Accelerating under braking.

FlyingPhil · Feb 8, 2018

Two weeks ago, my wife was parking the Durango. She applied the brakes as she maneuvered into the parking spot. The vehicle immediately surged forward. She applied the brakes again, and the vehicle surged foreard again and climbed a snow bank before stopping. She thought that it must have been her, that she'd stepped on the wrong pedal. My wife has driven all sorts of vehicles and never had a problem like this. Then, two days ago, being particularly aware of her foot placement, again, parking, applying the brakes caused the SRT to surge. This time, she appied the brakes the second time with much greater force, and the vehicle stopped.
My wife is a small lady, with small feet, wearing her running shoes. Even when I try to depress both pedals at once, with my size 12's, I struggle. Anyone else seen anything like this?

can you repro it when you are driving?

Chase300 · Feb 8, 2018

Agree, I'd try to replicate with and without her driving.
She's not a two feet driver is she?

I'm wondering if the active parking sensors are malfunctioning. Instead of triggering a braking response its triggering an accelerator response. I have heard about it happening in some other vehicles. Try pulling into a close quarters parking situation to simulate. Saw horses with blankets would be great for this. The blankets are so you dont damage your paint if you hit one.

or empty cardboard packing boxes you can pick up at home depot or lowes. in case you are like me and dont have sawhorses laying around.

do you have adaptive cruise control? i dont, so not sure if it adjust speed up in addition to down.... if it does work like than and if you do have it, was acc engaged when this occurred (on, but not set)?

FlyingPhil · Feb 8, 2018

She's not a two foot driver. I do have adaptive cruise control, but it was not on at the time. This issue has so far happened only when parking face in to a snow bank or wall. I tried to simulate it this morning...and came up with ANOTHER issue!! Lots of snow here, with snow falling. Started the Durango, checked the mirrors, selected reverse, and immediately started to back up. After travelling about 5', the rear parking sensor sounded, the car stopped immediately, with the gear selector indicator flashing. There was nothing behind me. I cleaned off the parking sensors, and was allowed to continue. Not a big deal backing out of the garage, but what if I'd been backing onto a road? Having the vehicle suddenly stop in the middle of the road might not end well! Our new operating procedure will be to select reverse, count to three, then continue.

certainly sounds like a parking sensor issue. you can turn that off. see if the issue persists with it off.

I have had your second issue with it auto stopping in reverse. I live Michigan, and the sensors get dirty pretty quick right now here. Fortunately, at least for mine, it will give me a wipe sensor message along with sounding the close proximity sound, when they are dirty. I have had that happen with both the front and rear sensors. I don't have the tech package so it doesn't auto stop in forward, but it will in reverse. When it does this it will emergency brake, until you hit the brakes manually, and then start backing up again. When you start backing up again, it will still give the proximity alerts, but should allow you to move. This will work like that clean or dirty. So if you truely don't have anything behind you, then just apply the brake and go again. You can of course just hit the park button on the console to turn off the feature too. Using the button when the sensors are dirty, the alarm won't sound everytime you stop. Then when you get to where your are going you can clean them off.

I have my snowblower to the left of the rear of my DD in my garage. Depending on how close I park to it, that will engage the emergency stop backing out of the garage. Every time it does that it scares me into thinking I hit something.

Take that truck to the dealer and leave it there. That is a serious liability if the vehicle behaves the way you stated

CaptMoe · Feb 9, 2018

I would try and and get it to happen with you behind the wheel. If it only happens when she is driving, it might be something she is doing.
As for the stopping while backing out, the solution is simple, though maybe not easy to remember. After or during inclement weather, wipe down the sensors BEFORE you get in to back up. I have done this after experiencing the sudden stop two times and it hasn't happened any more.

Chase300 · Feb 9, 2018

We can thank a few Darwin winners for all this auto-brake, can't back up with door open nannies electrical sensor stuff.
But the brake pedal is pure mechanical...its not electrical. You press the brake pedal, the brakes are going to work. There is no connection to the accelerator pedal.
She might not know it but she has to be hitting the gas pedal slightly when applying the brakes.

FlyingPhil · Feb 9, 2018

I appreciate the input. My wife said the adaptive cruise control may have been armed while she was parking. I'm trying various configurations to get it to do this again...with me in the seat.

Or you can just hit the parking sensor button and turn the feature off. I have to do this while towing... Mopar isn’t smart enough to detect if their is a trailer hooked up then then obviously there will be something behind you when you try to back up [emoji57]. All my other cars have been smart enough to connect the dots.. with my WK2 SRT and DRST I have to hit the little button(and the. Remember to turn it back on when I’m finished towing.)

I don't know about Darwin winners but, the auto brake and backup cameras came about because of all of the kids that got killed when their parents accidentally ran them over while backing out of their driveways. I can't even imagine the nightmares those people had, and maybe are still having, after experiencing that.

I've had this happen twice. Getting gas in my wife's Durango Citadel and leaving the pump and turning, the car seemed to surge and the engine revs went up. I partially ran up onto a curb and got it stopped. I thought that maybe I had partially hit the gas while on the brake. I have a Durango SRT and I don,t believe it has happened in that car, but I'm more aware of my foot position since it has happened in her car. I'll just see if I can duplicate it again in a controlled way. Her car does not have the front parking sensors.

This has happened to me 3 times in the last few days. I thought I’d Google it to see if this has happened to anyone else. It seems so unlikely.

bbtkd · Nov 13, 2022

Every time this has happened to me, I've had my size 14's on the gas and brakes. You need to overcome the urge to press harder, lift your foot, slide left, and press. I've trained myself to constantly ensure that I slide my foot to the left half of the brake pedal every time I apply the brakes.

curthildebrand · Nov 13, 2022

I definitely did not have my foot on the gas pedal. This has never happened to me in my entire life except 3 times in the last few days. It was so weird that I thought I’d see if anyone else has experienced it. I see now I’m not the only one.

J'sR/T · Dec 9, 2022

This same thing also happened to my 21 Durango recently. I think around late Oct I was driving, came to a stop at a red light, foot on the brakes, engine rev'd up and it hit the auto collision brakes. I thought that was strange so I pumped the brake pedal a lil, and it did it again. The light turned green so I had to go, once I was stopped again I turned the auto collision/braking off. It hasn't done it again since. I haven't turned it back on to see if would do it again either.

It happened 3 times in 2 days then never did it again. It’s not as so strange.
