My car is stock. Since 06/13 and in September of 2013 started to get warning light for TPMS of the left rear tire. Brought it back to dealer multiple times, but they could not duplicate the problem. In April of 2014 started getting "Service Stabilitrack code U0401 and Check Engine Light code P0300" warnings along with the TPMS warnings. The car has been in the dealer fourteen times and I gave them the above codes but four different dealers could not fix the car. After a lot of research I figured it was the ECM causing the problem, had it replaced in September 2015 and all of the warning lights stopped.
Drove it for around five months with no problem but then the TPMS started again and the dealer has no answers? I was told by someone that the Body Control Module and Powertrain Control Module connectors need to be replaced or there connections are loose?
have the same problem?
