2023 Chevrolet Tahoe Problems

6.2L L87 V8, connecting rod / crankshaft bearing failure even after I passed the recall inspection at a dealership. On [XXX], I was traveling approximately 55Mph and my engine completely shut off as well as the entire vehicle electronics. I lost power steering capabilities, and my brakes felt like they were kicking back at me. I was at crash risk from loss of power in traffic along with the loss of steering abilities, but I was lucky and was able to avoid traffic and get into the shoulder from 2 lanes away and slow to a stop. I got lucky because the loss of power steering made control extremely difficult. On [XXX], I brought my vehicle to All American Chevrolet in Middletown NJ for the safety recall N25249003 with 16,219 miles on my Tahoe. A few hours later I was called and said my engine was fine and passed inspection. On the day of failure, my car only had 21,111 miles on it. So, my engine still failed even after the oil change, and inspection process and it was extremely dangerous, after only 4,892 miles after their safety inspection.

I own a 2023 Chevrolet Tahoe equipped with the 6.2L V8 engine. The vehicle has experienced repeated significant engine problems, including a previous complete engine replacement and subsequent issues with the replacement engine. The original engine required replacement due to engine-related problems. Following that replacement, the vehicle developed lifter noise and required another extended stay at the dealership for repairs. The vehicle has now been out of service for approximately 4–5 weeks while the dealership attempts to diagnose and repair the issue. After the dealership completed work to address the lifter noise, the technician identified an additional concerning engine noise. The dealership has since reported suspected bottom-end damage in the crankshaft area and has escalated the findings to GM engineering for further diagnosis and repair recommendations. I am concerned about the recurring internal engine failures, particularly given that this is the second engine installed in the vehicle. These problems raise serious concerns about the reliability and safety of the 6.2L engine. A failure involving the crankshaft, connecting rods, or internal engine bearings could potentially result in sudden engine failure or loss of power while driving. The vehicle has been inspected by an authorized GM dealership, and the current suspected damage has been reported to GM engineering. The final diagnosis and recommended repair are still pending. I am requesting that NHTSA review these repeated engine failures, including failures involving replacement engines, and investigate whether there is an ongoing safety or manufacturing defect affecting these vehicles.

While traveling on I-684 at highway speed, my 2023 Chevrolet Tahoe with 43,000 miles suddenly shut off without warning and automatically shifted into neutral. I had a complete loss of propulsion. As a car guy who has been following the GM 6.2L engine recall issue, I suspected it could be that. I was traveling in the left lane and had to carefully coast across active lanes of traffic to reach the shoulder. My wife and two young children were in the vehicle, and the sudden loss of propulsion created a significant risk of collision. There were no warning illuminations, messages, or other symptoms that I observed prior to the failure. The vehicle was subsequently towed to my Chevrolet dealer for diagnosis and is available for inspection upon request. As confirmed by the dealer, the engine completely seized causing the loss of propulsion. I will also share, about 1 year ago after the GM recall was issued, I took my truck back to the dealer. They cleared the engine for the propulsion issue, changed the oil for 0W40 and changed the oil fill cap in line with GM recall standards.

"While operating my 2023 Chevrolet Tahoe at approximately 77,000 miles, the vehicle experienced a sudden, catastrophic electrical and mechanical failure. While I was actively pressing the brake pedal to slow down, the vehicle experienced sudden unintended acceleration and began to accelerate on its own. Simultaneously, the driver’s instrument cluster and the center dashboard infotainment screens went completely black and blank, resulting in a total loss of all critical driver information, gauges, and electronic systems. The vehicle fought against my braking efforts, creating an extreme crash and life-safety hazard. The vehicle is currently grounded and undrivable at a certified Chevrolet dealership. General Motors Corporate has opened an active investigation under Case Number 117203694. I am filing this report due to the severe and immediate safety threat posed by this total system failure.

Description of the safety problem On XXX, shortly after starting the vehicle and beginning to drive, I attempted to apply the brakes and discovered that they had essentially frozen up and were not functioning properly. At the same time the vehicle displayed the following warnings: Service ESC, ABS warning light, brake system warning light, "Trailer Brakes Disabled – Service Required," traction/stability control warning, and check engine light. I shut the vehicle off and restarted it. After the restart the brakes appeared to function normally again and most warning indicators disappeared. However, the check engine light remains illuminated, and I have noticed a slight hesitation when starting the vehicle. I have photographs of the warnings taken at approximately 21,029 miles. Relevant history This vehicle was purchased new. The original 6.2L engine suffered a catastrophic failure at approximately 18,685 miles while traveling at highway speed and was replaced under warranty. None of the current problems existed before that engine replacement. Since the replacement, the vehicle has experienced multiple electrical failures, including windshield wipers becoming inoperative while driving in rain, intermittent loss of electrical power and starting problems, steering-related and collision-system warnings, and tire-pressure warning discrepancies. During a recent dealership visit to Ourisman Chevrolet (service advisor [XXX]) for multiple electrical malfunctions, I was told the problem was simply that the battery needed to be charged. The problems have continued, culminating in the XXX braking malfunction. Request I am reporting this as a potential safety defect affecting the braking, stability control, and electrical systems of this vehicle, and I request that NHTSA record and review this complaint.

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

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.

On 4/23/25, the check engine light came on and the vehicle reduced power. It was taken to dealership and a warranty service was performed, L87 Engine loss of propulsion. The vehicle was in service for 90 days. On 7/15/26, vehicle shifted itself into neutral while driving on the highway, with 4 kids in the car. This is a safety issue for our family and all around us, as car loses ability to drive at interstate speeds. It would not go back into drive, needed to pull over and get towed to dealership. Dealership diagnosed it needed a new engine and radiator; it was in service for 60 days. On 10/10/26, vehicle shifted itself into neutral while driving with one kid in car while driving on the highway. Vehicle gave the "conditions not correct for shift" and would not go back into drive. Vehicle was shut off and was stalled on the highway, after a time of it being off, vehicle started back up and the check engine light was on. This is a safety issue for our family and all around us, as car loses ability to drive, once again, at interstate speeds.

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.

[XXX] occupant was sitting in the rear driver side bucket seat and operator was able to use the automatic buttons near the tailgate and fold down the seat onto occupant. Occupant received a bruise on the forehead and potential back injury. There should be a safety guard to prevent the chair from folding when an occupant or object is in the seat.

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.

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.

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.

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!
