What should I look for in a used Mercedes E-Class saloon?
The previous generation of E-Class didn't do any favours to Mercedes' reputation for reliability. Thankfully, this newer model restores some of the good faith, but it's not perfect.
The automatic gearbox can be temperamental and, in the worst cases, owners could face a substantial replacement fee, while the largest diesel engine can suffer terminal issues with the injectors. There's also a possible problem with the camshaft position sensor, which could cause the car not to start.
Other concerns include noisy rear suspension, especially on Sport models. Not every car is affected and dealers can struggle to resolve the problem.
Some E-Class suffer mystery electrical issues, which can affect anything from the alarm to the parking sensors.
