Mercedes-Benz CLS-Class reliability by year
Each year is complaints filed in that year’s first 3 years on the road, divided by however many of those years have passed. A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market Mercedes-Benz CLS-Class. How we count.

Known issues for this generation
Recall 19V-605 covers certain 2019 CLS 450 Coupe and CLS 450 Coupe 4MATIC vehicles with 6-cylinder gasoline engines: the electrical line that supplies power to the engine coolant pump may contact the engine fan and chafe, which can cause a coolant-pump malfunction or a deactivation that may lead to overheating. Dealers inspect the coolant pump electrical line for damage, then repair and reroute it as necessary. Recall 18V-911 covers certain 2019 CLS450, CLS450 4MATIC, and CLS53 AMG vehicles: the horizontal headlight adjustment screw may not be effectively sealed, allowing improper headlight aim; dealers inspect and seal the screws as necessary.
