The contact owns a 2018 Jeep Wrangler. The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 23V116000 (Power Train); however, the failure persisted after the recall repair. While driving 15 MPH, the instrument cluster failed to display the gear that the transmission was shifted to. Several unknown warning lights were illuminated, and the vehicle failed to turn off. The contact stalled the engine and waited for the vehicle to shut off. The vehicle was taken to the dealer, who determined that the instrument cluster had damaged the transmission and CAN C bus connector. The dealer replaced the instrument cluster, transmission, and CAN C bus connector, but the instrument cluster again failed to display the transmission gear. The manufacturer was made aware of the failure by phone. The failure mileage was approximately 54,000.

I had Recall issue occur on my 2018 Jeep Wrangler JLU #19A Clutch Assembly. The issue also damaged the Transmission as stated possible in the recall. Additionally the dealership reported that recall required replacement of the cluster (Instrument cluster with all gauges). This was all done. However, upon picking up the jeep and driving home, I realized that the cluster was no longer showing what gear the car is in. I called and reported to the dealer. They asked me to bring in as they though might be a software update or something, they would hook to machine. In the meantime the jeep started experiencing issues where every emergency light on cluster would go off. I would lose power steering, and I could not even turn the car off. I had to stall the car to get engine to stop. I took back to dealer (Cherry Hill Jeep) the reported the "star connector" or Can C-Bus Connector needed to be replaced. I explained that this never occurred prior to recall issue so it must be covered. they said they did not know. They replaced. I went to pick up and still the car did not show the proper gear. after further review by the dealer, they believe they received and installed the wrong cluster. This cluster now caused a problem with the Can C-Bus connector, and the car still does not show what gear it is in. All cars show what gear the car is in. this jeep currently does not. the dealer claims that the software update does not include the gear. This is not how i purchased the car or how i dropped it off prior to recall issue. Dealer is trying to charge me for labor of Can C-Bus connector and install for over $1000 and the car still does not show the gear. I have claim with Stallantis #98090202 they keep pointing to dealer. Dealer keeps pointing to Stallantis. A car must show the gear. This is safety concern to drive the car.

The vehicle experienced a fuel/propulsion failure involving sudden loss of engine power. After internal engine repairs performed by the dealership (camshaft and valvetrain work), the vehicle was returned to me as repaired and safe to operate. Within minimal post-repair driving (less than one mile), the vehicle entered limp mode, lost propulsion, and the engine shut down while driving in active traffic. The vehicle required towing back to the dealership. The loss of propulsion occurred on a busy city roadway and created an immediate safety risk to me and surrounding motorists due to the sudden inability to maintain speed or power, with a foreseeable risk of collision. The problem has been confirmed by the dealership. After subsequent inspection and teardown, the dealer documented catastrophic internal engine damage, including cylinder wall scoring and a failed head gasket. The dealership acknowledged that deeper inspection during the prior internal engine repair would have revealed the need for engine replacement. The vehicle has been inspected by the dealership multiple times and by the dealership’s insurer. The manufacturer (Stellantis) has opened a customer care case. The vehicle is currently available for inspection and has been removed from service due to safety concerns. Prior to the failure, the vehicle displayed warning indicators and messages at the time of the incident, including limp mode activation and critical alerts immediately before and during the shutdown. No warnings were provided to me at the time the vehicle was returned from repair regarding unresolved internal engine risk or potential loss of propulsion.

Faulty CANBUS connector/CANBUS failure. This issue tends to be a random and inconvenient occurrence which can be difficult to initially diagnose. Causes the jeep to stall, power steering to fail, causes all dash lights to light up and keeps the jeep from start up. Acts as if the part needs to cool down before the jeep will restart. The failure of this part has caused the jeep to stall on the highway at high speeds. Two manufacturer dealers inspected the battery, auxiliary battery, alternator and starter; found no issue with those parts. One dealer said our issue was due to the ABS module; replaced it and it did not fix the issue. Replaced the CANBUS connector and the issue has resolved. This is a known issue among jeeps both new and old and can pose a serious safety risk. To answer the question of how fast the vehicle was going when this issue occurred; the failure of this part happens at both highway speeds and residential speeds. There are currently 52,XXX miles on our jeep and the failure started, roughly, April of 2019. Jeep was purchased, brand new, April of 2018. It started with the jeep failing to start then grew to the jeep entirely stalling out while driving.

The fuel pump relay that is embedded within the Totally Integrated Power Module (TIPM) failed on my 2018 Jeep Wrangler JK Unlimited after only 47391 miles, causing intermittent engine stalls and problems starting. When taken to the Sisbarro Deming, NM CDJR dealership for repair, there were no replacement TIPMs in the stock system available to fix my vehicle, despite my vehicle being only 7 years old. This suggests an abnormally high rate of failure if the manufacturer is unable to maintain an adequate stock to support their vehicles. Given this has been an issue with Jeeps of previous model years (1), it is evident the problem has not been addressed yet.

My 2018 Jeep Wrangler JL Sport is experiencing multiple premature engine failures that present a serious safety risk: •Vehicle overheats while driving. •Recurrent misfire on Cylinder #5 (DTC P0305). •White exhaust smoke with a sweet coolant smell on cold start. •Coolant loss despite recent refill. •Oil contamination with metallic particles found during inspection. •Valvetrain noise from the right bank, suspected intake camshaft wear. These conditions create a risk of engine seizure or sudden stalling while driving, which could cause a crash. Manufacturer awareness: Jeep/Mopar has issued bulletins acknowledging these exact problems, including: •TSB MC-11018482-0001 (May 2025): Intake camshaft/rocker wear causing misfires (P0301–P0306). •Customer Satisfaction Notification ZD8 (2023): Coolant inlet tube fastener issue causing coolant leaks and overheating. My vehicle’s symptoms directly align with these known manufacturer issues. Despite this, Jeep/Mopar has denied goodwill repair coverage. Safety Concern: This defect is not just a performance issue — it creates a high probability of sudden engine stall or seizure, endangering me, my passengers, and other drivers. I am requesting the federal safety agency investigate premature engine failures on the Jeep Wrangler JL (3.6L Pentastar) and require Jeep/Mopar (Stellantis) to address this safety hazard.

The vehicle will intermittently struggle to engage in 1st gear, the brake pedal gets hard, the auto stop start light will display on the dash and the esc light will display on the dash. Each issue may occur separately, not at all or they will all occur within 5 mins of driving the vehicle. I have been at a traffic light where the vehicle would not immediately engage in 1st gear and the vehicle behind me came within a few inches of rear ending my vehicle when I did not begin moving with the flow of traffic. I also have a similar experience with the auto stop start system failing while at a traffic light which caused the vehicle to stall in the intersection and I could not restart the vehicle without completely power cycling the ignition two times. The problems have been reproduced on multiple occasions throughout the past month. The vehicle has not been inspected by a 3rd party and the warning lights and alert messages that appeared for auto stop start system/ esc system did not appear until the problem occurred.
