Jun 20, 2026

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.

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

We were driving on the highway and the engine started making a ticking noise and AFM light came on. Took the car to the dealership for inspection and they said the lifter had collapsed and it would cost $1000 to tear the engine down to see if the camshaft was damaged. Asked for the estimate to replace camshaft and lifters and they quoted $10,000.

Our Tahoe was included in the recall. The dealership inspected it, found no issue at the time, and told us to switch to a different oil viscosity, which we did. This vehicle has only ever been serviced at a Chevrolet dealership. On August 20th, while driving on the highway, the engine shut off without warning and we had to coast to the shoulder. We attempted to restart it several times, but the engine would not hold an idle. After shutting off all accessories, including the A/C and radio, the vehicle finally started. We brought it back to the dealership for inspection, and once again they could not find any issue. Today, September 14, 2026, we heard loud clanking coming from the engine. We pulled over immediately and had the truck towed to the dealership. At this point, we believe the engine is no longer serviceable and will need to be replaced. We do not believe the change in oil viscosity is an adequate fix for the 2022 to 2024 6.2L engines covered under the GM recall, including the one in our Tahoe. An engine dying without warning at highway speed is a serious safety hazard, and we were fortunate it didn't end in a collision.

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.

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.

Jan 1, 2026

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.

My 2023 Tahoe HC 6.2L VIN Passed the Catastrophic Engine Safety Recall stating my Engine was SAFE. The dealership performed a change in oil velocity per GM's directives. Then the engine seized upon accelerating. No warnings, just dead, yet able to coast through a large intersection on a -20F day where NOTHING worked on the vehicle. Even though the engine would not turn over when hitting the Start button, it would only allow 15 minutes worth of Emergency Flashers before the sensors shut the vehicle completely down. We had to abandon the vehicle on the side of the road, with key fob in this NEW vehicle, hike to safety, and for warmth. Total mess up as how to tow the vehicle, even when I advised NOTHING (but SiriusXM) worked and could not put vehicle into Neutral. Had to wait almost a month for a Replacement Engine. Once Replacement Engine installed, I expressed how my vehicle did not feel, nor sound the same as the original. The dealership ensured that it was a 6.2L Engine Replacement, without being able to tell me where it came from, how many miles on it, or the serial number to this new engine. I was told to give it 500-1000 miles to allow Replacement Engine to "settle". Exactly 300 miles in, on the expressway, just coming out of a bottle neck slowdown, I got up to around 45-50 mph and it was like I hit an invisible wall! Vehicle lost propulsion. Seat belts locked. No brake lights since I was accelerating. Extremely thankful nobody was behind me. Obviously let go of the gas. Pause. Then I was able to drive the vehicle to a safe location off of the expressway, and shut it down. Immediately called dealer. Restarted, drove about 15 miles to safety, went to shut off and it would NOT turn off. Sounded as if trying to start it while already running. 20 min to turn off. 5 months at dealer, they could not mimic/see any issues, even though I could "feel" the loss of propulsion at lower speeds. Fearing ALL lives, I had to trade down yet more $

Jan 20, 2026

Rear wheels suddenly lock up momentarily during downshift at 30-50 mph (most reproducible 35-40). Transmission in a high gear (8th-10th); any throttle input commanding a downshift can trigger it: as the downshift executes, rear wheels briefly stop, skid with an audible chirp, vehicle jerks violently. Reproducible on demand, multiple times per drive, on video. Highest-speed event ~50 mph, family aboard. NO advance warning: no check engine light, no message, no stored code, no gradual onset. Traction control sometimes activates at the instant of the skid, sometimes not — always reacting to traction already lost, never before. A driver has no opportunity to anticipate or react. THIS IS A LOSS-OF-CONTROL HAZARD. It is especially dangerous in a turn, on wet pavement, or in traffic. Onset May 2026. Pursued repair since, across three shops: an independent, twice (no codes/leaks/abnormal findings; MAF replaced; unresolved; referred to dealer), then a GM dealer 3 days (test drove 34+ miles, no codes, fluid good, all shifts correct; declined recommended control-module recalibration, cause unconfirmed). Lockup recurred within 5 miles of leaving, same day; I returned immediately, asked for a tech ride-along while fresh — did not occur. Next day, a second GM dealer: tech note said fluid was low, though the same RO's inspection passed that fluid and found no leak; no leak ever identified anywhere. Paid $672 for a fluid exchange — unresolved. Days later, same dealer measured 265F on a 30-mile road test and condemned the transmission. Full replacement underway, largely out of pocket. Symptom matches recall 26V-085 (momentary rear wheel lockup, worn control valve, 10-speed/ETRS) covering 2022 models. My 2023 is not included. I am not asserting a diagnosis — no one has established the cause — but I ask ODI to consider whether that campaign should include additional model years. The failed transmission is available for inspection; videos available on request.

While traveling out of town on the highway,we had a sudden loss of power. My vehicle wouldn’t accelerate or shift. My check engine light came on and a message displayed that said something about reduced power. After limping to a dealership while in another city, I managed to wait hours for my husband to pick me and my children up. We waited several days for the dealership to tell us it was the valve body that needed replaced. My vehicle was NOT in the original recall for the valve body, although we experienced the exact same issues that the recalled vehicles experienced. This entire experience was horrifying. Along a stretch of highway that I was unfamiliar with, speed limits of 80mph, and a sudden, complete loss of motor power and speed, this could have someone. I had a vibration while staying at any constant speed for months prior to this, I had taken the vehicle in numerous times but was told the only thing to fix it was a software repair and that wouldn’t take care of the problem entirely. This vibration was and still is so bad that my phone will fall from the magnetic mount if I don’t let off the accelerator or increase acceleration. My vehicle still doesn’t seem to run properly but I am unable to get it to reproduce any issues when at the dealership. Extremely unnerving to travel with my family out of town or state and wonder if my fairly new vehicle will make it.

We purchase the vehicle in February of 26’. Certified preowned they a Chevrolet dealership. It was disclosed to us that the engine had been recalled and replaced in September of 25’ (had about 1500 miles put on it, before we bought it) due to the ongoing issues that plague the V8 6.2L motors. We put less than 3000 miles on the vehicle and wanted to take it in for oil change and new tires. My wife had heard a rattling/ticking sound and wanted the dealership’s service department to check it out. They test drove the vehicle and immediately told us that this second engine needed to be replaced with less than 4,500 miles on it. We’ve now had a loaner for almost 7 weeks while we wait for a new 6.2 liter engine that no one is even sure won’t have the same thing happen to it that the first two engines had happen. GM needs to correct this issue. I read that over 1100 6.2 liter engines are on back order. This is unacceptable.
