Jeep Grand Cherokee fuel smell problems

Filed Sep 4, 2026 · OR

Exhaust system design defect. Original manifold system started to fail at approximately 40,000 miles, allowing CO gasses to enter vehicle cabin exposing passengers, including children, to potentially deadly exhaust fumes. Jeep, Jeep Service Centers have known since at least service bulletin 09-19-23 that the hangers and brackets used in the manifold system are not robust enough in design to “accommodate thermal expansion and engine movement without breaking or leaking.” I was never alerted to this. Addressing this via an unnoticed bulletin rather than a recall not only put me in physical danger, but ran out the clock so it could not be addressed as a warranty issue. Apparently, the manifold warps, gaskets fail, the vibration shears support bolts, and the carbon monoxide leaks into the car through the ventilation system upon warmup. Depending on severity perhaps the entire drive. Attached file is a $4200 estimate presented to me by the dealership where I originally purchased the car, preparing me for what I might have to pay out of pocket to fix the leaking exhaust system. There was no preemptive maintenance for this issue I could have had done, aside from not driving my car. Ever. I assumed when I bought the car that the manufacturer would not knowingly allow me to purchase a vehicle that pumps exhaust fumes directly into the cabin. I was wrong. This is a defect Jeep is obviously well aware of, and they chose to put their customer’s in harm’s way rather than taking action.

Exhaust small in cabin. Exhaust manifolds leaking pulling exhaust into the cabin through the climate system. When the recirculation is turned on, then the smell is not present. When the recirculation is off then the exhaust smell is strong inside the cabin. The exhaust in the cabin is causing causing respiratory problems, fatigue, eye irritation and I am concerned of passing out when driving. I frequently have to turn on the recirculation button to keep the exhaust out of the cabin but in the winter time and in high humidity situations the window fog causing an additional safety issue. I am also forced to open the windows during this time causing excessive noise and temperature control issue. I called dealer months ago and they said not covered but now I learned should have been covered but now past the 60k mile limit.

I purchased a used 2024 Jeep Grand Cherokee 4xe (approx. 64,000 miles) from EIDE Chrysler in Waite Park, MN on 9/30/2025. On the initial drive home, a “Service 4WD” warning appeared. Before I could return for the axle repair, a Check Engine Light for the hybrid system also appeared. After purchase, I also began experiencing exhaust fumes entering the cabin, which is a health and fire concern. At the time of sale, the dealership provided two contradictory recall printouts for the only recall they disclosed—one stated a remedy was available and one stated no remedy was available. I was verbally told the recall had been repaired. This was inaccurate. After the sale, I discovered that my vehicle now has two open the federal safety agency safety recalls, both with no available remedies: • 25V741 – High-voltage battery fire-risk recall (federal stop-sale order applies). • 25V766 – Engine contamination recall that may cause engine damage or failure. These recalls did not exist at the time of purchase, but the dealership never notified me when they were issued. Stellantis only notified me of one recall; I had to discover the second by checking my VIN on the federal safety agency’s site. The drivetrain warning, hybrid-system fault, and exhaust fumes occurred despite very low mileage after purchase. The vehicle currently has multiple unresolved safety defects, including fire risk and potential engine failure, and cannot be repaired due to lack of available remedies. I have opened a case with Jeep/Stellantis (Case #: 94881053). I am reporting these issues because the combination of drivetrain malfunction, hybrid-system warning, cabin exhaust fumes, and two unrepaired safety recalls poses a significant risk to occupants and other drivers.

Vehicle: 2024 Jeep Grand Cherokee 4xe Limited Issue Type: Fuel System / Fuel Gauge / EVAP / Hybrid Interaction Safety Concern: Incorrect fuel-level indication, fuel overflow, unreliable range estimation Description of the Problem: The vehicle’s fuel gauge and range indicator have become inaccurate and erratic. The gauge showed about 95 miles remaining, then dropped rapidly to a low-fuel warning. At the gas station, the pump shut off at approximately 8 gallons, even though the vehicle indicated low fuel. When I manually resumed fueling, gasoline immediately overflowed from the filler neck. There was no gasoline smell prior to this event. After driving away from the station, the remaining range increased, then decreased again, fluctuating by about ±10 miles. The fuel gauge and range readings continue to be inconsistent and unreliable. These symptoms began recently and are getting worse. The vehicle is currently being operated in Hybrid mode only due to an existing recall advising not to charge the battery. This issue creates a safety risk because: The fuel gauge may not reflect the true fuel level, Overflow during refueling poses a fire hazard, and EVAP or tank-pressurization malfunction may be occurring. Frequency: Problem has occurred on multiple consecutive refueling attempts. Safety Risk: Fuel overflow, inaccurate gauge, possible stalling or running out of fuel unexpectedly. Dealer: Issue reported; diagnosis pending. No modifications have been made to the vehicle.

