First the door lock on the left side would not lock; now it will not lock or unlock. The right side locks work after two of three pushes. The fobs quit working YEARS ago, and replacing the batteries did nothing to help the situation. Fortunately, I can still unlock the door on the driver's side with the key, and lock the doors the old-fashioned way-by pushing down all the door locks.
intermittues with cruise control and breaklights causes by poor electrical connections at the BCM
intermittently brake lights (stop lamps) do not function correctly; go on while driving without putting foot on brake; cruise either doesn't work, or when working, goes off without pushing any buttons.
REplaced all blubs in rear light panel and still the brake alight and blinker are not working.
My back break and turn signal lights will not work. The bulb itself works just fine, just not the function.
Poor Wire Connections, My brake light do not come on when i press down on the brake. HORRRIBLE
Alarm goes off for no reason after several hours with doors locked with keyless remote. Doesn't do it if doors are locked manually.
Emits a sparkling sound like, inside of the lower front passenger seat fuse box. Every time it does that the door lock system starts going on its own. Plus the alarm goes on once you had left the car untouched for a couple of Hours
Power door locks engage and disengage repeatedly on their own.
I also have trouble with the locks going in and out.One day my child went to the car to get her uniform and took to long so I went looking for her.She was screaming because the car had lock her in and couldn't get out.I found that when its a storm coming its worse so I don't leave anything in the car .
This has happened 2 pervious times and again just recently. before, I replaced the switch and the battery. worked fine after that. My brake lights would come on and go off when brake pedal was applied. Cruse control would not work either or word turn off while in use. Looked on line too see if there was a recall and on was put out march 2014.hope to get it fixed today.
