Sierra 1500 8-cyl

I purchased my pickup new in Jan. 2007 and use it to tow an 8X16 trailer w/electric brakes for a part time business throughout the summer. The trailer weighs approx. 6000 lbs. Loaded and the truck is rated for 8,000 lbs. Approximate towing mileage is 3 to 4,000 miles per year. After towing the trailer 200 miles on Sept. 14, 2012 my wife noticed several oil leaks on the asphalt nearby. I suspected something in the differential area and drove to the nearest GMC dealership several miles away. They diagnosed it as a rear brake line and ended up replacing 6' of it along with both rotors and calipers and a brake system flush for a total of $958.76. I'm 66 yrs. Old and have never had a brake line go in any vehicle I've ever owned and I've lived in Massachusetts all my life. My local mechanic just told me this week that the rest of the brake lines are badly corroded and should be replaced asap. This will add another $900 to the entire cost. There is no question in my mind that GM has allowed quality in workmanship on its brake lines to fall through the cracks...and at the public's expense.

Sierra 1500 8-cyl

After filling the tank I drove for several hundred miles and I looked at the tank and it showed I had gas so I kept driving, soon the engine stopped and I was left stranded by my truck and I am disabled. I then had the vehicle towed and the service station found nothing wrong with it other than they added gas and it started and ran fine. I continued to drive the truck and noticed that the gas was not going down on the gauge like it should. One day I got in my truck and started it and the low fuel sensor light came on along with a chime, the (dic) said the fuel was low but I had just filled it up and had only driven a few miles. The low gas light stays on all the time now even when I fill it up along with the service engine light and it will chime every time I start it up. I took the vehicle to a mechanic and he stated it was a worn fuel level sensor and he has had several GM vehicle that have had the same problem. I feel like this is a safety problem especially when you are disabled and have problems getting around in the first place.

I have a 2006 GMC Sierra pick-up truck with less than 20,000 mile on it and have run out of gas twice when the gas gauge reads more than a quarter tank of fuel on the gauge. I just listened to a report on the radio of a possible recall on many GM vehicles with gas gauge problems just like mine. I wish you would look into adding the GM Sierra pick-up to this list for recall.
