ABS FAILURE, WHICH TURNS OFF TRACTION CONTROL AND CRUISE CONTROL. This is a known issue for the HCU to fail. How is this not a recall on 2016 but it is on 17 and 18. Same parts.... have replace front hubs with new ABS sensors and rear ABS sensors, still on. It has to be the HCU or the module.
My ABS lights is on causing my cruise control to not be functioning. When I first start the vehicle, i get a message to "service electronic brake system." I have new brake pads with rotors and still have this message.
ABS system/ Traction control system/ 4wheel drive system/ cruise control. I had the ABS system repaired/replaced once this year already and now i need it done again. ABS failure makes the 4wheel drive system fail and it's winter time and i need 4 wheel drive for safety.

6.7L Cummins diesel Known Grid heater bolt broke and could leave people stranded as it causes catastrophic engine failure and or damage leading up to $20 to $30K in engine repairs. Ram knows about this issue and is doing nothing about it. Mine broke and I caught it just before it destroyed my engine. the fix was a $1k kit. This bolt corrodes and and drops down into the intake in which destroys the #6 cylinder, piston, wall and valves. Ram is doing nothing to fix the problem and leaving people stranded who haul trailers and with the big repair bills.
The grid heater bolt that is on the bottom side of the grid heater. It fails and the bolt falls off and get sucked into the engine destroying the piston and cylinder causing an over 10,000$ expense.
This message is in regards to Static NHTSA Bulletin 09-005-22 / D- 22- 06 Dated March 16, 2022. The above listed warranty extension extends Ram 2500 Cummins Turbo Diesel Model year 2015 to 150,000 miles or 15 years if code U010C is indicated on MIL. My truck meets all above criteria but is a model year 2016. However, there is no changes in mechanicals between the 2015 and 2016 model year. My truck, at 114,000 miles just indicated this issue and the estimated cost of repairs is over 2,000 dollars. Considering that this has already been a widespread notable issue with this truck and engine, my hopes is to include 2016 model years in this extension. Thank you.
When vehicles comes to a stop or a slow roll. It makes a loud humming sound and cuts off in drive. The lights starts flickering ans The check engine flashes on at that time. Received a ecm code.I have to place in park and restart. Happens 70% of the time in drive and other times in reverse or park. Cruise control would not turn on. If on will not turn off with buttons
It seems that this is a common problem on these trucks the HCU for the antilock braking system and the ABS module has to be replaced the traction control light comes on the ABS light comes on and the cruise control does not work.
The contact owns a 2016 Ram 2500. The contact stated that while slowing down for traffic or traffic signals at approximately 10 MPH, the vehicle would stall. The contact stated no warning light was illuminated. The contact stated that several attempts were needed to restart the vehicle. The failure became constant and the vehicle had to be towed to a dealer. The contact had taken the vehicle to the same local dealer several times for the same failure. The dealer had diagnosed the failure and determined that the vehicle needed to have the Totally Integrated Power Module (TIPM-7) bypassed to a new TIPM relay. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 14V530000 (Electrical System). The failure mileage was approximately 125,000.
For the longest (approximately two years now), my backup camera would "go out" sometimes when I engage reverse, or it would show squiggly lines to where I can't use it. This happens quite often - especially when I need it. The truck is available for inspection upon request and I also have videos of the issue. For a truck of the height, I'm not able to see objects, animals or people when backing up from a stop. I took it too a dealer near me and they inspected the system and found nothing wrong. But the same problem persist. There are no warning lamps or lights when this happens. Pictures are attached for reference.

T79/NHTSA 17-821 RECALL.. JUST WONDERING IF AND WHEN THE FIX MAY HAPPEN? IT HAS HAMPERED MY CHANCE OF SELLING IT DUE TO THE OPEN RECALL AND THE FACT OF NO GIVING DATE AS TO WHEN IT WOULD BE FIXED, DEALER WILL NOT BUY IT ( THE ONE WHO WOULD, WOULD ONLY GIVE A SMALL PERCENT OF IT VALUE) AND A BUYER BACKED OUT CAUSE OF THE TYPE OF SAFETY ISSUES IT IS. I SPOKE TO THE DEALER SHIP AND THEY HAVE SAID THAT THEY HAVE NOT BEEN GIVING ANY IDEAS OR A TIME FRAME WHEN FCA WOULD HAVE A FIX. JUST WONDERED WHAT IF ANY OPTIONS I MAY HAVE TO GET IT FIXED OR GET A SAFER VEHICLE. THANK YOU
