There's just too much technology in all vehicles. My TPM went haywire the other day; all tires, including the spare had 35 psi. I lowered the spare, put even more air in, raised it back up, did a couple ignition resets (should we call it reboot?) and the indicator went out. We all are lead to believe in the "Legendary Toyota Reliability". That's just marketing crap; sells more vehicles, doesn't it? This is my 3rd Toyota, the first 2 were not trouble-free. I bought the Tacoma because it still beats the competition. They are all machines and machines breakdown and need maintenance.
