This is highly subjective and opinionated statement I am going to make but I have experienced with friends, families and co-workers...
There tends to be an under reporting of complaints with some of the supposed "known" reliable brands. They have cars in for work like any other makes but don't seem to see issue in the same light as brands with supposed lower reliability. Maybe they feel shame that what they bought didn't turn out to be the bullet proof design they were sold.
Sorry.. with all the electronics in cars today.. the 300K+ mileage Toyota (or any brand..for vehicles manufactured in last 5 years) is nowhere to be found on a common basis. One can make it get there but a capacitor, relay, solder joint is going to fail in a control unit along the way. It might be cheap to fix in the day if you can find a used one in a wrecking yard... assuming it is a well known fault.
Even a co-workers 2010 Prius failed on him in the middle of the freeway.. he was just able to get it to the side of the road before it completely died. It took a team of Toyota engineers about a month in the shop to figure out what had failed in it. To this day... it is his best car ever... incident forgotten...(and recently he told me it is using a quart of oil every 1500 miles)
Someone else mentioned confirmation bias here... it works both ways. If someone likes the car, they tend to play down the faults. If they dislike the car, they play up benign non-faults.
