What 36 owners told NHTSA about the 2021 Mercedes-benz GLS

Wipers - I have had repeated issues with the windshield wipers on this vehicle. I have taken it to the dealership 3 times and I have not gotten a satisfactory solution to the issue. The wipers skip across the windshield making intermittent wipers distracting. The dealer's service manager said this is a known issue caused by the OEM wiper blades. I've also been told they can't recommend a solution. AC - The AC in my 2021 GLS 450 smells like moldy socks which makes me suspect there is some build up on the coils or in the vent. I had the vehicle serviced 2 times at the dealership for this issue where the tech informed me the issue was not likely to be resolved by the $500 service I had paid for. The service was discounted down to $307.

Continuous malfunctioning front windshield wipers. In light to medium rain/wet condition the wipers chatter/jump on the windshield, leaving residue on windshield and causing substantial distraction to driving and even discourages use of wipers (leaving visibility poor). Mercedes Dearler/Service center has attempted multiple remedies over time but to no avail. Internet search of multiple forums on the web show many people with similar issues so thought it would be relevant for NHTSA to know. Issue is ongoing.
