Euro NCAP awarded the EQA five stars for crash safety, but it's still a bit early to pronounce on long-term reliability

Mercedes has a very strong reputation for quality, and while there’s very little hard evidence just yet, we’d expect the EQA to follow suit when it comes to reliability. The brand’s smallest model, the A-Class, routinely performs well in customer satisfaction surveys like Driver Power.

It seems Mercedes owners are less happy with the brand overall, however – perhaps because they have particularly high expectations of such a premium brand. Overall, the maker finished a lowly 28th out of 30 manufacturers in the 2020 Driver Power survey – only Vauxhall and Dacia came out worse. Owners criticised their cars’ build quality, though black marks for running costs and fuel economy are clearly less relevant for the pure-electric EQA. Only time will tell whether EQ models like the EQA and EQC can turn around Mercedes' fortunes in this regard.

Mercedes EQA reliability & problems

It’s hard to drill particularly deep into the Mercedes EQA’s reliability as it’s a relatively new car. However, the maker’s decision to design its electric models around existing petrol, diesel and plug-in hybrid cars suggests at least some of the components should be dependable. Based on many of the same parts as the GLA – and therefore also the A-Class – the EQA should prove reliable.

The A-Class finished a respectable 36th in the 2020 Driver Power satisfaction survey, with owners particularly praising their cars’ infotainment, connectivity and electrics. Just 12.8% of owners had experienced problems, which is below average, though the model did finish in the bottom half for reliability and build quality. Being electric, the EQA has fewer moving parts than the A-Class or GLA, so in theory there is less to go wrong. High insurance costs might put some people off, however.


Euro NCAP decided in July 2021 to apply the Mercedes B-Class' five-star crash-test result from 2019 to the EQA, as the two cars are very similar under the metal. The individual section scores of 97% for adult occupant protection, 90% for child occupant protection and 75% for safety assist systems were carried over, too – meaning the EQA is a very safe choice indeed.

Every version comes with lane-keeping assistance, speed-limit assistance and blind-spot monitoring, plus LED headlights with automatic high beams. The Driving Assistance package is available across the range for £1,495 and adds things like adaptive cruise control, active speed-limit and steering assistance and active emergency stop assistance.
