| Engine And Engine Cooling problems |
On Saturday, April 25, 2026, I experienced engine failure on my 2024 Chevrolet Tahoe 6. 2l v8. This was a very dangerous situation, and could of been potentially dangerous to others around me on the highway. There was no warning just complete loss of engine propulsion at highway speeds. It was towed to the dealership on this same date. On Monday, April 27, 2026, it was confirmed by the Chevrolet dealership that this vehicle suffered catastrophic engine failure and that the engine was seized up. Inspection would be available upon request.
The contact owns a 2024 Chevrolet Tahoe. The contact stated that while driving at 76 mph, the vehicle was driving abnormally rough. The rpm increased, and the message to shut-off engine and restart the vehicle was displayed. The contact stated that the failure occurred while the two minor children and their friends were inside the vehicle. The contact's daughter stated that the vehicle was in neutral after leaving the car wash. In addition, the failure occurred while driving on a busy two-lane highway. The vehicle was almost involved in a crash twice when the engine seized in the middle of the left lane. The contact stated that while attempting to drive the vehicle to the shoulder of the road, the engine seized. The contact stated that while attempting to start the vehicle, the vehicle failed to restart. The local police assisted with traffic control. The vehicle was towed to the dealer; however, the failure was not duplicated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The dealer was informed that the mobile app indicated a transmission and engine failure. The dealer informed the contact that because the engine seized, the engine needed to be replaced. The dealer informed the contact that there was no indication of what caused the engine to seize. The manufacturer was made aware of the failure but provided no assistance. The contact referenced an unknown recall with a similar description; however, the VIN was not associated with the unknown recall. The contact was advised to contact the NHTSA hotline to report the failure. The failure mileage was approximately 16,988.
Dealer checked the 6. 2l motor for known defects. It "passed" inspection on 11/20/25 and got the thicker oil (ow-40). The engine lost propulsion ("died") 3 times on a 55mph state highway on 02/09/26 with my 4 year old in the car with me. It died and came to a complete stop in one lane and would not re-start initially with cars almost rear ending us and needing to aggressively swerve to avoid hitting us. After 4 or 5 attempts it started again (making terrible grinding noises) so I could get it off the road before it died again. It started again to drive home on the back roads approximately 1 mile. Low oil pressure and check engine lights came on. I also received notifications from onstar and from the my chevy app that there were severe motor or transmission problems. I scanned it with an obd ii scanner and it has code p00016 (camshaft position correlation - bank 1 sensor a). It got towed to the dealer and is now confirmed it is in need of a full motor replacement less than 3 months after they told me the motor passed inspection! this is not acceptable. To be told it's fine and then have it fail with my child in the car is extremely unsafe. Now I'm stuck trying to get a comparable loaner vehicle from the dealer to drive in the snow and mountains with my family safely while they expect to have the vehicle at minimum of 6 weeks. So far they have not found a loaner potentially putting my family in further danger by not having a 4x4 vehicle in a snowy climate.
Driving on the new jersey turpike I passed through the ez pass tolls traveling west bound on bayview Ave bridge, the vehicle shut off without warning. No check engine light or noise, just no propulsion or anything. Dead in the water. Vehicle would not restart.
The contact owns a 2024 Chevrolet Tahoe. The contact stated that while driving approximately 55-60 mph, the vehicle stalled. No warning lights were illuminated. The vehicle was taken to the local dealer 10 times and the dealer retrieved diagnostic trouble codes for the control module, body control module, rear parking assistance, loss of communication, and transmission solenoid. The vehicle was not repaired. While driving at an undisclosed speed, the vehicle shifted out of the intended gear and shifted into neutral. The vehicle then went into limp mode. The manufacturer was contacted and opened a case. The failure mileage was approximately 30,837.
The contact owns a 2024 Chevrolet Tahoe. The contact stated that while driving approximately 35 mph, there was an abnormal knocking sound coming from the vehicle. The vehicle stalled, and the message to "press the start button” was displayed. The contact was able to restart and drive the vehicle. The contact stated that the following day, while driving and depressing the accelerator pedal, the vehicle hesitated before accelerating, with a rattling and tapping sound coming from the vehicle. The contact continued driving; however, the vehicle stalled with the message to “press start button” displayed. The contact attempted to restart the vehicle however, the check engine warning light illuminated. The vehicle was towed to a dealer, but was not diagnosed. The vehicle was not repaired. The contact stated that prior to the failure the contact experienced failures with the vehicle related to NHTSA campaign number: 25v274000 (engine and engine cooling). The contact had taken the vehicle to the same dealer approximately 3 months prior for the recall inspection. The dealer stated that the engine had passed the inspection, and an oil change to a higher viscosity oil was performed. The contact then noticed the abnormal engine ticking sound and became aware that the engine was not responsive while depressing the accelerator pedal following the inspection. Additionally, the engine was idling roughly. The dealer was contacted, but informed the contact that the engine had passed the inspection. The contact stated that the recall had been removed from the VIN and was listed as completed; however, the vehicle experienced engine failure and was currently at the dealer. The manufacturer was informed of the failure. The failure mileage was approximately 25,000.
