Grand Prix GT 3.2L V6

  • Automatic transmission
  • 150,000 miles


05- Pontiac Grand Prix- "The car is kept in pristine condition; including the interior and exterior. Electrical Issues * The car is known to have good, bad, and ugly issues. The.. "ELECTRICAL" issues can be the most frustrating and difficult to trace where the repair is either pennies or astronomical. The issues most noticeable are; fading of dash board lights, blower motor and blower motor controls. The issues are all 'electrically ' oriented and can be fixed and prevented ! The fix is quite simple. The 'battery' is the key to a major portion of the problems.

First, make sure your battery is up to original or near new standards. Meaning, any auto parts store can tell you in a heartbeat if the battery is good. It's a free check and only takes a few minutes. Be sure to give the employee a tip for their 'free' service. Second, the battery is fine so what to do now?

Pontiac or GM as they are sometimes called; used the cheapest piece of junk they could find in this one area; the item is known as the 'battery terminals." This is the point where you'll see where the wires are attached to the car battery. It's time to say good-bye to these idiot designed pieces of metal.

Third, ask any auto parts store for a set of 'new' battery terminals. If you can't figure out how to install them, ask a friend or Electrician or mechanic for a bit of help.

Fourth, having replaced the battery terminals; and a bit of battery cable wire; start the car. Amazed? The lights will be brighter, the car will instantly run smoother and your Electrical Issues are mostly solved. And.. the few dollar fix .. just saved you some very irritating and expensive repairs down the road.

If you choose not to replace the battery terminals .. buy stock in the company who supplies the electrical replacement parts you're buying.. Hope this helped and pass this along to anyone who owns one of these beasts..or.. don't .. and tell it to the pet parrot.. it'll impress the crap out of company when the bird starts talking about Pontiac's.

Grand Prix GT 3.8L

  • Automatic transmission
  • 72,000 miles

Lights on the dash are flashing different prompts, ABS light, Traction control, Low Fuel. The gauges are dropping to zero while I drive and also the other day my car wouldn't start. I had to shift it in gear in order to start it.

Grand Prix GTP

  • Automatic transmission
  • 158,432 miles

Went into store, all was fine. Came out, started car, all kinds of warnings lit up on the information screen. Check ABS, traction control system, brake system, assisted steering control system, stabilizer control system. I have noticed steering feels a slight bit harder/stiffer, but nothing else. Given the possible failures, (going on my head) I'm afraid to drive too far. Any suggestions?

Grand Prix GXT 3.8L

  • 165,000 miles


I had only owned this vehicle for about three months before I began having this problem. I took the vehicle to get an oil change and they gave me a free estimate of the repairs for my vehicle which upset me to no end because I bought this car which was sold to me as a 2006 & in fact it is a 2005 and then all of these lights start popping on (check engine, traction control, etc). I want GM to fix all of these issues at no cost to me.

Grand Prix 3.6L V6

  • Automatic transmission
  • 169,000 miles

I keep getting an error saying Electronic Throttle Control Disabled & Reduced Engine Power, and several times I've had my car stall on me in the middle of the highway causing me to have to pull over in a dangerous position. After letting it sit for a few minutes and putting it into park and turning off the ignition, I was able to start it back up and the error dissapeared from the dash display. When I've taken it in every time after this problem has occured they give me no answers saying my car is perfectly fine. This does not seem fine to me when I'm stalling in traffic!!! And recently within the last year, especially in the winter, when it gets below 20degrees outside it is giving me the same errors, so I figured maybe it is because I need a new battery; well nope that sure wasn't the case, after changing the battery the problem only seemed to get worse. Then it started dying in traffic again, and it would end up being a 15 min wait until I could start it up again. I know something is wrong, but no one can give me answers! So irritating and when I try to contact GM about it they basically talk to me as if I'm dilusional, worst part is I can't afford to get a new car, but I'm just so fed up! Does anyone have any answers?

Grand Prix GT V6

  • Automatic transmission
  • 89,477 miles

Gauges drop to zero, warning light: ABS, traction control, fan shut off while driving. Pull over, shut off car, unlock doors, open doors, then restart car. Everything is working great. BUT it happens several times a week! Took it to Petersen Pontiac for a Diag test read;scan code U1016 loss of comms with PCM, history in DIC.HVAC, SIR, BCM, & IPC. U1064 Loss of comms with BCXM in VCIM. U1000 class 2 data link comms error on SIR Module. All code are history only. This test cost me $161.99. Advised to replace ignition switch so I replaced battery, ignition switch & alternator.Did NOT solve the problem. I do NOT turn on my stereo. Only use the fan when needed. I have to HIT the dash board to get the fan working. IF I do this, it does not happen as often. Solution; SELL or REPAIR? My 1st choice is to get this fixed. If the dealership does not know how to fix this, who does? Sell it & give the problem to another? HELP!
