2018 Ram 1500 vehicle speed control problems

“XXX, [XXX] East Bound 9:30 PM, , pulling a tandem-axle boat and trailer 6000# GVW , the truck slowed suddenly, in traffic 62 MPH. I contacted CJDR dealers in [XXX], and [XXX], and both stated there was no recall, warranty, or goodwill repair, available for my truck. [XXX] told me the same, when I called. I took the truck to an independent diesel shop, in [XXX] to just go ahead and have a CPS (crankshaft position sensor, and tone wheel) put in. He said both the CJDR dealers and Stellantis told him the truck was “ineligible” for the repair parts kit – he was unable to obtain one. They claimed *my* truck did not have the faulty tone wheel assembly. In the mean time, the code he documented P0335, did not return, and I continued to drive the truck, until XXX, 11:00PM I-4 [XXX] about the 106MM, the truck did the same thing, same trailer, same danger. After restart, limping home, OBDii code P0335, was present. On XXX, I took the truck for diagnosis, to New Smyrna CJDR, and they completed replacement of the CPS and tone wheel, today, XXX. The repair cost me 3,470.98 on Invoice Number XXX. I purchased the truck from New Smyrna CJDR, three months after it was built,…”

“As we were driving along the freeway at highway speeds, the dash lights completely cut out on my ram 1500 2019. At first, this seemed to simply affect the visibility of the central console, speed controls, light indicators, etc. But then as we continued on and proceeded to exit the freeway, the entire vehicle shut down and lost total power steering speed control and power braking. I had to rapidly exit and take at safety on side of the road before completely losing control. Previously we had lost power to the video control display but it had never lost power before. We had also previously experienced where we were on the freeway at freeway speeds and the cruise control just rapidly shut down the same time as the video console shut down and the vehicle proceeded to slow rapidly and unexpectedly. After the incidence of losing cruise control and losing the central display, we took the vehicle multiple times to a ram authorized dealer service center in salt lake City as well as an independent shop. Neither could replicate and the issue as it is severely intermittent. We continued to use the vehicle given their clean bill of health. However, this incident showed a…”

“Prior to paying cash for this vehicle, I had the dealership connect it to an obd-11 scanner to ensure that there weren't any codes. (I wasn't aware at the time that if the codes were cleared prior to the test drive and before the vehicle was drove a certain amount of miles nothing would show up ) The truck seemed to be in ok condition. Before even making it 10 miles off the lot to my home the salesman who was to follow me in my new vehicle had issues and upon return to the dealership the truck had several "stored" and "active" codes which the salesman again cleared and told me to drive home and come back Monday with the truck the truck went into catastrophic failure and has been sitting since. The codes are P0365 indicating the entire PCM is failing or failed and P0606 an internal processor code which has to do with the computers not being able to calculate wheel speeds with the transmission and engine and how much gas to spray. And a P0616C EatC level 2 RPM performance code. There codes have to have been issues within the truck from my understanding to be both active and stored codes. I was sold a dangerous truck and they're not willing to give my money back…”

“I have a 2018 RAM 1500 Tradesman 2WD truck that the the ABS warning ligh as well as check engine, brakes warning light keeps staying on. I am very concerned about this as it may cause me to NOT be able to brake in time to. Also the cruise control does not work. I've taken it to several different mechanics as well as Autozone and I'm told the error code is C2200-49 which is the Anti-lock Brake Module Internal- Internal Electronic Failure. My mechanic has told me there is NO PART available and has been on back order for the past year. My only recourse is to locate one from a junk yard and hope that it will work. I've done an exhaustive on-line search and haven't been able to locate the module for my year and model truck through any RAM 'MOPAR' dealership. I've been on several different message boards and have been told there are thousands of trucks out there with this issues. Please, help us by making RAM do a recall on this vehicle. Sincerely, [XXX] ATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)”

“System involved: The vehicle experienced a sudden electronic/network failure consistent with loss of ECU/BCM/CAN bus communication. The instrument cluster, throttle control, and HVAC system became inoperative simultaneously. • Safety risk: While driving, the vehicle abruptly lost throttle response and critical driver information with no warning, followed by an uncommanded engine shutdown after coming to a stop. This created a serious risk of collision due to loss of propulsion, inability to react to traffic conditions, and lack of situational awareness. • Confirmation of issue: The vehicle was evaluated by an dodge service center, which identified an ECU software mismatch and performed a system update. The failure has not been intentionally reproduced due to safety concerns, but the incident is documented. • Inspections conducted: The vehicle has been inspected by an dodge service center. It has not yet been inspected by the manufacturer, police, or insurance representatives, as no accident occurred. • Warnings or prior symptoms: No warning lights, messages, or abnormal behavior were present prior to the failure. The malfunction occurred suddenly and without advance notice.”

“ABS light and traction control lights on, on dash. With these lights on, the cruise control and 4x4 do not work. One garage replaced front right axle, wheel bearing, brake rotor, brake pads, and ABS sensor. Lights were then out for a day but then came back. Took to a second garage and they replaced right rear ABS sensor. Lights went out for another day and then came back. They are still on. Because of Christmas it's been hard to get anyone to look at it. Also they say this is a known problem without any definite solution.”
