2012 Dodge RAM 1500: multiple warning lights

Filed Jun 25, 2024 · Brakes · NE

In approximately 2019 I received multiple warning lights including "Serv 4WD", TCS disabled, and ABS warning lights. Had it looked at by the dealer who replaced wheel sensors and performed diagnostics. All lights cleared exept TCS disabled warning which is indicationg that the TCS system is not functioning and has a collateral effect of the cruise control not being able to turn on. I have paid to have this remaining indication diagnosed on two different occasions, each leading to a dealership recommendation to replace the Hydraulic Control Unit / ABS Module at a cost of approximately $1500 and a wait for backordered parts exceeding one year - all with no guarantee of this fixing the problem. My truck has been in this condition for about 5 years now. A quick Google search will show that there have been multiple instances of faults of this type affecting the HCU/ABS modules with the problem becoming particularly prevalent in the 2017-2018 model years. Thousands of complaints have been submitted and Class Action Lawsuits started, but it appears FCA has yet to adequately address this potential safety issue caused by a defective part that is known to them.

Truck switched off, immediately switched back on, all dash lights flashed, transmission was in manual mode and showed in 6 gear. This happened four times within a 2 week period while turning slightly to the right and under light acceleration. My truck has been in a reputable repair shop for over a week and the technicians can't find out what's wrong. No computer codes were recorded.

Power windows worked wen they wanted to . While driving all warning lights would flash on in the cluster like I turned the key off then on . Truck kept running . Started getting hard to start . Once lost power while driving like it was running out of gas . Now it doesn't start at all . Had it towed to dealer they told me it was the tipm . I understand this is a common problem with the ram trucks .

For years now, while driving, some of my dashboard lights would be off, but not all of the time. Now all of the dashboard lights are off except for the speedometer. I can't see the gas gage or tachometer or temperature readings. This doesn't matter if I am stopped or moving.

When I turned on the hi beams (vehicle was stationary), the headlights flickered, all the dash light cut in and out, all the warning lights lit up, and the door ajar/lights on warning bells went off. I dimmed the headlights and it stopped. The dealer first said the alternator was bad, and it was only charging at 12 volts, so they replaced it, but that didn't solve the problem. Then they said it was the tipm. 17 days and $1351 later, I have my truck back.

Truck randomly shuts off while driving. All lights on the dash come on, once you get to the side of the road you turn truck off and restart it may run fine for days or a half mile. This can happen going 65mph down the turnpike or stopping at a traffic light in town. I bought the truck with 28k and this issue started around 32k. Had it to the dealership and was told "don't know what is causing the problem". My wife refuses to drive it because her and my son nearly got killed when it shut off going thru an intersection. I have read up on this on many forums and there are a lot of people having the same issue. You in fact had done a recall campaign # pe05027 back in 05. There are other models having the same problems. Is going to take someone loosing their life for this to get corrected. Make a payment of 400.00 dollars a month for a truck that I am afraid to drive. Someone please help!!!!!
