There are 3 owner-reported visibility & wipers complaints for the 2020 Mercedes-Benz CLA-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving, the panoramic sunroof on my 2020 Mercedes-Benz CLA250 4MATIC shattered unexpectedly while fully closed. The interior sunshade was also closed at the time. There was no prior damage and no discernible impact. I did not observe or hear anything strike the vehicle. The fracture pattern shows no identifiable point of origin or impact and appears irregular and multi-directional, which is inconsistent with external debris. This appears to be a spontaneous tempered glass failure and raises safety concerns due to the risk of injury to occupants and driver distraction while operating the vehicle.
Front Windshield Wipers run randonly when they are not turned on manually. I would be driving and for no reason (no rain or water on the windshield) the wipers would come on and would not turn off when I used the switch. There was no warning message on my auto dash. It was startling and caused confusion when they came on unexpectantly. My mechanic shared a XENTRY document regarding this problem on 4/25/23. Copies of the XENTRY report and my repair receipt are attached.
