| Steering problems |
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. This time I went to an independent shop as they were $1000 cheaper and stated these upgraded injectors should last 150000 miles not 50000. Had to have power steering hoses replaced again also along with power brake servo because they were leaking again at 157000 miles. I have all of this documented in writing by service depts.
Power steering cooler and lines rusted through and leaking, engine oil cooler lines rusted through and leaking, transmission oil cooler lines rusted through and leaking. All had to be replaced. Work donea t GMC dealer.
Many components under the truck are severely rusted. Two brake lines failed in August 2011 due to rust. The rest are ready to fail soon. The power steering line rusted out this month (December). Rust at sensors of abs system causes erratic abs operation.
Brakes are spongy not right power steering whines as do brakes.
