On Friday, [XXX], I took my 2026 Chevrolet Tahoe to Hilltop Chevy in Somersworth, NH for an oil change and tire rotation. The following day, [XXX], we were on our way home from Concord, NH and noticed smoke billowing out from the back of our vehicle. We pulled over to the side of the road where I noticed a large amount of oil coming from under the car. When getting back into the car, I noticed the Low Oil message on my dash. We immediately called the dealership, who gave us a tow truck number to call to come and pick up the vehicle. The safety of our kids, dog, and myself and wife were put at risk because by the time we had pulled over, the car was smoking badly and almost out of oil. It was confirmed by the dealer where they told us it was a recall, however, we discovered no recalls on any parts of our vehicle. It was an error on the technician who did the oil change the day before. That morning before we left the house, we noticed a large puddle under our car, but thought nothing of it. We now realize it was oil and has now stained our driveway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V‑274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V‑274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GMâs recall remedy for Recall 25V‑274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V‑274, 473 of which involved an oil viscosity change and 26 a complete engine replacement.

What 2026 Chevrolet Tahoe owners say
Most recent owner complaints, unedited.
Engine failures, dealers will not address the issue as related to 21 they 24 recalls
Vehicle accelerating on its own. It is not in cruise control mode. Accelerating without any pressure on the pedal. Engine revs when in park. Really jerky when coming to a stop
The contact owns a 2026 Chevrolet Tahoe. The contact stated that while his wife was driving 45 MPH, the brakes failed to engage while depressing the brake pedal. The contact's wife pulled into a parking lot, shut off the vehicle, and allowed the vehicle to coast in the parking lot until the vehicle came to a complete stop. Due to the failure, the vehicle was towed to a dealer but was not diagnosed or repaired. The failure mileage was 4,873.
While driving the vehicle at highway speeds the vehicle starts to lurch or randomly lose power. Eventually, within a few minutes, the lurching gets worse and the check engine light starts flashing. In a GM vehicle, a flashing check engine light is critical engine failure. After pulling the vehicle to the side of the road, the check engine light stops flashing and stays on constantly. After about 10-15 minutes, the check engine light turns off completely. The GM dealership can read the history and says it's P0300 error code for General Engine Misfire in cylinder #6. GM warranty refuses to fix anything because the light isn't on when the car comes into the dealership. The car has been to two different dealerships, with both of them telling me it has the same error code. GM customer service told me without the check engine light being on when the vehicle is brought into the dealership, they would not be able to help me. This is being told to me even though everyone agrees that the check engine light has been on. I was told by GM to continue to drive the vehicle. It has been into the shop 4 times since January for the same issue. This is not safe as the engine has suffered a critical issue. I don't feel safe driving the vehicle. My GM Customer Service case is 110460594.
At approximately 4,200 miles, the engine on my 2026 Chevrolet Tahoe High Country equipped with the 6.2L V8 suddenly shut off while the vehicle was stopped at a traffic light. There were no warning lights, messages, unusual noises, or other symptoms prior to the failure. The vehicle would not restart and had to be towed to an authorized Chevrolet dealership. The dealership initially suspected a camshaft/lifter or related engine issue and performed diagnostic and mechanical testing. The dealer also opened a case with General Motors. GM subsequently directed the dealership to perform an ECM software update. After the update, the engine started and the vehicle appeared to operate normally. As part of the dealer's post-repair testing, a dealership employee drove the vehicle to confirm the issue was resolved. After approximately 7–10 miles, the vehicle suffered another engine failure while being driven and again became inoperable. The problem was therefore reproduced and confirmed by the Chevrolet dealership. Following the second failure, GM authorized replacement of the complete engine. The dealership has received a brand-new replacement engine and is replacing the engine and radiator. The original engine/component is currently at the dealership and may be available for inspection. I consider this a serious safety concern because the engine failed without warning while the vehicle was in use. Had the initial failure occurred while traveling at highway speed or in heavy traffic rather than while stopped at a traffic light, the sudden loss of engine power could have created a significant risk of a collision. The vehicle is a 2026 model with approximately 4,200 miles. I am reporting this because of the extremely low mileage at which the engine failed, the absence of any warning before the failure, and the fact that the vehicle failed a second time shortly after GM's initial attempted remedy.
Driving on the interstate and vehicle started slowing down then abruptly stopped. We were able to get onto the shoulder of the road. The gear would not stay in drive mode continuing to slip out of drive and into park. We made it to a dealership in Knoxville tn where we had to leave it..
Engine started "ticking" for a bit. Then sounded like marbles were in the engine. Loss of power and engine light came on. Dealer says my 6.2 engine failed and new one needed. Less than 9000 well cared for miles!
Driving on the Highway the Engine failed at highway speeds and the Tahoe experienced a complete shutdown, we could not restart the vehicle nor shift to neutral. We had the vehicle towed and was told by the dealer that it needs a engine replacement at 14,000 miles.
The contact owns a 2026 Chevrolet Tahoe. The contact stated that two hours after parking the vehicle in the garage and turning off the vehicle, there was excessive heat coming from the vehicle, and the vehicle was extremely hot to the touch above the wheel well. Due to the heat coming from the vehicle, the contact stated that it was difficult to breathe while inside the garage. The vehicle was taken to the local dealer, but no failure was found with the vehicle. Later, while driving the vehicle, the vehicle lost power, and the check engine warning light was illuminated. The vehicle was driven back to the nearby dealer and was diagnosed with a fuel pump module and fuel pump hose failure. The contact was informed that the parts needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 129.
