• Recall R/2017/124 [UK]: Faulty control unit may cause vehicle to perform outside specification
  Where a control unit coding was updated in a workshop between 3 december 2016 and 5 december 2016 the coding may not correspond to the specification and may trigger unplanned action in the vehicle. The safety and emissions systems may not react as design intent.
  recall the vehicles that are likely to be affected and update the software in the corresponding control units.

• Recall R/2011/172 [UK]: Fuel may leak
  Fuel leaks in the plug area of the drain opening may occur at the fuel filter with integrated fuel heaters. Fuel can escape and is noticeable to the customer due to a corresponding diesel odour. The diesel can reach the road and as a result friction between the tyres and road surface may be decreased.
  check filter and replace as necessary.

• Recall R/2020/243 [UK]: Engine control unit software to be updated
  Improve the vehicle emissions via software updates.
  update the relevant control unit?S software and if necessary replace the nox sensors.

• Recall 2018724 [Canada]: Steering
  On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (quebec, new brunswick, nova scotia, prince edward island, and newfoundland & labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. Correction: dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.

• Recall 2012401 [Canada]: Fuel supply
  On certain vehicles, the flange that attaches the fuel filter to the tank could eventually develop a crack and allow fuel to leak. Although any such leakage would be in an area where vehicle temperatures are too low for ignition, fuel leakage, in the presence of an external ignition source, could result in a fire causing property damage and/or personal injury. Correction: dealers will inspect and, if necessary, replace the fuel filter.
