See my post about the same problem on an '08 here: https://www.myjeepcompass.com/forums...1-compass.html
"....I've been getting quite a bit of torque steer (to the left on acceleration) and then to the right (upon the CVT changing the ratio once reaching cruising speed, or letting up on the gas quickly). Is anyone else experiencing something similar to this on an older, high-mileage Compass or Patriot?
I mean the car REALLY squirms back and forth under those conditions. Once at a steady speed / engine RPM, the car drives fine.
I'm assuming that it might be broken or tired engine mounts changing the geometry of the front suspension / axle shafts as the motor rotates farther than original factory specs. I'm not getting any kind of traditional engine "clunking" like you'd get on older rear-drive vehicles, so I'm suspecting that the new style mounts (oil filled) are just losing their strength when the engine is under load, and allowing the motor to move."
I've got good tires and struts, and both my front and rear sub-frames were replaced on Chrysler's dime.
According to the Jeep dealer, I may need one control arm (BOTH have been replaced twice already! Sheesh!), and while I'm sure I need an alignment (it pulls consistently to the left), that doesn't explain all the "squirming" the car's doing.
Please let me know if you find out the magic solution for your car, since it sounds SO much like my issue too!
