Scotty , like your program ! Have a 2021 Mazda 3  automatic  w/ just over 40, 000 km purchased new from dealership .Bought a 2021 instead of 2022  because 22's had too much safety  crap that couldn't be shut off  .Had an issues w/ a sensor  ( thermostat ) that had to be repaired @  30 K  kilometers .Indicator light  in dash .Then  had  this happen  ( 3 times )  when vehicle wouldn't start .  Foot on brake  , couldn't depress pedal at all , engine refused to start . Taken to dealer  fob batteries replaced and new sensor  installed ( under warranty )  problem gone  . Then same  issue today reappeared  yesterday.

Veh starting N/S  . Pushed on Fob  door lock & unlock and car worked  ( bad words used )  Misses had  veh today  . Same orginal issue .Brake pedal  locked up when  foot on  brake before attempt to start . Fob  within car and close by . No start  . Wait approx 15 min  , attempt again , car starts .

Car driven approx 10 km  and stopped  for  several min . Exact same starting  issue . Wait 15 min , car starts now at dealership  for them to assess .

Any ideas   ?   Vehicle haunted ? 🙂   Had 2007 Carolla  manual w/ 380 K that always started regardless of season  . Was I wrong to buy a Mazda ?  Thanks for any insight

Well unfortunately cars are so complex these days. The starting of the car involves computer modules relays all kinds of stuff. Realize that when you try to start the car it just sends a 5 volt reference signal to computers. It is so freaking complex. It would make your head spin. But it's 2021 if you still be under warranty
