At approximately 100,000 miles, repairs were performed involving the right-side cylinder head and camshaft because of camshaft/valvetrain wear and a persistent cylinder #2 misfire. The right-side cylinder head/camshaft…

   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…

    I am having my oil cooler housing replaced once again after having replaced only 4 years ago. I am on my 3rd radiatior and 3 thermostat. This jeep is not driven hard or offroad and has been maintained in excellent condition. This engine is junk and not safe. I have not had warning lights only oil drippings in the driveway yet the oil level doesnt seem to change. If not caught this will cause your engine to lock up.

    On a trip on 7/3/2025 out of state the engine failed due to a blown head gasket , which is the third engine related problem I have experienced . Other issues include: Broken exhaust valve spring, cracked oil filter housing. With being the original owner and having only 84,000 miles I feel this has to be an issue Jeep is having with my engine 3.6 Liter V6. I am lodging a formal complaint to hopefully, have help with the $11,000 quoted price to replace my engine. Thank you
