In owners' own words
When I start the car and it becomes idle the brake pedal becomes stiff and gets stuck. I have to put the car back in park and restart it for the brake to work properly. This doesn't happen all the time but happens enough for me to be concerned. I took it to two Toyota dealers and they couldn't duplicate it and couldn't find a problem but it is still happening. This only happens when I start car not while driving. Service brakes · reported at 77,000 miles

the brakes have not failed yet, but there is a known issue with the brake booster on my model year. I would like to have the government force Toyota to guarantee the brakes for a longer period of time. currently Toyota has extended the warranty out 10 years / 150k miles from date of first use. Since these cars last so long, this should be 20 years / 300k miles from date of first use. Service brakes
