2010 cadillac cts4 premium 3.6 wagon i replaced the rear prop shaft of the awd system in january 2018. i now am having issues with the rear prop shaft yet again, not 2 years later. i believe the driveshaft carrier bearing is failing again (same as before)! with approximately 49k miles on it. i cannot believe that i have to replace this same item again. after having to replace the rear differential twice on this vehicle, i now believe gm has no clue to make a reliable awd vehicle. worst car ever.
A drone noise at 55 mph.
Vehicle died while driving with no prior warning or error messages-complete engine failure, loss of power steering, brakes. unable to restart after several attempts. mechanic determined that the ecm had failed unexpectedly. when computer was replaced, they were unable to detect any sensor issues that may have contributed to ecm failure, they concluded that the ecm had failed while driving. had it failed on freeway, results could have been catastrophic.
The car shut off while driving down a hill this is the second time it has happened i checked with gm to see if there was a recall for this car and at this time there is not. we were lucky both times that there were no other vehicles around and that the car was kept under control while bringing it to a stop. although gm has no recalls for this car i am filling this complaint because of the many recalls that are out there for this same problem. will the third time be a charm when it happens and someone gets killed or seriously injured for gm to include this car? it will be to late!!!!!!! *tr
My car while driving on the highway has turned off out of nowhere while driving 60 mph while the car is still moving i put the car in neutral turn the ignition off n then back and the car turns right back on but some days this happens more then others. this problem has been going on for several months i have been in and out of the dealership. and they still to this day can't tell me what is the problem . but i have done research and there a lot of these incidents going on with gmc vehicles idk why they say they can't find problem or fix it . they just want me driving on the highway with my family when the car stalls out . this problem isn't everyday it seems to happen 3-5 times a month. i don't remember the exact dates but this problem has been going on since i got the car. if the dealer can't tell me what's wrong what am i suppose to. *tr
