There are 2 owner-reported fuel system complaints for the 2021 Jeep Renegadein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The fuel line was rubbing against another pipe between the engine and firewall, causing it to leak, spraying gas all over the engine including the exhaust. In my opinion if this hadn’t happened in traffic where you could smell it but on the interstate I hate to think what may have happened. I’ve looked on the jeep renegade forums and there seems to be other people who have experienced the same problem. The fuel line was replaced at 47000 and I’m wondering if I should expect the same thing to happen at around 94000 miles.
Fuel line bundle - dealership said its corroded it’s only a 2021 with no prior damage.
