2021 Jeep Wrangler

I experienced an extreme coolant leak caused by the coolant inlet tube fasteners backing out and becoming loose. This is consistent with MOPAR recall CSN ZD8 for 2021-2022 Jeep Wrangler. My vin does not seem to be covered by this recall but experienced the same issue. I request that the VINs be extended to include my VIN.

It started with the engine sounding louder then normal. Then a bad smell in the cab of the vehicle. Later found out it was a exhaust leak that was getting into the vehicle causing headaches and other symptoms of carbon monoxide. Also note the burn marks around the broken bracket that could cause a fire if not mechanically inclined to notice. Not check engine light for this. But when I spoke to the dealership it wasn't new to them. Apparently this has happened to alot of the ecodiesel jeep and gladiators. A common problem that should be resolved before and life threatening injuries result in loss of consciousness or fire.

From the moment I drove off the lot, I encountered problems. The battery light came on immediately, requiring a replacement within weeks. I returned to the original CarMax location for this service. However, this was only the beginning. Over time, I discovered the following: The driver seatbelt was not functioning properly The right rear passenger seatbelt buckle was completely missing The filters were filthy and had not been cleaned or replaced in well over a year, according to a trusted mechanic The engine may now require replacement at just 38,000 miles When I called CarMax to report the missing seatbelt buckle, I was incorrectly told that my vehicle was not under warranty. This was untrue — I was well within the warranty period at the time. Despite this, I was ignored, and the safety concern received no follow-up or correction. This points to either a falsified or negligent vehicle inspection at the time of sale. Your "125+ point inspection" failed to catch multiple clear safety hazards and wear issues — or worse, they were deliberately overlooked. What’s most disturbing is that I only discovered the missing seatbelt after my sister drove the vehicle with my [XXX] and [XXX] nephews in the backseat. One child had to sit in the middle because the rear right buckle was completely missing. That realization — that I unknowingly placed children at risk in a vehicle that your team labeled "safe" — is devastating. Now I’m being told that the engine may be failing — and it hasn’t even hit 40,000 miles. I was recently asked by the Southlake service team to provide oil change records, which I am willing to share. But let’s be clear: An oil change receipt does not explain why a newer engine is failing at this mileage — unless something much deeper is wrong.

While operating the 2021 Jeep Wrangler under normal driving conditions, I experienced repeated overheating issues. A high-pitched noise was consistently heard coming from under the hood during operation. Simultaneously, the engine temperature gauge would spike to high, and the infotainment system displayed an engine overheating warning. When the vehicle is started from a cold start - the high pitch is constant. To prevent damage or risk of fire, I immediately pulled the vehicle over and allowed the engine to cool. Upon restarting, the overheating issue persisted, with the temperature gauge rising and falling erratically—up to four times during a 15-minute drive. I brought the vehicle to an authorized Jeep dealership service center for inspection. The following findings were documented: Coolant System: High-temperature coolant reservoir found completely empty. Low-temperature reservoir found low on coolant. Evidence of coolant leakage at multiple coolant line fittings. Engine Block: External head gasket leak observed. Pressure test confirmed leaks in coolant lines. Internal Engine Inspection: Spark plugs were removed and coolant residue was found in the combustion chambers. Cylinder walls showed damage consistent with overheating. Slightly burned valves noted during inspection. Based on the findings above, the engine has suffered critical failure due to overheating and internal coolant leakage. The combination of external gasket leaks, coolant residue in the cylinders, damaged cylinder walls, and burned valves presents a serious mechanical and safety concern. Full engine replacement is required. Estimated cost: $16,000.00 This engine failure may pose a significant safety risk due to: Sudden loss of power while driving, Potential engine fire from overheating, Exposure to steam or hot coolant under hood Risk of engine seizing while on motion.

