   We purchased our 2012 Dodge Ram heavy duty with tow package new. At just over 152000 miles, the engine started knocking while on vacation. We were not towing at the time. We put in injector cleaner to try and help the knocking. During our vacation, we were on the freeway when we suddenly lost power, the service engine light popped on, and the engine died. We were literally driving one minute and the next were trying to get out of the traffic lane with no control. We restarted the engine, the knocking had stopped and power was restored. Two days later, another episode of power decrease but with no engine service light. We used premium gas, injector cleaner and listened for the knocking that came and went, to drive home. We were told by our local dealership it is a lifter failure and the truck needs a replacement engine.

   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.

   Recall T79 or 17V-821 or break transmission shift pin stuck in open position. This is the 2nd time this has happened and serious damage has occurred to the vehicle. Dodge won't do anything about it. Vehicle was parked, turned off, no key. I came out of building and it shifted into gear on its own and rolled backwards into a pole.

   I purchased a pair of Treadwright warden tires for the rear of my wife’s truck. In less than 100 miles the tread separated from the casing on one of the tires. I caught it before it completely blew out and have pictures. The replacement they sent has a blown sidewall. I mounted it and a bubble started to form that was 1/2” high and 3” around with just 20psi, operating PSI for the tire is 80PSI. I immediately stopped inflation and contacted Treadwright. They tried to convince me that it was “overlap” and safe to use. I told them it is not over lap and showed them multiple pictures of the tire from different angles to prove it has a blown belt. They still insisted it was a serviceable tire. It’s not and I have pictures. I’ve used Treadwright tires for the last 5 or so years. Over the last year and a half to 2 years I’ve received 6 defective tires. All defects were fatal defects, all being broken belts. That’s 1 out of every 4.5 tires purchased. If I’ve received that many fault tires I can be the only one. On top of that the insistence of Treadwright trying to convince people to use fatally defective tires is negligent, reckless and dangerous.

    While driving, my dodge shut off and it was hard to control my vehicle and come to a safe stop, out of the way of other motorists. Lost all power, as if I turned the key off while driving. Turns out that there is a weak/loss of connection in the WIN module. while the vehicle is running at idle, the truck will shut off as if I turned the key to the off position. This is dangerous and scary. There was no warning or heads up or any issues prior to this incident.

    When driving at highway speed, if I hit the seam between the road and a bridge and it is not smooth my truck goes into a, "Death wobble." The steering wheel and the whole truck shakes uncontrollably. I can barely keep it in the road. It will only stop when the vehicle slows below 30mph. This problem started about 48,000 miles, I only have a little over 56,000 now. I have changed the stabilizer, got new tires and an alignment. I will be taking it to a mechanic on the 17th but I really believe the manufacture should have a recall on this vehicle. It is very dangerous. I am not the only person to own one of these trucks and this happens to.

    The exhaust manifold bolts on both sides of the engine warp due to two different metals being put together under heat. Steel and aluminum expand at different temperatures. This causes the bolts to break off of the exhaust manifold creating an exhaust leak into the engine bay. Yes, this can be inspected upon request. The safety of myself and the general public is at risk due to the exhaust leak into the engine bay being pulled into the cab via the heating or airconditioning system. The exhaust fumes are pulled into the cab of the truck via the heating and airconditioning system. When running, the truck has a very noticeable smell inside the cab. It has caused me headaches as well. This poses a risk to the public if the driver were to pass out from said fumes. The problem can be reproduced and is a known issue with Dodge. It is very well documented online that this problem happens to nearly all Dodge Ram trucks. It has never been recalled because Dodge says its not a "safety" concern. This is very much so a safety issue. The components have been inspected by others, and verified as broken. I will not take it to a dealership to have it inspected as they want to charge 150$/hr to diagnose something that even they recognize as a known issue. There were no warning lamps, messages or any visible indication of this problem. A loud ticking noise and a strong smell of exhaust fumes are what brought the issues to attention.

    My Dodge Ram 2500, 2012 Hemi engine started making a ticking sound so got a tune up. The machinic changed the spark plugs and distributors around after I complained. Nothing he was able to do enable the truck to function properly. I spoke with the Dodge dealership, the spoken informed me that when Dodge merged with MERCEDE the problem persisted and to this date a fix was not provided. I spoke with other Dodge owner who experience the same problem. The engine was not functioning properly because of internal damage. The cost of repair would cost between $8K and $10K to replace or repair the engine. The dealership stated that NHTSA nor Dodge have provided a fix and that the problem still persist to this day.

    Engine has been making a ticking noise on the passenger side for the past few months. The passenger side exhaust manifold warped and broke two bolts in the engine block. This caused an exhaust leak and made the truck run rich due to the leak before oxygen sensor. Fuel efficiency declined. Replaced the exhaust manifold, gasket, and bolts to repair the problem.

    The bolts holding the exhaust manifold to the engine cylinder head, are breaking off. This has occurred in the past, on the drivers and passengers side. I had the problem repaired, by a dealer, which required the replacement of the passenger side cylinder head as well. This issue has re-occurred on the drivers side, which has been confirmed by a Ram dealer, as shown in the attached documentation. In every instance, the issue starts with a tapping noise, as the exhaust manifold pulls away from the head. Passengers in my truck have complained about the smell of exhaust fumes, which is a safety and health issue. This truck only has 85,000 miles, yet this is the 3rd incident of this issue occurring.
