After a light rain I noticed water dripping into the passenger side kick plate/glove box area. Car would not start. Had it towed to dealer. Started next day and could not replicate problem. Next day, same problem. Water noticeable in passenger compartment. Shook Smart junction box and notice water leaking out. Car started and stopped when sjb shaken. Took to dealer. Replaced sjb for $750. Month later same issue, this time car shut off while driving on freeway in rain. Loss of all control, electrical and power. Could not restart. Pounded on sjb and eventually started. Got it back home. Now brakes lights, turn signal, headlights, a/c and display panel not operating. I am surprised that someone has not been killed yet. In trying to solve this issue, it appears that the internet is fully of the same stories. Sickening.

New car , failed to start numerous times, do not drive car every day as I commute, only drive on weekends. Try to start car after 1 1/2 weeks and had to jump start it . Called dealer and they said that because it has computer it will be constantly running and that is why it did not start. So after a few more times not starting I got a die hard battery, car has failed to start at least more than 3 times since. I hardly drive this car, purchased in 12/04 and it only has approx. 8000 miles. I should not have to worry about my car not starting after a few days of not driving. It has only been 5 days since I last drove and I have to jump it again. I am afraid to go anywhere with it. If I go away on vacation for 2wks , I have to worry about coming home to a car that will not start. I am taking to dealer to see what can be done.
