    The switch to start the vehicle has to be pushed down and turned at the same time. Vehicle starts but shuts the engine down when the key returns sometimes. On one occasion vehicle shut down while driving.

    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.
