Owner reports

Selected complaints filed with NHTSA by 2012 Dodge Ram 2500 owners, lightly cleaned up (personal details are redacted by NHTSA).

Our 2012 RAM 2500 truck with 135k miles, had it's fuel tank fail. The dealership in Oak Ridge, TN tested the vehicle and found that the gas tank tubes were broken causing us to not be able to fill the tank. The dealership recommended "NEED TO REPLACE GAS TANK". Mopar aka Stellantis does not make the fuel tank anymore, the "replacement" fuel tank does not work (completely wrong configuration), there is not an aftermarket tank. We have a Million Mile bumper to bumper warranty with MOPAR. "Customer Care" does not care.

My passenger headlights keeps going in and out. The wiring harness has been replaced twice and it still does it. My check engine light keeps coming on for the evap system even though its been replaced.

Prior to epa emissions recall I would achieve diesel fuel efficiencies as high as 21 mpg highway, pulling a 18 foot trailer at a 1 hour duration. The city mpg averaged to 13-15 mpg, since the emissions recall update made on this vehicle, mpg has averaged between 10-13 mpg on highway with no load/no trailer and averages between 9-11 mpg in city. These benchmarks have been consistently compared and road conditions have been same. To add to this issue, there has been a loss of power that has caused unexpected hesitation in a number of instances. Several times I was put in harms way as crossing city divided highway, crossing streets and/or dividing highways where that multi-directional traffic lights are not always present. To further explain, realizing the power pickup was not present and turbo did not seem to be 'spun up' even though acceleration was increased dramatically. …

I was driving at 60 MPH when I had to come to a stop because of traffic and the throttle apparently did not disengage causing me to slam on the brakes hard. Only after a few seconds when I stopped did the vehicle downshift and returned to idle function.this has happened before and since this incident.the vehicle has also idled high at times and will not slow down when removing pressure to the fuel pedal.it is as if the throttle assembly sticks which is an apparent electrical malfunction.this is and has become a serious safety issue with this vehicle. I have made a complaint before and contacted Dodge Ram about this with no satisfaction.I will be drafting a registered letter to nhts board and Dodge Ram releasing liability from this issue until it is resolved. …

Chrysler has had NHTSA campaign number: 14V635000 component(s): engine and engine cooling , fuel system, diesel in effect since October 2014. My truck has this recall problem. I continually have engine code p2609 active. I have contacted Chrysler about this and all they will say is that the repair parts are not available. My truck is still under warranty but Chrysler will not repair the truck. Along with the "check engine light", I have a diesel fuel smell entering the passenger compartment at various times. Chrysler will give me no date as to when they will repair this problem. The local dealers say they can do nothing until Chrysler get the repair parts needed. It seems logical that if Chrysler has issued a warranty on a vehicle then they should be able to repair the vehicle.

I received a recall notice in early December 2014 stating that there is an issue with a diesel fuel heater electrical connector on my truck that May lead to o-ring failure and potential fire. I have contacted the dealer twice and as of last contact they have no idea when a "fix" might be available. Since possible fire is the risk and the dealer, initially, did not even know they was/is a recall, I am concerned. The dealer suggested that I contact Chrysler since the dealer knew nothing about it. Since I was talking with the Chrysler dealer that I purchased the vehicle from, I assumed I was talking with Chrysler. It has been over a month since my last contact with them and I have heard nothing to date. Can you help or provide additional information, please.

Dodge has issued a recall from October 7 2014 for recall p65 / nhtsa14v-635 stating that the diesel fuel heater May overheat leak diesel and cause smoke under the hood or catch fire. After having service at the dealer they stated they have no fix yet or parts for this safety issue which May cause a fire, here are their words from their website under recall status for my VIN incomplete but repair parts are not available. This is the second safety issue where Dodge Ram has had a safety issue but no parts the first was the left tie rod where they had no parts available. Why are they allowed to issue safety recalls and have no parts to fix issues that could cause the vehicle to catch on fire or smoke this places people on the road at risk.

I was driving down I 10 today going 70 my truck started vigorously shacking and making my truck run off the road it was all I had to keep from crashing my front end or read end felt like it locked up then I tried pulling off and my truck had little power it took several minutes to get it running right again but every bump I hit the same problem happened I looked underneath my truck and could see fluid coming from my steering column this happened literally at 180000 miles at 86000 miles my 2012 diesel exhaust filter clogged completely up and the dealer said it wasn't covered under the 100000 mile warranty I paid $934 to have it repaired I believe that I have exhaust problem s still too.
