2021 Jeep Wrangler

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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.

Unpredictable complete loss of power steering that will continue until the brakes are applied and speed is reduced to approximately 30 mph and voltage level spikes, as high as 16.3 volts as shown on the instrument panel. It is not temperature related. When disabled it requires two hands and extreme strength to turn, especially when taking an off ramp. Voltage level is typically ranging between 12.7 - 13.7 volts during normal conditions as well as when in no power steering conditions. The first trip 3-4 months ago to the dealership and the only finding was a corroded ground loop which did not solve the issue. After no success begging for a loaner car we left the Jeep 19JUN25 while on vacation for second trip this week. I requested them to contact Stellantis STAR Center and this is the report: 24JUN25 Good morning - our STAR case engineer pointed us in the direction of a similar STAR publication that we had followed the last visit. I did not find any faults within the charging system or any voltage regulators at this point. There were 5 labeled grounds in this publication that were common for building up corrosion. The ground that is on the frame near the driver rear close to the 48v battery had a large amount of corrosion. He cleaned up each ground and applied dielectric grease yesterday, so now I am having him take on a few test drives to see if the issue persists. I have a video of the spike leading to steering reengagement but unable to upload it.

I own a 2021 Jeep Wrangler 4xe Unlimited, which has undergone three manufacturer recalls and two separate service (one handle during a recall visit) visits due to charging failures. The recalls were related to defrost system malfunctions, sudden loss of motor power, and high-voltage battery concerns. Each of these issues was addressed solely through **dealer-installed software updates**—updates that could not be completed over the air. These recalls and service visits highlight a troubling pattern: the vehicle’s core systems—including the BPCM, IDCM, PIM, TCM, and HCP—are deeply interconnected and dependent on one another. So far, my vehicle has required a total of **10 software updates**, with some systems needing multiple revisions. Most recently, Jeep addressed a “not charging” problem by once again performing a software update—this time affecting **five of the seven systems previously updated during recalls**. Despite the problem originating from their software architecture, Jeep charged me **$200 for the update**, even though it stemmed from an issue caused by their failed over-the-air deployment strategy. These recurring failures are not isolated incidents—they represent a systemic flaw within the vehicle’s hybrid management and safety systems. Relying on repeated software patches to resolve critical defects is not only unsustainable—it’s creating **unsafe driving conditions** and placing an unfair burden on the owner.

Coolant leaking, engine overheating, dealer says not covered issue despite it being a known issue (see customer satisfaction notification zd8 coolant leak. But dealership is going to charge me over five hundred dollars to replace a gasket and use some lock tight on my vehicle. I understand there isnt a RECALL on my vin in particular but I also can read and the narrative in the above mentioned notification matches my vehicle. 2021 Jeep Wrangler Unlimited 2.0 turbo engine. So why am I paying out of pocket for a "known" issue?
