2021 Jeep Wrangler: grinding or squealing brakes

Filed Sep 17, 2026 · Body · MA

I'm reaching out to complain about the corrosion issue on Jeep Wrangler JLs. I own a 2021 Wrangler JLU Sport with 56,000 miles and recently discovered the corrosion on my vehicle. I brought it in to my local dealer, who looked at the vehicle, explained the large issue they're seeing, and submitted a claim for my vehicle. I found I was just under 2 months outside the 5 year warranty. Stellantis came back with a good will offer of covering my cost 80/20. The total projected cost is $12,750 and I'm responsible for $2,550. This will replace my hood (with a steel hood), tailgate, all hinges, and repaint. After speaking with the dealer I've discovered they are no longer directed to replace the doors, but rather just grind them down. After reading and conversations with my local dealer's body shop, this isn't a fix, as the corrosion can still exist in the body. I opened a Jeep Cares case immediately after and explained I've owned multiple Wranglers since 2010, my father owns 2 Wranglers (a 2018 with this same issue), and I've spoken to other friends who own Wranglers and have this issue. They asked me to get a letter from my local dealership, which I did and provided. Jeep Cares came back with the same offer of 80/20. I've considered not paying this, but I'm seriously concerned that with my New England weather these body parts will become structurally damaged if I let this go. I'm also concerned about paying for the "fix" and having it come back shortly thereafter. I'd consider buying a new Wrangler, but the dealer explained the zinc piece they started adding isn't helping, and they are seeing new vehicles come on the lot with this same issue. Stellantis was aware of this issue considering they have a bulletin until a few years ago, but they've since removed that bulletin. They also never directed their dealers and service centers to notify clients of this issue. This is my largest complaint... they've known aboutthis and dn't let new/existing customers know.

Acceleration lag: either bucking or temporary loss of motive power when attempting to pull into traffic has almost caused us to be hit several times. We had the problem almost immediately after purchase, but the lag was short and the Jeep would leap forward and back tires would squeal which caused the back tires to wear quickly compared to front. The bucking and loss of power while accelerating became dangerous after I took to the dealership in Feb 2026 when they also did recall 68C related to the battery. We stopped charging it completely and still had the issue. Took back to the dealership in March 2026 and they said they could not replicate issue. Tried to schedule an appt last week and they never got back to me. We have avoided several accidents so far but I am now afraid to drive it. Assuming these are unrelated but just in case: at 10k miles the check engine light came on, and I couldn’t add ANY fuel (automatic shut off happened immediately) and the fuel cap wouldn’t open.

Vehicle will stop working in electrical mode...says "electrical mode unavailable" Dealership does NOTHING, vehicle performance is unpredictable. Sometimes will not start without a jump when the battery is fully charged from a 220 outlet. I've had it towed as I was stranded... dealership said "nothing wrong" ZERO diagnostic test to see if battery has a bad cell. Yet less than 24 hours from picking up at dealership, will only operate in gas mode. NOW it seems to down shift when I take my foot off gas....makes a grinding sound. Appears I purchased a lemon.

The engine has a manufacture machining defect causing the engine to lose oil. This component has been inspected my an authorized dealer and has spent 4 weeks in the service department trying to be repaired.

The dealership is an agreement this is a temporary fix to a larger problem of poor manufacturing by FCA suppliers.
