Cam and lifter failure under 90,000miles on it had for about a year bought from dodge dealership they said there was no warranty or extended warranty coverage on it this is prime example of a lemon for the lemon law this is apparently a common issue on these engines with a repair cost of 4400 dollars or more this is unacceptable also the dealership has had my truck more than 3 months because they can't get the camshaft or lifters because of issues with them and are on backorder which means they have been putting in faulty parts into the engines
2012 Dodge RAM 1500 engine complaints
Page 4 of 7: complaints 71 to 100 of 170, newest first, as owners wrote them.
2012 ram 1500 - cranked my ram truck one morning and the engine had a knock with a tapping sound, turn off check the oil level which was ok! Started the engine and only heard like a mainifold leak. After driving a few miles , I notice that the truck was shaky during take-off or climbing a hill. Drop truck off at my mechanic for a tune-up and later that day my mechanic notified me the tune-up wasn't the problem. He remove the cams/lifters to #5 lifter and that lifter wasn't moving like 1,3 & 7. "is was like the lug on the cam were wore out."
Exhaust studs broke took to shop for repair got back still exhaust leak took back had to replace driver side maniford was told by dodge dealer shop that new design studs was available cause of the problem dodge had with studs breaking paid over $1200 for this work
Truck shuts down on occasions when you step on the brakes?
2012 dodge ram sport loses power and has an annoying ticking sound with it.. Ticking is constant and so is power loss. This happened two days ago.. Truck has 155,620 miles on it. Happened as I was getting on the the interstate..
Serious exhaust leak. Also, exhaust is leaking into the cabin. My 2012 dodge ram 1500 truck has 77,000 miles. I noticed a ticking noise coming from under the hood and a terrible smell inside the truck. I realized the vehicle has an exhaust leak. The leak is coming from the exhaust manifold on the passenger side. A mechanic friend of mine who works at a shop in gainesville fl told me his shop has repaired 125 of the same trucks in 2.5 yrs who have the same problem. The problem is the manifold bolts are failing/breaking which causes an exhaust leak which in turn causes the manifold to warp. My truck has now had the same failure and is currently at my local dealership. My truck was in motion on a city street. In my opinion this exhaust leak is a serious problem just like ford recently had with their police vehicles.
Vehicle makes a loud ticking noice at startup on the passenger side of the engine. Vehicle is stationary. Ticking noise stops around five minutes after the vehicle warms up.
The exhaust manifold leaks due to broken bolts adhering manifold to engine. The problem is wide spread and a known problem with this vehicle, it is possibly allowing exhaust gas into passenger compartment due to leak from poor design, costing consumer more than 1000$ to fix both sides of manifold.
My check engine light came on while driving apprx 65 on the free way. I checked the code p0305. Slight sputter at first. Now low power below 30mph and major jump into gear higher than 30mph. Almost as if skipping a gear. Mechanic diagnosed it as a cam failure causing a misfire, possibly from evidence of spring seizure.
My ram 1500 had valve springs break. It has a tick in the engine and the mechanic said it was a lifter. He said 2012 rams always get bad lifters, also the front seats the way they are shaped, when getting in or out the edges are rubbed and my leather is torn. The lifter is a major issue. I'll never by another ram again because of it. My truck sounds awful. I have 97000 mile it's 2012, looks beautiful, and sounds like a beater. It ticks when I start it and sounds worse when I drive. When my springs broke I was driving 70 on the intetstate.. The lifter issue came first, not sure if it caused the springs to break.
The lifters have failed and there is only around 80,000 miles on vehicle. After doing research I have found that this is a very common problem for the hemi engines that have the mds system. I should not have to pay thousands of dollars to have it fixed when this is a very well known problem and design flaw
Exhaust manifold bolts are broke off in the block!!!!!
While operating my truck in normal usage, the truck began to loss power, shake violently, and emit a knocking/clacking sound. The truck displayed a mil code p0304 for a misfire, one that was caused by defective, negligently engineered powertrain components. Camshaft and valve lifter failures are known issues on this vehicle across multiple model years. The moment when they manifest can cause driver distraction at the least, loss of vehicle control at worst. Fca should be compelled to issue a recall to cover repairs/reimburse those who have suffered vehicle failure. The parts alone will cost nearly $1800, with labor costs expected to at least double that.