Purchased new vehicle in September 2024, immediately after purchasing the vehicle the engine had a clanking noise. Took the car back to the dealership where they explained the noise was normal. The car continue to make clanking noise, but noise continued to get louder, took the vehicle back to the dealership for first oil change, verify the noise, and discuss safety recall received on the vehicle. Dealer told me the car was ok to drive. In October 2025, the vehicle loss power during acceleration with immediate re-start. After this incident, took the vehicle to another dealer where they inspected the vehicle again. The test failed and the car now needs a new engine. Car has now 10k miles in the odometer and has been sitting in the dealership for 3 weeks now waiting for an engine replacement.
See attached document for complaint. We are writing to express our concerns regarding ongoing and unresolved issues with our 2024 Chevrolet Tahoe high country deluxe package, which we purchased on [xxx] from titus-will Chevrolet in olympia, washington. Our vehicle was ordered on [xxx] and delivered with 12 miles on the odometer [xxx]. The total purchase price was $97,889. 61. This vehicle is equipped with a 6. 2-liter ecotec vb engine and a 10-speed automatic transmission. Since shortly after purchase, we have experienced intermittent audio output problems. With these problems, there is no audio for the radio, phone calls or mapping directions from any of the apps. Incoming phone calls do not connect and outgoing calls cannot be made. Despite multiple service visits-[xxx] as well as documented audio output issues my wife recorded and dated due to the fact that the dealership is 50 miles away: [xxx] we have also driven our vehicle into the titus will dealership service department twice when the audio output was not working so the service techs were able to see exactly what was not working-the issues are still unresolved even after updates from the service department and over the air updates that were to "fix" the issues per GMC/Chevrolet. Our dealership has been unable to identify or correct the defect. Additionally, we received a safety recall notice (n252494000) on may 20, 2025, concerning a potential loss of propulsion in the 6. 2-liter engine, which may lead to catastrophic engine failure and increased risk of a crash or harm. We were surprised to learn that this recall was issued on April 24, 2025-prior to our purchase date-yet was not disclosed by the dealer at the time of sale, which also appears to be deceitful on GMC's part. We would not have accepted the vehicle knowing there were catastrophic engine problems as we travel the highways often visiting family in idaho and spokane as well as taking care of our elderly parents this last year with their medical care transports. When we contacted titus-will chevr.
On October 23 I was driving my vehicle and the airbag light and a message service safety restraint appeared. On October 24 I was in route to take the vehicle to the dealership and as I was merging going to the highway the vehicle turned off, lost complete power threw itself into neutral. I had to drive it over to the shoulder to keep from getting hit. I was able to get the vehicle to turn back on and got it to the dealership. This would be the third time that the vehicle has lost power and completely turned off while driving the first time I took it to the dealership. They said they couldn’t find anything wrong. The second time this happened. I took it to the dealership. They said they replaced the gateway module this third time I took it to the dealership they have called me and said they need to replace the onstar telecommunication module. The vehicle is unsafe. It is a brand new 2024 Tahoe I purchased it new. The vehicle should not be turning off while I’m driving the same messages consistently pop up the airbag in the service safety restraint. They replaced some kind of console at the top and say that that would fix the issue, but it didn’t because the message came back on again the vehicle idols as if it’s gonna turn off whenever I go to stop the vehicle the transmission stutters are like it’s going into a downshift and it acts like he wants to turn off, but it doesn’t it’s only turned off when I’m driving and then it will just shut off.
Low oil life notification on phone. Since l87 recall, an oil consumption test was stopped and the new type of oil has been added to the vehicle 5k miles ago. Had to add a full quart to register on dip stick. Will now start another oil consumption test with a dealership. I am very concerned about my families safety.
The vehicle in question had approximately 5000 miles when low oil light came on, it was 2 quarts low. This was after the first oil change at around 3500 miles. I had the dealer do an oil consumption evaluation. They check the oil every 500 miles and confirmed it was using 2 quarts every 2500 miles. They informed me gm says this is normal. I cannot disagree more with that claim. Gm knows they have a problem with the 6. 2-liter engine. I have researched the issue and found they have a problem with the crankshaft machining and the oil delivery port beveling that delivers lubrication to the connecting rod bearing appears to be too large that causes the motor oil not to consistently keep the bearing lubricated. This causes the engine to be an "oil burner" and premature failure of the bearing. They think putting a heavier viscosity of oil in will delay the inevitable engine failure, which makes me believe they are aware of the faulty manufacturing and want to run from their warranty responsibilities.

