Advice for buyers
What should I look for in a used Mercedes C-Class estate?
The Mercedes C-Class Estate has been subject to the following recalls -
A small number of vehicles built between 6 February 2019 and 12 February 2019 might have incorrectly fitted tie rods on the front suspension. If your car is affected, it will need to be checked over by a dealer, who'll rectify the issue for you.
Cracked lock nut
A lock nut used in the steering gear of some models made from 1 March 2015 and 31 October 2018 could be cracked, and will need to be inspected and replaced by a Mercedes dealer.
Electronic Stability Program (ESP)
A certain number of cars made from 1 June 2017 to 30 November 2018 have a software issue with the electronic stability program (ESP) that will need to be reprogrammed by a Mercedes dealer to ensure it works as intended.
The crankshaft fitted to a small number of engines installed in cars built from 1 February 2019 to 31 March 2019 could have surface damage that'll reduce its durability. Speak to a Mercedes dealer to find out if this applies to your car, because it will require a new engine if it does.
Engine wiring harness
A wiring harness in the engine bay might not have been installed correctly and any affected vehicles will need to have this checked out by a Mercedes dealer, who'll carry out any necessary repairs to prevent any future issues.
Front passenger airbag
There have been two recalls for the front passenger airbag. The first applies to C-Class models made between 1 August 2017 and 31 October 2018 regarding a software glitch that'll require an update at a dealer. The second is for a bad connector that could prevent the airbag from deploying in a collision on some pre-June 2018 cars.
This applies to the high-performance AMG models made between 1 June 2014 and 31 May 2016 where the rear axle mountings could break under extreme circumstances, such as full acceleration on a wet surface or when repeatedly breaking traction of the rear wheels. If your car is affected, it'll need to have some software updates applied by a Mercedes dealer to the ESP and electronic chassis control units to limit performance during such scenarios.
There have been three recalls to the power steering of the C-Class. First is the motor itself that can fail on models built between 1 August 2014 and 31 December 2016 and will need to be replaced. Then there was a software problem on some cars built from 1 November 2017 and 30 April 2018 that require an update. Finally, there is a sensor issue in the system of examples manufactured between 1 July 2018 and 31 August 2018 that could fail. Speak to your Mercedes dealer who'll be able to say if any of these applies to your car.
There has been an issue found with the driver's airbag of some cars made from 1 January 2018 and 30 March 2018 where the bag itself won't perform as intended in a collision. Your dealer will be able to find out if this applies to your car.
Rear beltline trim
The rear beltline trim on the exterior of examples manufactured from 1 January 2016 and 30 November 2017 can come loose, and will need to be inspected at a Mercedes dealer to determine if it needs replacing.
Front seatbelt pre-tensioners
Both the left and right front seats of cars made between 1 April 2016 and 31 March 2017 have been found to be faulty, meaning that front seat occupants aren't restrained correctly in a collision. Find out from a dealer if yours is affected and have the pre-tensioners replaced.
