One day I went to stop on a dry road and when I was almost stop the brake pedal dropped and the ABS engaged. I had the brakes inspected and all of the rotors were almost gone from rust with chunks of the rotor missing on the rear. I had all of the rotors replace with new pads and I still have the same problems with the ABS engaging about 5 MPH when stopping increasing my stopping distance. I have no ABS light or check engine light.

The check engine light came on the first time I was accelerating going up a mountain highway ; it was not a very steep grade but the cruise control was not worth using. The engine is a v-8. I had it looked at a dealership . They found nothing and could not get the light to come back on. After a few days it was back on. The check engine light would go out over night because it was not on when I started driving to work and then after a while it would come on. I have changed oil , air filters and had mechanics clean the sensor. It will go out for a few miles and then come back on. Once it has started coming on after a few miles it will come as soon as I start the engine every time. As I have driven the truck now for 109,000 + miles the light stays on. It does not seem to mean anything but, I always wonder in the back of my mind..."is this the time that the check engine light really is warning me?" I have read on some websites that this is a common thing for the 2004 1500 silverado but that chevrolet charges $1,000 + to fix it. This is the only complaint I have about my 2004 chevy silverado. This is my 6th chevy truck.

Vehicle speeds up, surges, then starts to buck and you get transmission lash. It happens at road and highway speeds of 45 or 55 MPH, and can/does happen in od or in 3rd gear. (automatic transmission). I have had a third party "scan" the system, and I get "no" codes. Check engine light does "not" come on. I am able to replicate the issue at will. The vehicle is a 2004 k1500 with 46,500 miles. Its primary use since I purchased this vehicle new is to tow a 19 foot mastercraft from april to november. Maintenance is performed by the manufactures' recommended guidelines. Orginal tires, air and oil filters have been changed as needed. No aftermarket devices installed. I have had a couple of verbal encounters with chevy dealer service department. They seem to be clueless. But are willing to troubleshoot at my expense, plus costs of all parts and service hours. This could $1000.00 or more....very frustrating. This is a hazard, accident waiting to happen. I have seen several similiar issues on the internet blog sites, with no concrete answers. Gm is scamming the public, and the gm service departments are passing the costs to the consumers. There should be a recall and a fix for this issue.

My 2004 chevy envoy has a crack in the neck of the fuel tank. The service engine soon light was on last year and I took it to thomas chevrolet in west chester, pa who replaced the gas cap. The light came back on and I out of frustration I waited until my inspection check to have it repaired. Upon taking it to a local mechanic recently they replaced a solenoid which made the check engine light go off. However within a week it came back on. Today I was told of the problem with the crack in the fuel tank after they performed more diagnostic tests. This seems like it could be a problem from the manufacturer (gm) and also poses a safety issue. Fuel can be smelled when standing outside the vehicle. I am concerned about the safety risk this could pose if this is a problem noted in other vehicles. My on-line research indicates the chevy trailblazer had issues with fuel tank cracks. I don't know what I could have done to prevent this problem or even cause it, therefore I would expect the dealership would be held accountable.

'04 chevrolet k1500 - throttle body sensor the issue is that the truck keeps coming in and out of "reduced power mode" which when it is in this mode it is very hard to maintain speed which in turn is inherently dangerous. In '07 I had the connections cleaned and repaired (under warranty), on july 7th of '08 I had the whole throttle body sensor replaced (out of warranty), and it started acting up again on june 25th of this year. I qualified for the 12 month repair warranty, but had driven over 12,000 miles. Out of the blue my truck goes into reduced power mode. I pull over and basically restart the truck a few times and apparently the computer resets and exits the mode. This worked for the first week but now it has to sit overnight. The check engine light will stay on for a day or so, but then will clear. I have taken it to three dealerships for diagnostics and no one can put their finger on the specific problem. The most current one has told me he could replace the throttle body sensor, but can't guarantee that will fix it. He has three more '04 chevys coming in and out of the shop with the same problem. What they have been able to tell me is shown below, but still haven't been able to fix it. "scan revealed 2 p2135- throttle position sensors 1-2 correlation. " using your site I have found the following service bulletin: 060604026 (the federal safety agency item number : 10020835). I don't mind spending the money for the repair, I just need to know what I need fixed. I'm worried about pulling onto the highway and then loosing power and causing a wreck.
