GLC 300 was purchased new on May 25, 2023. Multiple 12V battery errors, check engine indicators, and rear hatch closing on owner starting the first week of ownership. 48V battery and Main Fuse Box were replaced. Multiple recalls were addressed. Most significant issue related to false collision avoidance incidents on two occasions that resulted in dangerous situations and extreme stress on the occupants. First occurrence was on July 12, 2024. Driving approximately 40 mph on two lane road near a school that was not in session. There were no surrounding vehicles, pedestrians or obstacles. Vehicle beeped, seatbelts locked, and speed forced to 10 mph. Took vehicle to local MB dealership who attributed the vehicle’s response to proximity to a school zone. Vehicle was not checked for fault codes. Second occurrence was on August 19, 2024. Driving 55 mph on major highway and a truck entered the merge lane to the right. The truck was travelling at reduced speed and remained in the merge lane showing no effort to merge into vehicle’s lane. Vehicle had violent sudden deceleration with beeping alerts, locking seatbelts and reduced speed to 10 mph. Driver and passenger experienced symptoms of whiplash. It was fortunate that there was no vehicle travelling immediately behind the vehicle. Vehicle was driven to MB dealership for analysis. The vehicle had been driven 6,177 miles in 15 months. Service manager indicated there were no fault codes so no maintenance was warranted. Owner viewed the vehicle as dangerous due to false collision avoidance issues that put passengers and others at risk. The owner sold the vehicle to the MB dealership.

On [XXX], I was driving at 45MPH on a two-lane state road. There was no traffic within 1/4 -1/2 mile of me on that road. There were no guardrails and the road was clear - no birds, animals, people, or construction. For no reason, the car beeped twice and automatically slammed on the brakes so forceful that everything on a seat landed on the floor. Had there been a vehicle behind me, they would have almost certainly slammed into me. This is my second safety report with this vehicle, the previously reported lane keeping assist still allows me to depart my lane with no correction or indication by the system, the dashboard indicators remain green if I depart my lane without a turn signal. It has been in 5 times for this and Mercedes closed the case. They say it's fine. Lemon law attorneys in my state refuse to take cases with Mercedes so I am stuck with a vehicle that should not be allowed on US roads, can't lemon law it and can't sell it or trade it in with a clear conscience. There is a laundry list of other problems as I drive more than 25,000 miles a year but I only report those which could get myself or others killed.

Brakes slammed on when passing a parked vehicle on side of road, causing following vehicle to almost rear end me. Following vehicle driver blew horn .I was driving at 45 mph speed limit with cruise control set and turn signal active to pass parked vehicle. Scary experience.
