My 2016 2500 LML required the brake to be pressed to remove from park.  Owners manual indicates that’s the design. 

Interesting.

 

Because of this thread, I verified today that brake pedal is unnecessary on '18 L5P (even though I usually use it anyway). 

 

Had both a 15 and a 16 1500 around here.  They both required the pedal be pushed -- the shift lock did work on them. also works on GM car that is here.

 

The other difference is that this L5P can be started without putting foot on brake pedal --- again, a difference from the 1500's which wouldn't start without pedal pushed.

Could be it's in need of repair.

Just curious, why wouldn't you apply brake from park-reverse or park-drive? I don't see the need, so I'm curious.

 

my '19 1500 jumps quite a bit when put into drive, especially if it isn't warm and idled down yet. It's unsafe, not to employ the brake.

This is my brothers truck. It is the ten speed.  He just got it back. There was a wire in the harness of the steering wheel that was crimped at the connection. All good and working now. 

I found your post by googling the problem, Thanks Google. Also joined this forum. I just bought a 2020 2500HD High Country. Its having the same problem with shifting out of park. I wonder if its the same problem? I will take it to the dealer and let them know how yours was fixed and keep you posted.

My brand new 2020 2500 high country get stuck in park about 5-10% 0f the time. Dealership wants to try a new steering column. I thinks is has to do with the communication with the brake switch and a wire in the shifter. I can’t believe with so many of these trucks doing this that GM hasn’t come up with a resolution.

Mine did this for the third or fourth time last night, in a month of ownership. 
 

I tried turning the wheel, restarting several times, off and on the brakes; nothing. 
 

I finally just overpowered it and got it out of park. 
 

it seems to function as expected since - meaning you have to press the brake to both start it and get it out of park. 

 

Message on the DIC says “press brake to start” so I’m sure it’s designed that way. Message goes out when I hit the brake so I don’t think it’s the electrical switch.

My truck started doing this a week ago and happens every time I go to put it in gear.  Brought it in today and the dealer called back saying there is a bulletin on this and when it does this they need to replace the shifter and the bolts to the shifter.  Shifter is on order and will be in a day, however, the bolts are on backorder.

Well that’s good news. I have not returned to the dealer because I bought mine at one dealership and plan on having it serviced at  another.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.

      "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
