general problems of the 2004 Chevrolet Colorado

Idle control via electronic throttle body raises rpm very high when the accelerator pedal is not depressed, causing uncontrolled acceleration of vehicle during coasting or when brake pedal is applied. Turning the vehicle off with the key is the only action that has resulted in a cessation of extremely high idle. After restarting the vehicle, the symptom is gone and the vehicle operates normally. This behavior is erratic and inconsistent, the problem has been difficult to duplicate during diagnosis. All testing and inspection of the electronic throttle body, wiring harness, connectors, and functions within the engine computer has shown no defect or indication that a wiring fault, dirty throttle body, or other "wear and tear" item is the cause of this intermittent revving at idle. The most recent event occurred on August 9th 2017. This has been occuring for at least 6 months, on average once a month in frequency.

The ignition will not start at first. It takes multiple times in order to get the engine to turn over. Once the ignition does cause the engine to turn over, the vehicle will suddenly lose power while driving as the vehicle shuts itself off (as if the ignition has been turned off although it has not been). This has happened on multiple occasions in the course of normal driving activities, several times while crossing busy intersections which luckily has not resulted in any crashes to date, but may very well result in a potentially fatal one should it continue to occur. Engine has been tested and all systems check out, except for the ignition switch which -will- have to be replaced.

Everyday now when I try to start the truck it turns over but will not start, wait 15 minutes then it will start. Today when I tried it the first time it turned over but would not start so when I turned it off at the key it stopped then tried to start again on its own for about 8 to 10 secs. The starter turned the engine over without touching the ignition switch it then stopped for about 3 or 4 secs then tried to start on its own again without touching the key, it did this start sequence 3 times in a row. The gm passlock system is terribly defective as reported by all the reports online and I believe my problems are a result of this system.

With the revelation of the gm ignition recall problem, there are much more ignition problems that were not included in the recall. The problem is in the ignition cylinder and alignment with the passlock or passkey sensor. My problem started shortly after the vehicle went out of warranty and I was told by the dealer that it was a $1000. 00 repair. I can not afford $1000. So I have lived with it. Because of the misalignment it causes the ignition to think that the vehicle is stolen and disables the fuel injectors, it has left me stranded quite a few times along the road waiting for the computer to manually reset after 10 minutes, it has also cost me several towing bills until I did an internet search and found out how widespread this issue is. If the misalignment is causing this to happen what will it affect as the problem worsens. This issue is not covered by the current recall but deserves investigating . Thank you bob.

The contact owns a 2004 Chevrolet Colorado. The contact was driving approximately 45-65 mph when a total loss of engine power occurred with the illumination of the engine warning indicator. The contact was able to restart the vehicle after waiting a few moments and resetting the codes. The vehicle was taken to an authorized dealer and repaired. The failure persisted. The vehicle was taken to the dealer four times with no resolution. In addition, the battery was replaced. The vehicle was not further repaired. The VIN was unavailable. The failure mileage was 12.
