I've been having sporadic flickering low beam issues with this car since I bought it, and have spent untold hours and time trying to figure it out including taking it to the dealer. (I work nights. ) last week the low beams failed on the way home from work at midnight. Researched it, and finally saw the recall for gms and subsequently an ap story about widening the recall that was dated April 29. (I work at a newspaper and saw the wire story). I bought and replaced the module myself last week, and things are working well now and seem to be fixed. However, the dealer informs me that this car has not been included in the gm recall for failing headlight modules, so I can not get my money back for the module. This make and year model should be added to the recall. Please be aware that other models and years than have been recently recalled, are having this issue. It truly is a safety issue and up until last week, I was always wondering when my headlights would fail. Not a nice feeling when you work nights.
I tried to get my car inspected today in virginia but it failed due to the dummy lights on in the dash board abs and brake. The dealer could not comm with comp but changed the fuse for the cig lighter then the codes read ebcm module fault. . In 2014 my running headlights would just go out. . No lights until I put on high beams I have had them worked on and changed but still burn out.
