    I have a 2021 jeep wrangler and the brake hose went on the driver front side. Mopar product ID is 68307451AH. I have called numerous dealerships and Mopar themselves. They informed me this hose is on backorder for over 841 jeeps, and they are unable to get this across the US. Knowing how many jeeps are needing this hose, is it possible to get a recall on it due to the fact it is imperative to fix right away? I've been trying to find a replacement or an alternate but no luck. This is my only mode of transportation and don't want to keep driving my jeep as it continues to veer to the right due to the faulty hose I'm experiencing.

    On 7/13/25, my 2021 Jeep Wrangler Unlimited with approximately 50,000 miles on it spontaneously caught fire as I was driving down the highway. The fire appeared to start in the engine compartment and very quickly moved to the entire front end of the vehicle. I pulled over on the side of the road and managed to safely exit the vehicle without physical injury. In minutes, the entire vehicle was consumed in flames. The fire department arrived within 10 minutes. When I departed the scene of the incident, fire fighters were still spraying water on the vehicle. After leaving the scene, I went to the hospital for psychological injury related to the incident. The investigation into the fire is currently underway. I do not have additional information about the cause or specific location of the fire. The vehicle is currently at a tow yard and is a total loss. It is nearly unrecognizable aside from the frame and a few components in the far rear. I am in the process of documenting all upgrades and modifications. Since it was fully built for off-roading and overlanding, it is a long and challenging task to take inventory of every part. Approximately 3 months before the incident, the vehicle was towed to a local CDJR dealership for a factory recall, where the entire fuel system was replaced. There were no other issues with the vehicle.

    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.

    Defrost system comes on randomly for approx 45 seconds after starting the vehicle regardless of whether or not climate control is on, and regardless of outside temperature, engine temperature or other settings in vehicle. After the 45 secs, climate control returns to whichever current setting is and continues to operate normally.

    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.

    1. What component or system failed or malfunctioned, and is it available for inspection upon request? The hybrid-electric system, including the high-voltage battery, battery pack control module (BPCM), and associated cooling systems, repeatedly malfunctioned. These failures caused loss of power while driving, electrical odors, and error messages. The vehicle is currently at the dealership for service and is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The vehicle has lost power multiple times while in motion, including on city streets and highways. These unexpected power losses significantly increased the risk of rear-end collisions and limited my ability to safely accelerate or steer in traffic. I have had to take anxiety medication when driving the vehicle due to fear of these events recurring, and I am deeply concerned about the safety of my family, including a newborn passenger. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issues have been confirmed by an authorized Jeep dealership on multiple occasions. Despite several recall campaigns and attempted repairs, the same power loss and electrical system problems have recurred. Service advisors and technicians acknowledged the problems and attempted component replacements and reprogramming, but the malfunctions persist. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected and serviced exclusively by an authorized Jeep/Chrysler dealership (Autonation CDJR in Roseville, CA). There is no indication that FCA/Stellantis corporate has physically inspected the vehicle beyond dealership reports. It has not been inspected by police or insurance representatives. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. Warning lights and messages su

    Vehicle check engine light illuminated along with multiple other lights on the dashboard. It had a difficult time accelerating on its own, very sluggish. At the next light the gas pedal was just tapped and the vehicle began to over accelerate increasing to over 30 MPH in a turning lane while crossing an intersection. Avoided a car accident and pulled into the nearest parking lot. That was the second time that type of incident occurred. The first time, the vehicle was self accelerating during 5 o’clock traffic in Los Angeles. We had to constantly press on the brakes only to avoid accidents until we could exit the freeway.

    ? Title: Loss of Power While Driving on Freeway – Dangerous Malfunction Similar to Recall 23V-116 Complaint Description: I am reporting a serious and dangerous malfunction with my 2021 Jeep Wrangler Rubicon EcoDiesel. While driving on a high-speed freeway (70–80 MPH), all warning lights on the dashboard illuminated—including the check engine light—and the vehicle suddenly went into limp mode, resulting in a loss of power. This occurred in fast-moving traffic, putting me at immediate risk of a crash. This started happening again every time I got on the freeway for 10 minutes. I’ve owned this Jeep for about a year, have never taken it off-road, and have kept it properly maintained. All electrical components, fuses, and systems have been inspected, and no clear cause has been found. The problem persists and is clearly not due to driver use or negligence. This issue strongly resembles Recall Number 23V-116, which states that affected vehicles may experience a loss of drive power, increasing the risk of a crash. That recall was for 2021 Jeep Wrangler vehicles, the same model and year as mine. However, my VIN was not included, despite the fact that I’m experiencing the exact same symptoms described in the recall notice: “A loss of drive power increases the risk of a crash.” This issue began occurring shortly after that recall was issued, and it has happened multiple times, mostly during highway driving—making the vehicle extremely unsafe. I believe my vehicle should have been included in Recall 23V-116, as this is clearly a safety-related defect involving the powertrain or control module software. This is an urgent safety issue, and I respectfully request that NHTSA investigate why this VIN was excluded from the recall and consider expanding the recall to cover additional affected vehicles before someone gets seriously injured or worse. Vehicle Information: •Year: 2021 •Make: Jeep •Model: Wrangler Rubicon EcoDiesel •Transmission: Automatic
