2020 Jeep

[tLOVE_]

Hello!!
It’s a long shot, but I wanted to see if anyone else has gone through the nightmare that I’ve gone through with my Jeep. I have a 2020 Jeep Wrangler sport, with a little over 100,000 miles. What started out as what seemed as simple as needing a new battery turned into a full engine replacement, and needing to get my fuse block changed 2x. Has anyone had an experience where they’ve had their original fuse block replaced with a Dorman, and having continued issues with the electrical system or eventually needing a full engine replacement?

no. a fuse cannot cause an engine failure. and when it comes to the fuse setup always got with the oem. 65-75 bucks..

what motor do you have. and what is the shop saying is wrong with the motor?

Hello,

It started as an issue with my battery not staying charged, the shop replaced several things before landing on the fuse block and when they replaced it, the put a Dorman in it. After that, I suddenly was leaking antifreeze & ended up having to take it to a certified dealer who told me that I needed a new engine. Fast forward the issue of my battery came back & I took it to the dealership this time, and they discovered the fuse block wasn’t OEM & was the reason the electrical system keeps failing

Sounds like your biggest issue is an incompetent shop.

Unless the plastic is melted on the PDC/fuse block, it will almost always be the high amp N1-N7 fuse array.

Agreed, and it’s costed me alot of money. I’m just trying to figure out if they’re the reason that I needed to replace my engine so that I can take the appropriate actions

I had the short block replaced in an older Wrangler, but that issue was wholly mechanical. That is to say, it had nothing to do with any part of the vehicle's electrical system, to include the fuse box, etc. I concur with the Final Cowpoke that the shop with whom you've been dealing isn't up to snuff, unfortunately.

Document everything you've been through, and assemble it (to include invoices, notes from phone calls, photos, etc.) in a binder. Having a single resource to refer to, and/or share with relevant individuals, will make it easier to keep track of the resolution process. Good luck.

I can't think of any electrical reason that would require an engine replacement. That shop already used an aftermarket PDC, and installed it incorrectly. It's not a difficult job, at all. If they managed to fry the throttle body, that would also not be a difficult job. Instead of having it fixed at Billy Bobs Tires-n-Things, have it taken to a local ASE certified independent shop in your area, that has very high ratings.

The dealer will only remove and replace parts based on a code, and an ability to recreate the issue. A dealer will always want to remove aftermarket parts and replace with OEM parts. In many cases OEM parts are best, but some aftermarket parts are as good, maybe sometimes better. I doubt the Dorman PDC itself failed. More likely, the guy who installed it bent a few pins doing so, and now the areas affected by the bent pins wont function.

I'm guessing that you don't have the skill level to pull it, diagnose the bent pins, straighten them, and reinstall it. However, it isn't all that difficult, just tedious. Have the shop doing the work start there. Again, the dealer will want to just install an OEM one, they will not try to fix the aftermarket one.

A new PDC, with fuses and the high amp fuse array is about $600-700 through the dealer. They will likely charge you $150 for diagnostics, and 2 or 3 hours of shop labor at about $200 hr, so expect that to cost about $1500. They may try to make it sound more serious and scary, trying to jack the price some more.

Either repaired, or replaced, along with a new high amp fuse array, I would bet all your problems will go away. Unless, there is actual mechanical damage in your engine.

Seems you're getting taken to the cleaners by what little info you've provided.

Only way something electronic could cause an engine failure would be if an injector was staying open and filled a cylinder with fuel. And it hydro locked and bent a rod. But you state the dealer said it was a coolant issue which would lead me to believe the head gasket blew. What motor do you have? There has been a few cases with head gasket failure and countless more with the oil filter housing seal leaking coolant into the engine. They have since updated that issue in the newer models but I don’t remember what year the changes happen.
