Vehicle wobbles immediately making the vehicel unsafe to drive. Several drivers have reported the issue to us. this is a fleet vehicle. Ram Promaster 3500 - 2021. We have documented invoices with this issues on 4 other Ram Promasters 3500. Please help as this is causing a serious problem with these vehicle going into the community.

Blind spot warning randomly disables itself and has to be enabled again through the control panel.

The Blind Spot Monitor turns itself off spontaneously. Complained to dealer for 18 months but they were unable to replicate. I finally realized I could lock in the "fault" if the headlights were left ON. Mechanic was able to determine the vehicle thought there was a trailer attached which disconnects the monitor intentionally. Cause could not be determined but a lighting module was replaced as it was their best guess. It has not reoccurred since and may have been resolved but I am reporting this as many owners of '21 Promasters have reported the same issue on a model specific forum.

Blind spot monitor system was disabled until recently since I purchased the 2022 Jayco Swift January 2022. Went to local Dodge dealer on July 11, 2022 to have them look at the Blind spot monitor and other items, see attached document item #3. I then learned from the Dodge Promaster Forum that many other owners had the same problem with the blind spot monitor would get disabled while driving with Promaster vans going back to 2016 at least. The Dodge technician could not diagnose the problem due to the original radio being replaced by the Jayco RV company, he could not see the signal from the computer to the blind spot sensors see note in item #3 from Rainier Dodge. I took the RV into the dealership that I purchased the RV from Valley RV Supercenter in Kent, WA on August 17, 2022. The technician there showed me how to activate the blind spot monitor system through the installed radio, but we were not able to verify it was working in the deal's lot. So it was agreed that I would verify that it was working on the drive home. Got on the road and it was working great, but while driving south on I-5 I hit some traffic and while driving in traffic I witnessed the system turning itself off in heavy traffic when it was most important to have it on. It made making lane changes in traffic more difficult and more dangerous. Could not turn on the system again while the vehicle was moving. I believe that repeated hitting the brakes turned the system off. I had to pull off the interstate and stop to turn on the blind spot monitor again. When I called the dealership and explained what had happened they told me I had to take it back to the Dodge dealership for them to look at it again.

Blind Spot Warning disables many times over an hour. Most obvious seemed to be related to braking.

We took the van on a trip out West in May 2022. During that time the Blind Spot Monitoring System would randomly shut off during our travels. It was random. Would happen a few time one day and none the next day. There were no warnings but the system alarm would ring when blind spot was disabled. I just had neck surgery and relied on the system during heavy traffic.

Most times when going down long grade over 6 + percent a dash warning comes on about service brake system. Once we get to flat area and turn ignition off the message goes away. We haven't had an issue braking. We are on Facebook group with other promaster 3500 and over 80 other similar vehicle owners stated this happens to them. Everyone says it's a "known problem" and not an issue and just ignore. We are worried what happens if it really is a problem. It happens every time we do mountain driving. I'd say over 10 times this year.

The blind spot detection system randomly turns itself off. The problem is the van is quite large with lots of blind spots, and you think the system is working because you have it turned on and it turns off by itself. Chrystler is not concerned with the problem, nor do they have a fix for it. This a safety concern that needs an immediate fix. The potential for loss of life is extremely high with this defect.
