We've been fortunate that nobody has been injured, but I don't believe someone should be hurt or worse before a company does the right thing and takes a proactive response to a known problem. It appears Toyota is not the only car company with sudden surges and/or problems with throttle problems. I've almost wrecked the car 3 times in our carport and parking lots as a result of sudden surge. I work as an insurance investigator and will ensure this problem is not overlooked. I asked if they communicated with each other to which I received an intelligeible response. I even offered to provide him the name and contact information for the other dealership, but was told they were in a "different district" and had a different reprsentative. I told him about the same problems with my 500 and the problems with the other company cars. The service rep acknowledged "some problems" with the throttle body, but advised it was not a problem in all vehicles. As a result and after the vehicle almost surged into our daughter, I took my wife's car to the Ford dealership today. The problem has gotten progressively worse. The vehicles were repaired out of warranty. Ford sent a representative to green Ford in greensboro, nc and diagnosed the problem as the electronic throttle body. Several other people with our company were also driving 500's and experienced the same problems. I began experiencing the same problems in/around the same mileage. But after my car warms up it runs fairly good, all though studder still exists.
I also had a 2007 model 500 as a company car. Im still in the process of fixing my car up, When I turn it on for the first time of the day, or after a long period after driving it, it ideals high, surges, and studders.
Since 40k miles, she's had continous problems with the vehicle surging at inappropriate times.
