I have a 2008 Diesel Grand Cherokee, and bought it earlier this year, with about 225,000 km on it (in Canada). I'm having a string of issues with the vehicle - started as a strong burning smell, with smoke coming from the engine compartment. That lead to a replacement of the fuel injector rings, which revealed a lack of pressure (leading to a fuel pump replacement), and then upon testing, mixed error codes have now caused a replacement of the PCM. Anybody have any similar issues with these engines as they get into the 200,000 km range? This thing is bleeding me dry.
