Late GM starters are protected with starter overload programming so they achieve longevity throughout the warranty period. Bosch sells some of the worst garbage on the market now. It's no different than Home Depot selling John Deere or Walmart selling name brands. They took what was once a highly revered name and brand stamped it on countless crappy auto parts. I can count on one hand how many of the reman starters I've replaced defective in the last 25 years but I've lost count of the Bosch garbage that has come back, from O2 sensors, to spark plugs, to engine management sensors.
