My 2021 Jeep Wrangler Rubicon (3.6L eTorque, automatic transmission) has had recurring drivetrain instability since about 2,000 miles while under factory warranty. It intermittently has high RPM flare during acceleration, delayed shifting, shuddering under load, and abrupt engagement. At low speeds (about 10–5 mph), it harshly downshifts, grabs suddenly, RPMs jump up and down, and it can feel like it will stall; it has stalled intermittently. Braking feels inconsistent, and at times it feels like the vehicle resists braking or surges before slowing. The forward collision warning/automatic emergency braking has activated with no obstacle present, and the power steering assist has been lost intermittently. There is also an engine tick and a high-pitched whining noise from the engine/drivetrain area. In January 2026, the transmission catastrophically failed and required replacement of the transmission, torque converter, cooler, and control module. The vehicle was out of service for over 24 days. After installation of a new Mopar remanufactured transmission and torque converter, the same symptoms returned. AAMCO has now found that the new torque converter failed, with metal shavings throughout the transmission, in the fluid, and at the bottom of the pan. I was advised that the vehicle should be sent to a Jeep dealership because no codes are currently present. I was also advised that the dealership may replace only the torque converter rather than the entire transmission, despite recurring failure and metal contamination. This presents a safety concern due to loss of acceleration, unpredictable torque engagement, stalling, unintended braking activation, power steering loss, engine/drivetrain noise, and repeated drivetrain failure. I have all the records if requested, file is too large to send in the upload area.

My 2021 Jeep Wrangler Rubicon (3.6L eTorque, automatic transmission) has experienced recurring drivetrain instability beginning at approximately 2,000 miles while under factory warranty. The vehicle intermittently exhibits a high-RPM flare during acceleration, where the engine speed increases without a commensurate increase in vehicle acceleration. The transmission then abruptly engages, causing sudden jerking. At low speeds (approximately 10–5 mph), the vehicle shudders and harshly downshifts, creating a sudden grabbing sensation. Engine RPMs fluctuate during deceleration as if the transmission cannot smoothly match engine speed. Braking feels inconsistent, and at times it feels as though the vehicle is accelerating or resisting braking input before abruptly slowing. The vehicle has felt as though it would stall at low speeds and has stalled intermittently. Additionally, the forward collision warning / automatic emergency braking system has activated without an obstacle present. There have also been intermittent instances of loss of power steering assist. The engine has developed a ticking noise and a high-pitched ringing/whining sound from the engine area during operation. In January 2026, the transmission catastrophically failed and required replacement of the transmission, torque converter, cooler, and control module. The vehicle was out of service for over 24 days. Following installation of a Mopar remanufactured transmission and torque converter, the same symptoms have recurred, including RPM flare, delayed shifting, shuddering, harsh downshifts, unstable deceleration, and abnormal engine noises. These conditions present a safety concern due to loss of expected acceleration, unpredictable torque engagement, unintended braking activation, intermittent power steering loss, stalling behavior, and drivetrain instability. The vehicle is currently under further diagnostic evaluation. I have multiple documents, but the file is too large to upload

Dealers: Lakeland Crysler Dodge RAM, FL; Second authorized Jeep dealer, Bartow FL Complaint: My 2024 Jeep Wrangler Sahara has multiple unresolved safety defects despite repeated warranty repairs, and I have no confidence in this Jeep at just 12,000 miles. Forward Collision Warning (FCW) not working — Lakeland Jeep failed to repair or document inspections. Fuel leak / gasoline fumes in the cabin — After repairs on Feb 4, 2026, strong fumes entered the cabin while my children were passengers. A second dealer confirmed the leak and retained the vehicle as unsafe. sensor failures — Reported since July 2024, still unresolved. Failure to document safety sensors — Repeatedly requested, ignored by dealer and Stellantis. Dealer GM and Stellantis negligence — Cases closed prematurely; repairs rushed without confirming the Jeep was safe to drive. The Jeep continues to pose serious risk to passengers, including my children, due to fuel fumes and non-functioning safety systems. I cannot trust this vehicle to transport my family safely, despite being only 12,000 miles. Documentation: Emails, texts, certified letters, and repair orders document repeated safety defects and communication with Stellantis and Lakeland Motors Jeep. Request: Immediate investigation and warranty repairs Written confirmation that the Jeep is safe before return Buyback under Florida Lemon Law due to repeated unresolved safety defects

What component or system failed or malfunctioned, and is it available for inspection upon request? YES GAS LEAK Engine oil leaks: Timing cover gasket Valve cover gasket with spark plug tube seals Injector O-rings Upper oil pan reseal Leaking rear shocks (suspension issue affecting vehicle stability) Upper oil pan replacement seal (additional engine oil sealing issue) Collision sensor failing (forward collision warning / crash-prevention system) The vehicle is currently at a dealership and available for inspection. How was your safety or the safety of others put at risk? The active fuel leak created immediate fire and fume inhalation hazards inside the passenger compartment, where occupants, including children, were seated. Fuel leak could have caused an engine fire. Engine leaks created risk of stalling or mechanical failure while driving. Leaking rear shocks affected vehicle stability and handling. The malfunctioning forward collision warning sensor impacted a crash-prevention safety system. These combined issues posed serious risk to vehicle occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Confirmed Dec. 8 2025 , dealership never documented sensors added as “miscellaneous.” Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?