Yesterday, I had been traveling on the turnpike and was attempting to merge back on from a rest area when the Jeep entered "turtle" or "limp" mode without warning, indicating a failure of the hybrid system. The speed dropped instantly to 2mph and the engine kept revving, generating dark exhaust and a concerning smell (hot, different from regular vehicle exhaust smell). Eventually I was able to move back into the parking area and needed to be towed. I have yet to have it evaluated by a dealership as they are closed today. Following multiple previous hybrid system recalls since purchasing the vehicle Oct 2022, I've experienced numerous malfunctions of the hybrid system (taking it to the dealership multiple times to be evaluated after the "wrench" service hybrid electric system warning showed) over the last 6 months. Each time I've been told a "software reset fixed it" by the dealership. The problems with this hybrid system have been increasing in severity. Currently two recalls are in place due to these hybrid system issues (remedy not available). This was a scary, dangerous experience and I have no confidence in Stellantis resolving this issue.

The Jeep has had major issues with the fuel system. The first reported issue is during the fill the filler would click like it was full when it was in the beginning stages of the fill. It ended up soaking me with gasoline and shutting down a gas station for spill. I filed a complaint with the federal safety agency and the Vermont Attorney General because the dealerships were not fixing the problem. The fuel tank was finally repaired when the Attorney General got involved. 2024 the Jeep is again having issues with the fuel system. When the tank is filled to capacity it creates gasoline fumes so strong that it infiltrates the cabin and can be detected from the parking lot. It is really scary to keep having issues with the fuel system. I am shocked after reading on the internet so many Jeep owners with fuel system issues that the vehicles are not on recall. I want to report this because it is a safety issue.

My JGC 2014. I was on a 5 lane interstate in the far left lane when my car started decelerating at a speed of 64mph. As I was merging into the left emergency lane it switched into neutral gear. I then proceeded to stop and put the Jeep into park and turn it off. Prior to this incident my check engine light had just illuminated a month prior and I ran a diagnostic computer test and it returned stating it was an EVAP problem. I haven’t had any systems. So I was waiting on my first check to get it taking care of (meaning no gas smell in the cabin, no fuel leaks under vehicle, no bad gas mileage). So the police came to my rescue and helped me pull the emergency neutral pull in the middle console in order to get it off closer to the median so I wouldn’t get hit until I could get a tow. Well it wouldn’t turn over again. It sounded like I had a fuel pump problem but when I went to turn it on but not over I heard my fuel pump cut on. So no problems there! So my battery started running low in voltage so I charged it with a battery pack and it got around 13 v and I unplugged it . It’s a 14 v battery. Well I got my vehicle turned in the off position the emergency neutral gear unlocked and then my windshield wipers started and the car was not on . I heard clicking in the fuse part under the hood so I found that fuse and pulled it. I think took a fuse checker and checked every fuse in my box they all had fire. On my dash it started saying system brake suspension and the check engine light was off. So I checked it with the computer diagnostic tester and it said a code of all U’s which were the ECU and the TCM and the gear shifter which was the only P.O. code. So we took my gear shift off and cleaned it and hooked it back up. It was nasty. And it would slap again but not show on my dashboard. So I reset my battery and nothing. I am so upset about this. I’ve worked on every vehicle I’ve owned and this is mind boggling. Everything is up to date and seems fine

I experienced a strong fuel smell on filling the tank of my Jeep. The dealer and an independent diagnosed a cracked fuel tank. The tank had 3 cracks in the top of the tank which allowed fuel fumes to enter the car. The fuel tank was replaced at my cost of $785.11, the problem was solved. This created a very hazardous situation with risk of explosion or fire at any time.
