Mercedes-Benz C-Class Coupe (2011–2016)

What to watch out for

12-6-2015: Warning at first MoT of a 2012 Mercedes-Benz C-Class coupe with just 9,000 miles that all four Continental tyres had suffered cracking on the sidewalls and between the treads. Dealer deeply disinterested, offering to replace the tyres at retail cost and submit the cracked carcasses to Continental.

7-2-2016: Strange problem reported on 2011/61 Mercedes-Benz C180 Coupe: The car has had from the start a problem with the ECO function. On the motorway the ECO function is on (green) for two minutes and then turns off (Amber) for one minute. This happens as regular as clockwork. The car has been in and out of the dealer now for months. They always change something and return the car assuring that it has been fixed (ECO battery change, various sensor changes). Yet within 10 minutes the fault returns.

14-2-2016: Upper bulkhead seam of 4 year old C-Class coupe split, leaking water into n/s footwell. Reader billed £1,500 for repair and refused to pay. Entered into MB complaints procedure but did not get car back.

12-12-2016: Report of red paint of 2011 Mercedes-Benz C180 Coupe starting to show raised pimples at 20,000 miles, despite regular cleaning and waxing.

29-12-2017: Owner started 14,500 mile 2014 Mercedes-Benz C63AMG (bought new in 2014) and "auto lights inoperative" came up on the dash display, even though lights were working fine. Owner decided to continue journey and call MB assistance when he got back home. During the journey he discovered that the windscreen wipers no longer worked on auto or manual. Once home he called MB assistance. Assistance arrived but following diagnostics and a software update this made the car worse - it would no longer start and run, with various other fault codes and lights now generated. Recovery was arranged for my car to be taken to Mercedes West Bromley the next day (19/12/17). Recovery arrived, even though he'd been informed the car wouldn't start he tried but battery had drained overnight, he then tried jump starting car to no avail and manually put the car on the low loader. Owner had call on 29-12-2017 informing him that car is 'ready for collection' following several days of no contact. On questioning it seems they're looking to charge just below £600 for 'Diagnostics and repair' inc replacement of a previously fine battery.

12-1-2018: Another problem reported with red paint on a 2013 Mercedes Benz C-Class Coupe, bought used from a BMW dealer. The paint blistered on it and Mercedes agreed to repaint the whole car. The blistering is returning again after only about 2 months.29-5-201

29-5-2018: Complaint of owner slicing hand open on driver's seatback release lever of 2012 Mercedes-Benz C-Class coupe. The hard plastic coating came away and sliced through his hand causing a 0.5 cm cut.

19-10-2018: Report of blisters appearing on the roof and back of 'Fire Opal" red used 2003/63 Mercedes C220 coupe.

30-4-2019: Report of 2015 Mercedes-Benz C-Class Coupe 2.2 C220CDi 7G-tronic stuck in gear and will not change up or down, speed is 25mph. AA Man Diagnosed Speed Sensor in the gear box. Towed to independent garage and awaiting visit by a Mercedes Benz engineer.

7-5-2019: Report of 46,000 mile 2015 Mercedes-Benz C220 CDi 7G-Tronic BlueEFFiCiENCY Auto AMG Sport Edition Coupe, purchased within 60 days, sticking in 1st gear, engine fault light showing. Initially the Speed Sensor was diagnosed as the cause. Subsequently diagnosed as faild servo valve in the Electro Hydraulic Valve Control Unit. Dealer procrastinating over liability. (See 30-4-2019.)

Recalls

23-7-2017: MB issued a voluntary recall to apply software upgrades to diesel engines in a bid to cut nitrogen oxide emissions on three million vehicles. All Euro 5 and Euro 6 standard diesel engines registered in Europe between January 2011 and September 2015 are affected. (Only the new two-litre turbodiesel fitted to the latest E-Class saloon and a new V6 turbodiesel in the soon-to-be released S-Class are exempt.) A Mercedes-Benz spokesman said that the “software upgrade” would be carried out by dealerships when customers visited for a service or other maintenance work and would take around an hour to complete. MB “did not expect” the upgrade to have any effect on the performance of Mercedes-Benz vehicles. Many Mercedes-Benz diesel vehicles have already had the update applied after work to apply the changes to compact vehicles and the V-Class MPV got underway in March. It was reported in The Times in July that while Daimler, which manufactures Mercedes-Benz, had not been found to use the same type of software for cheating emissions tests discovered in Volkswagen vehicles in 2015, it is the subject of an investigation by the German authorities into the possible manipulation of exhaust controls in cars with diesel engines.

17-10-2017: Mercedes-Benz issued a voluntary recall to apply a free-of-charge fix to approximately 400,000 UK models affected by a broken steering column spring. Coupled with insufficiently earthed wiring components, this may lead to a short circuit - which can inadvertently deploy the driver's airbag. If the airbag warning light appears on the dash customers are urged to contact a roadside assistance service or their nearest retailer. The safety recall affects certain A-Class, B-Class, C-Class and E-Class models, together with CLA, GLA and GLC vehicles, built between November 2011 and July 2017.
