Engine light is on and vehicle is sluggish on hills and keeping up in traffic. Rpms run high if I try. Error code p0299 shows on scanning device- turbo under boost. I have 112,000 miles and need turbo replaced already. this vehicle is very well maintained. I did see a special notice for the GX version of this vehicle. But dealer says my vin does not qualify
