Spoon Sports 11/11/2011If the car pulls while driving at a constant speed on a straight flat road, then you either have a tire inflation problem, mismatched, or defective tires, an alignment problem, or possibly a sticking brake caliper.
A slight pull under heavy acceleration on a front wheel drive car may be normal. This is called "torque steer" and is caused because the front drive axles are not the exact same length (not a defect, just a fact with most FWD designs) The transmission is not located in the exact center of the car, and on axle must be longer than the other. This causes a pull under hard acceleration!
If you have a brake problem, it could also cause the car to pull when the brakes are applied.
Check the tires for obvious problems and correct inflation. If they seem ok, have the car checked by a qualified mechanic.
