2023 Chevrolet Tahoe Engine Problems

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The oil was changed at the local dealer. After 24 hours, the engine was blown after driving approximately 50 miles. No warning lights were illuminated. While accelerating from a stoplight, there was an abnormal squealing noise from the drivebelt. The vehicle was taken back to the local dealer, and the contact was informed that the flywheel was hitting the camshaft and changing the oil had disturbed the function of the vehicle. The vehicle was not fully diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 14,945.

Passed a truck in 2023 Chevy Tahoe on a two lane highway and the Tahoe would not accelerate. It switched into neutral and would not run. This was a major safety issue. There was a semi truck behind me that could have run over me and my family. Luckily there was wide open area next to the road that I coast into. Truck was towed to a dealership out of state while we were on vacation.

My wife just picked up our 4 year old from daycare. She just merged onto I-81N and the vehicle shut off on her at highway speed during rush hour! A message on the dashboard said "Please restart vehicle". She managed to pull the Tahoe off onto the shoulder, but couldn't get it started. She remained in the vehicle with my daughter and called 911 to request a state police vehicle park behind her so that she wouldn't be hit by any passing traffic. I (her husband) met her on the side of the highway and we tried starting it with a battery booster pack to no avail. We called a tow truck and had the car towed to the dealership that we purchased the vehicle from. They confirmed that the motor was indeed locked up and needs to be replaced. This vehicle already underwent the 6.2L recall test and "PASSED". It was running the 'remedy' 0W-40 oil. This is COMPLETELY UNACCEPTABLE.

We were driving down the highway at around 77 miles per hour. I noticed that the vehicle chimed as though I initially got into it and needed to start the engine. I saw the dashboard asking me to start the engine. I attempted to start it while we were coasting to a stop, but it wouldn't start. I was able to barely get out of the lane of travel and avoid a collision. I tried to turn off the vehicle and turn it back on but it would not start. It would not even turn over. The vehicle eventually cannibalized the battery because it would never shut off.

1) The engine failed and lost propulsion while driving. It is currently at the dealership where I purchased the vehicle new, so it may be available for inspection upon request. 2) My safety was put at risk because the vehicle lost propulsion while driving. This is a dangerous situation in general. In my case I was able to pull over safely and have it towed to the dealership. 3) The problem is that the engine failed. This can be confirmed by the dealership. 4) This 6.2L engine was part of the N252494001 recall for specifically the issue of engine failure and loss of propulsion, so it had been inspected by the dealership recently. I brought the vehicle into the dealership for this recall several months ago. Per the recall, they told me that the engine would need to be replaced if it didn't pass the inspection. They performed a Pico test, informed me that it passed the test, and changed the oil to 0W-40. It has not been inspected by GM, the police, insurance representatives or others at this time. 5) There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Total Engine Failure

The vehicle motor goes out with no indication that anything’s going to happen. It does this a different stages of miles. Mine happened when I was passing someone on the high way. It just shut off

Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning and wouldn’t even start again. Warning light for low engine oil came on. We were stuck and couldn’t even put the vehicle in neutral to be towed out of the intersection. Had to call a flat bed tow truck to load it and take to dealership where it was confirmed the engine failed!!! Police did show up at the scene to facilitate traffic and the loading of th vehicle

