GLC300

  • 20 miles
The vehicle wonders within the lane when Mercedes distronic driver assistance is activated, particularly on gentle curves at highway speeds. It will hit lane bumps unless the driver actively steers away from the lane markings. The 2020 glc3004matic has been doing this since we purchased it new on January 2, 2020. Mercedes dealer has checked the vehicle and is now describing the vehicles behavior as normal. According to Mercedes this is a new driver assistance package in the 2020 glc. It is a major safety hazard if the vehicle is not actively controlled by the driver at all times. This is not an assistance package as described by Mercedes. We have driven older Mercedes with the distronic system that stayed in the lane vs. The wondering. We do not take our hands off the steering wheel the vehicle does this on it's own prior to any warnings related to driver awareness or actions. This action by the vehicle when distronic is activated will cause serious life threatening accidents.
