While stoping at red light car stalls buckles dose not go over 50 mph as it hits 50 mph rpms go to6000 speed stays on 50 mph and I can't go on a high way cause I can't keep up with traffic noise coming from moter car got hot going up hills in 80 degree weather and it just all around runs like shit.

The contact owns a 2006 Ford Five Hundred. The contact stated that while driving 65 mph, the vehicle stalled with the illumination of the wrench warning lamp. The failure was experienced numerous times. The vehicle was taken to the dealer for diagnostic testing, which located the failure at the egr valve. The egr valve was replaced but the failure was not corrected. The vehicle continued to stall while driving. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 127,500 and the current mileage was 127, 6000.

5/20-7/18/11 car accelerated quickly and lurched backward with brake on while backing out of parking space; wrench light came on. Error codes were for alternative fuel control module and throttle actuator control system. Sometimes car lurched forward while braking, engine revved, car shuddered, and wrench and/or check engine light came on. Started happening almost daily. Very scary and unpredictable. Mass air flow sensor and egr valve were replaced. Had same issues 2 days later. Throttle body and vacuum hoses were replaced. Contacted Ford and they refused to cover parts and labor because car was no longer under warranty. Last repair was done 30 days ago and I've had no more problems, but it cost me $1600 to repair.

From the day I bought the car the a/c has not worked properly. It only cools at highway speeds or when temperature outside is less than 70 degrees, the engine has never idled smoothly and water collects in the doors. The main issue I've been having is that it surges at stop lights and totally shuts down going down the road. Motor, gauges everything shuts down sometimes for 8-10 seconds. This is sporadic and more common when the a/c is in use. I have had the throttle body cleaned and reprogramed several times with no change what so ever. I just had a new one installed and it shut down on me within 1 mile of dealership. It has been very frustrating to say the least. I've been saying it is something with the a/c since day one but all they wanted to do is replace the throttle body. I am at my wits end and just want it fixed!.

Since the day we purchased the vehicle, the gas mileage has always been well below the average for this vehicle. Combined city/highway has never exceeded 17 mpg and it had degraded to 12 mpg until the service department replaced a defective evap hose/fitting. The mpg returned to 17 mpg briefly but has since fallen off to 13 mpg. The dealership we bought vehicle from (champion Ford) has been unable to remedy.
