I own a 2004 chevy Impala and the ignition fails, then you have to let the car sit at least 10 min. Then it will start. This is a problem from the factory and from what I've read this seems to be a manufacturing defect.

The contact owns a 2004 Chevrolet Impala ss. The contact stated that while putting the car in reverse that the vehicle stalled. She was able to restart the vehicle. The security light illuminated on the instrumental panel on different occasions prior to the failure. The dealer was contacted and informed her that the security system was unable to recognize that the key was in the ignition. The failure mileage was 85,000. The vehicle was not repaired. The VIN was unavailable.

The pass lock system will not allow my wife's car to crank at times. You have to leave the key in the ignition for 10 mins before the car will start. This has happen when my wife and my twin girls were in a bad place and had to lock the doors and just sit in 90 deg weather chevy dealer has no answers. This is a safety problem what has to happen before they are made to fix it someone has to be killed or raped because the car won't crank.

The contact owns a 2004 Chevrolet Impala. The contact stated the key would not turn in the ignition. An independent mechanic was notified and informed the contact this was a known failure with this vehicle. The vehicle was not examined for the cause of failure. The failure and current mileages were 75,000. Sm.

2004 chevy Impala the manufacturer installed passlock system continuously locks the car from being cranked. Everything will operate properly except being able to crank the vehicle. This happens about every 20 times you crank the vehicle. You have to wait at least 10 minutes before the vehicle will crank. If you take the key out of the ignition during that time it is likely that the system will not reset itself, thus starting the process over again. I contacted 2 gm dealerships who said they could not fix it. Had another mechanic look into it and he tried replacing the ignition but that didn't work either. That cost nearly $800. 00. Now I sit in the blazing sun or freezing cold or rain and wait for the car to finally start. Gm needs to fix this for all owners at no charge. Sadly for them, it is not just Impalas that are having this trouble; it is across the entire product line of gm models.

Vehicle speedometer suddenly quits functioning. Speedometer suddenly shows high speed (example 120 mph) when driving highway speeds. Speedometer remains stuck in this position. I was able to clear the error after returning home and cycling the ignition from off to on many many times. Now the tach just !@#$% out and stays at 6:00. I been also having transmission issues to where the tranny would occasionally shift hard then be fine for a while then back to shifting hard?.

Car intermittently fails to start. Power to accessories good, but ignition will not work. After 30 minutes or so, it starts, with no problems for 1 -2 months, then it happens again. I took it to the dealer, who read the code and replaced a part, but after a few moths it started happening again.

2004 chevy Impala has a malfunctioning "passlock" system. The ignition will not allow you to start the car at times - very frustrating. You must wait for it to reset itself, which sometimes takes a half hour, I know many other Impala owners are having the same problem.

While driving to chicago the tachometer went all the way to the red. After pulling over to confirm the car was not running hot, I found that I could reset the gauge by slowly turning the key on and off to the accessory position; until the needle reached its original position. This continued to happen sporadically for a month or so, and then I noticed I was driving on the interstate with the flow of traffic, but the speedometer was only reading 30 miles per hour. I had previously used my cruise control at the set speed, and was able to use the 'resume' button to give me an approximation of how fast I was currently going. This allowed me to get home safely. Again, I was able to reset the speedometer by turning the key in the ignition to the on and off position. The next failure came shortly thereafter, with the gas gauge. Knowing that it was a full tank, it was reading empty; again being reset with the on/off of the key in the ignition. I took the car to the local dealership to get these safety issues taken care of, and was informed this was going to cost me $600 because it was out of warranty. . . It only has 40k miles on the vehicle. I have been trying to resolve this through Chevrolet ever since then, and they agreed to pay 1/2. This only leads me to believe that it is indeed a safety issue that should be covered by the manufacturer. I can't drive a vehicle without a speedometer, tachometer, or gas gauge, and I can only wonder how many other individuals are out there that have been in this same situation.

I have noticed that for the past few weeks, whenever the temperature is below 20 degrees, the speedometer acts funny. The speedometer reads anywhere from 25 to 80 miles faster than my actual speed; today, I wasn't going any more than 30mph at the most, and the speedometer needle was pointing directly down to the car floor. A few people on a couple of message boards suggested turning the ignition key to 'accessories' on and off rapidly several times, but all it did was bring the speedometer down from 85 to 70.

The contact owns a 2004 Chevrolet Impala. The contact was experiencing difficulty turning the key in the ignition. He eventually could not get it to turn at all, which prevented him from starting the vehicle. The vehicle was towed to the contact's residence and will be towed to the dealer soon. The VIN was unknown. The current and failure mileages were 95,000.

The ignition stopped working. The key would not turn. The car only has 19,000 miles. This is going to cost $600 to fix. The car was purchased new in 2004.

2004 Impala, speedometer problem works when it wants to,at times registers 0 and at other times the needle buries itself, would be able to click back to 0 by turning the ignition on and off until it went back to 0 but worked erratically,finally stopped working altogether, temp gauge same way. Only way to fix problem was to have each and every gauge rebuilt and not replaced with gm part as the part they replace it with is the same !@#$% originally installed, researched this on line and found 1000's of others with same problem, this should be recalled, as when the temp gauge buries itself you don't know for sure what is going on, if its for real or ????.

Automobile quit running while on highway and failed to restart. This situation, I feel, put mine and my wife's lives in danger. Research has revealed this situation is common in this type of vehicle. Passive security system overrides operators attempts to start car. Calls to gm and gm representatives produced negative reaction to consumer complaints.

Driving on a trip and all of a sudden my speedometer mph indicator jumper to 90 mph as I was sitting at a stop light. When I proceeded forward the indicator needle reset you 90 mph and this reset continued until it was pointing straight down. It did not reset after turning the ignition off and on. I had no idea how fast my vehicle was going after that. I went to a web site for auto troubles and found 72 reports of the same problem with gm speedometers. I strongly feel that this should have been a recall since a nonfunctional speedometer is a safety hazard. Ps - other gm models also have reports of this malfunctioning speedometers. Gm want $500 to replace the entire speedometer, when a simple capacitor fix is all that is required. A temp fix works for a few weeks, they it happens again and gm said if you replace the speedometer and it happens again, then it costs another $500 to replace the replacement? gm wants to fleece us!.

2004 Chevrolet Impala security light comes on, locks the ignition, and doesn't allow the car to crank at anytime.

Smell gas when not around gas station and ignition problems sometimes I must start the car twice.
