The description of the problem sounds simple: “During installation of the contact-type stop lamp switch on one of the North American assembly lines, silicon grease may have reached the inside of the switch and caused an increase in electrical resistance,” says Toyota, in a release. Although the assembly issue itself has nothing to do with stopping ability, the consequences could be wide-ranging: warning lamps on the dash; a shift lever that might not shift from 'Park;' stop lamps that don't work; or a failure for the vehicle to start.
Toyota is still waiting on the replacement parts, but it will notify owners of affected vehicles soon, via first-class mail. According to Toyota, the repair will take about 30 minutes.
