I have a 2020 RAM Bighorn, purchased in May. Now that the weather is turning cold, there are times where the remote start fails to operate properly if it sits for 24 + hours. Is this normal?

I have a 2021, no issue here like you describe.

I have a 2021, no issue here like you describe.

It could be a main battery issue. I may call AAA and get them to provide a free test. I do not have a tester, or I would do it myself. Is the battery covered under the 3-yr warranty that came with the truck?

I thought it was 12 months and under 12K miles

Maybe that is what it is for the battery. I will be calling tomorrow and asking, as I have a floor mat recall and will need an oil change.

 

[Neverstock21]

I have never had a battery issue like that if it is caused by an electrical component it should be under the 3 yr warranty.
Now having said that I just jinxed myself!

Are you over 1/4 in your gas tank? Remote won’t work if your not.

I usually never get it below 1/2.

REMOTE STARTING SYSTEM

The remote starting system will allow the vehicle to be started from distances of up to approximately 100 m (328 ft.) away from the vehicle. It operates using the remote keyless entry key fob which is part of your ignition key.

In order to remote start your vehicle, the hood and all the doors must be closed.

To remote start your vehicle, press the REMOTE START button on the key fob twice within three seconds. To indicate that the vehicle is about to start, the parking lights will flash and the horn will sound briefly.

Once the vehicle has started, the engine will run for 15 minutes. To cancel remote start, press the REMOTE START button once.

The parking lamps will remain illuminated to indicate that the vehicle has remote started and the engine is running. The lamps will turn off when the ignition is turned to RUN or the remote start is cancelled.

To enter the vehicle while the engine is running during a remote start, you must first unlock the vehicle using the UNLOCK button on the key fob. After the vehicle is unlocked, you have 60 seconds to enter the vehicle, insert the key in the Ignition and move it to the RUN position, otherwise the engine will cancel remote start and automatically turn off.

Remote start will cancel if any of the following occur:

• If the engine stalls or RPM exceeds 2500
• Any engine warning lamps come on
• The hood is opened
• The hazard switch is pressed
• The transmission is moved out of park
• Low fuel indicator is on. Low fuel levels
• The brake pedal is pressed before the vehicle door has been unlocked. If you remote start the vehicle while inside the vehicle and press the brake pedal, the vehicle remote start will cancel

The vehicle can be started remotely up to a maximum of two times. The vehicle is also allowed a maximum of one failed start. This is where the remote start sequence was initiated but the engine stopped cranking without starting. After either of these conditions, or if the Vehicle Theft Alarm is alarming, or if the PANIC button was pressed, the vehicle must be reset by inserting a valid key into the ignition and moving it to the RUN position, then back to LOCK.

If you have a push button start I believe you push the button and it moves to the run position.

Are you sure that there is not something inter-fearing with the signal from the key fob to the truck.

Yeah mine won't work once the low fuel warning comes on.

So it seems in the cold weather the battery does not have enough juice to do the remote start, after it has sit for a couple of days (36-48+ hours). I noticed that when I do start it has a hard, cold start, which did not occur during the summer. When I get my oil changed, I will have them check the battery along with doing the recall on my driver's side all weather floor mat.

Mine randomly wont start. Today I tried from Alexa and saw the lights flash but it did not start. I went to the door and pressed the fob twice and one flash...Just like what it does when the engine is remotely started and then I want to turn it off, so the computer thought the engine was running. Pressed the fob twice and got the the indications like it was going to start but it didn't, pressed twice again got the one flash like when turning it off.

Next time it doesn't start I'll turn on the ignition and look at the battery voltage.

This is what I did. The battery voltage rose to where I think it is supposed to be, right above the middle mark. It took 3-4 seconds to get to that spot on the meter (in-dash version). The dealership is now doing an overnight battery drain test. They wanted to say it was the dash camera, but it was installed in June, and never had any issues until it got cold out around Dec 1st.

UPDATE Dealership stated the radio was drawing down the battery. They conducted a warranty replacement on Saturday. I stopped driving the truck on Monday night, and went to crank it remotely on Wednesday evening. It did not have enough juice to do the remote start. When I started it, it was a cold, hard start. Back to the dealership, I guess.
