Mercedes EQC review - Reliability and safety

The EQC offers excellent safety credentials, while reliability shouldn’t be an issue.

The EQC is relatively new, but shares much of its architecture with the combustion-engined GLC, so we’d expect this to count towards it being reasonably reliable. 

Equally, the EQC hasn’t been around long enough to feature in our latest Driver Power customer satisfaction survey, but Mercedes itself showed signs of improvement, coming 13th out of 29 manufacturers – far better than 28th-place out of 30 manufacturers in the 2020 poll. Customers cited high running costs as a key issue, while the infotainment systems could also be better.

Safety equipment is impressive across the range with Parking Assist, a rear camera, Active Brake Assist, lane departure warning, a blind-spot assist system and cruise control all offered as standard.

Euro NCAP tested the EQC in 2019 and awarded the all-electric SUV a full five-star rating. Individual category scores were outstanding with 96% for adult occupant safety and 90% for child occupant protection. Safety Assist technology was rated at 75%.


Mercedes offers a standard three-year/unlimited-mileage warranty for all its new cars. The EQC’s batteries carry warranty cover for eight years, during which time Mercedes will also replace or refurbish the lithium-ion batteries if they fall below 70% of their as-new performance.

The manufacturer also offers a bespoke EQC warranty extension for up to 6 years, helping to protect against unexpected repair costs. The warranty extension covers most mechanical, electrical and electronic components.


Servicing intervals for the EQC are annually or every 15,000 miles – whichever comes first.
