My daughter made an attempt to start the vehicle, one night after community theater rehearsal, to drive home and found the vehicle would not start and she heard random relays chattering throughout the vehicle, had the windshield wipers move, the instrument panel lights flickered on/off along with displaying error codes "no fuse" and "no bus". The fuel pump could be heard running, even with the key off and she said the van acted like it was possessed. Based on online information, I replaced the crankshaft position sensor, which was listed as a top culprit in the problem and that solved nothing. Further research indicated the tipm unit is most likely the cause and we found that her make/model of vehicle is part of a lawsuit for this problem.
The van for a few weeks would occasionally not start on the first attempt, it would crank, just not start. At first I thought I just didn't turn the key long enough to start, but in the beginning of October it started getting worse and I knew there was a problem. I took it to a mechanic on oct 7th and they couldn't duplicate the no start issue and couldn't find anything, so I was asked to bring it back when their mopar guy was back. We thought it was a fuel pump issue so we tried to run a cleaner through it, but after a few days it only go worse. On oct 19th I brought it back to the mechanic (still thinking it was a fuel pump issue) and they said the crank senor was not responding. They replaced that twice but it still wouldn't respond to the programming. Had to pay $150+ for the crank sensor. . . They finally said that I would need to bring it to the dealership because it most likely was the main computer and since that part would be covered under warranty they could replace it without any out of pocket. I brought it to the dealership and they informed me it was the tipm and that it would cost over $1,000 to fix. The guy at the dealership said it's "not a common problem" so they couldn't get the part from their warehouse, they had to order it from the manufacturer and it would be in at the beginning of next week (oct 26th or 27th). I hadn't heard anything so I went into find out what was going on and he informed me that the part had to be made because "it's not common" and would hopefully be in around Friday (oct 30th). Still no word. And today I found out this is not uncommon that there is actually a class action lawsuit for this very issue!!!! they will not give me a loaner and I have 3 kids that I have no way of getting around in a little kia forte.
