I have a 2005 Dodge Ram 1500 HEMI.

What are the known problems that I might get?

Welcome to JustAnswer.

The Hemi has been pretty solid, but for a few areas I'll touch on:

  • Most every engine line has some problems, no matter how small. Its actual best virtue is that it's had so few. Considering its fly-by-wire and multiple cylinder displacement deployment happened at the same time, I consider it a major success. That said, some Hemi-specific problems have arisen.
  • Software. Probably the #1 issue with early 5.7s is with the software. If you live in a high-altitude area (such as myself), you would notice a number of malfunction indicator lamp (MIL) events connected to rapid altitude changes that the Factory hadn't counted on. Later software improvements appear to have taken care of all of these concerns. The engine controller (PCM) is flashable, meaning it does not have to be replaced to enjoy these benefits. Should you need them, they are available at your local Dodge dealer. Flash updates, should you request them, typically run at the one-hour labor rate of the dealership.
  • Broken valve springs. This isn't a terribly common occurrence, but does happen. No bent valves have been seen so far at my shop. A new valve spring gets you back into the game. Powertrain warranties apply (as far as I know) at this point with no transfer fee. It's a $100 deductible up to 80,000 miles.

That's about it. With two spark plugs per cylinder and two coils firing each cylinder, it's difficult to produce a misfire event that would turn on your CHECK ENGINE lamp. It's an engine that has such tremendous redundancies and great engineering that I'm proud to say that it's a Dodge. If only everything could be so well-built...

Last word (in my opinion), the Hemi checks OK. Change your seven quarts of oil at the recommended intervals, drive for years to come.

So there is 16 spark plugs? I ask this question becasue you say there wont be a missfire but I have a problem where I start my vehicle and go into reverse and then into drive and it stalls. Why? Even sometimes I go into reverse and it wants to stall but I give it some gas and it is ok until i go into Drive. I am 50000KM I can only get rid of this problem if I use 94 Octane gas.

I also hear that I will have a lot of transmission problems and rear differental problems. Mind you I have a 2005 the last model before the 2006/07 came out with a couple of callbacks.

Please if you can help me.

I stand by my mechanical view of the Hemi. Very good engine, few failures of any kind.

That said, and new information provided, I can provide you with a little more information, but positive answers require personal intervention.

Software was an early issue with the Hemi, being our first domestically-produced unit with drive-by-wire circuitry. Most issues were resolved by the 2005 year. You may want to check with your friendy local Dodge dealer for availablility of updates.

Lift throttle stalling could come from three sources.

  • First, software. I really know of no updates to the PCM software that affects lift-throttle stalling. Admittedly (from the gurus at Dodge themselves), updates sometimes encompass more than they are billed for. An unrelated update may do more good than advertised. Still, nothing known for this condition.
  • Crud buildup in the throttle body area. Original programming for airflow through the throttle body area does not provide for the inevitable buildup of crud as it accumulates in the blade/ bore area. This decreases airflow and might contribute to a lift-throttle shift-change event. Clean the crud off with a cloth (no solvent required), see what happens.
  • Transmission issues. If the stall event can be reproduced, try to relate it to a manual transmission when the clutch is left out. A manual transmission-equipped vehicle will have stall issues if you leave the trans in gear and fail to push the clutch in at stops. This problem may feel similar.
  • You may have to do several stops to reproduce this effect. When coming up to a stop, brake to around 5mph. Lift off the throttle and continue braking. Take it down to a single mph or so, feeling whether the engine is being dragged down by the vehicle speed. If the feeling is that the transmission is solid-locked to the wheels, the problem is with the trans. A trip to the Dodge Garage is then warranted.

There are too many variables for me to give you a definitive answer at this point. Use this guide for reference when talking to the repair facility so they may get to the root cause of your problem more quickly. At this point, I can't identify a reason why using higher octane fuel would be an issue, but include that in your complaint to the dealer.

I wish you luck. Barring that, a good driveability guy. Ed.

Thank you for your answer, just one thing, it is a automatic not manually transmission. any change in your answer?
Expert:  Dodgerench replied 10 years ago.

No, actually I assumed your transmission was an automatic.

Most of these issues with automatics stalling engines happen after driving a bit. Coasting up to a stop. Accelerate, then lift throttle, within 5-10 mph, then coasting to a stop. It may take several attempts, but might prove to be your problem. The key is whether it feels like the engine is locked to the wheels and drags the RPM down.

I have to admit to not being a transmission guy. My day job is driveability (fuel/ignition/emissions/etc). I've directed a few problems such as this to the transmission department, where they were resolved. Ed.
