I had a 2015 2 dr Jeep Wrangler willy's edition. In March 2023, after sitting cold in the driveway for 10+ hours, it spontaneously combusted. It was very obviously an electrical fire based on the smell alone. It appeared that the most damage was in the area of the battery and fuse box. Vehicle was completely totaled and I found many reports online of similar issues, including many Wranglers that were completely totaled after the fire. There is no official acknowledgement of this recurring issue. The fire caught so fast, if I had not been parked in the driveway faced away from the house, I might not have a home either. Insurance did not do an investigation into the cause of the fire.

My truck was making a loud clicking noise and kind or rattle. I took the vehicle in to be serviced. I was told that I needed to have all lifters, rockers and cams replaced. That these items being worn out is a known issue with Jeep Wranglers but there has not been a recall for this issue. The dealership replaced those items the camshaft exhaust, camshaft intake, arm valve, tappet valve lash, gasket cylinder and gasket intake. As stated by the dealership having to replace the lifters, rockers and cams is a known issue. Most people just trade the truck in. I would like to know if this is a known issue why has there not been a recall for this? also because of the cams this caused the cylinder misfire in the engine.

My vehicle has been suddenly shutting off while I am driving. There is no warning that anything is wrong with the vehicle. The first time it happened was October 2021.

64 Engine And Engine Cooling problem

Failure Date: 08/24/2018

While checking my fluid levels, I noticed oil in the vicinity of my oil filter and in the valley. With little search, it was apparent, I had a poorly designed oil filter/cooler adapter. Took it to the dealership and again, to my surprise, they did not honor the manufactures warranty but of course charged me 160 bucks to tell me what I originally told them. I then asked if they had the part available, guess what they said?? of course, they don't have any due to national backorder. Mind you, my Jeep has only been dealership touched and at 35000 miles, this should not be an issue. I am forced to drive my other vehicle due to fear of my engine bay igniting, as you and I both know it has sadly happened to many others.
