#1 of 5 Sudden acceleration by downie283

Oct 03, 2012 (10:52 am)

Yesterday, as I was exiting the interstate after a fairly lengthy drive at 75 m/hr, my 2011 Dodge Grand caravan kept accelerating as I tried to disengage the cruise control. It felt like the gas pedal was stoked down to the floor. Pressing hard on the brake pedal didn’t change anything and the engine kept revving up like made. I finally got the gas pedal to disengage after a few seconds.
The same problem happened one more times about 30 minutes later and a third time while the cruise control was not even turned ON.
Not sure if this is a Electronic Cruise control issue or a mechanical gas pedal problem. Has anyone experienced a similar problem in the past?

Hello downie283,
 
Sorry to hear you are having a concern with your 2011 Dodge Grand Caravan.
 
I checked for Technical Service Bulletins but could not find anything related to sudden acceleration as you described.
 
Please contact your local authorized Dodge Service Department so they can diagnose your vehicle.

I had similar experience with my 2009 Dodge Grand Caravan SXT. After a lengthy drive, both local and highway, my van kept accelerating even after the cruise control was off and my foot off gas pedal. I could not get the car to slow down except by tapping the brakes which caused the lightning bolt to appear on dashboard. I exited the highway and put the car in neutral. The RPM's roared & went all the way over to the left. At no time was my foot on the gas. I was able to park on a residential street & had the car towed to the dealer. The car has been there 3 days and they are unable to find any trouble.
 
Was your issue ever resolved?

Hi, Yes it would appear the issue is resolved. I reported the problem to my local Dodge dealer. They found the cause was a faulty "Accelerator pedal APP Sensor" which was replaced under warranty in November 2012. I have not had any further issues since.
Hope this helps with your problem as well.................. Cheers

Thank you. At first the service dept dealership said they could not find anything wrong and I could pick up the vehicle (I refused based on my experience); after an email to dealership general manager, the service dept replaced the "accelerator pedal APP sensor". Hopefully problem resolved but you can bet I will keep an eye on EDMUNDS should anything else go wrong. Thank you so much!
