Re: 2012 Grand Cherokee starting problem
My 2012 Overland started having this problem on Sunday before Christmas when we were on our way out of town for the holidays. It would just crank but no fire. We were able to get to start reliably with the remote start option until yesterday when my wife tried to go run some errands and couldn't get it to start at all. After work I was able it started on the first crank so I took it to the dealership and left it overnight. I went over at lunch today and they told me they couldn't get it to start at all and theTIPM was bad. They are going to replace it under warranty thank goodness. (we rolled over 36k on our Christmas trip). The only bad thing is the part is back ordered but supposedly there are 150 in transit. They are hoping to have it in 3-5 days. Also called Jeep customer service and opened a case. They assigned a case manager and will try to expedite since our Jeep dead until it's replaced.
They did a recall for this on the 2011s but so far not on the 2012. The fuel pump relay in the TIPM is bad based on everything I've read. The p54 recall for the 2011 is a hacked in relay. I'm glad they went straight for the TIPM replacement in my case. Service manager told me they had a ton of issues with the TIPM across all platforms. Jeep is going to have to do something.
