Backstory: We purchased the van in April of 2021 and drove it a lot for two months with 0 issues
We made a cross country trip from AZ to GA to see family. When we got to TX there was a heavy downpour and tough storms. We started seeing issues here and all sorts of error codes popped up. 20-25 codes came up on scanner and our dashboard was lit up. Van went into limp mode on several occasions (very dangerous!) and intermittently would not start. We limped back to GA eventually and dried the van out and it worked for a week. Checked it at a Dodge dealership and they could not find any issues. We proceeded with our journey with small issues here in there with electrical which we originally thought was water related (and still could be)
We made it into South Dakota with 0 issues and started our adventure. We had one issue where it didn’t start and went into limp mode, again, after it had rained. We brought it to another dealership and they could not figure it out. We brought it to an independent mechanic who jiggled around some wires and eventually had it good enough to run where we felt safe then cleared our codes. We drove for a couple weeks no problem.
Got into Wyoming and did not have any issues. Spent a couple weeks in a few towns but had a severe issue outside of Sheridan WY and had to make an emergency pull over and we tried to troubleshoot it ourselves. I reconnected wires, reset battery, dried out different components and it worked! We kept on our drive to visit areas in WY then made our way to our destinations in Montana next. No issues for a week or so in Montana. Drove through Billings-Bozeman-Butte-Missoula no problems. In Missoula we had a delay, again after it had rained, and after i did the same old trusty steps of jiggling some wires and letting it rest we drove right on ahead.
We were heading to Kalispell when disaster struck us in a small town of Polson MT. Worst trouble yet and most errors. Stalled out at a red light and barely limped out of traffic into an autozone. Stranded for two days after working on it tiredly ourselves, we called a tow to get it to a local mechanic. Mechanic took a week and didn’t find any thing wrong with connectors, battery or wiring. Van was fine for about 4 days then disaster all over again. Had so few places to stay we were stranded again. We had to call another tow and reluctantly got it towed back to Missoula at their Dodge dealership there. This has been a month now since being stranded and had a very difficult time finding places to stay without going broke. We are flying out of here tomorrow to stay with some family to just reset everything.
Dealership has had it over a week now and they aren’t 100% sure of the issue. They replaced the ECM because they thought that was the issue, check every wiring harness and connector point and found no issues. We are running out of ideas and are very worried we will have to list it as a total loss.
Sorry for the long story but we are in a desperate situation since our whole life is in the van and we are with our dog. No many resources left or choices. If anyone has any advice it would be extremely helpful!
