  I asked the dealer for information about the L87 6.2L engine rod bearing failure recall. I was told that they wouldnt perform the work until i recieved a letter from GM. This was when i got my first oil change. Then every oil change after that i asked the same question. At 43401 miles i parked the vehicle and havent driven it since. I am afraid to have something happen to me or my family. I paid $82,000.00 for a vehicle that GM's fix is to add thicker oil. I think that the rods and bearings should at least be visually inspected. The dealers maintenance manager at Kunes Lake Geneva says theyll listen to it with a stethescope. If it sounds ok theyll change the oil. I paid way to much to chance my familys safety on thicker oil. To make the situation better the vehicle blue books for $56,000.00 IT DEPRECIATED $26000.00 IN TWO YEARS. That is unacceptable.

  Driving down a street we heard a loud boom almost sounded like something exploded We looked around but saw nothing. Then started hearing noises from the sunroof Sure enough it had exploded Not cracked And it is smashed outwardly not in therefore not something that hit it or caused impact from the outside in. We researched it and seems to be a known ongoing issue. Very dangerous as it is happening more and more. It definitely startled us and could have been a scary situation if we had been on the highway. Also dangerous if that glass falls on you while driving.

  While Driving to my appointments via the freeway, all of a sudden the vehicle slowed down, I noticed most of the warning lights were on including the check engine light that was blinking. I Happened to be near a GMC dealership which previously did repair work on my vehicle and left it with their service center for a diagnostic inspection. A week later my service advisor contacted me with their Vehicle condition report that my vehicle had camshaft and internal engine group issues. He quoted repairs but recommended replacing the engine. Repair or engine replacement $21,296.51. Six months before this issue I had the same issue the warning lights and it resorted in replacing the brake control cylinder. Once repaired no issues/messages or symptoms with my vehicle until this current engine problem/replacement.

  On 12/3/2025, I moved my car in the driveway at 11:15am EST without any issue. At 6pm EST, myself and 2 young daughters got into the car to head out an hour away. As I went to drive away, I stepped on the brake and the car did not immediately stop…the brakes failed and came to a rolling stop. At that moment all types of warning and lights lit up the dashboard. I placed the car in park exactly where it was in the driveway and left it. I also tried to select the Ebrake and it would not engage. I called the dealer first thing the next morning as that had been closed at the time it happened. I was told to bring it in and not to drive it so nobody in my car or else would be at risk. The car was towed at my expense to the dealer. When I got in touch with the dealer that afternoon to get a status. They advised the believe the BCM needed to be updated because it seem to not be communicating properly but wanted to keep it over night to retest it before they sent me home with it. Going to point out several things…thankfully I had not left my house, as I live on a mountain and should that have happened while descending it could have been catastrophic. No warning or anything that the brakes would fail! According to records it shows the did a recall update back in Feb 2025 regarding the BCM- however, how are we sure it truly was fixed or was defective. GM/Chevy needs to take accountability for this defect and safety hazard that could result in death. In reading forums, I am not the only one this has happened to

  This is a brand new vehicle with a known problem to GM yet they keep selling them and admit they cannot fix it. The audio system, including the blinker sound, is warning systems and hands free phone capabilities do not work properly, if at all. This is a distraction while driving - especially when it comes to phone use. It is deceptive and putting public safety at risk, not to mention costing consumers thousands of dollars. Their built in safety system (onstar) cannot be accessed due to lack of audio rendering it useless in a crash/emergency which is a selling point they tout. I do have video of this occurring. Dealership says they cannot repair and that consumers are just stuck with expensive vehicles they cannot rely on.

  I bought this 2023 Chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

  2nd Powertrain failure in 4 months in 2023 Tahoe with 6.2L engine. The first being the Camshaft and lifters failing at highway speeds, which was repaired. The second issue the engine seized while on a tollway going approx 70 MPH with my spouse, children, and family in the vehicle. We were able to coast to the shoulder while waiting on a tow truck. Because of the engine being seized, the Tahoe is waiting on the engine to be replaced. While we wait, we were told they have no loaner vehicles and there are no GM rental vehicles available with who they contract through. Having a 2023 leased vehicle fail twice in 4 months with children in the vehicle is unacceptable and brings to question the safety and reliability of the vehicle moving foreward.

