Historical MOT pass rates and DVLA records for 2020 model year cars.
- 7G-DCT Gearbox HesitationModerate
The 7G-DCT dual-clutch transmission in the X156 can develop clunky engagement, hesitation when pulling away, and shuddering during low-speed crawling. Software calibration issues and dirty transmission fluid exacerbate wear on the clutch friction plates and mechatronic hydraulic unit.
- Timing Chain Stretch (M270/M274 Engines)Serious
On 1.6-litre and 2.0-litre petrol models powered by the M270 turbocharged unit, premature timing chain stretch can develop. Stretched chains throw out valve timing synchronisation, leading to harsh cold-start rattles, loss of power, and potential valve-to-piston contact if ignored.
- 4MATIC Rear Differential and Haldex Coupling Bearing WearModerate
All-wheel-drive 4MATIC models utilize an electro-hydraulically controlled multi-disc clutch integrated into the rear differential. Operating on sealed oil that is rarely changed by owners, internal pinion bearings and clutches suffer from accelerated wear, causing droning whines and binding.
