2004 Chevrolet Colorado: won't start

Filed Dec 11, 2022 · Electrical, Transmission · KY

Ignition safety module known as pass lock security. This causes my vehicle not to start and give a code and a light on the dash for the Pass Lock security. The vehicle was fine then I went into a store came out and put the key in the ignition, the lights on the dash came on but it would not crank. This is very hazardous cause It could happen while you’re driving anytime, which could cause the vehicle to go into security mode and turn vehicle off making it very dangerous for passengers in vehicle. This is a problem with other Chevy Colorado's when I research this problem.

Vehicles bcm-body control module is defective or the system in its self is defective. Vehicles will not start or may shut off at random from time to time. Scan tools will not be able to recognize the problem as the bcm. So repairs made may make it seem like it fixed the problem but a couple hours/days/weeks later the problem will disguise it self as something else or even come back as the same problem. I myself was told it was the starter and hey it worked, until 3 hours later. Then told the ignition passlock was defective, got it fixed until 1 hour later. Now I have narrowed it down to what controls the whole system, the bcm. Many people have complaints about this same issue all over the web forums, I dont know if any has been reported to the federal safety agency. So I figured I would start. I have this system effects 2004-2012 models of chevy colorado, gmc canyon and hummer h3.

I bought this vehicle in 2014 with only 86000 miles on it. I had to have brand new key cut and programmed when I purchased it. Starting in july of 2016 I started having issues with it not starting and cutting out. Now it won't start at all. It is the theft system not allowing it to start. I have read thousands of complaint about this issue over many different gm vehicles. Some nearly causing wrecks, stranding people with kids , etc. Why has this issue been let go for so long. Does gm not care about their customers. I bought another chevy right after I bought this truck. We got rid of it because it was doing the same thing.

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.

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.

2004 chevrolet colorado. Consumer writes in regards to a defective ignition switch. *smd the consumer stated, he paid to have his ignition switch replaced, and is seeking reimbursement. He stated there were times, when the vehicle would not start, and it would take anywhere from 20-30 minutes. Over several years, he took the vehicle to the dealer, explaining the problems, with trying to start the vehicle. Each time he was told by the service manager, the problem could not be diagnose. Eventually, he took the vehicle to a repair shop, and the problem was finally diagnosed and the ignition switch was replaced. He no longer experienced starting problems. However, in september 2013, he decided to trade the vehicle.

Some times, the car will not start if the ignition key lock light blinks. I have to wait ten minutes so that it starts I have taking it to the dealer and they have said that it has a faulty ignition housing, of course they want to charge me a lot to fix it. I believe is a factory defect. My truck has a salvage title, so the warranty on it was voided. I have heard of other chevy colorado trucks with same problem.

Chevrolet has a known ignition system defect since march 2009. My 2004 chevrolet colorado intermittently does not start and then starts on the second try. Chevrolet's document: "#pip4575b: intermittent click no crank or brief crank no crank with dtcs - possible crank sensor - keywords bqmi - (mar 11, 2009)" explains the defect. I took my colorado in for service on 04-05-12 because it was not starting at all. They advised me the ignition cylinder was "not reading the key" properly. They replaced the ignition cylinder and reprogrammed a new key. This repair did not correct the intermittent no crank problem but did bring the problem back to the state where it would start on the second attempt following a no crank occurrence. I am convinced the initial ignition defect was the eventual cause of the complete failure of the ignition to start the vehicle. I believe this could be a safety issue on the vehicles affected by the intermittent no crank problem. If one of these vehicles stalled out, the possibility the vehicle could fail to start immediately, could cause an accident. Even though chevrolet claimed the problem was under investigation, there has been no notification of any fix for the problem that I know of. I would also note that chevrolet is charging customers for diagnostic testing and ignition cylinder replacement even though they have know of this defect since 2009. However, replacing the ignition cylinder and reprogramming a new key is not correcting the original "no crank" ignition defect.

For the past year my 2004 colorado has intermittently failed to start when ignition key is first turned to start position. By turning the key off and than on again it will start. It does this once in while, but always seems to start the second or third turn of the key to the start position. Twice over the last two years it wouldn't start at all and I had to let it sit for ten minutes or so, than try again, at which time it started. I believe the problem is caused by the pass lock security system. Because its out of warranty I haven't done anything about it.

Vehicle sometimes will not start. Once it happens, let sit for 10 minutes and it will then start. Taken to dealer and was told it is the passlock (security) system. Checked internet, seems to be a common problem with newer gm vehicles.