I took my 2023 Chevy Tahoe in for all recall corrections promptly when the notices were received. My last recall was to run a check to see if my motor was one of the defective 6.2L engines. It was determined it was not and the dealer changed my oil to the new required 0w-40w. Now a month later as I am accelerating on to the freeway ,I am at 65 MPH I cross traffic to merge on to a connector bridge and my car RPM's go through the roof and the car starts to slowly lose power. Zero warning lights are on at this point just decreasing power. As I am on the bridge my engine light comes on with a engine oil hot idle engine notice I am now at 35 MPH. Then a oil pressure low turn vehicle off notice comes up and we are at 15 MPH the car turns off. The screen says press start again but as we do it wont do anything. It then randomly starts turning off and on. We got to a point on the bridge where we could coast to the connecting freeway below and pull over. My car was towed to the dealer where it has been confirmed it needs a new motor with no know ETA of the new motor.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling) in November 2025 by the local dealer. The contact stated that the engine had passed the inspection, and a higher viscosity oil had been added along with the other steps stated in the recall. The contact stated that while driving approximately 55 MPH, the accelerator pedal was depressed; however, the vehicle failed to respond. The gear shift indicator indicated that the transmission had been shifted into neutral(N). The contact attempted to shift to drive(D) when the vehicle stalled. The vehicle was stopped but was unable to restart the vehicle. The vehicle was towed to the same dealer who had completed the recall repair. The dealer diagnosed the vehicle and determined that the engine, starter, radiator, and fuse block needed to be replaced. The vehicle was being repaired. The manufacturer was informed of the failure and a complaint was filed. The failure mileage was approximately 48,000.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while her husband was driving at 70 MPH, the vehicle experienced a loss of automotive power. The check engine and "Oil Pressure Low" warning lights illuminated, and the vehicle unintendedly decelerated. The contact stated that while driving at various speeds, the message "Press START Button" was displayed, and restarting the vehicle temporarily fixed the issue. The contact stated that after further inspection, the contact became aware that the vehicle had independently shifted from neutral(N) to park(P). The vehicle was towed to a local dealer, where it was diagnosed; however, no cause for the failure was determined. The local dealer advised the contact that the oil level was possibly low, and an oil consumption test was needed. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign: 25V274000 (Engine and Engine Cooling); however, the VIN was no longer included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 33,253.

I purchased a 2023 Chevrolet Tahoe on December 17, 2025. On January 17, 2026, with approximately 17,000 miles, the vehicle experienced a catastrophic engine failure while I was driving. The engine seized without warning, causing a complete loss of power and leaving me stranded on the side of the road. At the time of the incident, my newborn child was in the vehicle, creating a serious safety risk. The vehicle had no prior warning lights or indicators before the failure. After the incident, I learned that there was a known recall or service update related to engine oil viscosity for this model year. This information was never disclosed to me at the time of purchase, and no recall documentation or corrective service was provided prior to delivery. I have since been informed that engine replacement will take over 30 days due to parts availability and that no loaner or rental vehicle is available during repairs. Given the catastrophic failure shortly after purchase, the undisclosed recall, extended repair time, and safety implications, I no longer feel the vehicle is safe or reliable.

Engine failure resulting in new engine.

On December 30, 2025, I was driving the Tahoe at a highway speed in Oklahoma City, Oklahoma. I experienced two engine shut-offs. I was able to get the Tahoe to the Chevrolet dealer in Midwest City, OK. Advisor Tim took care of the vehicle and said that they "couldn't replicate the problem." He did mention he had to add engine oil because it was a quart low. We noted that we are currently conducting an oil consumption test with a Chevrolet dealer in Elk Grove, Illinois. He said we had a strong case for it, but the Tahoe was safe for traveling back home to Illinois. The following days, the Tahoe performed well without any issues. On January 3, 2026, we left Spencer, OK, and headed back home to Illinois. Without any warning, while driving at highway speed, the engine shut off completely and would not restart. The failure occurred at approximately 9:00 pm on a pitch-black expressway about 40 miles from Rolla, Missouri. I was traveling with my wife and two children. We were stranded on the highway shoulder. A state trooper was dispatched for safety. The Tahoe required a tow over an hour later, and we had to take a Lyft to a hotel. Logistics at that time in that location were complicated. Our family was terrified for our safety. Today is Sunday, and the nearest dealer is closed. We will have it dropped off tomorrow, January 5th, and go from there. We do not know how we are going to get back to Illinois. We have work and my son has school. The vehicle is currently disabled and under manufacturer warranty. This was a serious safety incident involving loss of engine power at high speed.

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.

I dont believe the correct fix is changing Oil Viscocity

The idler pulley was squealing. Dealership I took it to said this was the 3rd one they've had to replace in the last few days.

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.

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.
