There are 2 owner-reported driver assist & adas complaints for the 2022 Mercedes-Benz GLS-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Car has been auto braking even though there is nothing in front of the car. This is extremely dangerous and could lead to serious rear end collisions. There are many similar complaints on online forums and Mercedes (and their lawyers) do nothing.

When coming into the proximity of devices along the highway that transmit radio/communication signals, message appears with several indicator symbols illuminated, “Temporarily Unavailable-Sensors are Dirty”. None of the ADAS functions work until you stop and restart the engine, or sometimes will return in a few 3-5 minutes or it may be an hour if you don’t restart the car. The dealer is aware this is a problem with Merc Benz but has no solution. Besides being a nuisance this can be very dangerous if assuming systems are working.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
