What owners wrote

“The doors, hinges, hood and other places is rusted, bubbled and huge 1-2" pieces of paint are coming off the 2018 Jeep JL Rubicon Unlimited at 32-35k miles. This is absolutely unacceptable when my unrestored 1988 Jeep Comanche is rust free! Been to every dealership around and they confirm it's an issue with these, but refuse to fix.”

“Paint, bubbling and corrosion not declared as a defect by the jeep dealership. I would have never purchased knowing this information. I am looking for a goodwill repair of the defect of mixed metal causing corrosion on the body. Jeep states I am out of the extended warranty for repair. I am hoping to open a claim to get a repair of this manufacturing defect that was not disclosed in good faith to me.”

“There is paint bubbling on all 4 doors near the hinges and bottom of the door, as well as the hood of the vehicle.”

Should you keep driving it?

This page can't tell you that. 0 of 40 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