Tl* the contact owns a 2012 ram 1500. While driving 55 MPH, the vehicle stalled and the check engine warning indicator illuminated. The contact coasted the vehicle to the side of the road and powered off the engine. The vehicle was restarted and was able to drive normally. In addition, when making turns, the vehicle stalled without warning. The vehicle was taken to autonation chrysler dodge jeep ram of katy (located at 21777 katy fwy, katy, tx 77450, (281) 715-6920) where it was diagnosed that cylinder number three was misfiring from the engine. The vehicle was not repaired. The contact later took the vehicle to an independent mechanic where it was diagnosed that the lifter in the engine and camshaft failed and needed to be replaced. The vehicle was in the process of being repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 94,000. The VIN was not available.
Tl* the contact owns a 2012 ram 1500. While making a right turn, the vehicle stalled without warning. The contact powered off the engine while in traffic. The vehicle was restarted and was able to drive normally. On another occasion, the vehicle failed to start and a clicking noise was heard. Also, the message "no fuse" appeared. The vehicle was not diagnosed or repaired. The dealer and manufacturer were contacted, could not duplicate problem. They said it is the tipm computer. Second incident occurred exactly the same as 1st incident (took to mechanic) told him truck stalled again making right turn at light, almost hit another car. The approximate failure mileage was 76,000. *dt*jb *tt consumer stated codes indicate major computer issues. Replaced battery, alternator maintenance to fuel tank, etc. Vehicle dies while driving. Dealer wants to replace fuel pump and computer tipm.
Vehicle fails to start in the morning. Once it is started, it runs fine. It will restart if not left more that 4 hours. It is parked in a garage at night and the temprature never gets below freezing.
There are thousands of ram 1500 owners having this problem. The lifters in the motor have a defect in the needle bearings, because of the demand for these lifters I will be without a vehicle for 2 months. I find this unacceptable and I guarantee you all the other owners do also.
Tl* the contact owns a 2012 ram 1500. While driving various speeds, the vehicle lost power and the check engine indicator illuminated. The vehicle was taken to an independent mechanic and was informed that the engine needed to be repaired. The contact called bob richards chrysler dodge jeep ram (1666 jefferson davis hwy, graniteville, sc 29829, (855) 984-5458) and was informed to schedule a service appointment.

I had taken my vehicle to lodi cdjr to have recall work performed. They then inspected my vehicle and found both exhaust manifolds warped and studs holding them to the block broken. They recommended replacement of manifolds. I had the work performed at my private mechanic who stated that they see this repair frequently. I looked at dodgeramforum online and saw this damage talked about a lot. It is my understanding that the 5.7l hemi block is aluminum and the exhaust manifold steel, 2 dissimilar metals. In the engine compartment where temperatures can exceed 400 degrees f and then cool back down, dissimilar metals expand and contract at different rates, putting sheering force on the connecting bolts, causing them to break. Which mine did. This repair cost me $890 and could easily happen again because the dissimilar metal situation is by design and really cannot be cured. I called a lemon lawyer who directed me to dodge's own customer service. I explained my complaint to the dodge customer assistance center representative (1‑800‑423‑6343) who said he was familiar with this complaint and recommended that I contact you. He gave me a reference number for my case: 57938794, to give to you. I feel cdjr is well aware of the flaw here and should be held responsible for it by recall.
Started hearing a loud ticking sound coming from engine on passenger side when engine is cold. Once engine warms up sound goes away.
Should. The leak and problem gets worse over time. 12/26/18-76,xxx miles.
Occasionally when decelerating engine shuts off causing loss of power steering. Has happened multiple times (3) over past year when on board cpu started causing single headlight to stop functioning. There are no traditional fuses for lights.
My 2012 ram 4x4 with the 5.7 hemi had 102k miles on it when I purchased it, at 105k miles the check engine light came on the code was po302 #2 cylinder misfire. I didn't make it to my 1st oil change b4 it went out. I have made 3 payments on it, now its a money pit and I can not afford to repair it, and if I let it go back to bank it screws my credit up lol how's that for you all lol I have 5 ppl in my family I traded my last truck in on this 1 for piece of mind for the family , now it is a yard ornament and soon ill be walking to and from work if I don't lose my job due to being late from having to walk to work lol if it wasn't for bad luck......
My 2012 ram 1500 has a knocking sound coming from the engine compartment and it usually fades out after running the engine a little while. Also the the power door locks will not lock or unlock using the switch and the front passenger side window will not roll down. The air conditioner seems to run warm from time to time and has been filled a few times but no leaks were detected. These issues happened over a couple of years owning this truck. I purchased this truck with around 30,000 miles in 2013/2014 it now has 50,000 miles.
Known major issue with with ram hemi 5.7l lifters going bad and eating into camshaft. My truck has started this problem and will only get worse without major repairs, causing decrease of acceleration and eventually motor lock up. Dodge/chrysler knows this problem and, as yet, has done nothing about it.
