If it happens to your car, check your VIN for open recalls at nhtsa.gov/recalls and report the problem to NHTSA; complaints are what trigger investigations.
Check your own CLS-Class
Counts are a starting point, not a verdict: popular models collect more complaints because more of them are on the road, and NHTSA does not verify individual reports. To see whether a recall is still open on your car, enter your VIN at nhtsa.gov/recalls (U.S.) or your registration at check-vehicle-recalls.service.gov.uk (UK). Had a safety problem? Report it to NHTSA; complaints are what trigger investigations and recalls.
