The 2010 Mercedes-Benz CLS passes its MOT at 79.2%, which is bang on the UK average of 80%—so reliability is roughly as expected for a 14-year-old premium saloon. However, 54.7% of these vehicles have recorded a dangerous defect at some point, which is significantly higher than typical and should give any buyer pause.

These cars are running at a median of 77,707 miles, which is reasonable for their age, but the real concern is the average of 3.25 failures and 19.8 advisories per test—pointing to a pattern of accumulating issues rather than catastrophic failures. Before committing to one, get a full pre-purchase inspection focusing on the suspension and electronics, as these are where the CLS typically racks up both advisory flags and costly repair bills.

The 2010 Mercedes Benz Cls has a decent first-time pass rate (79.2%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 19.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,480 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
