Historical MOT pass rates and DVLA records for 2021 model year cars.
- Hybrid Battery / Charging BugsModerate
PHEV models can occasionally show charging faults or fail to engage electric mode due to software glitches.
- Frameless Door Glass Regulator & Microswitch StickingModerate
The frameless door windows must automatically index down 10mm when opening. Faulty door handle microswitches or regulator friction can cause the glass to catch against the roof weatherseal, causing seal tears and wind rush.
- M282 1.3L Turbo Electric Wastegate Actuator BindingSerious
On CLA 180 and CLA 200 petrol models, moisture and heat cycling can cause the electronic turbocharger wastegate actuator linkage to bind, triggering reduced engine power and an engine warning light.
