1 of the 1 complaints (100%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors.

Keeping a Mercedes-Benz AMG CLS53 Reliable in Phoenix
Arizona heat is the hardest test a Mercedes-Benz will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a AMG CLS53 that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for AMG CLS53 owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Mercedes-Benz AMG CLS53, a pre-purchase inspection shows what the paperwork does not.
