I have a 2018 AWD Chevy Trax. About a week ago I hit something on the road (no clue what) and blew 2 holes in my front driver-side tire, making it flat almost instantly. I let my car sit on the flat for the day while at work, and we changed it after work to the spare. On the way home, my car was driving a little crazy, Im thinking it was the AWD kicking on and off, since my car didn’t know what to do with the spare being there instead of a normal tire. The traction control light came on very briefly. We got the two holes patched, however, now I am having another problem and not sure if it might be related. Random times in the middle of driving, often when accelerating but not always, my back end will jolt. It almost feels as though I am running over a bump but only with my back tires. It also feels as though my back tire is getting stuck and not wanting to turn, it might be slipping? We weren’t sure what could be causing this, but it has only been happening since I hit something and my AWD kicked on and off so I feel like it has to be related somehow.
Does anyone know what might be causing this? Any help is appreciated.
Sounds like you need to get your speed sensors looked at. Maybe the sensor has gotten shifted or there is debris on it causing your AWD to do weird things. If it thinks your getting a lot of slippage on one wheel from a bad signal havoc will occur. You can do this yourself if you do some research on proper installation and testing. Brake clean will clean the sensor as well but on stands, safely with redundant precautions in place, with ability to rotate the wheel, to spray the ring, and removal of sensor for cleaning yields the best results. If that doesn’t fix it you may need to get it on a computer and see if the abc’s of the AWD are having issues. Good luck!
