Unfortunately, most shop and most DIY service is done wrong, if at all.
That's is why I qualified reliability with "Properly Maintained".
I don't post much of what I find, others have messed up maintaining these days. Just to busy correcting the mess ups.
Toyota gave us a PM schedule. Follow it with the FSM in hand. Than they're very reliable, derivable anywhere, most any road condition on or off road and most any weather.
~20 year now and only thing I drive. In that time, I did fail to start once. Bad alternate. Which served me right, for driving around for 2 winters without #1 & #2 understandings to protect it. Took all of 5 minutes to pop in new battery, back on road. New alternate took another hour to install, later that day. I could,'t have been luckier. I was at Toyota Dealership at the time. Parts guys lent me a new battery and alternator, which I paid for once sure I needed and installed.
