I understand GM had a recall on the brake booster sytem and also a few years back a recall on replacing all the fuel injectors on the diesel engine ! I am oringinal owner at the same address when I purchased the vehicle new ! I missed the recalls because I never was notified ! its sad to buy a GM product and they don't alert me to a recall ! what's up with this?
