Read that GM was sued back in the 1980s over cylinder deactivation issues.Oh, no they didn't... It is pretty much alive and well, in new generation DI engines, with similar problems.

Do you have 5.3l-6.0l V8 GM engines down under?Read that GM was sued back in the 1980s over cylinder deactivation issues.
Have not read any issues here in Oz regarding DI engines and they have been around here for well over a decade now
And this is the point. Only minority users with certain driving habits usually get affected. The vast majority of owners after 5 years should have no issues with normal driving if they also serviced it by following the correct schedule.
For Honda V6 VCM, usually itll take 5 years to have the symptoms.Read that GM was sued back in the 1980s over cylinder deactivation issues.

I thought the reference was to GM lawsuits. GM AFM technology wasn't even there prior to 2000? Or was it 2007, can't recall.
Still, nothing has changed in technology. Same issues...
You just hit the nail in the coffin. Cylinder deactivation applied to a 4-cylinder simply doesnt make any sense for 0 or 1 mpg gain with many potential risks! No wonder its the industry-first on a 4-cylinder claimed by Mazda! (boom04)Good to know, wasn't aware of that. However, this will end with nothing. And will cost a fortune. This is why GM doesn't quit on this technology. At least it has some marginal fuel economy benefits in large V8. Not in 4cyl Skyactiv thought.

I haven't seen any information to suggest that the problems suffered by Honda, GM, and Dodge/Chrysler owners had anything to do with neglect or not following the service schedule. The root cause of the problem exists regardless of whether the oil is clear or dirty.
As far as driving habits go, logic suggests the more time you spend running with cylinder deactivation engaged, the more likely you are to have problems and the earlier they will occur.
At this point, it's anyone's guess whether Mazda has eliminated the problem (doubtful), has gotten it mostly under control (probably), or is going to suffer the same fate as the others who tried it (hopefully not). We'll find out in a few years.

Red MC said it the best, the only solution to overcome the inherent issues is to periodically re-activate the cylinders more often and Honda is doing this for its V6 VCM. But it’d defeat the purpose of cylinder deactivation, and the fuel saving becomes not significant.
A class action suit was filed against GM around a year ago, late 2016/early 2017 time frame.
