Dodge RAM 2500 check engine light comes on

Filed May 27, 2026 · Engine · MT

We purchased our 2012 Dodge Ram heavy duty with tow package new. At just over 152000 miles, the engine started knocking while on vacation. We were not towing at the time. We put in injector cleaner to try and help the knocking. During our vacation, we were on the freeway when we suddenly lost power, the service engine light popped on, and the engine died. We were literally driving one minute and the next were trying to get out of the traffic lane with no control. We restarted the engine, the knocking had stopped and power was restored. Two days later, another episode of power decrease but with no engine service light. We used premium gas, injector cleaner and listened for the knocking that came and went, to drive home. We were told by our local dealership it is a lifter failure and the truck needs a replacement engine.

The TIPM module is bad. This part controls quite a bit of electrical current to various areas of the vehicle. It stalls when stopped at a traffic light, it is not sending the brake light information to an attached trailer (left side only), gauges inside the vehicle have stopped working (to name a few of the items being affected by this control). This part can be inspected as it is currently still on the vehicle. Safety is a concern due to either not being able to move out of the roadway, and also when pulling a trailer as no one will see turn signals or brake lights on the tow vehicle as the power isn't going to the trailer lights. I was informed of the malfunction at a trailer dealership. The problems have been getting worse over the last 4 years of ownership of this vehicle. The check engine light is currently on, even though what the computer read out gave has now been repaired. There has currently been no accident that this vehicle has been involved in.

I received a ve5 late life emission performance degradation recall in january 2021. I had the recall performed on 1.27/2021 at razzari dodge, merced. They installed a new cat converter and exhaust manifold. When I got my truck back, I had an cel error code p2271 o2 sensor. I had to pay $707.74 and $978.98 to get the truck running. I had no previous cel. I think they broke the wiring harness or o2 sensors when they performed the recall. . I think the ve5 recall repair, should make the entire emissions system function, including the control electronics.

The brake lights come on themselves when the truck is completely off. It's intermittent however it does it frequently enough to drain the battery. The engine light comes on as well however it does not provide a code to determine the cause of the issue.

Tl* the contact owns a 2008 dodge ram 2500. While driving 60 MPH, the vehicle hesitated, lost power, failed to accelerate, and stalled. Also, the check engine warning indicator illuminated. The vehicle was pulled over to the side of the road and failed to restart. The contact stated that code: p1451 appeared. The failure recurred five times and the vehicle was towed to smolich motors (1865 ne hwy 20, bend, or 97701, (541) 389-1177). The dealer diagnosed that the diesel particulate filter tracked soot from the exhaust and the lower particulate emission system failed. The vehicle was repaired. A month later, the turbo system failed and was repaired by a diesel independent mechanic. The manufacturer was made aware of the failures and did not assist. The approximate failure mileage was 151,000.

To whom it may concern, my wife and I own a 2011 ram 2500 6.7 turbo diesel. It was purchased new by her parents. I bought the truck from my in-laws a year ago and it's just over 80,000 miles. Unfortunately, over the last 6 months, we have run into a couple of major engine problems: -o2 sensor (includes overlay harness and module replacement), approx $1,500 -turbocharger - variable flaps not operating properly, approx $5,000 (according to rairdon of monroe, wa) everything I have read and every mechanic I have talked to (including the chrysler dealer) has said the only true fix is to delete the egr/emissions and run the truck without it. It is very strange that the most trusted fix is an illegal option and there is no assistance from chrysler for either of these known problems. Seeing as the delete is an illegal option, I attempted to go the legal route and get the o2 sensor fix at the dealer. Not minutes had I picked up my truck, driving out the of dealership, the check engine light came back on for the turbocharger. There is service bulletin for the o2 sensor issue, however it was never submitted as a recall. If it is a known issue (a manufacture error), why was there no recall issued by chrysler? It seems the overarching issue comes from the emissions equipment. Along with the o2 senor failing, the turbocharger is now spitting out an engine code (p2262). Due to the carbon/soot build up from the egr, the vanes of the turbocharger become clogged. This is also a known issue and not a recall. Please let me know what solutions are available. Thank you!

The emissions check engine light came on and was diagnosed as a overlay wiring harness that was faulty and needed to be upgraded. This vehicle only has 67000 miles on it and this item helps control the diesels emisiones. It should be covered by the factory for the 100,000 miles as stated. Upon contacting fca they refused to help in any way to cover cost of repairs. This repair is happening on multiple diesel rams . I only ask that fca be held responsibility for vehicles that produce and sell
