2016 Ram 1500: adaptive cruise control problems

Filed Nov 4, 2026 · Brakes, Electrical · FL

I am writing to file a formal safety complaint regarding a widespread defect in the Anti-Lock Brake System (ABS) Control Module and Hydraulic Control Unit (HCU) on my 2016 Ram 1500. The ABS system on my vehicle has suffered an internal failure, resulting in an active ABS dashboard warning light, total loss of traction control, and immediate electronic disabling of both the cruise control system and the four-wheel drive (4WD) system. Disabling ABS and the 4WD system leaves the vehicle unable to adapt to hazardous road or weather conditions, creating a significant safety risk. This exact failure pattern mimics identical ABS defects that parent company Stellantis/FCA has previously recalled on heavier-duty Ram platforms (such as the federal safety agency Recall 24V‑896), but the 2016 half-ton models have not yet been included in a mandatory remedy campaign. I request that this issue be documented and investigated as a potential safety defect requiring expanded remedy coverage.

Anti-Lock Brake Module Internal Failure - Code C2200-49 The truck ABS does not work, tractions control is disabled, and Cruise Control does not work. There were no lights or warning until the day I went to start the vehicle and then the abs, traction control, and brake light came on and stayed on once the truck was started. With researching this issue, it seems to be a widely known issue for several year trucks and parts to repair the ABS module are no made any longer. Calling the dealer the replacement part, which from what I read has been redesigned and is on an unknown backorder timeline. The cost for the part and labor is very high. From what I have read there was a TSB/Recall on some 2017 and newer ram trucks. I have not been able to determine if this is the same ABS module that is being used for the replacements in the older rams trucks. The truck without ABS and traction control is dangerous. I was on the highway and traffic came to an abrupt stop and when I applied the brakes my rear tires started to lock up. Luckily I am a defensive natured driver and was able to keep control of the vehicle and adjust my braking pressure and move towards the burm of the highway. In rainy conditions and others, it is going to be scary as well as trying to drive with wet/icy roads with no traction control it is not optimal.

ABS module failed causing ABS, traction control, and cruise control to stop functioning along with intermittent loss of power steering. Contacted multiple dealers which all stated the part is no longer available and no replacement part. This was a nuisance for two years until I towed a trailer and was merging onto an interstate when I lost traction due to wet roads and no traction control. Vehicle and trailer fishtailed and I was barely able to gain control without contacting any other vehicles on the very busy interstate. I was able to find a rebuilt abs module on eBay for $1100 that I installed and corrected the issue. This year model needs to be added to the existing recall that has been posted for many other years for this exact issue

The dealership said I need my ABS module replaced due to the lights on the dashboard and my ABS braking system and cruise control not working. I had them order the module and paid for it. I finally asked for a refund. where it has been on backorder for 18 months as of 8/13/2026, with no idea of when it will come in if it comes in at all. This is an extremely disturbing situation and safety issue of not having the anti-braking system in operative.

The ABS (Anti Lock Brake System) Module has failed. ABS, cruise control, and traction control are disabled. A faulty ABS can cause an inability to stop suddenly to avoid a collision. My specific issue has been confirmed by a Ram dealer. Chrysler engineering has confirmed this is a widespread problem with multiple vehicles using the same ABS Module. It is not possible to get a replacement ABS Module. Auto parts stores and dealers do not have replacement parts. There is a waiting list for a redesigned ABS Module at my local Ram dealership. The first person on the list has been on the list for 3 years. A new module, installed and programmed, will cost over $1200. A faulty ABS is a safety issue. I recommend Ram/Chrysler issue a recall when parts are available.

How was your safety or the safety of others put at risk? - Without a functioning ABS Module, the vehicle has no Anti-Lock brakes or Traction control...in addition to no functioning cruise control and some 4WD features. The main concern is obviously the absence of ABS and Traction Control, which can cause loss of vehicle control.

Failed abs module prevents use of abs braking system causing wheels to lock up under hard braking. Collision almost occurred as result of wheels locking due to failed abs module and Stellantid does not have a replacement part available. Also prevent proper use of cruise control, stability/traction control and braking. Have been advised by dealerships in DeLand fl and Daytona beach fl that the part is on indefinite back order.
