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.

The component that is failing is unknown. Unknown to mechanics because a code is not thrown. I can be driving in my neighborhood, on the highway or coasting and my Jeep stalls. Everything else is working, radio, heater just the rpm goes to zero. I have to quick turn on my hazards and prey I can coast to safety. Once out of traffics way and I am in park my car will restart no problem. my safety is at risk because it will happen on the highway. My mechanic has checked all the sensors, fuel pump and filter, battery cables, alternator you name it its been checked or replaced. I have read Jeep forums to see what others are saying and there are over 100 other jeeps that have this same problem. People are spending thousands of dollars to change out computers several times for it to keep happening and jeep has no answers. …
The ABS warning light, Traction Control warning light, and Emergency Brake light are all lite up on the dashboard of my 2015 Jeep Wrangler Unlimited Sport. ABS is not working on my Jeep. Mechanic shop checked for codes and said the ABS control module is bad and needs to be replaced. The shop qouted me $1,500.00 for parts and labor and that was if they could find a new ABS control module somewhere. If part isn't replaced, I'm told that brakes could fail or Jeep could seize up after being driven so many miles. Mechanic shop said ABS control module for Jeeps is on National backorder and they are hard to find, can find used ones at salvage yards but they are priced three and four times what they normally cost brand new and they may or may not be able to flash the module to match my VIN on a used one. …
Our 2015 Jeep Wrangler JK Unlimited just caught on fire. I happened to be in my daughter's bedroom, 20 feet away from where the Jeep was parked. I thought I was seeing flames reflecting from the TV, but I realized that they were real. My next thought was that my husband was building a firepit fire. I thought that was weird because he was doing it in the front yard, but I didn't think any more about it because I was so focused on my work. I went back to work for a second, but something told me to look again. I did, and then realized that it was the Jeep that was on fire. I screamed for my husband, but couldn't find him; I was scared that he was in the Jeep. Actually, he had been in the back yard and heard me screaming, so he ran up front to see what was happening. …
