Open the full vehicle complaint log (all categories)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.
Exhaust Manifold on passenger side is leaking. It has a broken bolt due to manifold warping. This is causing exhaust to leak into the cab.

WE TOOK OUR TRUCK TO THE DEALERSHIP FOR A BRAKE RECALL. AFTER THE RECALL WAS FIXED, MY DAD WAS DRIVING HOME ON THE FREEWAY WITH MY TRUCK WHEN MY CHECK ENGINE LIGHT STARTED FLASHING AND BLINKING. IT WAS ALMOST IMMEDIATELY AFTER THAT THE TRUCK STARTED TO SHAKE AND WAS HAVING A HARD TIME ACCELERATING. HE GOT THE TRUCK TO MY HOUSE. I DROVE IT STRAIGHT TO THE MECHANIC A FEW MILES FROM MY HOUSE AND EXPERIENCED THE SAME ISSUES. WHENEVER I WOULD SLOW DOWN THE TRUCK WOULD START SHAKING.
