Mazda recalls nearly 18,000 CX-5 SUVs for possible SCR system defect

Mazda has launched a recall of the CX-5 (KF) model with a diesel engine and all-wheel drive.

Due to insufficient wear resistance of the SCR system wiring harness and its special routing around the SCR tank cover, the wiring harness may become contaminated by sand or dirt. These contaminants can lead to severe wear of the wiring harness insulation due to the vibrations of the SCR tank cover.

According to the automaker’s report, in the worst-case scenario, the circuits in the wiring harness can be interrupted, and the MIL/SCR warning lights can illuminate. SCR (Selective Catalytic Reduction) is the exhaust treatment technology that uses Adblue to convert nitrogen oxides (NOx) into water vapour and nitrogen.

The recall covers 17,824 vehicles in Europe manufactured between 15 May 2018 and 24 September 2020.

The owners of the vehicles in question will be contacted by the manufacturer and asked to go to the workshop for repairs, where the wiring harness will be checked. If it is not damaged, a protective device will be fitted. If the wiring harness is already damaged, it is repaired and fitted with a protective device. The labour time required and the internal code is unknown when this article is published.

What the owner should do?

If you read about a recall that you think may affect your car, you should make immediate contact with a dealer or workshop that’s been officially authorised to perform repairs on behalf of the manufacturer and ask for the details.

If you wish to know more about eventual problems of a specific car (e.g. real mileage, potential traffic accidents damages, odometer rollback, repairs, etc.), then we suggest going to HPI-Check.
