“My vehicle torque converter repair on my 2020 GMC Yukon is shuddering. Why is this not a recall when there are various Yukons that are experiencing shuddering related to torque converter repair. This should be a recall. The problem has been confirmed by a GMC dealer. There were not warning lamps, no messages, or other symptoms.”
NHTSA complaint #11739919, filed 2026-05“Hello, I’m calling about the GM transmission recall recently announced in March 2025 affecting 2020 Yukon vehicles. My Yukon experienced what I believe is the exact same issue described in the recall. Our vehicle lost forward gears and almost caused a crash. A certified mechanic confirmed the transmission fluid was burnt and full of clutch material, with internal transmission damage. We are asking for this to be handled under the recall, as the issue directly matches GM’s known safety defect. …”
NHTSA complaint #11650527, filed 2025-03“My vehicle went from driving perfectly to startling and not going pass 45 in a matter of two days. I was getting all maintenance done at dealer always on time had just service it. When all of a sudden it started making a jerking/ skipping feel as if I was accelerating too hard. Took it to get checked and the code that came up was (TCC)torque converter clutch. I spent 6000 to rebuild the transmission and kno the engine has a tap tap noise. Once again I took it in and now it’s the lifters in the engine. No warning light have ever popped up”
