2013 F-150. Today i saw my truck roll backwards after i pulled out of the garage and put it in park. I am very positive it was in park. I pulled it out put it in park, got out and started to roll backwards. it rolled probably about 6-8 ft before i jumped in and pushed on the brake peddle. I looked at the gear sifter on the dash board and it was in "P". The other day my wife said she saw it roll back, but it stopped on it's own. i did not see it only the wife.


note: my drive way is 5%-4% grade. I have always parked it in the same location and never had this happen, so i am pretty sure it's not my parking drive way.

Is there a tsb on this? has anyone ever had this happen to them?

Shifter linkage under the steering column might be loose, not sure if it's the same with my 2000 but it was just a loose nut. Tightened it up and it's been fine ever since.

Anytime you park on a grade in any vehicle you should use the emergency brake instead of letting the vehicle rest on the parking pin. Stop in your driveway, hold the brake, depress the emergency brake with your other foot, and then place the vehicle in park. This is how all my vehicles sit parked in my driveway. I was told this along time ago by a transmission mechanic.

Interesting that i have never had this problem in the 2 years that i have had this truck. I park it in the same driveway but after this i will start doing that. hopefully i remember.

when in two wheel drive is the truck front or rear wheel drive?
I did see the front tiers moving but did not look at the back wheels.

Your truck is rear wheel drive unless you put it in 4 wheel drive.

First truck?

One bit of advice when doing this, is don't leave the vehicle parked for an extended period. My father warped the rotors in his 2001 F250 diesel two years back by parking it with the emergency brake and then leaving it to sit for 2-3 months. Now he uses wheel chocks when he knows it will not be used again for a long time.


Also I don't know if it is common any more, but do we still have to worry about our parking brake not disengaging if it has not been used in years. I know this was a fear with my first truck and other 80s and 90s cars and I avoided the parking brake simply because I didn't know if the last owner ever used it.

The parking/emergency brake is actually a small set of drum brakes built to fit inside the rear disk/drum rotor. That's why the rear disks are so big in the middle. Not sure how using that could warp the rotor. The outer disk pads Front and rear are not being depressed when you use the parking break, only those internal drum brakes are.

Well that is good to know!


Does that hold true for all emergency brakes, or only those on our F150s? It was a friend that works on cars that told him this and fixed his truck. It was not an F10 but an 01 F250 diesel with a manual trans.

The last 5 Fords I've owned were like that, but my wife's Mazda is not. Might be an American auto thing.