When driving on the highway at 75 mph, my vehicle alerted me to add oil. We immediately pulled off the side of the road checked the oil. There was not even a drop on the dip stick. Had to add 3 quarts of oil to even register on the very tip of the dip stick. Please note we were within 100 miles of being due for an oil change. The vehicle is currently at a chevy dealership to start the process of inspection and do an oil consumption test. This vehicle is my main transportation to take my children to and from school and activities. We live in larkspur, our children go to school in monument and we have sports in castle rock, so we drive quite a bit. I’m not sure that I’m comfortable with a small fix and using a different type of oil to see if my engine will be salvageable. My questions: can you confidently let me leave your dealership and guarantee that my family will be safe and know that my engine will not fail due to the recall issues? if my car engine needs to be rebuilt or replaced do you have a comparable loner car until then? if my car engine needs to be rebuilt or replaced can you confidently say this is not going to affect my resale or trade in value? do you have a recall trade in credit for a 2025 vehicle? I spent $85k on what I thought was a reliable vehicle for me to drive my 2 children around in. My biggest concern is that my engine stops running while I’m on the highway at a fast speed with or without my family. If my husband wasn’t in my car when the oil notification came on, we probably would have lost our engine. How is gm going to make this right and guarantee safety for my family? how is gm going to help with our frustration, anxiety and loss of time dealing with this mistake of selling vehicles with a defective engine? when will I have these answers?.

My family and I were returning from vacation from florida to our home state, north carolina, when our new Tahoe with 5700 miles started to act strangely. We hit bad traffic leaving florida so there was plenty of stop and go type maneuvers. At one point, the vehicle turned itself off and put itself in neutral while we were thankfully going a slower speed due to traffic. I was able to get off the shoulder near the [xxx] and restart the car. It ran fine after restart until it started making a clanging type noise from the engine bay. We stopped again and checked temperatures and fluids and the clanging stopped. About 30 minutes later the clanging and a guttural noise began to occur from the engine bay and the transmission would not shift, keeping the vehicle at/around 4,000 rpm at 60mph. We were able to get the vehicle to a nearby rest stop. My wife, 3 children, and I were put in harm’s way due to gm’s faulty product and poor quality control. To have your vehicle shut itself off and/or not shift, especially on the interstate, is incredibly dangerous to the occupants of the vehicle as well as the motoring public. It is important to note that the vehicle never displayed any warning lights of any kind before, during, or after the incidents described. Almost two weeks later, Chevrolet (cooper Chevrolet s. C. ) has not even diagnosed the vehicle. They have told be that they will more than likely have to tear the motor apart to figure out the issue(s), confirming that the problem has been replicated by their technicians. The Tahoe is equipped with a 6. 2l v8, a motor with well documented issues. The Tahoe is currently located at cooper Chevrolet in walterboro north carolina. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
I was driving on the interstate, when the vehicle went into neutral and I could not put it in the drive. I coasted over to the side of the road and then could not get the car out of park at that point. It was towed to the dealership, and I have been told that it has engine failure and needs a new engine.
On one morning w/20 something temperature, Tahoe started and immediately shut down. When restarted, multiple malfunction lights were lit: engine, abs/brake, steering column, traction control, etc. Reached onstar for advice to see if Tahoe was drive-able, but only got confirmation of system malfunctions and offered roadside assistance but declined since at home and would call back if needed. About an hour later and several restarts, all malfunction lights finally cleared except engine light, which stayed on for another day or so. Tahoe drove okay during engine light on.
[xxx], my chevy Tahoe engine sized up with a warning light no oil pressure and the engine turned off. I was left stranded on [xxx] with no cell phone service and no onstar. Good thing I had my sxs. I was able to travel to work at the mine site where I work and was able to get cellphone service. I called my wife and she contacted the dealership and they sent out a tow truck from richfield, utah. The dealership said that I will have to pay the tow bill that’s is around $900. 00 dollars. And my wife asked about a loaned vehicle and the dealership said that they don’t have any loaners. The dealership called me about three days later and said that the engine had spun three connecting rods. The dealership said it would be two months before they could get a new engine and in the meantime I’m still making payments and I bought the truck for work and I’m left using my wife’s car. When I started doing research I was amazed that Chevrolet has known about this issue with their engines and have not issued a recall. This problem has been going unresolved since 2005 and they just keep selling engines knowing that they will fail. My truck has 17,000 miles on it. The warranty is up at 36,000 miles, so the engine is covered under warranty. But l am left a foot and at their mercy. Very frustrating! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