Component/System That Failed: The airbag system, forward-collision sensors, and collision-warning/braking system failed. Despite a severe frontal crash, no airbags deployed and no warning or automatic braking occurred. The Bosch Crash Data Report shows abnormal sensor spikes (up to +52g), inconsistent Delta-V readings, and failures in object detection (“No Object” recorded before impact). The components remain available for inspection through the body shop and insurer. Safety Risk: My family and I were injured because the vehicle provided no warning, no crash avoidance, and no airbag deployment during a major impact requiring a full frame replacement. This failure places all Jeep 4XE drivers at risk of severe injury or death in similar conditions. Has the Problem Been Reproduced? The problem occurred unexpectedly during the crash and cannot be safely reproduced. However, Stellantis’s inspection did not explain the sensor irregularities or system failures. Vehicle Inspections: The vehicle has been inspected by Stellantis (File 94277361), my insurance company, and the collision repair center. Stellantis claimed “insufficient deceleration,” which contradicts the severity of damage, sensor data irregularities, and the fact that the other vehicle’s airbags deployed. Warning Lamps/Symptoms Before Failure: For weeks before the crash, the Jeep produced false crash warnings, beeping, and forward-collision alerts with no obstacles present. During the actual impact, all warnings stopped, and the system failed completely. This sudden shift from false alarms to total silence suggests a sensor or module defect. Urgency: Multiple active recalls already affect this vehicle line. I fear this Jeep is unsafe to drive even after repairs. I am requesting the federal safety agency’s urgent assistance and investigation into this failure to prevent further injuries.

Received over the air Uconnect software update immediately thereafter, vehicle began stalling and putting itself in park before Jeep issued recall A7C (the federal safety agency 25V‑710). Vehicle was towed to Glendale Jeep (Glendale, CA) on 10/11/25 and returned 10/24/25. Dealer mis-stated vehicle out by date on repair order. Upon receiving vehicle back and driving, still noticed a lack of power when accelerating. On 10/26/2025 vehicle infotainment system stopped working, and all infotainment-controlled safety related features stopped working (Collision avoidance, Back up camera etc.). I Reported incomplete repair back to dealer on 10/27/2025. Dealer states that they cannot accept vehicle back for repair as the fix they provided was only temporary. Jeep only provided them a temporary fix and Jeep has not released a complete comprehensive fix. Dealer never disclosed this repair was only temporary when the vehicle was picked up, despite having knowledge of this. Dealer now states that they cannot accept vehicle back or any affected vehicles at this time because they have too many affected Jeep on the lot awaiting the temporary repair. Contacted Jeep numerous times and filed claim. Jeep is delaying rental reimbursement payment under their wave program and not directly providing direct rental replacement vehicle either despite having been sent receipts and proof of repair work order. My vehicle and other Jeeps are not safe to drive with the temporary fix Jeep provided, as the safety features are not functioning. Additionally, The dealer should have not released the vehicle back with knowledge that these safety systems may be compromised. It puts my safety and the safety of other motorist on the road at risk. As of 10/28/25 ,Jeep and the dealer have not provided any instructions on what to do or how to proceed. Vehicle cannot be repaired at this point.

Jeep pushed an OTA Software Upgrade on 10/10/2025. The following morning 10/11/2025, while operating the vehicle. The vehicle lost all propulsion and power steering. Check Engine Light Came on and a message “Shift to P to Start” message appeared on the console. Additionally, the traction control system, collision avoidance alarms appeared on the console. Fortunately I was able to navigate the vehicle to the shoulder of the road without getting hit. However, I fear had my newly permitted teenage driver been operating the vehicle the outcome would have been much worse.

I had the most recent incident driving Westbound in the evening hours shortly before Sunset around October 10, 2024. It appears the sunlight from the setting sun triggered my adaptive cruise control and forward collision alert and triggered an alarm sound and activated emergency braking at the same time. I have had two previous incidents like this. One at the exact same location on my commute home at around the same time and maybe a week before. A third occurrence was on an Eastbound morning drive with the rising sun. All three incidents triggered emergency braking from a speed of ca. 65mph. I was able to react fast enough to deactivate the ACC by lightly pushing the brake pedal and could avoid serving or complete stopping of the vehicle. Luckily during all incidents I had no close traffic behind me, otherwise the incidents could have caused a rear end collision.

I was driving on the highway merging on a bridge before entering a tunnel, there was a car in from of me that was rolling slow. My Forward Collision Warning did not go off when the car was in front of me but when the car was about 3-4 car lengths away and was driving away the warning went off and the emergency automatic brake engaged and there was nothing in front of me. I was almost rear ended and could not get my Jeep to move. The automatic brake disengaged and I was then able to drive normally.
