Is intelligent speed assist implemented backward in the new Ram Promaster 3500? I attached a screenshot of the owners manual page describing how it should be working. I have experience several instances of the van automatically slamming on the brakes when traveling down the highway when the van recognizes a 25 mph speed limit sign for an off ramp. I have not been the only one. There are other posts about similar situations on the Ram Promaster Facebook page. I have a 2023 Solis 59PX that is built on the (new) 2022 Ram 3500 chassis. My Promaster happened to come with adaptive cruise control. This post is regarding the implementation of the intelligent speed assist feature which can automatically adjust the max speed of the van based on traffic signs it recognizes. The manual says that "the message in the instrument cluster display will indicate the new detected speed limit by suggesting the driver to press "RES" to accept it." Where the manual says the instrument panel prompts the user to press a button to accept the suggested speed, I recall my instrument panel requiring me to press a button to dismiss the accepted speed. If I didn't see the prompt to dismiss the new speed, I recall the van automatically changing speeds. I recall mine switching speed on several occasions, automatically, without having to press anything, which resulted in some dangerous moments when traveling 65 MPH on the highway and the van detecting a 25 MPH sign for an off-ramp and slamming on the brakes. I am wondering if it is implemented backward in my van. I recall it saying "dismiss" where the manual says it should say "accept". The manual describes the system working in a way that makes more sense to me and is opposite of the way I recall mine working. In the manual it describes the system making a suggestion to change based on the sign but requires user input to actually accept it. There are several posts about the same thing on the RamPromaster Facebook page.

I'd like to report a safety issue with the RAM PROMASTER 3500 chassis. Ours is a Winnebago Solis PX Campervan. The sliding van side door is often impossible to open from the inside. There is a plastic lever that doesn't catch and is ineffective. I've been locked in many times after pulling and pulling on it and when the front seats are turned around for camping it's difficult to use the front doors to exit. Obviously, in case of an emergent need to get out of the van, this is dangerous. I've seen many other owners of this model complain of the same issue. I believe its serious enough to require a recall but in any event, it should be redesigned immediately. There has not to my knowledge by inspected by any of the entities you've listed though I don't know if others have complained to them. It is available for inspection. Thank you.

Electronic parking break automatically applies when the vehicle is in gear (drive/reverse) when beginning to drive up or down slopes. This limits drivers ability to control the vehicle when driving up or down hilly terrain. Problem has repeatedly occurred but dealer was not able to reproduce issue. There are no warning light or messages with this issue.

The contact owns a 2022 Ram Promaster 1500. The contact stated while driving 30 MPH, another vehicle overtook his vehicle and the vehicle experienced phantom braking. The Forward Collision Avoidance warning light was illuminated. Additionally, the contact stated that the odometer indicated that he was driving 15 MPH while he was driving 60 MPH. The vehicle was taken to an unknown dealer who could not duplicate the failure. The vehicle was then taken to a second dealer where it was diagnosed that the Forward Collision Avoidance camera needed to be recalibrated. The contact was informed that the cracked windshield needed to be replaced. The dealer was awaiting the part to replace the windshield. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 30,000.

A big chunk of tread separated from the tire while on a 3000 mile trip. We believe it occurred when we were nearly home and were lucky that there was no blowout. There was no damage to the tire that we are aware of but it could have been very dangerous situation.
