Got a specific Mercedes Benz Amg Cla 45 S 4matic+ Plus Auto you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

This 2023 AMG CLA 45 S is exceptionally reliable so far, with a 92.9% first-time pass rate that sits well above the UK average of 80%, and critically, zero vehicles in this cohort have ever recorded a dangerous defect. The car is clearly built to a high standard, which is exactly what you'd expect from Mercedes-AMG's performance engineering.

At a median mileage of 18,573 miles for a 2023 model, these cars are still very new and virtually trouble-free—averaging just 0.01 failures per vehicle and almost no advisories. If you're considering one, focus your pre-purchase inspection on service history and warranty coverage rather than worrying about reliability, since the real test will come once these machines rack up higher mileage and age beyond the current cohort.
