The components of the engine being the camshaft adjusters, timing guide, timing chain, valves and pistons that all work to deliver power are faulty and have failed literally mid-drive. I was on a busy interstate during rush hour and nearly lost control of the vehicle as it just powered out while driving at 70 mph then forcing a semi to nearly terminate myself and family. The dependability and safety is abruptly ripped out from underneath you. Without even being able to control the vehicle and it coming to an abrupt, unsafe hault. There were no warning signs. The vehicle has since been looked at and informed me that an extended warranty is in place for half of all the parts and labor above.all should be covered and for safety.my nerves are a wreck and without a way to afford an entirely new engine I am left to contend with car payments for an unsafe undrivable vehicle. Since then the dealership recognized my concerns but has since stated that without a modification to the extended warranty or it being made a recall that there is nothing that can be done.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2013 Mercedes-benz C-class Phev verdict →
