Dodge RAM 1500 misfire problems

Filed Apr 17, 2026 · Engine · MD

My 2012 Dodge developed an engine issue at 129,000 miles. The issue was rough idling and no acceleration. I took it to a Dodge dealer. They diagnosed it as a chronic cam issue with this generation Chrysler hemi engine. I had the cam and replaced at Waldorf Dodge. The cost was at $3400. I believe this is a known problem and Dodge is aware of exactly why it happens. Lack of oil pressure to two of the cylinders that are dropped while driving for fuel economy. This should be Dodge problem not the consumer. I take excellent care of my vehicles. I also have a 2004 Dodge truck but that’s over 450,000 miles on it same engine same transmission.

The contact owns a 2012 Dodge Ram 1500. The contact stated that while driving approximately 65 MPH, the check engine warning light was flashing, and the vehicle unexpectedly decelerated. While depressing the accelerator pedal, the vehicle was shaking and continued decelerating. The vehicle was pulled over to the side of the road. A certified mechanic was contacted and advised the contact to drive the vehicle approximately 45 MPH with the hazard lights flashing to the repair shop. The mechanic diagnosed a misfire in cylinder #2, lifters failure, causing the camshaft failure, which allowed metal debris to enter the engine.

The vehicle finally became inoperable at 119,000 miles due to lifter failure. Lifter issues started when the vehicle had about 106,000 miles on it. There were multiple misfire and gas mileage became worse. There was a loud ticking noise coming from the engine as well. Vehicle has been well maintained and only 1 owner, purchased new. With the lifter failure, this caused damage to the camshaft and which led to an excess amount of metal shavings to be spread throughout the engine. The vehicle ultimately had to get a engine replacement because of the excess metal shavings in the engine.

The engine has lifters ticking when cold and a loss of power during operation. The engine hesitates during driving at different times and runs rough. There is no warning before this happens and no warning lights/sensors activated. The truck only has 76k miles on it.

I was driving at highway speed. The vehicle suddenly lost power and began to shutter. It was difficult to control and the vehicle behind me had to swerve to the inside lane to avoid a rear end collision. Upon receipt and diagnosis from Olathe DCJ, they indicated there is a misfire in cylinder 5. Through a Google review, I discovered this is very common know issue. It costs anywhere from $3500-$15000 to resolve let alone the risk to life. In discussion with my service advisor (Mike), they perform this repair a couple of times a month. This is in one location in the Kansas City area. I can only imagine how widespread this issue is.

The camshaft is defective and prematurely wearing down due to the lifters. Causing a warning code to come on give a p0300 code and and check engine light to flash at a random mulitipule misfire to come up will cause the truck to die at times causing a crash. Luckily I was able to park it before that happened and now can't drive it because of the saftey Hazzard.

Camshaft lobe warn down from, from faulty rocker arm roller (needle bearing) (there is no to very little compression in cylinder 5), apparently engine is lubricated "by splash oil design" and people smarter then me have diagnosed that it is a design flaw.(having to do with the well and the height of the bores that accept the rocker arms) The engine only had 118,000 miles when the engine light came on, resulted in a severe knocking sound and misfiring. I expected a well taken care of motor with regular oil changes would last 200,000 miles. My choices are to rebuild the motor and or replace, both are costly. Thanks for taking the time to read my complaint. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Spark plugs and plug wires were replaced 3/21/21, driven again on 3/22/21, same issue, almost causing another crash due to loss of power on the interstate when merging, and then shaking almost sending the vehicle into bridge.

I was operating my vehicle when it presented a check engine light. I utilized a code reader to determine it was a cylinder 5 misfire code. The code disappeared after roughly 30 seconds. About an hour later, the check engine light came on and stayed on. The truck started violently shaking, causing me to almost lose control of the steering wheel. I had to quickly pull off to the side of the road from the middle lane, almost causing multiple accidents as my speed rapidly decreased. The shaking continued for another two minutes after which it stopped. I was able to get the vehicle home by traveling at a low rate of speed and keeping the engine speed under 3000 RPM. The issue was diagnosed as a failing camshaft and lifters causing a misfire and the loss of power. This is a serious safety issue, and I am not able to drive my vehicle for fear of the misfire occurring again and me losing control of the vehicle causing an accident.
