Historical MOT pass rates and DVLA records for 2018 model year cars.
- Tyre Crabbing / Skipping (RHD Models)Moderate
Due to suspension geometry compromises for right-hand drive models, the front tyres can scrub, judder, or "crab" loudly on full lock, especially in cold or wet weather.
- AdBlue System / Heater FailureSerious
The AdBlue tank heater or pump frequently fails on diesel models, resulting in an engine management light and a countdown until the engine refuses to start.
- Electric Power Steering Rack Motor FailureSerious
The electric power-assisted steering rack on the X253 GLC integrates the torque sensor, control module, and electric motor directly onto the steering gear. When internal water ingress or electrical motor failure occurs, power steering assistance cuts out abruptly, rendering low-speed steering exceptionally heavy and logging diagnostic fault codes. Mercedes-Benz does not supply individual motors or sensors separately, necessitating a costly replacement of the entire steering rack assembly followed by factory wheel alignment and steering angle sensor calibration.
