FYI the millenial Grand Tour team did an episode on Kei cars and apparently they are not legal in every state. They wanted to take them to pikes peak and had issues getting there. Clarkson would have told them to fuck off and or not driven one.
AFM/DOD is dogshit in the 5.3. I had collapsed lifters grenade my engine at just over 100k miles.

I have a button that disables it, have to press it every damn time though. No more than I drive, I don't see 100K anytime in the next decade. I'm not even at 50K now.AFM/DOD is dogshit in the 5.3. I had collapsed lifters grenade my engine at just over 100k miles.
I'd look into one of the products that disables that crap (there are cheaper than what I linked, but I trust that company to put out quality) and eventually replacing cams/lifters to permanently disable it.

Start/Stop is annoying, but cylinder deactivation is the reliability killer. I don't think there's a button to turn it off (except stuff like tow mode, but then I think you lose your overdrive gear).
You read the part about not getting another one and not driving that much right? PS I don't tow stuff.
If you're not getting another one, all the more reason to do everything in your power to help prevent if from grenading itself. In my opinion, a cheap dongle that prevents the cylinder deactivation system from working is worth it - I wish I would have gotten one. I brought up tow mode because it's one way to turn off the system without a dongle.
yeah I had a Chrysler 300C and 4 of the cylinders would deactivate if you were not accelerating , I had zero issues with it. That start/stop shit is annoying and I am glad I have an override. My wife's car does not , it's annoying and it's already ate a battery and starter.
it's right up there with the seatbelts where the shoulder strap was on a rail because the gvmnt said you WILL wear a belt. So most people didn't put the lap belt on which is worse. I had a car where that belt was bolted in , then they added a clip, then eventually realized it was stupid. start/stop will be the same.
Look into how the charging system in an automobile works and you'll have your answer.
I worked at GM for 6 years. While I didn't work on cars or anything I was aware of the org structure.
Watched a video with former Ford engineer, and he said it was difficult to keep track of software because they used supplier software in their cars. Seat maker has its own software to interface that may/may not be made to spec. Multiply this across all components they outsource and the problem becomes pretty clear. Not only that, revisions in hardware don't always mesh with software versions.