June 5, 2025 stopped at red light turned green tried to turn left and the jeep flashed the electric red bolt symbol and check engine light came on lost all power would not go when gas pedal was pushed. a/c lost power started blowing hot air and engine turned off. Restarted engine finally got it to go enough to pull out of traffic. Turned off engine opened hood checked battery cables, fuses and all was intact. Started engine drove slowly to the Autozone store to have the diagnostic test done and it showed P2101 power train system throttle actuator A control motor circuit range /performance detected unexpected voltage on the throttle actuator control motor circuit also C121C-00 ABS torque request signal denied Anti-lock Brake System U0401-00 implausible data received from ECM/PCM “A”. System was reset to be able to drive home. 6/16/25 went to start jeep to go to work made a clicking noise check engine light on and the voltage warning sensor flashing and showed Service Electronic Stability Control error would not stay running checked battery cables fuses and restarted engine tried to back out of driveway engine would not go. Had jeep towed to Moore CDJR dealership where it was purchased from 9/2023 to have serviced found throttle body needs replaced dealership contacted several parts dealers, Mopar, and other dealerships etc. to locate the part needed was advised couldn’t find the parts needed for the repair. Contacted service department and they advised they were calling National Auto Care my extended warranty for approval for repair. My concern is if I had been driving 65 mph and it went out I would have been in a accident when the vehicle stopped functioning. Safety of myself and other drivers would have been compromised. This is the 2.0L Turbo motor and have been advised that there are several issues with this motor and should trade in vehicle. I don’t have that option and this is the only vehicle I have.

My jeep started leaving me stranded 8 times. The jeep would not start but had warning lights of " service charging system" , with picture of a battery in left of dash, a wrench, engine light, and it won't go into neutral to have it towed. I had it in the shop twice, and they cannot figure out the cause. They did update the computer to cover the recall from automatic combustion. { updated the computer) . It got worse, the car is now cutting off while on. I had it towed to the jeep dealer aging tonight . The dashboard lights do not come onto until after engine failure. This is a hybrid, I was told by Crossroads to keep the vehicle charged but this has not corrected the problem.

The contact owned a 2021 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. No warning lights were illuminated. The vehicle was started, however, the vehicle failed to start as intended. The contact drifted the vehicle to the shoulder of the road. The contact stated the rear of the vehicle was filled with smoke. The contact exited the vehicle. The contact stated that within five minutes, the fire was coming from the hood compartment. The vehicle was towed to the local tow yard. The vehicle was condemned as a total loss. The contact referenced an unknown recall repair, which had a similar failure description, however, the contact's VIN was not associated with the unknown recall repair. The manufacturer was not made aware of the failure. The failure mileage was 28,000.

Since we have had the high pressure fuel pump recall completed/replaced, there have been ongoing problems with the cooling system that cause overheating multiple times, on the same grade of road, during subsequent trips. The vehicle alerts and says it has overheated, and is stopped and allowed to cool off. Coolant is indeed low, but there are not any visible leaks and there is no puddling or areas where it appears to be leaking. We have had this issued looked at twice, several repairs completed, hoses replaced, reservoir replaced, and we are still having this issue. This appears to be something exclusive to the diesel motor, as we have friends with the same vehicle with gasoline engine that are not having this concern.

2021-2024 jeeps with 3.6 penstar are being sold with camshafts that go bad at around 60-80k miles. There needs to be an immediate recall. I have mine at just under 70k and recently had to spend 3 grand to get it fixed with a new part all because the warranty is up and there’s no recall out for it. This is absolutely unacceptable.

I am writing to formally file a complaint regarding ongoing and unresolved safety and reliability issues with my 2021 Jeep Wrangler 4xe, purchased from Heritage Jeep in Logan, Utah. Since acquiring the vehicle, I have experienced repeated and severe electrical failures, including: The vehicle failing to start on numerous occasions Complete loss of electrical systems (dash, lights, ignition) Batteries failing to hold or receive charge Multiple warning indicators that do not resolve after service attempts These failures have rendered the vehicle inoperable for over 65 days total since the date of purchase. Despite multiple service visits and numerous documented attempts to address these problems, the dealership—Heritage Jeep in Logan—has not been able to resolve the underlying issue. I have retained all service records, work orders, and correspondence to support these claims. This issue not only causes significant inconvenience, but it raises serious safety concerns, especially when the vehicle becomes unresponsive or loses power without warning. I believe this may reflect a defect in the vehicle’s electrical or hybrid system and warrants investigation to protect other consumers. I am requesting that the National Highway Traffic Safety Administration (NHTSA) open a formal investigation into this vehicle and hold the manufacturer and dealership accountable for the ongoing safety risk and failure to adequately repair or replace the vehicle under warranty. I was also in regular contact with Jeep Corporate throughout the ongoing issues, but they stopped responding before a resolution was reached. I have retained all email correspondence documenting those interactions.
