Everyone should have one of these at home
https://en.wikipedia.org/wiki/Infrared_thermometer . After a drive immediately check the brake rotor temps through the wheel spokes, if possible, or even the wheel itself by the lug bolts (same place on every wheel). If you have a sticking caliper (or even a worn bearing, but less obvious until it gets bad) you will see a noticeable temp spike.
Ravinder is having a similar problem, isn't he? Do these cars have a limited slip differential?
