Not sure who, but someone's Rebel died on the road after just 2 months of use. Apparently it had a ceased / locked up motor. Is this common?

Yea, you can see those tires getting forcibly dragged onto the bed, not something you want to see on relatively new tires. And they couldn't get it into neutral either. Just a heads up if anyone comes across this:



I found the guy on a ram forum, apparently he heard a grinding sound before the truck died and there was a strong electrical smell. He tried to turn it on again and there was a loud whistle, clunk and then the smell of wires.

Turns out, the smell was from the alternator burning up when the engine locked. The cause was a dropped valve in cylinder #5 and the piston crushed it. Poor guy needs to have the entire engine replaced along with the starter. At this point, he may as well ask for a new rebel.

Holy moly thats horrible. Definitely may as well get it replaced. That's messed up, especially after 2 months of use... any mileage that we know of ??

It's a known (but relatively rare) occurrence with the smaller engines < 6L. Overheating in the head can cause valve seats to drop, and it goes downhill from there.

Thankfully it's relatively rare. Still sucks to see someone having to deal with this. Do you know how the dealers have taken care of prior situations like this ? Replacement engine or repairs ?

Good to know that this was one of those rare cases. Would opening up the hood vent like this guy (http://www.ramrebelforum.com/forum/what-did-you-do-your-ram-rebel-today/2994-working-hood-vents.html) lower the risk of this happening since it's an overheating problem?
Honestly don't have an answer. There are a lot of speculations about what's causing it, and "fixes." The most common are:

Material issues and poor oil circulation design There are claims that the oil holes in the heads restrict flow, preventing proper cooling. Keep oil topped off to help.

MDS causes uneven heating in the heads which could exacerbate the problem. You can't have MDT without uneven heating so that's no surprise. Run without MDS, drive it as if you just stole it. Or just shut the MDS off with your gear shifter a few minutes before your trip is over, especially if you've been cruising at highway speeds with MDS active. Helps equalize the temps.

Clogged fuel injectors can cause cylinders to run leaner/hotter.

Heads are aluminum and seats are steel, so heads expand faster under heat and seats fall out. Using more valves means smaller seats, and smaller pieces reduce the expansion issue.

Happens mostly when engine was shut down after getting really hot, then restarted. When it's really hot, let it idle a couple of minutes to help cool it down and let the heads and seats equalize.

Again, these are all speculation and FCA has never acknowledged this as a problem, although there are enough dropped seats over the years... mostly since MDS was developed.
