2022 RAM PROMASTER Complaints

Absolutely ZERO service parts availability for over a year now for the REAR BRAKE SYSTEM. no Rotors, brake pads, caliper assemblies from any RAM dealer in the US. This is a relatively new vehicle, however we cannot service our brake system because RAM will not supply the market with service parts!

The contact owns a 2022 Ram Promaster 2500 equipped with a Mobility Network I-Class Model, S/N: 75864-2020. The contact stated while lowering the wheelchair lifter with 600 pounds on the lift, the lift rubbed against the rear tires. The contact lifted the wheelchair lifter and noticed that the lift also rubbed against the rear tires. The contact checked the manual of the wheelchair lift and noticed that the lift was installed incorrectly, and that it was missing the filler plates, causing the floor of the vehicle to deform and causing the lifter to rub against the rear tires of the vehicle. The installation company was contacted but the installation company provided no assistance. The wheelchair lift was not repaired. The manufacturer was not contacted. The failure mileage was 9,239.

When using Adaptive Cruise Control (ACC) with Traffic Sigh Assist (TSA) engaged (the default) on an interstate or other high speed road - for example the current highway speed limit is 65 and the ACC maximum speed is also set at 65 MPH, the TSA (wrongly) detects a much lower speed limit, say 25 MPH, the system flashes a warning AND AUTOMATICALLY APPLIES THE BRAKES without allowing the driver to respond to the warning message. According to the user manual, what is supposed to happen, is that the TSA warning message displayed on the dash says "new speed limit detected" and SUGGESTS that the driver can accept the detected speed limit as the new ACC maximum speed by pressing the RES resume button on the the steering wheel. If the driver does not respond, the ACC max speed stays as set. This is seriously dangerous! imagine going 65 MPH in heavy traffic and suddenly, unexpectedly the brakes are applied so violently that the vehicle skids and swerves out of its lane. This has happened multiple times to me. I believe this is caused by 2 problems: 1 The TSA wrongly detects a significantly lower speed limit sign. I don't know for sure but I guess it might "see" a sign on an exit ramp or parallel service road. 2 The vehicle automatically sets the new TSA speed as the ACC top speed and automatically applies the bakes instead of allowing the driver the option of setting the new speed limit by pressing the RES button. I have spent the last week trying to report this to the RAM dealer and Customer Care but they don't seem to be very responsive. They say I should schedule and pay for a diagnostic session but they have no openings until mid-January. Even if I took it in, I doubt the diagnostics would show anything because this is most likely a software issue. It would also be difficult to duplicate on local roads. I do know another person who has reported this same problem on YouTube and is able to recreate it as detecting a speed limit sign on a parallel service road.

1. Service Airbag Warning Light - illuminates on the dash every 15-20 minutes while driving 2. Forward Collision Warning icon illuminates on the dash every time the vehicle is driven, regardless of the number of times it is turned off via the settings feature on the UConnect display. SOS Call Unavailable/Please visit an authorized dealer - this message pops up on the UConnect display every 15-20 minutes while vehicle is driven. I have taken the vehicle to a Ram/Chrysler dealership in Tucson, AZ. and the dealer has stated that they found nothing wrong with the vehicle and if the issue persists, there is nothing they can do and that I should just wait for a "bug" fix to be provided by Chrysler Corporation to address any potential software issues. I feel unsafe driving the vehicle, as I do not know if the airbag will deploy if i'm ever involved in a collision.

While using adaptive cruise control and traffic sign assist, the vehicle has a feature called intelligent speed assist. It is supposed to detect new speed limits signs and ask the user if they want to adjust their set speed. Instead, the feature automatically changes the set speed without user input. For example, you are going down the highway with adaptive cruise control set to 75 mph. The vehicle erroneously picks up a lower speed limit of 45 mph (could be for feeder road, highway exit speed, or old construction sign, etc...). Within a few seconds the vehicle begins to aggressively brake on the highway in order to reach the lower speed limit. This is very dangerous as it is a surprise to the driver and could result in a collision.

The text coincides with this video I made. Here is its URL. https://youtu.be/hpA-Dw_-ihY This is my second time reporting this issue. My first report was comprised of just text. I was told that a video would be more helpful. The issue follows: Periodically when I have been using Adaptive Cruise Control the van will automatically, harshly apply the brakes in the middle of the highway. It took me a while to figure out what was happening. It has to do with Traffic Sign Assist which is enabled by default. When the van detects a speed limit sign that is at a speed limit slower than what I am traveling, a message appears on the dash that says "New Speed Limit Detected. Press "Res" to Reject" This is the opposite of the way the owners manual says Traffic Sign Assist should work. The owner's manual says when a new speed limit is detect the user will be given the OPTION to accept the new speed. The manual says, if the user does not accept the new speed the vehicle will continue as it was. It will not apply the brakes. The consequence of the way it is implemented in my van is that if you do not see the message (because your eyes on the road) the van will AUTOMATICALLY apply the brakes. I have had it happen when traveling 65 mph and encountered a 25 mph speed limit sign at an exit. It only occurs with white speed limit signs. A 45 MPH speed limit sign appears on a service road at time :16. Just as the speed limit passes out of my FOV the message appears on the dash and the brakes are applied when I do not press "Res" to reject the new speed limit sign. Each of the times it happened in this video, first when it encountered a 45 mph sign and later when it detected a 55 mph, I was not expecting it. If you zoom into the video, or the attached picture, you can see the message.

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.

Speedometer units and units used to set cruise control randomly change from MPH to km/h occasionally when the vehicle is started. No safety risk. Problem has occurred multiple times but dealer was not able to reproduce. There are no warning lamp associated with this issue.
