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.

We purchased our car in April 2014 and the part just failed yesterday at only 126,000 miles. We understand that there is a pending class action suit (or perhaps one that was settled) but do not know h…
