Vehicle has problems accelerating. It will hesitate to accelerate when normally pressing the gas peddle. I have to floor it heading into freeway entrances, up hills or picking up speed over 40mph. Once it responds after a couple of seconds it over accelerates jerks and buckles then struggles to keeps a steady speed. It's a daily safety hazard merging into freeways cousing other drivers to suddenly slow down or have to change lanes because of this issue.

I just purchased a used dodge ram 1500 hemi, and dealer fixed 2 open recalls at the time. There was a slight noise under the hood at test drive and they took it onto their shop and said they replaced something, not sure what they said. But noise was reduced. I took car for a drive across country and when I got to my destination my check engine light came on. I got the computer reading to find out it was a cylinder 2 misfire. That shop said it could be from a number of things, but they were not a service shop to do a deeper analysis. I then took it to a shop that did a full diagnostic of the truck . Their findings were revealed that the computer was giving a cylinder 2 misfire reading but the problem was in the engine. They went on to tell me that they have been seeing the same problem in many of the dodge 1500. When they called to get prices on the used reconditioned engine, they were told that, there are is an huge back order for dodge 1500 hemi engine due to many people across the country having this same problem ( cylinder 2 or cylinder 8 misfire) this is definitely a trend going on with this make vehicle. With this problem , vehicle looses power and of coarse the slight hesitation in the engine. You can hear the misfiring and could feel it when I accelerate on the road and highway. When entering a highway , it is very dangerous due to not being able to accelerate enough to avoid oncoming vehicles

I bought 2012 ram 1500 in august 2018, I make payment. This past april vibration and hesitation got worse, I had plugs replaced , didn't help. Found out that lifters needed replaced and camshaft. I spent $217 on plug replacement and additional $4500 to replace lifters camshaft. Engine light comes on now it's saying vaporation leak. I have read that thousands and thousands of customers have had this problem and no recall from chrysler. This is my first dodge, this will be my last dodge unless I get compensation from chrysler. I know this truck is not under warranty, but chrysler has to know that this is a problem with the hemi , I was told at a dealer this was common in hemi , no one told me that when I brought I still owe on this truck , plus I'm out $4667 that I can't get back if I traded, only had 8 months when this happened. This doesn't include the the vap problem on the cost.

Engine ticks and lags/hesitate under throttle receive error code p0308, dealership recommended a tune up but did not resolve problem. Still hesitates under throttle. Did extensive research on-line and this is a common problem with the engine and costly to consumers and dangerous. In my case, I was entering a highway with my 2 kids. I was on the frontage road going about 40 MPH as I entered the on ramp of the freeway to get to the speed limit of 60 MPH. When I accelerated the engine started to hesitate and almost stalled causing the vehicles on the freeway to slam on his/her breaks and swerve to go around me. Fortunately, the cars behind me did not ran into me or anyone else causing a major accident as this occurred during rush hour on a major freeway.
