2024 Jeep Grand Cherokee L Summit Reserve was parked before a snow / ice storm and when we went to drive it 5 days later, after the storm, it would not move and made a loud explosion noise when I pressed the accelerator.  I immediately turned the Jeep off and went to look underneath to see if I could see what happened.  The rear brake pads and calipers were blown off, along with a bunch of broken parts and the air ride suspension was at its fully extended height.  It's been to 2 Jeep dealers who can not explain what happened and Jeep says there is nothing they can do.  We have only owned this Jeep, which was purchased new, for less then 20 months when this happened.  If this had happened while driving, we could have had an accident and been severely injured.  The Jeep is available at this time to be inspected.  No  lights were on prior to this happening.

JEEP GRAND CHEROKEE L 2024 LANE DEPARTURE: BLIND SPOT DETECTION

I purchased my Jeep in 8/2024. Since purchasing this Jeep it has had an intermittent burning smell. I was told by the dealership I got it at that itâs normal for burning smells on new cars. Well 13,700 miles later itâs still doing it and a couple of times I have seen smoke coming from the hood area up closer to the windshield area.  I took my Jeep to another dealership on 11/29/2025. They drove it and smelled the burning but said they have checked everything and can not figure out where itâs coming from. They had me pick it up on 12/24/2025 and told me to bring it back if it did it again. On 12/26/2025 I returned the Jeep to the service department due to smelling the burning 3 times during the 3 days I had it. The service department still has my vehicle as of 1/12/2026 with no updates. I have contacted Stellantis and they have not done anything.    The date to the question of when this happened, I put in the last time it did it. The first time I do not recall exactly but I did contact the dealership in Feb 2025 to inform them my car smelled like it was going to catch on fire sitting at a stop light.

The contact stated that while driving at an undisclosed speed, there was an abnormal hissing and tapping sound coming from the engine compartment, with the check engine warning light illuminated. The vehicle was towed to a dealer, where it was diagnosed and determined that the wiring harness had failed due to rodent damage. The dealer informed the contact that the wiring insulation was soy-based and had been chewed on by rodents. The dealer stated that rodent urine and blood were found near the damaged wiring, and the area was not cleaned. The vehicle was not repaired. The contact was advised by the dealer to place mothballs under the vehicle to deter rodents. The dealer also confirmed that no protective covering or preventative measure would be installed to prevent a future failure. The contact expressed concern that the failure made the vehicle unsafe and stated that the contact was afraid to ride in the vehicle due to the issue. The manufacturer was made aware of the failure and referred the contact back to the dealer for further assistance. The approximate failure mileage was 3,332.
