Dodge RAM 3500 check engine light comes on

Filed Apr 30, 2026 · Engine, Fuel system · AK

Driving my 2012 dodge ram 3500, just as I was crossing one of the busiest intersections in my town my truck lost all power and dropped from 35mph to 5 mph. Barley made it acrossed and pulled over. As soon as I pulled over the engine light comes on, checked code, and U010C lost coms with turbo actuator comes up. Turned truck off and rest code and everything back to normal. About a week later it happened again, luckily not as busy of a spot. Called dealer and soonest appointment was in April. Meanwhile I look up code and see hundreds of post for same issue, bad actuator replace. 28 years as a diesel mechanic for the military, so I found the part online and ordered. Replaced the actuator, drove about 50 miles, light comes back on. Finally get my appointment with dealer and they say my turbo is bad, they want $8k to fix. I ordered the turbo and replaced it myself along with another actuator, test drove. Light still comes on but have not lost power yet?? Dealer is not helping. This is a major issue that is all over the internet! The truck just goes to limp and your in the middle of traffic. If this has not caused an accident it’s only a matter of time before it does. The dealer ship just wants to replace big parts for lots of money. I’m already $2500 into this and still having an issue

A mechanic at professional auto shop diagnosed the failed TIPM. It caused the fuel sending pump in the fuel tank to stop pumping. The truck stalled while driving on the highway leaving me stranded in 2-degree weather. I read online that there was a lawsuit for this issue but don't know how to file to recoup the $1200+ repair bill on top of the $200 cost to tow it to the auto repair shop. There was an electrical draw and emergency flashers randomly turning on causing the batteries to die a month prior to the failure of the TIPM. I did have the check engine light come on when the fuel pump was cutting out and stalling. The truck is currently in the shop, and they ordered a new remanufactured TIPM.

While driving on a busy interstate highway recentally and pulling a car trailer, I was returning home from a vacation when the throttle position sensor (tps) failed. This results in a "dead pedal" situation, where the engine falls to idle, and there is no 'drive' to the wheels. This situation is very serious as sometimes there is no where to pull off the interstate, due to traffic lane narrowing. My personal situation was that I was able to coast to the side of the road. To re-set the tps, you must stop, put in park, turn the ignition off, wait approx. 10-15 seconds, and then re-start. It should re-set and you can drive away, although a 'check engine' light appears. In my case, the tps failed a second time, a short distance away, and I had to repeat the steps. The second time it "worked" and I was able to drive home. This failure of the tps had a profound effect on me personally. There is no warning that this is about to happen. When it does happen, you have no throttle input and you must get off the road. All I could think about during those moments of panic, was being smashed into from the rear! I am aware this is an issue with my type of vehicle as I have done some follow up research on the internet following my incident. I want to inform you, that I purchased the vehicle new in 2004. This vehicle is immaculate, and all maintenance is performed at the local dealer. In car guys terms, this vehicle would be considered a "garage queen" and there would be no contributing factors such as lack of maintaince, dirt, road grime, or abuse. I am convinced this situation will lead to a serious accident, if not to me, then to someone else, and I want to inform you of this potential serious issue. I have spoken to the dealer/mechanic and the solution is a tps replacement, but in my opinion, this should never happen in the first place.

My husband and I totaled our 2010 dodge ram 3500 less than 24 hrs after pick up the truck from the lythia dodge which they had for 5 days straight prior to the accident. For the steering, check engine light and the brakes. In 18mos my truck was in the shop 6 times, for repairs {unacceptable}. We were driving on a arterial st at about 35, when I heard a snap. We suddenly went into oncoming traffic where we sideswiped a sm SUV. Went thru two fences and crashed into a huge shop traveling about 210 yards. My husband was cited for neg 2. He stated he came to in the shop, the officer reported he feel asleep. My vehicle was a total loss. The auto source from the ins. For the payoff , had a list of recalls for my vehicle one of them was for the tie-rod. We recalled seeing the trucks tie-rod had been broken at the scene. So I tried to get my ins to investigate. They said his ticket was what they had to use for deciding fault .so I contacted chrysler they wouldn't talk to me they gave me a care no and said an investigator would come in 5 days, he came and got all the picts they wanted downloaded the brain history ,everything they could want. Then told me he could only give this info to chrysler, denying me any of it. Later chrysler informed me by letter that the tie-rod failure age was from the accident not the cause of it. I ask if the would consider the work orders that lythia had gave me {that clearly states they were beyond specification, never warning me of the dangers} and the picts. I took. I couldn't afford to fax them and they refused me an email address to send them. That evidence was not considered. They have not settled this with me only refused their liability. The airbags never deployed, and brakes were not applied. I got 3 notices for recall n49, 1 yr after the accident. Multiple recalls at that time, do a recall search by now VIN now and nothing comes up.

We bought the truck out of state from the chrysler dealership in bonham tx and they claimed it was a low mileage truck, with no issues. It had been purchased new from them, all services done and then traded-in for a new truck. We asked to have an outside inspector check it out but was unable to locate one from the small town area within the allotted time they wanted us to pick it up. When we went to get the truck, it went for a short text ride and then completed paperwork and rushed out the door. We had assumed that the dealer did a complete overall inspection and repair of any issues with the truck. On our way back to ca the truck water pump had broke causing the serpentine belt to fall off and loose steering almost causing the truck to wreck. We towed it to a repair facility where they fixed the pump and told us that there may also be a transmission issue. So the next day we went to the closest chrysler dealership to have it checked out. They ok'ed the trans and we purchased an chrysler warranty (because of the low miles & year) since we had bought it from a dealer (in tx) the truck was eligible for 48k/4 yrs coverage. A few days (2.4k miles later) the "check engine light" came on. We asked our local dealer to check the truck out to see what other issues it may have. The code was for the cam positioning sensor (covered by the warranty) and the dealer found other items including: needing new brakes all around, 4x drivetrain service, injector flush, air, fuel and oil filters that I have to pay for. The main issue: the front end with a bad steering box, tie rod ends and upper/lower ball joints need to be replaced. The chrysler rep said it is an pre-existing condition and won't cover the parts/labor. Both the warranty issuing dealership and my local dealership told me they would not have sold the truck in that condition. Are these covered under a recall?

While driving truck, throttle light starts flashing, engine light comes on and lightening bolt comes up. Car then loses all power and it dies. No notice. Very scary. Could cause serious or fatality accident since there is no notice and it just goes from 60 - 0. Dealer has had the truck in half a dozen times and still cannot fix the issue. Chrysler has given me case manager, but they cannot figure it out either. They have tried a few different things, but it is not fixing the issue. Now dealer says they dont know what it is and they do not know how to fix it.
