Hi Folks, I am or was the "Proud" owner of a really nice glc43 amg. Bought it in march, had all services done, but had persistance engine performance issues. At oil change #2 the tech found that oil was being forced into and by the fuel injectors, rails and such, they spent 4 days replacing them, but never trouble shooted why? One day later the engine came apart so to speak, oil gushing by the fill hole, engine misfiring. The told me the following, cylinder #6 leak test was 80% leakage which caused overpreasre inside the engine? The scoped the #6 cylinder and found scoring and piston damage. The want to take off that head and repair it. It has 17000 miles on it. I asked what about all the metal shavings in the oil, the turo bearings oil coolers main bearing ect. They replied maybe it might need a new engine, but that is it, no new turbo's ot other parts. Seeing I am paying a note on this 70,000+ car I am a bit upset. Has anyone ever gotten a new car exchange or refund for such great failures? Friends say I will have to sue them, they just don't care will get it running and return it to me, damaged inside and all? If they replace only the engine other parts oil dependent could of been damaged too? Called corperate and I am awaiting there imput. Servive writers were rude when I stated some tec messed up, told me" Sounds like it's a personal problem of yours" here is a 38000 loaner till we fix this. The techs told me they have two other glc43's in the shop awaiting engines too? Takes 3 months to get an AMG engine from Germany they say. I was thinking they should get me a new on or refund my money? In any event any advice would be great. Last Mercedes I will buy for sure.
