Reliability & safety Rating

4.5 out of 5

Mercedes enjoys an upmarket image and a reputation for quality, but its customers aren't always delighted with their cars. The brand's recent performance in our annual Driver Power satisfaction survey has been lacklustre, but innovative technology makes the E-Class one of the safest cars on the road.

Mercedes E-Class reliability

The latest E-Class didn't feature in our Driver Power survey, but Mercedes could only manage a 28th-place finish overall in 2020 – just two from the bottom of the table. Around 17% of Mercedes owners reported one or more faults within the first 12 months, which was at least a slightly lower proportion than BMW and Audi owners. It will be especially galling to Mercedes that rivals Lexus topped the survey outright.


The Mercedes E-Class received the maximum five-star rating when it was independently tested by crash-safety experts Euro NCAP. A good result was expected, as the car is loaded with safety technology, including nine airbags as standard, as well as autonomous emergency braking and intelligent LED headlights.

The Driving Assist Plus pack (costing £1,700) adds Drive Pilot, cross traffic alert, evasive steering assist, active blind-spot assistance and lane-keeping assistance, among other features. The E-Class' autonomous drive mode was highly commended in the Best Autonomous Drive category at the 2016 Car Tech Awards, only finishing behind the Tesla Model S.
