4WD won’t engage, 2019 ram 1500

[Ajwood405]

Hello all, I have a 2019 ram 1500 I just bought. Has 40k miles. We got ice today and so I throw it in 4wd auto and it won’t engage, says to retry. I’ve tried cycling it like other threads have said. It won’t engage 4low 4high or 4auto. Please help! Going to see the dealer tomorrow but I’d really like to fix this

I had something similar happen around 35k miles. Not sure if this is the same issue you are having without pics of the error but when I put it in 4H or 4L the shifter would act up and the transfer case would go back to 2H along with getting an error on the display.

I took it to the dealer and turns out there were some outdated codes that needed to be updated. 20k miles later I have not seen that issue again.

Yeah it’s about 23 degrees. I’ve seen quite a few threads as well, just haven’t gotten any of the tricks to work

4 Wheel Drive (4WD) Not Working

Anyone have issues switching into 4wd? Today is the first day since buying the truck the opportunity presented itself with snow coming down here in the northeast. However, 4wd would not engage for me. While driving I tried switching into Auto 4WD. After blinking for a few seconds it would fail...

ill tell ya what, coming out of a 2015 1500 crew cab, its like dodge took everything they ever knew about building a truck and threw it in the trash.

exposed wires in the wheelwells. connectors full of water. ramboxes popping open. 4wd not engaging because its too cold. water leaks at the shark anteanna. water leaks at the brake light. cruddy sound systems. boomy echo-ey air chamber holes behind the seats.

chirpy brakes. uncut zip ties in the frame squeaking.

the list can go on...

How do you cycle? Cause i start at 4low and it just blinks for the longest. I’ve tried it in neutral, park drive everything

i think you got to get it to somewhere warmer.

i asked the dude in canada to get it into a barn or somewhere and he never came back.

but he said he was REAL far out. like would have to light a fire to make heat.

but if you have the means - see if you can get the truck warm. then see if it magically works.

i want to see if im on to somethin.

don't forget the rear doors that won't latch when it's cold out....grrrrr...this list is exactly why I leased my first Ram instead of buying

Saw a lot of tiny exposed wires under the car/next to the wheel base. Really need to put some electric tape on it.

im just blown away by it. and theres a post from just the other day where dudes park sensor got took out by a ice clump.

i go off roading. i run over small trees and crap. i should be able to in a 4x4.

these new gen trucks aint gonna make it between all the electronics and the way its wired.

 

[Ajwood405]

So took the truck to the dealership and waiting on answers. As soon as I get it I will post an update.

 

[Ajwood405]

Alright fellas, it was a simple fix. They said the actuator needed to be replaced. Going to pick it up today.

 

[rhinozeroone]

I just had this problem. They had to update the software and replace the actuator. It works like a champ now.

 

[Scram1500]

A manual override would be nice. This is the kind of thing you find out isn't working when you need it the most

 

[HemiDude]

I am imprerssed you could get it right into the dealer, have them diagnosis it, repair it correctly, and get back to you in a couple of days!

 

[Ajwood405]

Here is a copy of the report. I bought the truck Friday and I believe that’s why they got me in so quickly. Seems ECU and Actuator is the culprit most of the time

What did it cost you altogether?

Im having the same problem and from what i read, im hoping its the same thing and not something worse?
Ive heard about a recall on some 2019 transfer case so im not sure what it is. Unfortunately the dealer will not have an appointment till feb 21. A month from now
