Same here. My temp gauge spiked and the alarm sounded about 30 seconds after starting the car the second day I had it. It stopped after about 5 seconds and didn't happen again until yesterday.

Mine has a nifty set of problems. Mainly, both radiator fans will blow all day long - I have to pop both fuses to prevent the battery from draining.

Also, blinking either left or right causes the fuse to pop. It's about 10 degrees here in New York, but sunny so I figured I'd drive her for a few days... Guess the Aussie build wasn't intended to handle such cold?

Dealership trip tomorrow AM...
:willy:

This may not be your problem, but the turn signal fuse is also back up light, and there's a switch at the shifter that shorted out that caused my problem and fuse to blow when turn operated or put in reverse.

the fans...... that's a new one.

 

[mGTO04]

fans, never thought of that. That may explain my recent dead battery. I have not driven it much due to lots of snow but it should be holding a charge...

 

[TexasRealtor]

Any word if these electrical gremlins have been corrected in the '05?

 

[GTO4ART]

My Gauges went crazy...but it's fixed now...

I had a similar problem with my speedo, tach, fuel and temp gauges giving false reading and full sweeps of the speedo and tach on my 2004 GTO. I took my car to the dealer who, in turn, said it was a loose conection at the back of the instrument cluster. Needless to say, I didn't believe them, but I let them do the work anyways. A week later I had the same problem. This time they replaced the complete cluster and since then I have not encountered the problem. My suggestion is that you have the dealer replace your cluster if you are still encountering the same problem.
Feel free to email me if you have any questions.

electrical problems

I too have had this problem with in the first minutes of start up. It happened only one time. I guess it's time to take it back for service again! Don't get me wrong I love this car, but I've had problems w/ the driver's seat and the deck lid. Every so often the seat feels like its missing a tooth in the gear and the deck lid wouldn't latch. they replaced the latch and actuator in the trunk. I had the car back for one week and noticed I have to pull on the lid to open it. Still not a reason for trade in.

I just got this info from my dealer's service manager.

Speedometer Erratic movement, Fuel Gauge does not go to to full after filling, engine coolant temperature gauge reads hot and coolant temperature light illuminates(REPROGRAM IPC )
#5-08-49-003- JAN 20, 2005
2004 GTO
Built prior to VIN BREAKPOINT 4L29601

These conditions may be intermittent.

Technicians are to reprogram the IPC with an updated software calibration. This new service calibration was released with TIS satellite data update version 1.0 available January 10, 2005. As always, make sure your Tech2 is updated with the lates software version.

Also have you looked at the NADA VALUE OF A USED 2004? Not to bad.

Did your "MPH" indicator dim a little after this update ?

GTO Service Bulletin for dancing gauges

For those with dancing IP gauges, ask you dealer to look into this TSB:

#05-08-49-003 Speedometer Erratic Movement, Fuel Gauge Does Not Go to Full After Filling, Engine Coolant Temperature Gauge Reads Hot and Coolant Temperature Light Illuminates (Reprogram IPC) - (Jan 20, 2005)

 

[Glenn]

TSB for "MPH" label too bright.

Did your "MPH" indicator dim a little after this update ?

Westell,
This TSB was probably also applied when they fixed your dancing gauges problem programming:
#04-08-49-023 Speedometer MPH Indicator Too Bright (Reduce MPH Indicator Brightness Using Tech 2) - (Sep 10, 2004)

electrical problem

I havent had any problems with my spedo on my 05, i did however have a problem with the radio. I was driving one night and all the button lights shut off. I hit a bump, and they went back on. I love the car more than anything, but thats a little stupid for a brand new 30+ thousand dollar car. Mine is going back to the dealer for that, the caliper was scratched from the factory, and they told me they have to evaluate it first. What a crock of Sh*t. Also, the hood scoop wasnt finished being painted, and the wont paint it for me....or swamp me another one. It seems to me they just dont wanna help at all. Shes my baby and i guess we will have to deal with it.

You're right it is a crock of s**t. You have a legitimate claim on the caliper and hood scoop paint. I would call the Pontiac Customer Assistance Center number (800-762-2737) and state your case to Pontiac. Many dealers don't seem to care about customer satisfaction unless it benefits their profit; not GM's future sales. Pontiac should be more helpful

I test drove a 05 the other day, interesting experience. Neither the gas gauge nor the stereo worked! The gas gauge needle was sitting on empty, and the digital readout continued to blink/flash warnings of low fuel. This after the dealer dropped a few bucks in the tank. The stereo sounded like the rear deck speakers were blown… horrible popping and cracking sound.

Ring up a dead cluster for me.

