Electronic parking brake engaging on its own

[hosseface]

Hello -

2018 Expedition Max Limited 4x4 - The electronic parking brake is engaging on its own.

Anyone else have this issue? It doesn't auto release when you hit the gas, you have to manually press it to turn it off.

Most every morning it is on when I go to the garage. Randomly in drive thrus or anythime it is running and sitting still the engages itself.

Any help?

Per usual, Ford service was clueless.

Thanks.

Makes me wonder if something with the automatic emergency braking is malfunctioning. The electronic parking brake engages when automatic emergency braking brings the vehicle to a complete stop.

From the manual; The electric parking brake may apply when
you shift to park (P) without the brake
pedal fully pressed. The electric parking
brake applies when you shift to park (P)
on large slopes.

It should release when you apply accelerator in gear. Also to release automatically, the door must be closed.

It also auto applies once the car senses its not on level ground, my mild (3 degree maybe?) driveway is enough to make the parking brake auto engage if the rear is loaded or I have a full quota of passengers but doesn't if I am in the car on my own.

Release doesn't seem to happen as soon as you touch the gas, it seems to me to be either a revs or pressure built type of deal. Bit like the hill start hold feature where you have to have given enough gas for the car to be sure you wont roll back

Hi, I have been researching about my 2018 Ford Expedition Max. I saw this thread and noticed that you are having the same issue as me. The electronic parking brake engaging. Mine engaging is very consistent, been to the Ford dealership in Tallahassee Fl five times already, still they are clueless. I cant get any help with this issue, I'm about to send out emails to Ford! Anyone else having this problem, please give some information. Thanks

only the Parking Brake kicks on automatically when on a incline and i would think also when on a decline.
If you are on a flat parking spot it wont go on. When we park on the inclined part of our driveway each day it goes on. Its not a problem is a safety feature.

Not necessarily...if you throw the vehicle into park or shut it off before it has come to an absolute and complete stop, or if your foot is not firmly on the brake pedal when you shift into park, the parking brake will also come on automatically.

It's not a bad thing. The parking brake will also disengage automatically when you put the vehicle in gear and begin to press the accelerator (gas pedal).

It also takes the stress off the transmission parking pawl as well.

I have had nothing but problems with my 2018 Expedition. I actually had to have it towed back to the dealership the day after I bought it and the main computer had to be replaced. All the other issues are very minor, but annoying. This auto brake issue is the only issue that myself or the dealership are unable to reproduce. I have kept a log where have I documented the time of day, weather and incline or decline if any. Sometimes it goes on automatically daily, sometimes just once a week or so. There has been months that went by with no issue at all. There is zero consistency to this issue.

I've noticed our 2018 Platinum parking brake seems to come on by itself as well but I never paid attention to exactly what the conditions were at the time. It always goes off as soon as I put the truck in gear and start applying throttle. It's never become an annoyance.

My parking brake just started engaging randomly, at about 15k miles. It has occurred 4 or 5 times now and always on flat ground. I've started to keep a log of when it engages by itself. Interestingly, the driveway on which I park is sloped significantly but the brake does not automatically engage. I engage it manually. However, after the vehicle has sat for 15 or 20 minutes, every time I open the drivers door the parking brake is heard tightening up. Anyone else hear this noise?

My parking brake has engaged twice in 2 weeks. Both times on level ground. Once in my garage and once in the level parking lot at my work. It does not disengage when put into gear and applying gas. I have to manually disengage it. This is in addition to drivers mirror thumping when resuming my memory setting. Rear taillight full of water. I think I bought a used lemon. But have always had almost no troubles with many Fords. Only 26,000 miles, one owner, special ordered Limited Max.

Any resolution to this issue? I have a 2019 Limited that has started applying the parking brake every time it’s parked and ignition is turned off.

Is there any way or setting that will allow the parking brake to be engaged once the transmission is placed in Park?

The newer RAMs have this option. Auto park brake. When set, the park brake will engage every time the gear selector is placed in Park. Not sure if the Expedition has the same.

I'm surprised at how many people (typical American) doesn't use their parking brakes and simply just leave the vehicle in park. I'd rather have the weight of the vehicle being held by the parking brake as primary and the parking pawl in the transmission as secondary.

I have a 2014 Impala 2LTZ with the electronic parking brake system.

The vehicle owner’s manual states that the car will apply the parking brake occasionally, if it is not set and used by the owner.

Have you read your vehicle owner’s manual to determine if your vehicle has the same type of feature?

My 2015 Expedition has a manually operated parking brake.

I recently had a rental Lexus SUV while my Expedition is parked at the dealer awaiting back-ordered steering gear assembly (53 days and counting today). The Lexus had an easy-to-use feature that would set the electronic parking brake when the gear selector was placed in park - and release the parking brake when the operator’s foot was on the brake pedal and the transmission shifted into gear. It was a VERY nice feature that I liked.

I have noticed that my 2018 XLT will put the parking brake on by itself occasionally - my impression was that it did it when parking on a hill, or maybe if it detects motion while going to park? No idea but it's not terribly consistent...
