Filed Oct 25, 2026 · Brakes, Fuel system · NJ

On 8/16/2026 the vehicle seized completely while driving. No power. No steering. No brakes. Obv my safety and the safety of the passengers in the vehicles and trucks that had to avoid me was serious. My vehicle was towed to the closest dealership for repair. I picked the 'repaired' vehicle up on 9/23/26. Within a few miles of leaving the dealership with said repair, the vehicle once again lost all power while driving. No power. No brakes. No steering. This was on a 55mph highway and the safety risk for me and others was severe! As of today (10/25/2026) the vehicle is still in the dealership with multiple but unsuccessful repair attempts.

This has happened on multiple occasions. While driving in Hybrid mode and the battery power reaches 0% there is a very sudden and dramatic drop in speed/power. Especially jarring at highway speeds. Yesterday was on the highway at 60+mph and it was like the engine died for 2 seconds or so while the car was switching power modes or draw. This is becoming more frequent with this vehicle and the modes it occurs in seem to be increasing as well. All Battery mode was when first noticed - but I don’t know the trigger. This time was Hybrid mode where the trigger seemed to be the battery running out of juice and activating the ICE. Unsafe. Scary.

The contact owns a 2021 Jeep Wrangler. The contact stated that while driving at various speeds, the vehicle experienced a loss of power steering assist, causing a more difficult steering effort. The vehicle was restarted to correct the failure. The vehicle was taken to the dealer, who replaced the CAN bus connector, but the failure persisted. While driving 70 MPH, the steering wheel seized and the vehicle almost crashed into a guardrail. The contact sustained body soreness. The contact later received notification of the federal safety agency Campaign Number: 26V363000 (Steering). The vehicle was towed to the second dealer, Nielsen Dodge Chrysler Jeep Ram of East Hanover (175 NJ-10, East Hanover, NJ 07936), who informed the contact that the electric hydraulic power steering pump needed to be replaced; however, the dealer refused to perform the recall repair and stated that the failure was not related to the recall. The manufacturer was made aware of the failure by phone. The failure mileage was approximately 60,000.

There is no plan for repair or timing of new engine replacement. I filed formal notice of dissatisfaction and intent to pursue all available legal remedies.

The contact owns a 2019 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, one of the brake calipers locked up, causing the vehicle to veer from side to side during acceleration. The vehicle was driven to an independent mechanic, where a technician diagnosed it with a seized brake caliper. Due to the constant dragging, the brake pads wore excessively and failed to slow the vehicle properly, extending the stopping distance. The brake parts were replaced, and the vehicle was repaired.

On approximately 95% of my driving trips, my 2024 Jeep Wrangler 4xe suddenly and unpredictably loses acceleration or drive power. When I press the accelerator, the vehicle does not respond or accelerate normally. A warning then appears stating that electric mode is unavailable. After several seconds, the vehicle begins operating normally again. There is no apparent pattern, and this has occurred while traveling approximately 50 to 70 mph. The malfunction appears to involve the hybrid propulsion or power-control system. The vehicle is available for inspection. It is included in FCA Recall A7ululo:\/\/A nawe7Cl7C (the federal safety agency Campaign 25V‑710), which concerns loss of drive power associated with an over-the-air software update. No remedy is currently available. This condition putssafety because I cannot rely on the Jeep to accelerate or maintain power when needed. At highway speeds, it could prevent me from responding to traffic, merging safely, or avoiding a hazard. I have stopped driving the Jeep on highways whenever possible and use back roads instead. The dealership has not yet reproduced or diagnosed this specific problem, although the symptoms are consistent with Recall A7C. The vehicle has received service for other recalls and is awaiting an engine replacement under a separate recall. It has not been inspected by police, insurance representatives, or an independent repair facility for this issue. There is generally no warning before the loss of acceleration. The “Electric Mode Unavailable” message appears after the malfunction begins, and normal performance returns several seconds later.

I left my home for work on XXX. I noticed a lack of propulsion upon stepping on the gas & air conditioning blowing warm air. At a stoplight ([XXX] and [XXX] in [XXX]), I attempted to restart the vehicle in hopes that a reset may fix any issues. What I found was that my vehicle would not restart and I could not remove it from park in a busy intersection. After 30 minutes of trying, I was able to get it to turn on and move to the Burger King parking lot. A tow truck arrived and took me to the [XXX] Valley Chysler Dodge Jeep Ram dealer. They told me it would take until Tuesday XXX to look at it. They could not offer me a loaner nor a rental vehicle. They called on XXX and said it was a battery defect and may take weeks to repair. To date, my vehicle with 27,000 miles have been in for four separate recalls, citing lack of propulsion, risk of battery fire. Zero accidents. I no longer feel safe driving the vehicle after recalls: "the 2.0 engine may be contaminated with sand from the casting process ... leading to catastrophic engine failure." "firmware software...may cause loss of drive power which can cause a vehicle crash." "The high voltage battery may become damaged during normal vehicle operation ... advising owners to park away from structures or other vehicles" "Electric Hydraulic Power Steering Pump may have electrical issue ... may lead to a fire." The manufacturer and dealer are offering minimal insight or restitution for my experience or safety. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on the highway, the vehicle suddenly lost power and would not accelerate beyond approximately 60 mph. This created a safety risk because I could not maintain normal highway traffic speed. I brought the vehicle to an authorized dealership, where a recall repair was performed. However, the same loss-of-power issue occurred again. After further inspection, the dealership informed me that the vehicle is subject to Safety Recall 78C and requires a complete engine replacement. I am not a technician and cannot determine the exact cause of the failure; I have relied on the dealership and Stellantis for diagnosis and repair. The dealership confirmed that the replacement engine is on backorder and the repair cannot be completed. My vehicle has been at the dealership since June 2, 2026, and has been unavailable for nearly two months. The vehicle is available for inspection upon request. Neither the dealership nor Stellantis has provided an estimated date for parts availability or repair completion. The timeline is UNKNOWN. The recall and engine replacement requirement were confirmed by the authorized dealership. The vehicle has not been inspected by police or insurance representatives. Manufacturer inspection is UNKNOWN. I do not recall any warning lamps or messages before the power loss occurred. I continue to make monthly lease payments for a vehicle I cannot use. No loaner vehicle was provided. Stellantis offers rental reimbursement of up to $50 per day, but this does not cover actual rental costs. Even the least expensive rentals in my area exceed $50 per day, requiring me to pay additional expenses out of pocket. This is the second time a manufacturer recall has caused an extended loss of vehicle use. A previous recall kept my vehicle unavailable for more than one month. My lease expires in February 2027, but I continue paying while the vehicle remains unusable. I requested a buyback due to the lack of a repair timeline, but Stellantis denied my request

My 2024 Jeep Wrangler 4xe has been subject to four safety recalls in the ten months I have owned it, three involving vehicle fire risk: 56C/25V‑527 (TPMS, completed), 68C/25V‑741 (high-voltage battery cell separator damage/fire risk, completed), 78C/25V‑766 (casting sand contamination of the engine), and 21D/26V‑363 (electric hydraulic power steering pump overheating/fire risk). Recall 78C was announced November 6, 2025, warning that my engine may be contaminated with casting sand and may suffer catastrophic engine failure, a vehicle fire, or an unexpected and unrecoverable loss of propulsion. More than eight months later, no remedy has been performed on my vehicle and the recall remains open. Recall 21D is also open, with FCA instructing me to park outside and away from structures because the vehicle may catch fire even while parked with the ignition off. Under recall 68C I was previously instructed not to charge the vehicle.
