I bought one of these. It caused a rough 2-1 downshift. I called Range Technology and they were aware on some trucks this happens. I sold the device.

My A/C Condenser went out a few weeks ago at 80k miles. GM paid the entire cost. Had it fixed the following day after it went belly up. They even paid my for rental Charger which I had for a few hours. Yes that was a major issue in the 2015-2017 models. Yes it is a nasty Sauna here 24/7. Now that the rainy season started it is even worse.

Based on our fleet use of these engines in Silverado PU's I seriously doubt the mileage is increased 2 mpg for the average driver! The newer ones you cannot even tell if it's on or off.

The problem is, with trucks there is no good choice. I've been putting off getting a new truck. Ford has had timing chain issues, gm has had afm issues, ram also has lifter mds camshaft failures. I would use that until warranty is out then do mechanical delete.
And combined how many of these issues what percentage actually affect consumers? You likely have a better chance of blowing a tire tonight than having a issue.

So get a gas 3/4 ton or up. You can get them for the same price as a half ton, better everything (except MPG) with the gas motor and Ford and GM do not have AFM in their 3/4 ton and up gassers.
You cant get a comparably equipped one for the same price. You have to go down at least one trim level to get one near a half-ton price.

Which is fine is just shows a lack of understanding how manufacturing works. If you compared the big GM, Ford, and Ram units sold with issues compared to Toyota units sold the amounts would be within 2 or 1 percentage points of all makes combined.

Many thanks. I just know from experience that almost every mass producer has a few lemons in the mix. Nobody makes perfect cars every time in true mass production volumes.

Not a diesel but the gas ones sell for about the same out here. Most people want the diesel so will deal on the gasser. When I was looking they had two LTZs on the lot one 1/2 gasser one 3/4 ton gasser there was 580 dollars between the two. 53,000ish each. the diesel LT was 63,000.

That is all LS based engines over a long period of time. That O-ring is not the main reason for the lifter failure. That would mean you see it often in stuff like the 5.3 or 6.0 prior to 07 or an LS1, that is not the case. While oil pressure issues are the problem it is usually in the VLOM. Failure of the o-ring will cause an overall loss or lowering of oil pressure. A failure or "clog" in the VLOM is generally what causes a specific lifter failure.
This mostly makes my point. The o-ring failure may have been a problem in pre AFM engines, but they did not have collapsible lifters that relied on oil pressure. So pre AFM engines could get by with less oil pressure. Tick and rattle, but survive. Whereas the AFM lifters would get stuck and grenade the cam lobe when there was not enough oil pressure. Sure a clog might be a problem also. Which is also a lack of oil pressure. But that would mean every engine that fails is dirty. Which is not the case. The only common theme is low oil pressure and that's why I think it's the ring more than anything else.

the answer to this is to not buy a truck with afm . if enough people do this mabey they will stop forcing this unneeded tech down our throats .

A 12 year old design plagued with a recall every other month is not a indication of reliability. The truck is losing market share month over month so most consumers do not consider Tundra reliability to be significantly higher than anything else. The consumer is right.
