar problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power and was unable to restart. The message "Engine Overheating - Stop Driving Immediately" was displayed. The vehicle was towed to the dealer, who determined that the engine had failed, and the engine was replaced. The manufacturer was notified of the failure by phone. The failure mileage was 32,295.

I am filing this safety complaint regarding the sudden and unexpected transmission failure of my 2023 Chevrolet Tahoe at approximately 110,000 miles. My transmission failed without any warning, creating a serious and frightening safety concern. There was no advance indication that I was about to experience a major mechanical failure. A transmission failing unexpectedly creates the potential for an extremely dangerous situation, particularly when traveling at highway speeds, navigating intersections or driving in heavy traffic. I purchased this vehicle brand new and have consistently had it serviced at Bergstrom Chevrolet of Madison. My maintenance history includes approximately 20 dealership visits between January 2023 and July 2026. Despite this extensive service history, the transmission failed less than four years after I purchased the vehicle. I am extremely concerned that such a critical component could fail without warning. An unexpected transmission failure can put the driver, passengers and surrounding motorists at risk, particularly if the vehicle suddenly loses its ability to accelerate or maintain speed. The Chevrolet dealership diagnosed the transmission failure and provided an estimate of approximately $7,500 for replacement. I contacted General Motors to report the failure and request assistance. GM denied my request solely because the vehicle had exceeded its warranty mileage. When I asked whether the decision could be appealed, I was told no appeal was available. My primary concern is the safety implications of this unexpected failure. I believe this incident warrants investigation to determine whether other owners of 2023 Chevrolet Tahoes may be at risk of experiencing similar transmission failures without warning. I am requesting that NHTSA review this incident and determine whether a potential transmission safety defect exists.

My vehicle received a software update which has caused my OnStar (safety) option to malfunction and has stopped working properly. There is an active recall for some vehicles but for some reason my specific year is not listed as one of the years for recall but has the exact issue.

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)

It has not been inspected yet but will call the dealer tomorrow morning since I just this vehicle on Friday

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.

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 car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

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.

Following a GM-initiated over-the-air (OTA) software update on May 18, 2026, my vehicle's windshield wipers became permanently inoperable — stuck in the "on" position with no ability to turn them off. This is not a gradual mechanical failure or wear-and-tear issue. The malfunction began immediately and directly as a result of a software update pushed by General Motors. Because the wipers cannot be controlled, I have been forced to remove the wiper fuse to make the vehicle driveable. This means I am currently operating a vehicle without functional windshield wipers — a federally mandated safety system. I want to be clear: this unsafe condition was caused entirely by a GM software update, not by any action or negligence on my part.

For the third time, my windshield wipers quit working in the middle of a rain/snow storm. Have taken the vehicle into GM service under warranty twice, the first time they updated the software but that repair only lasted a few months. Second time they replaced the windshield sensor, that lasted a few months. Now today, driving home in the snow my wipers quit working altogether. The sprayer worked, the rear wiper on the same handle works, but nothing else I could do gets the wipers to work. This is a big safety concern as it has happened all while driving in I climate weather.

The contact owns a 2023 Chevrolet Tahoe. The contact stated while driving 10 MPH, the air bag warning light illuminated. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was made aware of the failure and was referred to the NHTSA Hotline to report the failure. The approximate failure mileage was 39,144.

Vehicle 1 pulled out into Vehicle 2s lane and cut them off causing Vehicle 2 to slam on the breaks causing My vehicle ( Vehicle 3 ) to collide into the back of vehicle 2. No emergency breaking a-curd and no airbags deployed durring contact at rate of speed of 45-60MPH. Total damage to Vehicle 2 rear end and total damage to vehicle 3 front end.

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.

Frequently getting warning message on main info display stating "Service Safety Restraint System". This is consistent with a message and service bulletin issued for 2021 Tahoes where there is an issue with the connector for the airbag under the seat.

I am submitting this complaint to report a potential vehicle safety defect involving the factory-installed running boards on a 2023 Chevrolet Tahoe. The running boards become extremely slippery during light snow or minimal winter precipitation, creating a significant risk of slipping while entering or exiting the vehicle. This occurs during normal use and does not require heavy snow or ice. I have experienced multiple near-falls despite stepping carefully, and the condition is repeatable. Given that the Chevrolet Tahoe is commonly used as a family vehicle and may be accessed by children, elderly individuals, or passengers with limited mobility, I am concerned that the running boards present an unreasonable slip hazard under common winter driving conditions. At this time, no injury has occurred; however, the frequency and severity of the slipping raises concern for potential injury if the issue is not addressed. The running boards are factory-installed and have not been modified. I am requesting that NHTSA review this issue to determine whether the design or materials of the factory running boards meet reasonable safety standards for normal winter conditions. Thank you for your attention to this matter.

Automatic life gate often closes when not wanting it to such as when loading from rear and reaching into vehicle foot comes near sensor or sitting with dog on rear bumper with gate open and dog passes near sensor these incidents have happened way to many timers

Breaks keep making noises and all four tires need to be forced balanced dealership won’t fix the issues

This Tahoe comes with a full size spare. This model includes Brembo front brakes. The included spare cannot be installed/mounted to the front axle as the wheel is undersized and will not fit over the brake calipers. None of my ordering information nor MSRP label or model information on Chevrolet.com points out the included spare tire/wheel cannot be used in all positions of the SUV. Finding this out at 5am in the dark and drizzle of a cold Michigan morning on the side of US23 southbound is not the least bit safe.

Second row right side seatbelt retractor broken and not bolted to C pillar from factory.

Tire is torn in the sidewall at the bead inside the rim edge. The tire had less than 10,000 miles on it and was installed on March 14th 2023, failing around [XXX] (around 9 months of use). It had been installed on a set of Chevrolet wheels before arriving at the dealership and that tire/wheel combo was installed on the Tahoe by Chevrolet in Fort Walton Beach, Florida. The tire failure appeared to occur without provocation and failed on a 2.1 mile drive from the store home. The tire on the rim was mostly covered by the edge of the rim and it was very hard to spot visually. There was no damage to the rim, nor any reason the tire might have been lacerated by the rim. Upon dismount for replacement, the damage appears to be a tear or rip and does not appear to be puncture damage. The tire was replaced at Chevrolet and they noted that there was no reason for the damage (and charging us for the failure). The tire was then shipped to Bridgestone and was returned to the Chevrolet dealer and it was explained that they said, "it happens". The only warning lamp that illuminated was the TPMS low pressure warning as the tire quickly deflated. I still have the tire in my possession for inspection. My safety was put at risk because the tear occurred during normal driving and without provocation. Luckily we were in the neighborhood and speed was 25 mph. Had this happened on the interstate, the outcome could have been quite different. This was a Bridgestone Alenza A/S 02 275/50R22 111H M+S dated 5022. Thank you!
