Alternator/generator/regulator problems of the 2004 Chevrolet Impala

The only recall I was able to find out was for the ignition,. My transmission just went out 11/19/2015, it will not switch into gear, it starts just fine no check engine light but left me stranded. Turned the car off and when I started it again it drove just fine, so I slowly drove it home. I don't get on the highway no more because it lacks power the get up is not there mind you yes I have 225k miles on it but I have had about 10 trouble codes and I managed to get rid of them all when I cleaned the tps, aic, and map sensor new egr valve, oil change tune up transmission flush all has been done this year and still on the highway it struggles, I did have one code that popped up 0420 so at this point I have been thinkin to just replace the catalytic converter when I get my taxes, but the problem is just getting worse and worse, so then I am thinking its the fuel pump, I mean my alternator is fine, I know I am sick of the security light always coming on, my left blinker only works in the day time at night never which is the weirdest thing, my windshield blades only work on the fastest setting, in the winter when it rains or snows my doors when we get inside to lock them the lock and unlock and the panel says door ajar when there is no door ajar,it will drive just fine as it nothing was ever wrong. Inconsistent and whats even weird is now the check engine light wont even come on after my transmission failed me in the middle of the road you would think the computer was able to record something. Once tranny fixd I will get the ignition recall fixed originally a loud noise was coming from engine like a screeching noise so I figured it was the alternator now that noise is gone but the minute I felt it wasn't the tranny, my car at the light would not go at all until I turned it off and back on. Please help me.

Head lights will not turn on, blinkers will not turn on, traction control turns itself of and you cannot turn it back on. The following dash lights illuminate. Check engine, battery and abs. This has been happening for about a year on and off. Started at about 80,000 miles. Sometimes only one of the above conditions occur and sometimes all at once. Problems happen day and night, damp or dry, usually only occur during engine start up, but occasionally has occurred while driving. I found a trick to make the head lights come on (turning on and off my hazard lights). My fog lights are not affected by these issues. I have had the battery and alternator tested multiple times because that is the direction everyone points me too. Both are good. I see others having the same issues. I hope this gets look into.

Have had a instrument panel cluster I have dealt with for along time why? the car will not start at times due to the malfunctioning security system, wait ten minutes and hope it starts, come on american made g. M. Stand up to your ownings. Now fuel pressure regulator is leaking, have heard of numerous after market recalls not g. M. Related parts once again own up to your product,especially when it concerns life and death of people especially children, for what money? profit? somebody with some power over these issues do something please.

My wife was driving home from work when the engine stopped running and caused her to have to pull off the road. It took several minutes before car would restart. Since the first time she had this happen at least 3 times a year since. I've driven the car several times after she has told me it happened again and had our mechanic look at it also. Also have had the instrument panel gauges not working properly for 2 years now and haven't been able to figure out why, we think there is a short somewhere in the electrical system but have not been able to pin point it. The chrome plate aluminum alloy rims the chrome has been flaking off since the car was 2 years old and we now have to keep refilling the tires with air at least once a week. Have gone to the dealer a couple of times but get a run around that its not a problem with the car. I have talked to a gentleman who also has the only other 2004 Impala ss in our town and he has the same problems as we have had and gotten same response from our local dealer where we both bought our cars from. My Impala ss at this time has just over 80,000 miles on it and in addition to problems mentioned above we had to have power steering pump, rack in pinion and alternator replaced and looking like the rack in pinion is going out again as I write this. I've become very disappointed with Chevrolet over this car.

The speedometer started getting stuck about six months ago. For about eight months I have noticed that when I turn the steering wheel I hear a noise in the front of the car, like a knock or something. Also within the last couple of months I have also smelled gas when I first start the car , my husband could not see any leakage or anything until last week. It was leaking from the fuel regulator valve. Now the transmission is starting to shift hard sometimes. I haven't had the money to get it all checked out by the manufacturer but I was wondering if there have been any complaints on any of these things. Also I can hear a whistling sound when I press the accelerator. And my husband just informed me that he bought a regulator valve for it and some o rings because something is leaking antifreeze slightly. Can you help please!!!!!!!!.