  The engine in my vehicle has experiences major failures in valve flap adjusters, multiple valve failures, valve cover issues, and over consumption of oil by over a quarter in a week and a half of average driving. My safety was put at risk because the engine failure resulted in traction control malfunctions while going 70 mph up hill on a major interstate. This led to extreme shaking which did not stop until slowing down to below 15 mph. Luckily I was a mile from an exit and was able to coast off the road quickly; it was decent enough weather, and I was less than 5 miles from my destination so I could creep between 15-30 mph to not exacerbate traction control alarms. That slow mph did back up traffic behind me. As far as I am aware the problem was likely reproduced by the dealership service tech, which led to their recommendation to replace the whole engine. They do not consider it to be covered by any warranty anymore. The engine may be in their possession still, but I am unsure. There were zero warning lights/prompts from the vehicle that anything was going wrong prior to the shaking and loss of traction control at high speed. The dealer service team suggested that my high miles led to the engine failure. I do highway driving with it and have followed all manufacturer recommendations for oil changes, and even more frequent changes with OEM oil since about 80k miles. I do not think this engine should have failed at this amount of mileage. I made note of oil consumption around 95k miles and measured oil loss regularly. It was a little less than a quart every 2K to 3k miles which manufacturer states is within spec so I would top off oil. A year ago it had a TCM wire replaced after burning in half. 3 weeks ago I also had to replace the entire turbo. The wire rendered my car unable to go in gear. The turbo failure put me into limp mode. I think the turbo failure was a sign of a deeper issue that went undiagnosed.

  We have a chevy with the 6.2 V8 engine. First we were at a stop light on the highway and the car shifted into Neutral and would not come out for two light cycles. My wife and children were stuck at the light with car's swerving around them at 65+. Finally it shifted into Drive. We called the Chevy dealership and they said it would be a month before they could look at the car and there were no check engine warnings. Two days later my wife and family were driving down the highway and suddenly it started making a flapping sound from the engine bay and was losing power. She pulled over and turned off the vehicle to see if that changed anything. The car would not restart and the check engine light was on (solid not flashing) it would just try to turn over with no success. We had it flat bed towed to the chevy dealership where they told us the engine was blown and that it had thrown a rod. We have 3900 miles on the vehicle and I would say this is a significant safety issue given that it can disable the vehicle on a busy highway.

  on [XXX] we bought our 2023 Tahoe High Country from Jeff Gordon Cheverolet in Wilmington NC. In April 2025 a recall was announced on our car for engine failure. In June of 2025 we received a letter stating that a fix for the recall was to have an inspection done. If passed, then an oil change and new cap would be done. This was completed. on [XXX], I was on the highway accelerating to get up the speed, when I heard a loud pop noise. Then i heard loud knocking coming from my engine, the check engine light came on with the traction light as well. The car then had sluggish acceleration and would not accelerate but would have high than normal RPMS and rev when trying to accelerate. I knew then that I had engine failure. I was able to get the car to a safe place and called the dealership right away. They got it towed to Marine Chevy since it was closer. The next day they did an inspection on the vehicle and said the camshaft and lifters were broken and had to be replaced. I said I would need a new engine replaced due to the damage and recall. I was told it would not be under recall because it was the top and not bottom. They said the GM refused the new engine but would not tell me if it was the General Manager or General Motors that refused. I called and texted multiple times asking for pictures. They refused to send me any until 9/9 after multiple attempts. They only sent me one of the rods and rocker arms showing a rod bent and stated it was the lifters. still no pictures of the camshaft broke or lifters. These problems already have multiple class action lawsuits out for this particular engine failure. I was told the recall would still be on the engine even after the repair, I can still have engine failure. I refuse to pay the money for this car to continue to be in the shop due to a bad engine that was put in these models. I also have a case open with General Motors for replacing the engine as well and they are refusing to help. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  When i asked Kunez Lake Geneva, Wi. When the engine recall would be taken care of. I was told that GMC has to order the recall first. Then when asking about the process of inspecting. They informed me they would listen to the motor and decide if it was effected or not. I paid $82k for this vehicle. I find that listening to the motor isnt a thorough way of inspection. After they deem the motor ok. There going to put higher viscosity oil & an oil cap. What if something happens in the future. Is my familys life safety not important? Summary General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2021 – 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, and GMC Sierra 1500, Yukon, and Yukon XL vehicles equipped with the 6.2L V8 gas engine (RPO L87). The connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects that can lead to engine damage and engine failure. Safety Risk If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. Remedy Dealers will inspect and, as necessary, replace the engine. Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner’s manual insert.

  I purchased a brand-new 2023 Chevrolet Tahoe. One of the key reasons for choosing this vehicle was its built-in safety and connectivity features, including the OnStar system. I also pay more than $50/month for an OnStar subscription, trusting that the service would provide essential safety functionality. Recently, the OnStar system in my vehicle stopped working. I received no warning, no service bulletin, and no notice from GM or OnStar of thhe failure or that this was a known issue. Upon diagnosis, I was informed that the OnStar module had failed and would need to be replaced—at a cost of $822 out of pocket. OnStar is a core safety feature that GM actively promotes as part of the vehicle’s value and security. For such a critical system to fail in a vehicle that is barely two years old is unacceptable. I believe this constitutes a product defect that GM/OnStar should be held accountable for, especially since multiple consumers are reporting similar issues on public forums. Most of all I had no indication in the vehicle of the failure; there was no check engine or issue light indicating a failure. When I called onstar the only explanation I got was that I should have noticed that the onstar light was out. That’s not sufficient for a safety item you expect to work like the breaks.

  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.

  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.

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.

  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)
