This is a follow-up to my previous complaint - 11716917. My second engine, which was installed after my first engine failed after approximately 5,000 miles, also failed. It failed after approximately 5,200 miles on it. I picked up the vehicle after the first engine replacement on 2/19/26 and the second engine failed on 5/18/26.
9 months into ownership, with 24,000 miles I had complete engine failure pulling into an intersection. Slamming into park while moving and shutting down. This is a known issue with the GM 6.2 liter engines but I specifically waited to order a 2026 as this was far outside the recall window GM had in place for this known issue and was led…
Unknown brought my car in on July 24, 2026. They reported they do not know what is wrong with the engine, but stated GM is not letting them take it apart and told them to replace the engine. While the car was parked and during acceleration, my car was making a weird noise that got louder during acceleration.
The contact owns a 2026 GMC Yukon. The contact stated that while driving 55 MPH and depressing the accelerator pedal, the vehicle failed to respond as intended. The contact pulled over to the side of the road, turned off and restarted the vehicle; however, the failure persisted. A dealer was contacted.
On July 30th 2026, I was Driving on the highway at about 75 miles per hour and the engine shut down. We were fortunate that we could pull over to the side of the highway. We had the truck towed to Oxendale gmc. Today 8/4/26 I was informed that in fact the engine needs to be replace.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre engine problems common on the 2026 GMC Yukon?
They are documented: NHTSA holds 53 owner complaints naming the engine on this model year (72% of everything owners filed about it), and 4 manufacturer bulletins, 1 NHTSA investigation are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the engine on the 2026 GMC Yukon?
No recall campaign is filed under this heading for this model year (there are 3 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do engine problems show up on the 2026 GMC Yukon?
Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.
What does NHTSA's "Engine" heading cover?
The engine and its cooling system. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
