I guess the question is - what is "long term"?
Long term, anything past warranty, definitely past 5yr/100k. Average age of the US car populatiob is over 11yrs now.
I just don't understand why every manufacturer is moving towards direct injection if it is so problematic over what I would consider a reasonable timeframe (100k-150k miles).
Emissions, power density. plain and simple.
In my experience, most people don't keep their cars over 150k miles, so if they are generally just as reliable overall up to 150k miles, then I can understand the move towards direct injection.
Original owners my not keep them, but the huge majority of cars on the road have over 100k on them
Direct injection gives you more power and better fuel economy, but those gains are minimal. I just don't understand why direct injection is so popular if it's really that problematic.
Because its the only way they can meet regulatory targets.
But that wasn't my question anyway... The question was do you think GM cars
are more or less reliable overall than they were 10 years ago (not the engine specifically, but the cars overall). If you truly believe that the cars are generally less reliable now than they were 10 years ago, then that is very problematic, in my opinion.
Hard to say. On the face of it, NO, they arent more reliable. They break more, they have more issues, there are more complaints than there were in 2005. This has the caveat that people now expect more from their vehicles, we live in an ever increasing "I need it free" society, and the cars are simply more complex and have more thing to go wrong. See the threads regarding features feel vehicles are "missing", and things like infotainment functionality and peoples expectations of what a car should do now.
As a society we have forgotten what REALLY used to be involved in owning and operating an automobile, how much it cost to maintain, what characteristics and condition were considered acceptable and how long a vehicle should last with no money spent on it, and how long the manufacturer should be expected to be responsible for taking care of it.
Again, the timeframe that we're talking about here is important too. Why would every car company purposely move towards technology that is more problematic and more expensive for them to warranty over a reasonable "lifetime"? It just doesn't make any sense for a few extra HP and a few more MPG.
It does if you cant continue to sell vehicles because you dont meet the requirements.
