Turn Signal Switch problems of the 1999 Chevrolet Malibu

This is the 2nd chevy that I've owned whose brake lights fail (center brake light continues to work) to illuminate due to a faulty turn signal switch. Although the turn signal, cruise control, wiper control, etc. Work fine, there is something internal to this turn signal/multi-function switch that suddenly causes the left and right brake lights to not illuminate. The driver is unaware of the problem until another driver on the road brings it to their attention. There are numerous gm car owners who complain of the same problem on the internet, yet gm has not offered to replace this switch for the owner. The dealer wants $170 for the part and charge 2 hours labor at $90/hour for a whopping cost of $350 + tax and only offer a 12-month warranty for their parts/labor. To me, this is a very unsafe condition that gm fails to recognize by recalling or simply repairing free of charge. Apparently, gm says the left/right brake light switch is wired through the multi-function/turn signal switch so the cruise control will cancel once the brake pedal is pressed, but that feature still works even though the brake lights don't illuminate! other car manufacturers' cruise control switches off when the brake is pressed, yet they don't have the issue of the multi-function/turn signal switch failing internally causing the left/right brake light to not illuminate. Please do whatever you can to get gm to replace this poorly designed switch, free of charge to the customer. It should be noted that both this 99 Malibu and 96 monte carlo were both very well cared for by us and still, these brake lights failed with less than 100k miles. Thank you.
