Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Ram 3500 6-cyl

  • 135,000 miles


Seems to occur when it is damp or raining. Doesn't occur when it is dry. Revs up on its own, even in gear with foot on brake. It has done this at least once. When first cranked up it has revved up wide open. It has done this at least twice. Will accelerate on its own while driving down the road. Has done this several times. When accelerating and you let up on the accelerator a little it acts just like you have taken your foot completely off the accelerator. It has done this several times. After the weather dries up and you crank it a few times the check engine light will go off. The light will stay off until the next time it is damp and it decides to go crazy. Then the check engine light comes back on just as soon as the engine starts to accelerate on its own. I think this is extremely dangerous.

The lift/transfer pump of the fuel system failed while driving on the freeway. (separate from the main fuel pump ). after talking to my mechanic and researching online, I found that apparently the original system was such a terrible design, and the problem I had so common, that Dodge doesn't even make a replacement part for it anymore. Instead, they sell you a kit which requires about 5-6 hours of labor to totally re-do the system (plus $500 parts). Customer service" forget about it. If you finally get through to talking to your "case manager" all you'll hear is: "it's no longer covered by the warranty" the problem manifested itself by my truck stalling out in the fast lane on the freeway during rush hour- not a lot of fun trying to steer/brake a 6000+ pound truck with no power steering or brakes! how could this not be a safety recall issue"

Ram 3500 Diesel

  • Manual transmission
  • 119,000 miles
Failure of 2003 Dodge Ram 3500 with ho diesel engine and manual 6 speed transmission - engine turns over but fails to start. Been to crown in nitro and courts in hurricane a total of 7 times. Dealerships fail to fix. Have spent approx. $2500 and still not fixed. Can stall at intersection or railroad crossing causing grave injury or death; need help to get problem fixed by recall process. All Chrysler-Dodge says "I apologize". Chrysler-Dodge knows of problem B/C will fix on as need basis if under warranty; told by crown, nitro that we were lucky fuel pump lasted as long has it had when replaced (we had to pay) over a year ago. Has caused compounded problems with injectors. Mostly likely has caused high pressure pump then injectors to fail as these parts use the lubricating properties of diesel fuel as the lubricant for these parts.

Started noticing truck hard to start, then it dies at idle, in traffic etc, it happens about anywhere from 4 times a day to 4 times a week just depends, told that the truck transfer pump is a dealer item only at about $400 over the coast of internet pricing for the kit, wouldn't this be a recall? I have searched an found numerous other complains on this same problem, but since Dodge discontinued the exterior transfer pump then it was a design flaw and should be a recall I had my truck die on my 2 times today in traffic moving 70 miles an hour with kids in the back seat and an 18 wheeler behind me, the truck has no other problems but I don't think Dodge should be allowed to change the design with out having a recall.
