2003 Chevrolet Silverado 2500 Fuel system Problems

“After loaning my daughter my truck we met at a location to exchange vehicles. I started to drive away and applied the brakes and the pedal went to the floor. I pumped the brakes and was unable to achieve any pedal pressure. I had my truck taken to my residence and inspected the brake system for the cause of the failure and found that the left rear steel line rusted through and created a loss of fluid. In my opinion this line rusting out is very premature for the age of the vehicle. …”

“Chronic failure of fuel injectors on 2003 duramax chevy truck, deal has replaced injectors three times, now they are failing again and want 5k to fix them. Last fix was 40,000 miles ago. Here is the short and skinny. I was informed (during an injector swap in my truck) that the different types of injectors that were tested by GM and their partners (isuzu and bosch) provided good data for the ongoing service campaign, but will not be released through GM parts. …”

“When driving the truck whether on a regular street or at high speeds on the highway, the engine suddenly either dies, reduces down to idle speed or idles very roughly. The reduced power signal comes on, along with the engine light. This has happened to us, several times while driving on the highway and on regular streets. We were extremely lucky not to have been killed. I researched this and found that many owners of the 2003 chevy silverado 2500hd had the same problem. We spent a lot of money at penske Chevrolet, and according to them, they don't know how to fix it. …”

“I was driving down the road at highway speed (65mph) and the front right steel brake line burst and I lost most of my brake fluid. Upon looking under the truck for the cause of the problem, I noticed that all of the brake lines and two of the fuel lines were badly corroded. I tow trailers often and I'm thankful I wasn't towing our 11,000lb 5th wheen camper when this happened or there would have been a horrific crash! I have done quite a bit of research and noticed that there are quite a few compliants about the same problem for this model year pickup. …”

“Instrument cluster fuel gauge failure. This happens frequently, sometimes every day. Nothing has been found to correct the failure. The fuel gauge often shows inaccurate fuel level readings. It happens more often when the car is warm than when it is cold. It happens a lot when the car is hot (e.g. Heater is on very high or in the summer). I'm afraid that the fuel gauge will tell me that I have more fuel than I really do and, as a result, cause the engine to stall from fuel exhaustion on a busy highway resulting in an accident. This still happens to the vehicle often. …”
