2026 Jeep Wrangler Fuel system Problems

“On Friday, July 10 at about 5 PM I was parking in front of one of my favorite restaurants in my new Jeep Wrangler. When shifting going to complete.the park job the gear shift locked the engine began revving and the vehicle lurched forward. I applied the brakes got push back the tevving increased the vehicle lurched forward again. I re applied the brakes the revving increased the shift was locked and I lurched forward impacting the rear of the car in front of me parked. The throttle then released I was able to shift to park the revving stopped.”

“Vehicle has a bad stumble/misfire under light load around 19 mph and 40 mph the vehicle lunges forward.After being at the dealership for over a month, They say it is normal operation that all their vehicles 3.6L.Being a mechanic for 30 years this is not normal operating conditions. I have researched this online as many Jeep owners complain about the same problem.”

“Jeep purchased new on 28 January 2026. Fuel gauge only goes to 7/8 full after tank is full. Took it to dealer, they replaced gas tank, then 2 weeks later fuel pump twice, and fuel sensor unit. This solved the problem for 32 days now it’s doing the same thing. Took it back to dealership, they stated there was nothing they could do and engineering is aware and working on a fix. Called another Jeep service they said they weren’t aware of any updates or recalls.”
