Warnings problems of the 2024 Jeep Compass

We purchased our 2024 Jeep Compass on 12-10-2024 with about 3,000 miles on it. Our problems started on the vehicle on or about Nov. 2025. First the lane assist would go out and we were unable to turn it back on, when we tried the light in the button would blink 2 times then stay on. We reached home and shut car off and when we started it we pressed lane assist and it worked. We drove it for about 3 weeks then it happened again. My wife pulled over and tried to turn on switch again. It blinked 2 times and stood on, she shut off car and then restarted it and the switch worked and lane assist came on. We brought car to service senter and they adjusted front camera and cleared code. The lane assist goes out about once a week and we shut car off and restart for it to work. Now about a month ago all the lights on dash went on and the warning lights on both mirrors stood on. We brought car to dealer on 04-29-2026 with the lights on and left car. The dealer said they found these codes, b178f-12, u0422 and u148d. The dealer said they found no updates for this concern and cleared codes and performed proxi alignment and they road tested and no codes came up. We took car home and about 2 weeks the lane assist came back on and had to shut off car to reset it. My wife is worried to drive alone in the car. I have brought the car in at least 3 times for lane assist . Please let us know what to do. . .

The collision alert warning lights have been coming on since the day I drove out of the dealership! they tried to dismiss it as my fault - I got too close to something (I was simply passing another car). This has been a constant issue and I’ve told the dealership every time I’ve had it serviced. I’ve had about four times that I’ve been driving at high speeds and the vehicle suddenly slams on the brakes because it’s “thinking I’m gonna hit something. ” usually it’s if I’m passing another car, but it’s also happened when there is nothing near at all. This past week was the last straw!! I was going 70 mph down the highway, had just passed a semi, and all hell broke loose. Jerked me from side to side, the brakes engaged and were jolting me, smoking, grinding, and screeching horribly because they would not give up in trying to stop me. Oil dumped all over and a burning smell, shaking and jerking, couldn’t steer, etc. . During this scary time, the service 4wd light and crash alert lights all come on. Thankfully the semi I was passing was paying attention and did not hit me. I was two hours from home so the Jeep was towed to the nearest dealership. I later learned there is a service recall that just came out early March 2026. It’s called 12d and is a software update related to all these codes it’s been throwing and how myjeep has been behaving for two years. Software needs to be updated or can have all this stuff that happened to me… because the systems don’t know what to do?? there is also a service bulletin out there that service techs should be aware of that addresses known issues with the ptu (power transfer unit). I just learned from the dealership that has my Jeep - the ptu is shot!! imagine that! they have a ptu unit ordered but will not know what else is damaged until they tear into it. It shouldn’t take an injury or death to get notices out there when there are known issues. Thank you! this dealership where my Jeep is finally seems to know what they are doing!.

Vehicle traveling at highway speeds 70 mph, will suddenly slam on brakes. While there is nothing in front of the vehicle and or sensor. Weather type was clear not a sight of rain or snow.

Adaptive cruise control & phantom braking: on multiple occasions while traveling at highway speeds (approx. 70 mph), the vehicle has engaged in aggressive "phantom braking. " despite clear road conditions and no vehicles or obstacles in the vehicle's path, the system suddenly slams on the brakes, dropping the speed to 50–55 mph. This creates an immediate risk of a high-speed rear-end collision. The instrument cluster frequently displays service warnings for the fcw, abs, blis and the lane departure systems. Transmission & powertrain hesitation: at lower speeds, the transmission exhibits significant hesitation and "sputtering. " when attempting to accelerate from a low speed or a stop, the vehicle falters and fails to engage smoothly until significant additional throttle is applied. This erratic power delivery causes the vehicle to lurch, which is particularly dangerous when merging into traffic or turning across lanes, as the vehicle does not respond predictably to driver input. Manufacturer/dealer response: I presented these safety concerns to a local Jeep dealership, suggesting a software glitch or sensor malfunction. Despite the vehicle being well within the factory warranty period, the dealership refused to perform diagnostic work or updates under warranty, stating I would be responsible for labor costs because the cause could be "numerous things. ".

Active lane management jerked me off the road disabled my forward and rear crash detection sensor and my automatic high beams were disabled all simultaneously without warning or any sign scared me and my family since then my forward crash section is permanently on and will not go off I have no active lane management it disabled and said service and for the past 2 weeks has been nothing but electrical failure after electrical failure my dealership says there nothing they can do except clear the codes and reboot the system and see if that helps (we did that it didn't work either) so I feel like I'm paying for something that has only lasted me 17,000 miles and is about to quit because the computer in it or something is causing my Jeep to be unsafe.

The forward crash detection detects objects on the side of the road that do not present a hazard. The vehicle then automatically, abruptly brakes causing temporary loss of control in the vehicle. In one instance the system detected the barriers in a construction zone causing me to almost lose control of the vehicle and crash into the barrier. The problem has been confirmed by both the dealership as well as Jeep. The vehicle has not been inspected by the manufacture, police, or insurance. There are no lights or indicators of the issue.

Vehicle causes alerts that the indicated functions are not available or need servicing. Vehicle has been serviced at Jeep dealer for repair but continues to emit false messages that the stated safety features are not available. This is a safety hazard due to the alerts causing distraction while driving. Pop up on screen with a beep.

Unknown.

Fog lights go off and on by themselves at times. Forward collision warning continues to trigger and have to be reset. Automatic braking has engaged several times without reason.
