| Service Brakes problems |
My car has experienced unintended automatic emergency braking while driving in active traffic with no obstruction present. This created a serious risk of a rear-end collision from vehicles behind. Prior to this, the car had ongoing alignment and steering issues beginning shortly after purchase. The car consistently pulls while driving and has required multiple repair attempts, including alignments and inspections of steering and suspension components. These repairs have not resolved the issue. The problem appears to be worsening. In addition to the unintended braking, the vehicle intermittently displays safety system warnings related to driver assistance features. The failure involves both mechanical and electronic systems, including steering alignment and automatic emergency braking. It's believed that incorrect alignment or suspension issues may be affecting sensor calibration and causing false collision detection. The car has been inspected multiple times by the dealership, but the issue has not been diagnosed or permanently repaired. The car's unsafe to operate due to unpredictable braking behavior. The warning signs that the car gives are “traffic jam assist unavailable” and “safety system malfunction” while driving. These warning messages and system malfunctions have been occurring intermittently since shortly after purchase in early 2025 and were previously reported to the dealership. The warnings continued after the incident and are documented with photos taken the following day. The safety systems appear to be unreliable and malfunctioning in real-time operation.
On March 10, 2024 we were parking the car in the lot at 3450 montgomery rd, aurora, IL 60504, when the car suddenly accelerated despite my foot being on the brake and crashed into a storefront. The fireman said the airbags deploy code was issues but the airbag never deployed, and the automatic emergency braking did not stop the car. It seemed as though the transmission was switched, but we had not touched the gas.
While overtaking another car on a 2 lane road under high acceleration (90 mph) it appeared that all electronic systems in the car failed. The display showed several systems failing after another and beeping indicators were heard. The power breaking failed, only non-power assisted breaking, power steering failed and the engine stalled during the time while overtaking another car. I could still overtake the other vehicle and was able stop the car on the side of the road. When parking I shut off the ignition, started and was able to continue. The same issue happened later on that day. Then after that event the sos malfuction warning came on as well as the engine orange led (see picture). This had no direct effect on driving and this warning stayed on for about a week. Suddenly that warning disappeared.
Front brakes engaged while driving without warning. Rear brakes ok. Front brakes overheated before I could safely stop. Smoke from front brakes evidenced the overheating. Towed to dealership who could not duplicate the problem.
