Historical MOT pass rates and DVLA records for 2014 model year cars.
- 7G-DCT Gearbox JudderModerate
The dual-clutch automatic can become hesitant or jerky if clutch wear is present or fluid changes have been skipped.
- OM651 Diesel Timing Chain Tensioner Oil LeakModerate
The gasket on the timing chain tensioner is a frequent leak point. Oil loss can reduce tensioner pressure and lead to chain rattle and eventual stretch.
- Water ingress in boot from rear air vent sealsModerate
The rear air vent seals behind the bumper can fail, allowing water into the boot. This can damage the rear SAM electrical module, causing lighting and locking faults.
