Service Suspension Soon Warning

[bmelt]

Received a "Service Suspension Soon" warning message. Was not able to move out of All Purpose drive mode. But, I could change the suspension height without issue. Compressor kicked in, saw front and rear raise or fall depending on what I chose, etc. Called service and made an appointment to get it checked.

Service then had me do an infotainment reset, deep sleep for 2 hours, then a full reset. Let it sit for a few hours afterwards, and all warnings were gone.

That lasted for three days. Now, this morning, got the same ":Service Suspension Soon" warning once again with the same symptoms.

I can go over 51mph, I can change ride height via the screen, but cannot change out of the All Purpose drive mode while the warning is active.

I did the same sequence as before with resets and sleep, but no joy.

The R1T was at the Chicago service center for a week and a multitude of issues prior to this happening. Wondering if something didn't get plugged back in fully, etc.

Anything that I can check to somehow avoid the 4 hour round trip to the Chicago service center? Since I can change ride height, I could get under the truck to check related harnesses, sensor plugs, etc.

Thanks for any assistance!

Had the same issue. After 5 resets which each lasted for a different length of time, I took my vehicle to the Cincinnati SC. Determined to be low hydraulic fluid for the suspension. Inspected to ensure no metal shrapnel in the fluid to indicate part failure or corruption of the system. Has been fine since. Fingers crossed.

Only replying to say please DO not adjust height and then get under truck. If there is an issue or it fails while your under there, it could be fatal.
