The vehicle suffers from severe, persistent electrical and powertrain failures that compromise safe operation. Multiple Advanced Driver Assistance Systems (ADAS) have completely failed, including the Lane Keeping Assistance, Blind Spot Warning, and Forward Collision Warning systems.When driving, the vehicle constantly flashes erratic dashboard warning messages and emits continuous warning chimes without cause. In addition to the electrical failures, the powertrain malfunctions; the vehicle jolts violently upon acceleration, behaving as though the transmission is failing.Safety Risks: These failures create immediate safety hazards. The unexpected transmission jolts cause unpredictable acceleration when merging or stepping on the gas. The loss of forward collision and blind spot warnings leaves me without critical safety buffers, and the constant flashing lights and beeping create a severe driver distraction.Inspection and Diagnosis: The vehicle has been taken to an authorized dealership service center multiple times for these specific issues. However, the service department has refused to properly document the complaints on the repair orders or perform standard diagnostics, falsely claiming the safety sensors are just "dirty" and blaming the transmission behavior on driver habits. The vehicle and its malfunctioning components remain fully available for inspection.Onset: These symptoms first appeared shortly after purchasing the vehicle and have grown progressively worse.

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...

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."

Vehicle started show MULTIPLE errors on dash from blind spot not working , lane assist not working, AEB need to be checked,rear brake light not working, turn signal not work, lane assist not working and other errors. Went to dealership for these errors where they repaired a faulty sensor on the front for the lane assist and from collision. Said it was fixed...It was not. Within a hour leaving the dealership, if you pressed to turn off the power save button for when the vehicle when it comes to a stop and not idle, the errors all pop up one after another.. they did not correct any of the errors. I check back lighting and they are on and working but errors say they aren't. Front collison day is it not on but it works and alarms a sound. This is dangerous and if it will have dangerous outcome given it would not correct. Also was receiving notification.to pay into a program for future problem the moment it started again (i paid for extra coverage at signing) I don't know if it's electrical, auto start stop, the lights or something else. Car is barely 2 years old with less than 10,000 mi on it (straight for dealership). Dealership do not clear codes or correct the errors no matter me mentioning them to them.

This car has stalled 9 times while I was driving. I live in a very busy, densely populated area where car stalling in the middle of streets can get me badly injured or killed. The car stalls in Drive, while I'm braking, and slowly coasts along about an extra 2 feet before completely stopping. I cannot tell that it has stalled because I can't hear the engine, and the Dash always says "Run" with all the lights lit up. Also, Lane Assistance comes on when no cars are around and the car just starts braking on its own and slows down with loud bells ringing and flashing lights on the inside of the car. I turned Lane Assistance off, but it stills comes on by itself. I'm afraid to drive it, but it's all I have and in this city you need a car to get around because nothing is close to home.

I purchased a brand new 2025 Jeep Compass Latitude, and shortly after, I started getting repeated error messages for several safety features, lane departure unavailable, blind spot monitoring unavailable, auto high beam unavailable, and automatic emergency braking unavailable. These warnings appear randomly: sometimes as soon as I start driving, other times 5–10 minutes later, or even after 30 minutes to an hour of driving. There’s no consistent pattern, and when they activate, all the affected systems stop functioning until I restart the vehicle. I’ve taken the vehicle to the dealership three times for this issue. The first time, I was told there was nothing they could do because no active code showed at that moment. The second time, they said they couldn’t look at it because they had no loaner available. The third time, I left it for nearly two weeks. They said they test-drove it, the error never came on, and that Jeep engineers have acknowledged this is a known issue with some Jeep and Dodge models. I was told there may eventually be a recall or software update, possibly within a year, but no fix is available right now. I don’t feel safe driving a new vehicle with unreliable safety features that turn off unexpectedly and can’t be repaired. I rely on these systems for highway and night driving, and it’s unsettling that the dealer and manufacturer both admit to an issue but expect me to continue driving and just wait for a future update.

A few weeks are I bought the car, it started having sensor issues. It would tell me that my brake lights are out, my lane assist is not available, my turn signals are not available, etc. After spending weeks at the mechanics, the dealership gave me the car back and said that everything was fine. A week later, all of the sensors started messing up again one of the sensors that was messing up was the auto brake system. As I was driving on the highway at 75 mph, the car thought that I was about to hit another car. There were no cars around to activate this auto braking system, but the car slammed on the brakes in the middle of the highway. It spent another few weeks with the dealership mechanics and is now having the same issues.

When driving the car will randomly active automatic emergency braking, which is especially dangerous on the highway. Lane departure has pulled me to the wrong lane, or will randomly become unavailable. Blind spot monitoring occasionally doesn’t work, or will also randomly become unavailable. Dealership made aware but unable to recreate circumstances in which they become unavailable or faulty. There are never prior warnings, this will happen whenever. There are multiple other ‘24 Jeep Compass owners who report the same issue online.

I am having a persistent issue with this vehicle involving the lane keep assist and pedestrian collision sensor. This issue has been present since purchasing the vehicle in December of 2021. I have had it in to two separate dealers a total of 6 times with no solution yet. The issue occurs when traveling down the road above 35 with the active lane assist enabled. Intermittently the vehicle will act as if there is a significant steering misalignment and the vehicle will attempt to pull you out of your lane into other lanes and you have to fight the steering assist in order to not depart your lane. Some times with the issue the car will throw a code stating "Active Lane Management (ALM) Unavailable Service Required" and turn the ALM off. The dash light will stay illuminated until the next key cycle and then disappear. The other issue with this system occurs when taking a 90 degree turn. The vehicle will throw the same error message and turn off the ALM and intermittently with also disable the pedestrian collision avoidance system which will remain off until I go into the settings and turn it back on. The dealerships have replaced the BCM, Steering Wheel, and Steering Wheel control module. There have been no actual solutions provided and this issue remains active. I do not want this to cause an accident one day when the issue occurs and the driver is unable to correct the vehicles mistake.
