Unintended Acceleration

packsail · February 27, 2014

I pulled out of a parking lot on to a city street and pressed the gas pedal a little, planning to get up to about 25 mph because there was a red light a block away. The truck responded as if I had floored the pedal. I took my foot off of the pedal and the truck kept accelerating at full throttle. I hit the brakes thinking the cruise control had gone nuts, BUT hitting the brakes would NOT turn it off. It kept accelerating with the tach over 5000. I shifted to Neutral and the engine speed dropped down to idle.

The light turned Green and I shifted back to Drive and the engine immediately started accelerating again at full throttle. I put it back in Neutral, moved over to the shoulder and turned the key off. Then I started the engine again and the problem disappeared. I'm 72; if my wife had been driving by herself, she probably would have had a serious wreck. The truck is a 2014 Silverado, bought 4 weeks ago, 6 cylinder work truck. Anybody else had this experience?

Wow, not good. Notify the dealer immediately! Something has obviously malfunctioned. I would suggest not driving it until the problem is fixed.

I agree Tom. Call the selling dealer or GM's Free Roadside Assistance # in the back of your owners manual soon!!

Something is very wrong with your new truck. Please post back the dealer's findings at a later date.

I had PM from the OP.

The dealer called me this morning and said my truck was ready to be picked up. They said that they could not duplicate the problem and there was nothing they could do.

P.S. It's not Spam as some are accusing me of.

I don't know how to navigate through this website.

Cut OP some slack. I believe he had some kind of problem. At least he has it on the record with GM. He'll contact GM Customer Service via PM to see if they can offer any further insight.

You can discuss the issue but further posts calling it spam or BS will be deleted at this point

All other issues with these trucks have been verified. Only ONE unintended acceleration on record anywhere to date. If more arise on legitimate sites, no doubt there may be an issue. A PM to a mod does not make this gospel, though. We've seen entirely too many of these type posts to put much faith or merit in them at this point. For the OP's sake, if legitimate, I hope they can find the cause of said issue which he described.

Operator error? Anyway to have the dealer reflash the ECM? What type of floor mats do you have?

We had a 2013 do something similar, but the driver simply shut the key off and pulled over. Restarted and the problem never re-occurred, but the dealer also swapped TB and ECM. So don't know what the problem was for sure

I went in to pick up my truck and told the Service Manager that he should take my truck back and give me another one, just like mine, but without the transmission and unintended acceleration problems. He said he would discuss that with the Sales Manager and let me know. I'm still waiting.

I hope they take care of you.. That is a very scary thing to happen. Unless they just flat out don't believe you they should replace it just on the basis that if it happens again, you could probably sue them, now that you have taken it in for this. Especially if you have an accident because of it.. I like the guy above have seen a vehicle do something very similar to this, but again like the guy above the person just turned the key off right away and of course it stopped.

Since you went to pick it up, what were the dealers findings in relation to your claim?

I have been waiting for a reply from the Dealer. A few minutes ago, the Owner, Mike Hewlett of Hewlett Chevrolet, called me. He said that they want to give me a loaner truck just like mine and have the service manager drive mine every day for weeks or months to see if he can duplicate either of my two problems.
