Vehicle began losing power upon acceleration. At one point it got so bad the vehicle didn't move with accelerator pressed to the floor. Brought to dealership and was told that the lines going to the turbos were clogged and it would be my responsibility to fix. I asked how they found the problem and they stated they had to drop the engine. I told them that they did all my maintenance, was it something they checked regularly? They said no. Then it won't be my problem because if you don't drop my engine to check for each time, why would I? They stated that because I had records of all my regular oil changes and maintenance that it would be covered by the warranty. I still can't believe they tried to blame us for an obvious malfunction. The turbos are that sensitive that they completely need to be replaced within the first 50-60 thousand miles?
