“I have been experiencing failures from my speed control. It moves slow on it own regardless of how high the meter says. When braking the car shakes and then on its own it goes off and all the lights on the dashboard comes on. This has happened to me 3 times on the highway. The engine light also came on recently and now my car vibrates/ shakes when idle or when it starts.”

The tires are awful the suspension is even worse then my air bag light cut on out of nowhere and now my steering column is totally messed up. Directly behind the airbag. It clacks back n forth as you move the steering wheel even ever so slightly. …”
