2003 Chevrolet Silverado 2500 HD Reviews
Great Truck!!! I have a six speed stick and at 190K, it still avg about 20 MPG. I remember a recall in 2006, the dealer replaced the fuel injectors. Since 2008, when someone got in and stole the stereo/ tore the dash apart - it has had a few electrical issues. Replaced the transmission at 189K, finally time to get a new set of glo plugs at 190k. Overall my total avg cost has been .65 cents a mile. My last truck was a dodge ram V10 which cost me $1.00 per mile.
2003 Duramax, now has 157xxx miles. I love this truck but during the last year, which is not bad, I've had the following issues:
Fuel Injectors at 133k
Glow Plugs - Every winter like clock-work it needed one glow every January. There is still one that has not been replaced. But each time a glow plug was replaced the truck ran better.
I bought it with 68k miles. I rated the engine low because of fuel injector issues.
LEAKING DIESEL FUEL IN THE ENGINE BLOCK. This is caused by leaky/faulty fuel injectors. When the injectors go bad they leak diesel in the block. That is when I finally needed to swap the injectors. My engine oil levels were increasing and smelling like you know what?
change engine oil light when you turn it on 10 Seconds or so then goes off twice while driving runs good but never came on before and oil was just change what could it be???????

I have a 2003 2500HD 6.0 liter with 170K miles. The Low Oil Pressure indicator comes on the display and the "alert sound" starts. I have replaced the oil sensor and this still occurs after driving more than five miles. When driving the oil pressure guage goes up and when I slow down the oil pressure goes down and then the sound alert starts again. The truck had a oil change and no oil leaks.
I have a 2003 2500HD 6.0 liter with over 60K miles. Their was a recall on the Dash console, Had that replaced 2 years ago and now the number lights for the mileage only is aluminated when it is hot out, it is still keeping the miles but you just cant see it until it is hot out, anyone else have this problem?
