I had just pulled off from street light, hit button to turn auto engine shutoff off, all of sudden I lose power as if I'm in neutral, engines reving up but won't go. Then kicks in but with less power like gears will not shift. I get to my destination but car will not go in reverse.

My vehicle started making a weird noise and when I took it to the shop, they told me my crankshaft has gone bad and I was lucky I caught it before the entire engine blew

My 2021 GMC Yukon suffered the same engine failure that is the subject of the recall. It has just over 70,000 miles. I'm now told I need a new engine. The dealer confirmed that this is the same issue that has impacted other similar vintage Yukons.

Oil consumption is an issue. My vehicle is using a quart of oil every 1,000 miles. Manufacturer says oil changes are 5,000 mile intervals, however at 2500 miles the dipstick is dry and the low oil light comes on. There are no leaks in the driveway, nor is it smoking. The manufacturer claims this is normal. If I were to wait the 5,000 miles for an oil change I would only have three quarts of o...

2 days after the delearship changed my oil to a heavier weight, my engine began knocking. I’m told the rod is bent but not covered by warranty

In 2024, while the vehicle was still under warranty, we brought it to our GM dealer due to an air suspension fault. The problem typically occurs in extreme cold weather, and following that visit, we did not experience further issues during the remainder of that winter as it was never that cold again. However, the following winter the same issue returned and was diagnosed yet again, and this year w...

I had the 25v-274 recall serviced at my GM Dealer and was never provide with any paperwork on the extended warranty that was part of the recall. as you can image, not having anything in writing is a big risk as these engines have been catastrophically failing. GM was supposed to provide a extended warranty and service manual update.

The engine has started using large quantities of oil. Not dripping oil, burning oil. I have been doing oil consumption studies with GMC for months now. It burned 7 quarts in 5,000 miles. The dealership tells me it is not part of the current recall on others with the same engine, make and model. It is doing the same thing as what the recall is for and my VIN number should be added to GMC’s recall l...
