Warning message in dash stating that the drive mode is unavailable. Emergency and safety features are not functioning as they should. The emergency braking and forward collision warning doesn’t work. When driving, the warnings will go off independently and disengage. Byers Chrysler Jeep Dodge Ram dealership in Columbus serviced the vehicle May 2026-August 2026 with support from Stellantis replaced multiple components and the harness to repair the drive system, with all failed attempts to correct the problem. On August 10, 2026 the dealership returned my car to me, citing no repair available and that a software update should correct the issue. Dealership advises the car is safe to operate.

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.

I am reporting a severe, life-threatening safety defect involving intermittent "phantom braking" (unwarranted activation of the Automatic Emergency Braking / AEB system) on my 2024 Jeep Compass while driving at highway speeds. On multiple occasions while traveling on the freeway, the vehicle has suddenly and aggressively slammed on the brakes with absolutely no obstacles, vehicles, or hazards in front of it. The vehicle anchors the brakes without warning, causing rapid and dangerous deceleration from 60-70 mph. This has nearly resulted in catastrophic rear-end collisions from vehicles traveling behind me. The issue is highly intermittent and unpredictable. It appears to be a major defect in the Advanced Driver Assistance Systems (ADAS)—specifically the forward-facing camera or radar modules—which are misinterpreting road conditions, shadows, or reflections as an imminent collision threat. We have actively tried to get this resolved through the Classic Jeep, Madison ohio. The vehicle has been brought into the dealership service department several times for this exact occurrence. A corporate safety "SAFE case" was opened CN102930576 , and most recently, the customer service manager test-drove the vehicle for 4 to 5 days. Because the issue is intermittent, they were unable to replicate it during that specific timeframe, found no active error codes in the computer, and performed no repairs. The vehicle was returned to us completely unresolved and remains an active danger to drive. The manufacturer's inability to replicate a highly intermittent software or sensor defect does not negate the severe danger this vehicle poses. Sudden, unprompted hard braking at 65+ mph creates an immediate risk of a multi-car highway accident. I am filing this complaint to urge the federal safety agency to investigate 2024 Jeep Compass forward collision warning and AEB systems before this defect causes a serious or fatal crash.

I am filing a formal safety defect report regarding a severe, non-functional Advanced Passenger/Pedestrian Emergency Braking (PEB) and Forward Collision Warning (FCW) system that has been completely inoperable ("INOP") since delivery of this brand-new vehicle.The vehicle has been subjected to four (4) independent, consecutive service repair attempts at authorized franchise dealerships with a complete failure to resolve the active safety hazard.Critical Evidence of Manufacturer Negligence: Corporate Techline Admission: On 12/2/24 (3,327 miles), factory technicians performed module updates but noted on the official invoice: "Issue persist. Contact Techline was told update coming." Corporate engineering knowingly discharged a defective vehicle back into public operation without a functioning collision avoidance system.Star Engineering Admission: On 5/15/26 (34,461 miles), following extensive factory hardware resets via the wiTECH diagnostic network and manual sensor/camera recalibrations, the safety defect persisted. Stellantis Corporate Engineering (Star Agent) explicitly ordered the dealership techs to return the malfunctioning vehicle to the consumer because it lacked an active Diagnostic Trouble Code (DTC), stating the safety hazard was merely "currently under investigation."Current Grounded Status: On 6/8/26 (approx 36,000 miles), Certified technicians determined an instrument cluster needed ordered and legally "grounded" the vehicle on the dealer lot due to federal odometer rules. The vehicle is currently sidelined awaiting a backordered instrument panel cluster (IPC). Public Safety Impact: Stellantis is willfully ignoring a widespread component or software defect in its integrated digital instrument cluster and forward-facing camera arrays. By ordering dealerships to return vehicles with dead pedestrian emergency braking systems to consumers due to a lack of DTC’s, they are creating an immediate, severe hazard to occupants and pedestrians on public roads

The adaptive cruise, automatic emergency braking, and forward collision warning turns off randomly and the warning lights come on saying they are not working and to take it to the dealership. This has happened around 8 to 10 times. The first being under 1000 miles. I took it to the dealership then and they said nothing was wrong and I need to keep the sensors clean. It makes no difference if the car is just washed or dirty. I’ll be driving on a city street or highway and all of a sudden the warning lights are on. Sometimes they go off by themselves. Sometimes after I turn off the car they are on but when restarted they are off. Finally tonight about 5:45 on the highway multiple warning lights went on. Engine, all safety warnings, transmission warning, overheating warning. I pull over and all the transmission fluid began to pour out onto the highway. I had to pay 178.00 and wait on the shoulder of a two lane highway for about an hour and a half before the tow truck arrived. I had it left at the dealership and had to pay 80.00 to get a Lyft to my house an hour and 25 minutes away. I will find out tomorrow about the transmission failing but they won’t do anything about the other safety systems going off at random.

Driving the vehicle under normal conditions and no obstacles in the vicinity, the forward collision warning will engage and in some instances cause automatic breaking causing temporary loss of control. Sensors are clean, software appears up to date.

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!

Note: The vehicle is totaled, and GEICO Insurance is in possession. A month ago, we received Brake warnings. We brought the vehicle to a mechanic to get checked and it passed. We did not get the warning again. 2 weeks ago, while turning into our driveway, as we were almost stopped, but still in the turn, the vehicle made a noise similar to the Auto Stop/Start feature. The power brakes and steering stopped working (everything was stiff). The car accelerated, and we hit the corner of our garage (because we did not complete the turn into the driveway). The vehicle then hit a tree where it came to rest. The collision avoidance, didn't kick in. Unsure about the final speed of the vehicle, but it was fast enough to deploy the airbags and total the vehicle. There is a police report with the Closter, NJ Police.
