“'takata recall' we just purchased our 2015 yukon dinali xl december 20, 2018 and have had nothing but problems with brake light ( while in motion ) on driver-side working intermittently, so we replaced both taillights with brand new ($700) enclosed rear light assembly and now we are having an issue with driver side once again. I'm very proud to buy american made products but after seeing how many Gmc monthly complaints with this same issue, you would think that GM would stand behind their product. …”
NHTSA complaint #11173848, filed 2019-02, 99,000 miles“At 75,000 miles I wouldn't expect to have this many issues out of such a nice expensive truck... The check engine lights comes on and off and it pleases. When the check engine light is on the remote start doesn't work. The tail lights work when they want to and to fix a tail light just 1 is $800.00. While driving all types of warnings and lights start coming on in a rapid warning annoyance. I've never hooked a trailer to this truck and it keeps giving me some type of trailer braking system warning. The cruise control works when it wants to. Big issue!!!!! The transmission is slipping!!!!!!!!!! …”
NHTSA complaint #11204356, filed 2019-04, 75,000 miles“I put in another complaint and forgot to add maybe the most important details!!!! I have noticed my cruise control, check engine light, brake lights, and remote start though I'm having issues with them all working only when they want to it seems when it's hot outside all of these things go hay wire and when it's freezing cold (colorado winter) everything works fine. Today high of 40 everything is working fine... Highs in the 80+ everything seems to not work. So it's basically boiling down to electrical issues when it's hot and no issues when it's freezing cold. Can someone please fix this!!!! …”
NHTSA complaint #11139221, filed 2018-10, 55,000 miles“While in motion my vehicle shuts completely off. This is in the middle of traffic at times. It displays warnings that stabilitrack has been disabled and shuits down everything electrical. At some points it doesnt shut completely down, but instead hesitates and then picks back up. This happens in various situations whether it be on the highway, turning, or driving city roads.”
NHTSA complaint #11074344, filed 2018-02, 50,000 miles“Faulty brake-light and costly fix. Dealership has taillight on back order so a replacement isnt even available. Dealership wants $675 just for the part that cant even be ordered. Dangerous to drive the vehicle with no solution available.”
