I had similar issues with the service center whereby the car was still drifting to the right even having done 2 consecutive alignment until my tyres were completely worn out. Needless to mention the type of kumho tyres that the ship the car with...
After changing to dunlop tyres and re-doing a wheel alignment i can say that it was finally fixed.
indeed...now the service advisor at the agency says this doesn't occur on the 5.7L version...total crap. overall an excellent car with all the builtin features and security. However the services cost and labor sucks!
is it the 3.6L? if so yeah..i've been told by the agency that it does jumps on the ODOmeter as the engine is too weak and makes a big roar. Really frustrating when u need immediate power.
