For about many months now I have had what sounds like a Exhaust Manifold leak. I have been trying to learn more about it. I have a 19' Ram 1500 Laramie and I have found that this is an incredibly common issue amongst Ram owners with a 5.7L V8 Engine. You tube has thousands of videos about how to repair, there are hundreds of message boards online, and even my mechanic said to me "Oh yeah I've fixed hundreds of this issue on Rams". When I remote start my truck I have to roll the windows down when I get in to let the exhaust smell out of my truck. I would assume that the air intake for the cabin climate control is pulling in the fumes from the engine bay. It concerns me to leave my truck run too long while not moving for fear of passing out. When I took it to an exhaust shop he said he could temporarily remedy this with some liquid gasket maker but he was right, it only lasted about 2 weeks. THIS NEEDS TO BE A SAFETY RECALL. I checked with my dealer service dept and he quoted me "at least $1,600" I can buy an entirely new aftermarket system for less than that. I am about 20k miles out of my warranty. This needs addressed.

The driver reported loud sounds coming from the engine bay and an exhaust smell inside the cab. He mentioned that he passed out due to the fumes entering the cab during a warm up of the truck. An inspection revealed several issues with the exhaust manifold, including cracked manifolds and broken bolts. The cost of repairs was too high for the owner, as it would exceed $2,000.

I started smelling exhaust fumes in the cab of my truck. I began inspecting the engine compartment and heard a noise from the left side of the engine. I also noticed reduced power from the engine and a puffing sound during hard acceleration. I researched online and found numerous complaints for the RAM 1500 truck with the 5.7 liter hemi engine manifold exhaust bolt shearing and manifold cracking. I took my vehicle to a RAM dealership. The left (driver) exhaust manifold was replaced due to a sheared center bolt and a cracked exhaust manifold. The crack went almost completely around the center of the part. Technical Service Bulletin (TSB) 09-011-22, dated September 3, 2022 was issued for this defect for 2019-2021 RAMs with 5.7 liter engine. The dealership bill was $833.06, including $260 ($217 MSRP on MOPAR.com) for the kit and $525 for labor (2.5 hours per the service representative, so $210 per hour). This known defect is a serious safety issue due to exhaust fumes entering the vehicle cab and being breathed by the driver. A recall should be issued for this defect.

There is a ticking noise I hear when the truck is first started and it is very obvious until the engine warms up and then it is less noticeable. I also noticed a decrease in fuel mileage. I had a mechanic look at it and he told me that the right side exhaust manifold was cracked. I ordered the right side manifold and new bolts and had the mechanic install them for me. Once it was installed when we started the truck the noise was still present but not as loud. I had him look at it again thinking that maybe the install was not done correctly and he said the left one was cracked as well. He showed me the crack. I got online and tried to order the left manifold but it was backordered. I told him that I couldn't find one and that I was on a waitlist at one of the dealerships for it. He told me I needed to try to get it ordered as soon as possible because further cracking could cause issues in the engine and cause a catastrophic event and ruin the engine. A year and a half later there are still no parts available. Upon further investigation I have found that this is a common event for these engines and has been for a very long time. The reason the parts are on backorder is because it is happening to most of the trucks with these engines. Also there is not a replacement part that fixes this issue so there are lots of posts online about it happening a second time after replacing the cracked manifold. The only alternative is to change the OEM manifolds out for shorty headers, which is a lot more expensive, and from the looks of it they are on backorder as well now. It's also a safety hazard because all the exhaust fumes leaking out can get into the cabin and cause carbon monoxide poisoning, accidents, deaths, etc. This is unacceptable. A recall needs to be issued and these vehicles need to be repaired at Chrysler's expense no matter the mileage. The worst part is that people agreeing to repair it can't because the parts are on an extended backorder with no ETA.

Broken exhaust manifold bolt warped the exhaust manifolds. Exhaust fumes can enter the engine compartment using the recirculation button. This is a known Hemi issue for years

Well the other day I could smell a strong odor coming from the hood of my 2019 Ram. I started feeling a little woozy and light headed from the amount of exhaust fumes coming from the engine. I later investigated the smell and found that the engine was also making a loud ticking noise as well. I decided to tear down the vehicle and found that both exhaust manifolds were cracked in the same exact spot. Now the only way something like that can occur is either bad design, bad casting at the factory, or bad material used in casting. That would make Ram 100 % responsible for this defect. I'm not a scientist, but I would have to think that those gases escaping into the atmosphere would not be passing through the catalytic converter. If our planet is in a global warming crises that can't be helping out our atmosphere at all. I think Ram needs to replace every vehicle that has the same issue immediately. If not, no telling what affects this is making on our planet and the safety of everyone on it. Also a cracked manifold can cause engine problems like overheating and I would think an over heated engine can cease up and stop running. Now if someone were traveling at a speed of 70mph and the engine overheated and locked up, could possibly cause a fatality!
