2021 CADILLAC ESCALADE Complaints
My vehicle died in the middle of an intersection, I was stranded in the intersection, I could not put it in neutral to move it out of the way. Luckily I was in town and not on the freeway. That is my issue. My cadi had to be dragged onto a tow truck bed and dropped at my local gm dealer in wabash. The reason it died was the fuel module. But not being able to move my vehicle out of the way is so very dangerous.;

2021 CHEVROLET SUBURBAN Complaints
This vehicle has been towed approximately 7 times in the last year. For all instances in [XXX] in 2025, the dealership told us there were no issues. The completed the recall on the L87 and it 'passed'. The dealership then updated the oil to 40W and sent us on our way. We continued to have issues, but it was deemed to be the transmission. We had that relaced earlier this year. On XXX the car shut off again while driving on a highway. Upon this dealership taking a look at it, they have determined the engine has locked up for reasons under the L87 recall. I wanted to note this with the NHTSA as the recall was completed, but later found that it was not actually corrected through their guidance within the recall.
