Adaptive Cruise Control problems of the 2024 Jeep Compass

The vehicle experiences severe, recurring electrical and drivetrain failures while operating at highway speeds (up to 70 mph). On August 8, 2026, while driving on the highway, the vehicle suffered a sudden loss of motive power/drivetrain engagement accompanied by non-stop audible warning chimes, cluster warning light cascades, and an svc 4wd (service 4wd) message disabling drive modes. This sudden loss of power on a high-speed highway created an immediate, near-miss collision risk for my family and surrounding traffic. Service & repair history: the issue has recurred across multiple dates (June 30, July 4, July 10, July 14, and August 8, 2026). The vehicle was held by castle Chrysler Dodge Jeep ram naperville for nearly three weeks (July 14 – August 7). The dealer cleared diagnostic trouble codes (dtcs) and returned the un-repaired vehicle, stating that stellantis is "working on a software fix. " the failure recurred twice immediately after pickup on August 8 at 13,662 and 13,696 miles. The dangerous highway loss-of-power condition remains unrectified.

Multiple critical safety systems fail intermittently: automatic emergency braking (aeb) disables itself randomly while driving, lane steering assist becomes unavailable, frequent ‘service 4wd’ warnings, and ‘power steering system hot - performance may be limited’ warning. Issues worsened after transfer case replacement on April 27, 2026. Dealership admitted ‘these lights appear all the time… there’s nothing we can do. ’ this matches many other 2024/2025 Compass complaints on NHTSA. I no longer feel safe driving the vehicle. The car has also been using a lot more gas since these issues started. I’m not sure what date this started, but the first time (1/3) that I brought it to the dealership was March 20th 2026.
