Criticism of the brightness of the instrument display on the 2012 facelift model.
Serious issues with piezo injectors of 220 CDIs cracking in later 2009. Many cars off the road for extended periods. Supply problems of replacement injectors, apparently made in Malaysia.
4-2-2011: Seems to be a widespread problem with automatic transmissions. MB is instructing dealers to replace the transmission valve control body, but there is a shortage of parts.
2-3-2011: Battery drains over about 2 weeks seems to be a problem.
27-8-2011: Problem of premature wear of timing chain sprocket for balancer shaft of M272 and M273 V6 petrol engines. Mercedes Star bulletin about this. Big job. Can cost £4,000.

22-5-2012: Paint problem after 4 years on front and rear bumpers of solid red painted examples.
23-5-2012: Yet another complaint of corroded alloys. Cou,d be that rusting of the steel wheel bolts is what causes the brown stains. Corroded wheel bolts is quite an old complaint, previously not thought significant enough to record.
16-7-2012: C350 has propensity to blow 477 H7 dipped beam bulbs.
7-9-2012: J ust after the 3 year warranty had expired, the steering column of a 2008 C220CDI had to be removed for worn or faulty 'bushes' to be replaced. MB met 95% of the £700 cost, most of which was labour. Automatic tranmission recently began sticking in 3rd gear and juddering or lurching at low speed. Repaired at a cost of £396.
14-9-2012: Strange problem of indicators flashing the wrong side. Might be due to moisture ingress to one of the side repeaters.

13-12-2013: Plastic interior door handles of W204 C Class seem to be breaking regularly. The first to fail is the drivers because it is the most used. Because these are an integral part of the door panel and not available separately, the cost to replace is £374 (inc VAT), plus fitting. Up to 75% is offered in 'Goodwill' in Germany. Nothing so far in the UK.
29-12-2013: Glycol contamination of automatic transmission fluid via the transmission heat exchanger can still sometimes occur, necessitatiing a new radiator and heat exchanger and flushing out and changing of ATF.

13-10-2010: MB is recalling around 85,000 Mercedes Benz C- and E-class models in the US to fix a problem with power steering systems, the US traffic authority NHTSA said. MB told Agence France Presse that the recall is likely to be extended to other countries. The NHTSA added that a problem with the steering system's pump could lead to a loss of fluid leading to a loss of power assistance when parking. Daimler stressed that drivers retained control of the car even in the event of a power steering failure. MB said it will fix the problem in 2010 and 2011 models this month by re-tightening a faulty fitting.
