On a daily basis, at low speeds, going forward or reverse, my car will surge or rev up when turning the steering wheel. Often times, it is when I am backing up and have the air conditioning on. It will surge and the brake has to be immediately pressed or the car will surge in the direction that you are traveling. This seems to be a common problem amongst 500 owners very similar to the Ford freestyle. This could easily lead to a fatality if the incident occurs at the correct time.

I was turning on to a road and when I went to accelerate the engine just revved up like it was in neutral. I have had this car in to bob boyd Ford 2 times because the transmission jerks but they have told me there is nothing wrong with the transmission. The first time I had it in there for the jerking they said it was the computer and it needed reset. I have done research on the internet and found other people having the same problems as me and I don't understand why this problem has not gotten a recall issued for these cars. I am going to take it in one more time but if they tell me there is nothing wrong again I will be pursuing legal help with getting a class action started. If the NHTSA is really concerned for peoples safety and well being they should look into the problems people are having with the transmissions in these cars. All I had to do was look up on google 2006 Ford 500 recalls and I found all kinds of complaints about the same problems.

Cvt transmission started making a "clicking" sound while in park, we took it in to our local dealer, they diagnosed it as under a tsb, but there were no parts available to fix it. So while we waited for the parts to be made (as we were told), the transmission went out as my wife and 7 month old child were driving it. So now I have a broken car with no parts available to fix it. Repeated calls and emails to Ford customer service had offered no solution.

2006 Ford 500. The car will suddenly surge at idle...it also surges during gear shifts from park to drive and park to reverse. If you do not have your foot firmly on the brake pedal the car will suddenly surge forward. This can lead to damage of the vehicle or injury to a pedestrian. Arfc website has 125 reports of this problem. Seems to get worse around the 60-65,000 mile range....conveniently out of warranty. Taking car to dealer today for evaluation and repair.

5/29/2009 transmission had to be replaced at 86,000 at a cost to me of $5197.36 total. Brand new Ford transmission installed warranty given of 3years 100,000miles. 6/21/2012 again transmission needs to be replaced at 150,000 4weeks after warranty expires. I understand Ford has had so many problems with thuis cvt that they stopped installing them. Ford dealer commented they have had to replace so many and are surprised a recall has not occurred. Very distraught that I am going through this again.

This Ford Five hundred surges or revs up the engine, in forward or reverse, when driving at slow speeds, usually into parking spaces or at red lights. This is a dangerous situation because we have no warning that it is about to happen. I have noticed it is worse if the A/C is on. We have avoided several accidents by slamming on the brake, it will even continue to surge if the brake pedal is held hard to the floor. The vehicle started doing this within the first 150 miles that we owned it. The incidents are unpredictable and dangerous.

- Longview , TX, USA

I was approaching a red light and as I lifted my foot off the brake pedal..............the car accelerated abruptly and I was unable to stop causing me to pass red light, almost striking an oncoming vehicle that was making a left hand turn and driving onto sidewalk. Fortunately no one was hurt and an accident was avoided due to my quick response. The vehicle has accelerated abruptly on several other occasions. I was parked in a publics parking lot when I put my vehicle in reverse the vehicle once again accelerated almost hitting parked vehicle behind me. I was advised the throttle sensor was defective on 2005 & 2006 Ford Five hundred models and no recall yet! this defect causes vehicle to accelerate abruptly (even when parked) or not accelerate at all! there have been many reports regarding this issue and nothing has been done about it. When a life is lost or someone is severely injured..................is that when some action will be taken? according to reports even if the part gets replaced it does not guarantee it will not go bad again. Repairs have been known to cost between $450 to $750.

I have a 2006 Ford Five hundred that will lunge forward at odd times especially when the A/C is on. It is a major problem and I believe should have been recalled a long time ago. I bought my Ford Five hundred in Jan 2008 and it has been doing it ever since. The dealer also replaced with used transmission and two weeks later that one was doing it. Problem started for me at about 45,000 mi. The dealer I purchased from said there was a bulletin out but no recall so I had to take the used transmission or buy a new one.it will just lunge forward even when braking or stopped. What a pain. I am amazed I haven't rear ended someone. Please recall this Ford before someone seriously gets hurt[xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I too have a 2006 Ford Five hundred that will lunge forward at odd times especially when the A/C is on. In fact, I won't even use the A/C anymore because of my Ford Five hundred lunging forward. It is a major problem and I believe should have been recalled a long time ago. I bought my Ford Five hundred in Jan 2006 and it has been doing it ever since. It will just lunge forward even when braking or stopped. What a pain. I am amazed I haven't rear ended someone. Please recall this Ford!

- Loveland, CO, USA

The vehicle will stall and jerk. The vehicle will lunge out even when the brake is pressed. It has done this in parking lots and while driving. This is dangerous as it almost caused an accident by jerking backward immediately when I shifted to reverse when I was in the parking lot- my foot was on the brake and the car still excelled.

Transmission failure, sudden loss of power. If you let the vehicle set or turn the vehicle off, sometimes you can regain some power to move forward but when you slow down and then try to increase your speed the vehicle will come to a complete stop.

- Indianapolis, IN, USA

My Ford Five hundred is losing power while driving down the street without warning. No car should be performing this way and no known mechanical issues. The car is driven daily and maintenance has been kept/up to date. I think this is an issue with this Ford model and year should be a recall on it.

- Memphis, TN, USA

The vehicles warning indicator light of a wrench lit up indicating transmission/throttle body service. Had previously had transmission inspected and were no problems. The car will thrust in direction car is in gear of such as when car is in reverse it will thrust and lunge backwards also in drive lunge forwards. It also is enhanced when the cars heater or A/C is running. Have researched and many, many people have had similar problems and complaints.

- Newark, OH, USA

My 2006 Ford Five hundred accelerates uncontrollably. When the car is shifted into gear it accelerates without throttling. It happens from park-to-any gear and sometimes when at traffic stops. I've noticed this problem for a while, but it is getting progressively worse. Scary!!!
