Stellantis Hurricane 4!

Did anyone watch Cory's interview with engineer Ashish about the new Hurricane 4 turbo engine? From the video it sounds like Stellantis actually listened to the buyers about the concerns and questions of the turbo four cylinder engines that are going into almost every midsized truck and SUV out there. (They even brought back the dip stick!) I know Engineers love to talk up their babies, but he seems genuinely excited for this ine. Tell me your thoughts. Me? I can't wait to see this in the new Dakota.

 
I specifically asked Cory to ask about carbon build up. Do I think his answer changes anyone's mind? Nope.

My local mechanic friend said they offered carbon build up removal years ago on V6 and V8 engines. Nobody bought the service, so they stopped doing it. And nobody is buying the service now from what I can tell online. You sure hear a LOT about it from online commenters though.

I maintain if it was real concern, dealerships would be offering it left and right as part of a maintenance package as well as every oil shop in the country. You'd get junk mail listing it as a service and all sorts of debate on prices and who does it better online. You just don't see it.
 
The talk of the risk of carbon build up was one of the highlights for me. Right next to the Dip Stick and the thickness of the hardener spray in the cylinders.

That's why I shared it with my dad and why I posted it here. It shows they are listening.

This is going to be a great engine in the Dakota.

People in the industry watch my channel and others. They also look over the comments at times.

A recent example was the changes for the Cummins engine. Doug Killian, the engineer I interviewed, watched the video and then read through the comments. I got the chance to interview Doug on the interview with the 4WD gauge cluster explained. Before recordering, we both discussed the comments on the Cummins video about lifter failure. He was rather shocked at the amount of people talking about it.

So, he followed up with Cummins and I waited until the press drive of the new Ram HD trucks. Then, we filmed the follow-up short (maybe a long-form video) on it.

Long story short, Cummins and Ram had not heard any of the outcry over lifter failure at the level the internet made it seem like a known problem and thousands of failures.

It seems like that is my role more than ever these days. Highlight the issues consumers are facing and get it on the radar of manufacturers who aren't getting the same information from their dealer networks.

I do find the disconnect interesting. Why don't automakers see the same issues the internet sees? Is it due to the viral nature of complaints whereas when one person has a problem that problem gets amplified by the doom and gloom channels? Then, every video gets comments about that problem.

I'd love to see the true data from people who have a problem vs those who just regurgitate the same complaint over and over again because they have a beef with XX automaker. Or they simply hate automakers and love to live in the negative.

New job opening for auto companies. Have people check forms, YT comments, and soc media for common complaints. I'm surprised they haven't done that already.

You're not the only one.
 
I wonder how many times carbon build up happens and is diagnosed as a failed engine, or valves? I think depending on the quality of fuel and oil you use can have a major affect on carbon build up. I get the that manufacturers say they don't see the issue but why would they admit to seeing any issues?

This is what everyone wants to know. Sometimes it seems like dogpiling. Everybody joins in if one person says it, and then that makes it truth. Extremely difficult for a manufacturer to fight that. They may go to all their dealers and collect the data of failures brought in, but the numbers end up being below a threshold that demands action. Then what do they do? On the other hand, when the gov't has to force their hand and demand a recall and it turns into 500K (cough 6.8L cough) trucks, it makes you wonder. Did they have the data and hoped it would just go away?

I've had drinks and off-the-record chats with engineers. They truly don't see the same issues the internet sees.

Examples:

  • Carbon build up
  • Turbos blowing
  • Cummins Lifter issues
  • GM failed lifters and connection with AFM or DFM
  • Oil change interval concerns (I'd wager 95% of people follow the 10k rule, but the 5% are pretty loud about it)
  • New truck quality being garbage - when you look at the failures per 1000 it tells a different story
Recalls = poor quality

Those are just the ones off the top of my head.

I do think a lot of the problem is everyone has more information. 1 failure on the Internet can be seen by 10,000 people easily that didn't used to be the case. Now my problem in particular with carbon build up is that I've had that happen to me personally. But I think those issues have been addressed through the years. I had the issue on a 2013 GMC it also consumed oil. My brother has a 2018 6.2 GMC and loves it.
 
Just finished watching Jason's take on this new I4 from Jeep. I knew it was innovative but didn't really think it was that innovative! To impress Jason with engineering isn't easy. The wild thing I picked up on was the lack of EGR. Didn't notice that from previous videos.

No EGR is actually a big deal. First time hearing about a modern e fine with no EGR.

This one, the GM lifters, is so overblown. If you look around you can find plenty of videos with people who have disabled the AFM and still have a lifter issue so we know there's not a direct correlation. If could be that the type of lifter used to allow AFM/DFM is an issue but it's not the AFM/DFM by itself. I go out of my way to ask every GM guy I run into and I have yet to find someone who has had lifter issues. I'm not saying it doesn't happen, it absolutely does, but at what true rate?

Ram also has just as many lifter issues in there DMS trucks with the HEMI. My father in laws 2016(I think) RAM was toast at pretty low miles because of lifters and he had a similar issue with an earlier year. Shit luck, but I would still feel comfortable buying a RAM if it was the truck I was into.

I could make a whole list of things I think are overblown on the internet. I've had to ignore so much of the noise lately to stay focused on my work it is ridiculous.

If you watch too much YouTube you will come away with these conclusions:

  • Every new truck is junk
  • The amount of recalls = quality has gone downhill
  • You MUST change your oil more often and you MUST use a different brand or type of oil for your engine to last
  • Turbocharged engines are designed to fail
  • Wet oil pump belts are your enemy
  • Engines NEVER use oil and if one does, it is junk
  • ANY use of plastic in an engine means it was poorly designed
  • Carbon build-up is a real maintenance item and must be performed at 60k miles
  • You must change your transmission fluid every 40k miles regardless of how you drive
  • Aftermarket companies will always build superior parts than OEM
If you listened to all of this, you'd never buy a new truck, only buy old trucks and pour all your money into keeping them running.

However, people are buying new trucks in droves, those trucks are doing well for hundreds of thousands of owners and those owners just follow their owner's manual for maintenance like they have done for years. Pretty simple and you don't need to watch a hundred YouTube videos causing analysis paralysis to just enjoy your truck.
