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.

When does it fail?
Of the 31 electrical complaints filed for the 2016 RAM 2500, here's the actual mileage breakdown — failures cluster heaviest at 0-25,000 mi.
Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
Owners have filed 31 electrical complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
Owners of 2016 RAM 2500 trucks describe harrowing electrical failures: complete power loss while driving at highway speed, with no lights, brakes, steering, or engine function—power returns after seconds to minutes but leaves drivers stranded with dead batteries and inoperable vehicles. One owner with only 10 engine failures in the first month points to an overtorqued TIPM (Totally Integrated Power Module, part #68243265AD) that snaps its main terminal, causing intermittent power and shutdowns. Vehicle stalling at low speed with no warning lights and multiple failed restart attempts has been diagnosed as TIPM relay issues but remains unrepaired in multiple cases.
Backup cameras fail intermittently with scrambled displays; nav and radio screens black out on startup. Cruise control either won't engage or revs the engine uncontrollably; one replacement speed control switch failed again. Low-beam headlights burn out repeatedly; dealers acknowledge this as a known issue.
The ABS/traction control system is a widespread problem: the HCU module fails, disabling cruise, 4WD, and normal braking; owners note this system is under recall for 2017–2018 models using identical parts, but the 2016 lacks that recall status. Alternators fail early and recur after replacement. One diesel owner reports grid heater bolts corroding and dropping into the engine, causing catastrophic damage costing tens of thousands to rebuild. Battery corrosion with cracking and acid leakage occurs on OEM batteries within three years. Steering wheel controls and horns go dead. Transmission shifts itself without driver input.

What owners are reporting 4 most recent
When pulling a camper the truck shut off (there was no function of the gas or brake pedal) causing the camper to jack knife and hit the rear tail light. When the camera caught up to the truck wet spun 180 degrees at 65 MPH then flipped. No airbag went off and the seatbelt did not stay locked. My son who was sitting in the back climbed out of the backseat without unlatching his seatbelt.
Drivers window falls down when 'rolling' the window down.
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.
Common questions
How serious is the electrical problem on the 2016 RAM 2500?
It's a meaningful issue. 31 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $850.
At what mileage does the electrical typically fail?
Across the 15 complaints that reported odometer mileage, most electrical failures cluster between 18,000 and 34,000 miles, with the median around 24,000. A quarter of owners report trouble before 18,000; a quarter make it past 34,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $850 for electrical repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to electrical?
No active recalls currently cover electrical issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
