I work in the 12 volt and 24 volt industry and you bring up very good points....one additional thing to remember is heat is a huge issue when working with electronics. Once things get hot (alternator, wiring, motors, video displays, etc) they can become problematic. Alternators don't put out their specified amperage and voltage....wiring becomes more resistant and electrons don't flow efficiently.....electric motors and video displays consume more power....maybe the battery is getting too hot under certain conditions...who knows?? All of it can lead to a viscous cycle of doom. And if the algorithm for the PCM controlled alternator is wrong, this causes more problems since the alternator can now "shut down" to help with fuel economy. Yikes....it's enough to drive an engineer to drinking.

I have two Range Rovers and the batteries (large 61 pounders) never lasts more than 3.5 years. Modern vehicles (especially luxury models) are amperage killers.

The wife has a 2018 X5 SUV but her prior 2014 X5 was also fine. Even when it's 90F the cabin blower stays on and for a normal length stop light the temp is fine. It will start if it can't maintain the set interior temp. At about 95F is does not shut off.

The only time I shut it off is when in Sport mode which is seldom as the wife is usually with me and I can't push her car or I won't be able to borrow it when needing to hale "stuff!" When by myself I will occasionally use Sport but only to have fun not to shut off Start/Stop.

Well, this explains why no mules have been seen lately. It's been getting colder, and all of them had dead batteries. AAA only gives you three free jumps a year.

Very surprised at the number of people who think an electrical issue could not create a delay in the development and introduction of this vehicle. I think we should be reminded of the length of time it took Honda to get the current NSX ready for production. Honda first announced the new NSX was being developed in 2007 with a projected sale date of 2010. This car employs some of the same hybrid gas and electrical motors tech that the C8 is rumored to include. The NSX took nearly 10 years to get production ready! From 2007 until it's introduction in 2016, people complained the whole way about how long it was taking. When I bought my first Honda back in the early 80's, and compared it to my current at that time, Camaro ... it was clear to me ... These Asian Engineers are some SMART MF's!!! So, ... if GM is building a new supercar with new tech electronic wizardry, and a newly found electrical problem has added a new 6 month delay, ... I find this TOTALLY PLAUSIBLE! Not saying the NSX delays were electrical, .. but whatever, ... they took the time to get it right!, ... so I get it!

I read an article years back that said the electrical systems on vehicles will need to be upgraded to possible at least 24volts. One of the problems with that is the simple use of capable switches. Some, if not most, aircraft use 24 volt switches and they are expensive. I will say that I just replaced the 12 volt battery in a 2009 S550. The original battery still had some life; impressive.

OK, I simply said I've never driven a vehicle that had start/stop and didn't have a disable button. I've never owned a GM product other than Corvette. The start/stop feature works/worked flawlessly in my '15 Jeep and in my '14 Jaguar F-Type. That's all I said.

There's an incredible team working on the next generation Corvette. Whatever issues they are dealing with during testing, they will get worked out as quickly as possible. I find it laughable that some in various social media are knocking the Corvette team because a problem was found during the testing phase. Don't forget, Corvette is the longest running car nameplate in America and is the tip of the spear for Chevrolet technology. The Corvette team isn't going to let us down. Stay tuned!

I think car manufacturers have auto start stop the wrong way. Instead of pressing a button to turn the system off every time you turn on your car, you should press a button to turn the system ON when you turn on your car. If you know you're going to be doing a lot of city driving, or just plain stop and go, then you can press the button when the need arises. I know a lot of the auto start stop delete kits have it working this way so if you want to turn the system on, you press the button that used to turn the system off.

I am sure they feel...we need to be protected from ourselves... ; )

Exactly. That's what testing is for. GM didn't promise the car by a certain date. It will get here when it's ready. Much better to work out the kinks now than later. If GM changed their mind on a design, then that's their prerogative. I'm sure it will be a better car for it.

Honda only has themselves to blame for that. They changed it from an off the shelf, transverse NA V6 (like the original NSX) to a clean sheet longitudinal twin turbo V6 midway through the project.

I notice you're no longer posting your usual line of "everything is fine and the car is on the original schedule and nothing is delayed and everything is awesome and the Corvette team is the bestest and it'll all be on time I promise and pinky swear".

Yeah, but this is really embarrassing (from Jalopnik):
"A source speaking to Jalopnik, also on condition of anonymity, elaborated on the issue further, claiming GM began developing the mid-engine sports car with a wiring harness and electrical system found across GM’s current lineup, only to determine that it needed to swap it out for a newer, more capable electrical system deep into the development process."

Lucky you.

Aircraft use 28v, not 24v. Anything aviation is expensive due to requirements for air worthiness.

If you lose an alternator on a car, you can pull over miles down the road before your battery drains. Problems are a lot worse 13k feet in rhe air.

Redesign of wire harness, testing and new production would take 6 months.

Flux Capacitor is undersized. Needs a little redesign.

The HACK

My understanding of electrical engineering is limited, but I believe the impetus to move to 24V was that, as current draw increases with today's added electrical component demands, wiring harnesses will have to get bigger, thicker, and HEAVIER and more expensive. That it's cheaper and easier to move to 24V and keep the wiring harnesses the same gauge to keep weight and cost down and still drive enough current through.

Problem is, of course, that all the electrical components will all have to be designed to accept 24V current, or have some sort of additional transformer to step back down to 12V which defeats the purpose.
