Unexpected Acceleration

HI FOLKS
YESTERDAY WHILE STOPPED AT A LIGHT MY 2003 SSR TRIED TO TAKE OFF ON IT'S OWN, WHILE MY FOOT WAS ON THE BRAKE. SHE BURNED RUBBER IT TRIED TO MAX THE POWER, TO AVOID AN ACCIDENT I SWITCHED OFF THE ENGINE.
I TURNED THE CAR BACK ON AND THE PROBLEM WAS GONE , FOR NOW!!
IS THIS A NEW FEATURE ADDED?

Do you think you may have had part of your foot on the gas pedal?

OMG you know this happened to me once also. I thought I might have double footed the brake and the gas at the same time. You are SURE you didnt do that? Also I think I remember a thread in my Jeep forum where that happened and the cause was a slipped floor mat?? I sure hope its driver error and not the Truck. Are we drive by wire like the Corvette?

I thought this only happens to people who are 80+ years old.

I'm no techie, but I do believe our trucks are drive by wire.

Thank God you were able to catch it and are okay.

WOW I'm not so sure I want to hear this. Let's hope this isn't a hidden problem.
Hasn't happened to my 04 and hope it never does.

I don't know, this is only speculation but in all of the years I've worked on cars and worked with electricity I can see this kind of problem with this relatively new technology. Electrical spikes can burn out bulbs, cause wires to overheat enough to burn off the insulation of wires. I'm again speculating but I would think the accelerator works somewhat on a reastat theory. If so then a power spike could easily cause what you describe. Also as people know that use computers, an electronic operation by wire device, unexplanable S*&T happens.

Didn't Jeep Cherokees or Explorers or some car like that have an issue with the cruise control engaging out of nowhere and doing this? Never had this problem, hope it's not wide-spread. Glad you're OK!

I strongly suspect that this is a case of driver error. I believe that there is just one way this can happen..hit the wrong pedal. This issue has been extensively researched. The conclusions arrived at by the auto manufacturers and by , I believe, the NHTSA, are that it was always the result of driver error. The cars involved never had any identifiable mechanical problem when they were examined. Cars with pedals positioned more closely together were more likely to be involved in these incidents, and elderly drivers were more likely to be involved than younger drivers. Another clue that driver error is the culprit is that it only ever seems to happen on automatic cars.

I never had this happen in any of my C5s. BUT this same thing did happen in the SSR like the second week I had it when pulling into my driveway. I put the shift in N and the truck went back down to normal and I just figured It was my fault because my feet are so wide. Of course if you are double peddling the harder you think you are tromping on the brake you are also doing the same to the gas pedal. I do remember being somewhat in shock when it happened and just glad I didnt crash into my garage door. I just figured I was at fault now im a little bit scared to hear it happened to someone else.

Keep in mind that CoronaDan said he was STOPPED at a signal with his foot ALREADY on the brake when it not only surged ahead but began burning rubber. Doesn't sound like driver error to me.
Also, it is obvious that this only happens on automatic cars since it would be (nearly) impossible with your foot on the clutch.

Impossible IMHO

If the driver's foot is firmly planted on the brake it is virtually impossible for the wheels to spin. You would have to have 2 failures at the same time...brakes and throttle. The engine is not going to overpower the brake system...not gonna happen.

Your humble opinion makes good sense.

This indeed is very true.

The incidents are ALWAYS driver error. His recollection does not match what actually happened, same as with all such cases where drivers report runaway cars but mysteriously, in EVERY case, no malfunction can be found.

His recollection of events cannot be relied upon because he obviously didn't realize that he was standing on the gas at the time.

Yes, it would be impossible for driver error to cause a stick shift car to run away, that was my point, this proving the point that it was driver error.

My wife experienced a similar event when parking her 2004 Thunderbird in the garage one evening (shortly after buying it). The T-Bird has EXTREMELY close gas and brake pedals. She at first thought the car "did it by itself" but after we discussed the issue and she showed me where she placed her foot, she even agreed that it was her doing and not the car.

Not to say that a drive-by-wire system cannot be the source of this type of problem, but "most" of the time it's the human involved in the situation.

The one "by wire" system I'm just not ready for, call me old if you want, is steering-by-wire. Not having direct control over where the front wheels are pointing seems real scary to me.

I'm just glad to hear that CoronaDan had the presence of mind to take corrective action when it occurred.

It could be due to a floor mat.

I appreciate the fear factor at that time. Now this is like an UFO for me … I want this to happen to me…. Just like I would like to be picked up by an Alien spacecraft. Or a nymphomaniac Redhead.

Actually my creeping floormat is a constant problem, often affecting my clutch action. My wife's PT Cruiser has a nifty little hook on the floor that keeps the mat from creeping forward. Wish the SSR had a similar device. Any suggestions out there?
