Hi all: My wife recently took our 08 Sienna with about 35,000 miles to the dealership for an oil change and they told her the front disk brake pads were worn to the point that replacement was needed. The vehicle has been driven conservatively and so-far we're not hearing the scraping/screeching noises that the worn-brake warning alert system is supposed to make when that condition develops.
Is it common for the warning system to malfunction and fail to provide the worn pad alert? Or was the dealer trying to sell my wife a brake job that we don't yet need? Thanks!
