Basic warranty on this car is 4 years / 50,000 miles. Only 26.3% of reported failures happen inside it — the remaining 73.7% come out of the owner's pocket. Powertrain cover (4 years / 50,000 miles) reaches further, but it only covers the engine and transmission, which account for about 7% of the complaints here.
What actually fails — and at what age
On the Mercedes-Benz CL-Class, the early trouble is Air Bags and Steering — reported at around 3.3 years, so a car still under warranty is the one to check for it. What waits further out is Suspension at 7.6 years — past every basic warranty, and the bill lands on whoever owns the car then.
