A question and then a couple of comments:
Since Lexuses are made by Toyota, will or do they have the same issues?
My wife’s Lexus 300 is 15+ years old. It and my getting gray time wise Honda Ridgeline have minimal if any electronic gear. Their doors can be unlocked or locked with the remote and the trunk on my wife’s Lexus.
We keep getting offers to buy our vehicles from smog station people, the national tire service place where we have both vehicles serviced, neighbors and people we don’t know.
One of our sons got an early inheritance of our OJ Simpson Bronco model. He has gotten offers to buy it off and on in the past decade. It recently passed the Ca. smog test, and he got 2 offers before he left the station. After it passed the smog test, he gets offers from strangers and people he knows and long term neighbors. The little year sticker on the rear license plate going out 2 years must be the “tell”!
I know of LOTS of friends and coworkers getting offers for their pre-HAL vehicles, and the frequency has cranked up since supply chain problems crystallized.
It's real easy to run paranoid scenarios, where the government remotely drives you and your car off a cliff or turns off your homes' utilities because of a bad social credit score. It's always possible - the technology is there. Plausible? At this time, probably not because there are still too many people - centrists AND Deplorables - who'd be impacted and peeved. After all, even Statists don't want to die.
But running scenario analysis is a core element of any risk management function. And as they say, just because you're paranoid doesn't mean they aren't coming after you.
Scotty Kilmer's favorite car claims they run 3 or 400,000 with out a problem if you keep them serviced. I have owned several Toyotas and never had to have one of them repaired other than tires and battery. I have a new Highlander but prefer my 2001 Ford expedition, personally but wife like the Highlander it does have some cool features and comes with 10 year 100 thousand mile bumper to bumper warranty, since I am 83 I won't ever have to repair anything on it never even looked under the hood or anything else. My Ford will likely outlive me without a warranty.
