Had injectors replaced under warranty at 50000 miles after noticing excess exhaust smoke on startup and also power steering hoses were leaking, again at 105000 miles they totally failed as I was bringing my wife home from hospital on I-15 in ca. Up cajon pass and had to be towed to dealer, but GM dealer would not cover injectors under warranty as truck was11 years old and their coverage was for 7 years only, now again had to have them replaced at 147000 miles because of excessive smoke on startup.