Speedometer was doing the 200 MPH swing back and forth a couple of times. Thought it may just be a simple program fix. Took it to the dealer and the cluster died on them.

Been a week and parts on backorder. This is real dissapointing as the car hasn't had any problems until this. Now, there are no parts and no ETA. According to my dealer, there is only one shop in the US that makes the cluster and/or parts.
This sounds like this could be a while. If it goes more than a couple of weeks, there will be a personal call to GM.

Granted, they have given me a rental car. First a full size truck. Couldn't afford to put gas in that guzzler and gave it back for a Grand Prix. But the rental sure isn't like driving a GTO and that is what I pay that payment for each month.

 

[SFLGOAT]

Took my goat in for the same thing last Monday and a few other minor issues. I know it will be a while, but is is disappointing to hear your story. I am really starting to miss my goat. (The Grand Am rental is just no cutting it). I will be out of town from the 17-21. I will be getting real edgy if it is not back by the time I get back. Please post any info you receive and I will as well. :cheers

 

[jdc916]

Ok ! I've read all the pages of this post (whew) and by the looks of it, all the electrical gremlins appear to be with the 04, based on what everyone has listed in the "My GTO" section. I think maybe there was one 05. Is it a safe bet that the problem has been fixed for the 05's ?

 

[1HTVIXEN]

Here is my problem, the battery in my 2004 GTO, has died several times in one week.
1st time, I thought I left something on, nope. I had it towed to the GM Dealership, where I work. They replaced the battery on Monday. Friday morning when I went to leave for work, as I unlocked the car the horn beeped repeatedly. When I went to start my GTO, its was dead and I mean dead. So I had it towed back to my dealership, where it was tested and had less than 6 volts. I got it back on Friday afternoon and then again on Sunday, the battery was dead again.
The techs and myself are all confused since there is a draw somewhere, but where is the question. The car is locked, everything off and the battery dies....
I have also had problems with the cluster, but my tech explained to me that
there is a service bulliten to fix that problem.
My tech has told me that my car is an ideal canidate for a buy back or lemon, since they have tried to fix the problem three times.
Has anyone has a similar problem?

 

[mGTO04]

I am not sure I may have already responded on this, but obviously this is a major issue with the batt that they come standardly equipped with. I am from Iowa, and mine sits for good lengths of time due to snow...however the battery has died several times and finally they ran diagnostics on it and need to replace it. The interesting thing about that is the battery is on back order until July. They put a temp in, but it is a huge problem or why would they be out of stock? I had the same speedo issue on one occasion after refueling. Turning the car off, and restarting solved the problem. My dad owns the dealership, so I would say I am getting the straight line on the battery issue...but who knows. Otherwise, great car and I just ordered the 05 replace hood to add on.

Hello, All;

I just found this forum; I am in the delicate process of negotiating purchase of a new 2005 with the wife, and am doing a lot of online research. This thread caught my eye, and I read it from beginning to end. Maybe I have something useful to add to it.

Years ago, when I was working as a dealership Porsche tech in northern California, a customer brought in a 928 that had received three replacement instrument cluster circuit boards. Each of the flexible boards had burned traces, and the persistent symtoms were intermittent wild fluctuations and full scale movement of the analog instrumentation - fuel, temp, oil pressure - which would often subside when the car was turned off & restarted. Clearly this was not a problem with the circuit boards, and I knew that the burned traces were the clue to the root cause. I suspected that a ground problem was causing the alternator current to return through the cluster via the engine's instrument senders, so I began to check for voltage drops in the body ground path while the engine was running & the headlights were on. Sure enough, there was a potential difference of several volts between the body and the engine, so I raised the car up on the lift & attempted to remove the nut for the engine ground strap - the nut & stud came off in my hand. An insert and new stud were all that were required to restore proper electrical function to that Porsche, which had less than 10K miles on the odometer. I would suggest measuring for voltage drops in the chassis ground path of the affected cars. Begin at the alternator, engine running, with a load Could be something as simple as paint on the contact area under a ground strap.

My GTO just hit the motherload of electrical issues. THe whole instrument cluster goes dead, radio quits working, daytime driving lights shut off, display reads check alternator, abs malfunction, etc. It seems that if I let it idle it will go back to normal operation but if it gets above 1000 rpm all heck breaks loose.

Anyone know where that bad ground for the computor is? All Data doesn't show it.

 

[GTODEALER]

One of my customers in OH just had this problem!! He took it to his dealer and they replaced the battery and the alternator and the problem went away!! Hope this helps... BTW the alternator takes a while to get so get to your dealer asap!! :cheers
