Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My vehicle is activating “crosswind assist” and applying the brakes automatically, unilaterally, and abruptly while traveling at speeds over 40 mph on the highway, even when conditions are NOT windy. It seems that the sensor is overactive in detecting wind. I have taken it to the Mercedes dealer and they have stated they found no problems with the ESP sensors and state that the vehicle is responding to perceived wind conditions/instability normally and as it should. However, this was NOT like this for the first two years I drove the vehicle. …”

Completed Recall and TSB Work Approved by Entegra and Jayco · 22-075 (TSB) A/C Electrical Connection Instructions, September 2022.

“Smog test failed California smog test due to the OBD 02 sensor (exhaust engine sensor) not being ready. Despite our efforts, including driving over 1000 miles and following Mercedes recommended drive cycle steps repeatedly, the issue persists. So far, we have contacted the Mercedes dealer several times, been told to drive the van around and given the Mercedes drive cycle instructions, but to no avail. Additionally, a customer case has been opened with Mercedes-Benz North America, only to be directed back to the dealership, where the vehicle remains with the unresolved issue.”

NHTSA complaint #11594217, filed 2024-06

“While driving in the freeway, the crosswind assist feature over-engaged and skewed the vehicle dangerously while also drastically slowing the vehicle and causing a hazardous near collision with the following vehicle. The system is way too aggressive and cannot be turned off or desensitized.”
