Yestreday afternoon out of nowhere my dash started to show FCW system failed and the the engine light and LDW light came on. Headed home husband inspected the whole car and diconnected battery then reconnected. All warning lights and codes disappeared. This morning was out driving and still no warnings appeared, then this afternoon I had to drive to the library and when I turned on the car same thing happened with the warnings and fail codes popping up, but before the failure code popped up this time I got the code A13, which is oil change, rotate tires and replace transmission fluid. Could there be a a connection with the FCW failed and A13 code? I plan to take it to Jiffy Lube tomorrow to get the oil and transmission fluid taken care of. We have a 6 hour drive on Saturday to pick up our son from camp and I am so worried about something happening with the van.
