“I started the engine and the power steering failure warning came on. True enough, it was a struggle to steer my car back home - I was just 3 minutes away from home. The car was towed the next morning to autohaus on edens in northbrook, il. I did a google search and found out that there has been a recall for this exact problem in europe since dec 2014. I was shocked that owners in the us were not warned of this potential problem and there has been no recall issued. …”
NHTSA complaint #10679748, filed 2015-01, 1,100 miles“The front drivers side suspension squeaks when wheel is turned or going over bumps. This car is less than 5 years old and around 50k miles. I am hopeful this is not a dangerous flaw in the suspension system.”
NHTSA complaint #11205909, filed 2019-05, 50,000 miles“Vibration at high speed around 70 m/h. Vibration during warm up after a cold start. Noise coming out from unknown parts possibly suspension when running over bumps at low speed around 7 m/h.”
NHTSA complaint #10705070, filed 2015-04, 1,000 miles“I took the car for annual maintenance to Mercedes-Benz dealership. After routine check up they came back to report rusty rear subframe and told me that needs to be replaced. However this part is really expensive and models from 2008 to 2015 C300 had the same issue(premature rust) and they all received extended warranty from Mercedes-Benz for free replacement. I wanted to report this safety issue for C300 model including mine that is not covered under extended warranty.”
NHTSA complaint #11656453, filed 2025-04“there is a recall for 2008-2015 Mercades Benz c-300 c/w204. this recall talks about the rear subframe rusting out early on this car. we have a 2015 c300 c/w205. this car is seeing the same early rust seen in the other c-300. the dealership is refusing to do right by the warranty because it is a c/w205 even thought this is a known problem for this year and type of car. I am making this because it should be extended to all c300 2008-2015 cause they all use the same subframe. they changed the subframes and the look of the c-300 starting in 2016. …”
