I have a bunch of "class action" checks on my wall next to my computer. Lets see....

Bank $0.07

Bank $4.07

Some company I have never heard of $0.01

Bank $2.77

And so on.

I don't want to take them all down to go through them to see the rest of the amounts, but they are all less than $10.00 each.

I never bother to cash them. They are worth more as wallpaper.

Lawyers are the ones that make money from class actions.

We are the ones that pay for it, when we buy the next one.

Agree. Lawyers are the winners money wise. But these suits sometimes do result in a permanent fix. Sometimes.

Looks like you need to change banks, lol. Merry Christmas to you and all the forum members!

The class action lawsuit on the 8 speed transmission hasn't resulted in anything yet and it's been ongoing a few years now.

The problems all seem to be related to the DOD system.

The solution was to rename it AFM.

The next solution was to rename it DFM.

Just keep changing the name, and people wont be able to keep up.

Potential customer: "Now this vehicle doesn't have DOD, right? I heard bad stuff about that."

Salesman: "No DOD was an old system which only affected a couple of vehicles under rare circumstances. The new design is AFM. Its the latest and greatest, and way more reliable. Totally different design, and more fuel efficient than the last design".

Customer falls for it - and 100K miles later, they need to give the dealership $8,000 to fix the engine or trade it in on the new truck that has the newer, more reliable DFM design........

GM basically figured out a way to ensure that their products won't last much longer than the warranty. They would make less money if their rigs lasted too long.

DOD: Displacement on demand.

AFM: Active fuel management.

DFM: Dynamic fuel management.

They are all the same thing, and also an excellent way for the dealership to make money fixing and selling cars.

Ya, that's true - but rotten apples are rotten apples.

They all basically do the same thing.

Variable cylinder displacement through the use of valve lifter manipulation combined with computer programming.

In theory, the engine lifter design is great. On paper its fantastic. In reality, the benefits are non-existent if you calculate the increased maintenance and repair cost requirement of owning such an engine. Then you have to factor in the value of vehicle reliability.

It was a great idea, but GM needs to just let that one die. Stop making variable displacement engines.

No customer every said "I'm sure glad I had that DOD engine!!".

I agree with you, but there are people who try to keep it v4 as much as possible. Given the option, they would even opt to have it run in v4 full time

I don't understand it... but these customers exist none the less.

AFM and DOD the same thing yes. All it was, was a name change.

DFM is not the exact same as AFM. They didn't just "change the name". AFM is 4 specific cylinders that disable for fuel savings. DFM all 8 cylinders have disabling capabilities via 17 different operational configurations from running on 8 to as little as 2 cylinders.

The only thing AFM and DFM share is the lifters and now the control solenoids being mounted directly to each cylinder rather than in a VLOM.

They probably want to do away with it themselves, but that would be admitting that it was a bad design. If this is the case, it seems they could use the supply issue as an excuse. The same way their leaving off features in the newer ones. They could say, due to the parts supply issue, we will no longer be using the dfm, or lifters. We will be going foward with the reliable standard lifters. You may experience a very slight decrease in mpg, but at least you wont have to worry about tearing into the engine after a few thousand miles.
