There are 1 owner-reported powertrain & transmission complaints for the 2017 Mercedes-Benz SL-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
When pulling into an intersection after stopping at a 3-way stop the car unexpectedly went into neutral gear. An oncoming car had to stop suddenly to avoid a collision. I was able to shift the car back to drive and got it home. Now the car will not start and there's a warning message on the dash saying to get the car to a dealer. The car is now at the Mercedes dealer. Apparently the problem exists on other Mercedes models.
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.
