Kind of a weird entry but I have to ask. I am currently building a custom truck and was considering graphing in a G6 Pano roof. I have already sourced a used roof assembly and everything.

This is really scary; how many people hate their pano roof. I was really looking forward to adding this to my vehicle. My question is this. Are most of the problems that people have had with the sun roof on 05 and 06 model years? Or has any one had issues with the later model pano roofs? I can understand problems with them the first year or so, but I was hoping that there have been improvements in the design since its inception?

Thanks for any feedback.

NO! NO! NO! DON'T even THINK about putting one of those awful glass slat sunroofs in ANYTHING!!! This is the WORST design of any automotive accessory in the history of the car (well, with the possible exception of the Pontiac Aztek)!! I don't know a single G-6 owner who has one of these things that has not had rattles and leaks.

I'm a mechanic and I test drove a couple of G-6's when they came out. One look at that leak-waiting-to-happen sunroof was enough to convince me I DID NOT want one. There is simply no way they are NOT going to leak or rattle. They are not insulated or sealed in ANY WAY between the slats. If I bought a G-6 (which I didn't) I would definitely have an aftermarket sunroof put in it, and that's what I'd advise you to do. Otherwise you will be ruining a nice truck.

GM builds some of the best vehicles on the planet (I currently own 2) and I'm not bashing GM by any means. I just think they must have hired Toyota or Nissan to design that AWFUL sunroof!!

I bought a 06 G6 about 4 months ago; nothing but problems, some squeaky noise coming from the back tires that no one seems to be able to fix, sounds like a ref blowin half a whistle, the sunroof leaks onto the middle console through the sunroof buttons, and my brake lights stay on while I'm in motion!

Never will I purchase another Pontiac in my life, I just started med school, the last thing I need is to take time out of my schedule for monthly service visits. POOR CHOICE!

I too have had same problem with my 05 G6. Had the car 2 months and had to replace ball joints (control arm). GM paid for parts, but not the labor, so I got stuck paying that.

Now I am having problems with battery dying as well. Granted, I did buy a first year model, but something basic like battery issues should NOT be a problem. Why hasn't GM fixed this problem is what I want to know. My dealer acts as if I'm crazy.

I currently own a 2007 G6 with the panoramic sunroof and it is awful. I have had problems with it since I bought it a year ago and since then it has been in the repair shop 6 times. It leaks water, the wind noise is unbearable, it doesn't close all the way at times, and it has a constant popping sound. I am currently trying to get GM to buy my vehicle back and so far I'm not having much luck. So to answer the question above, yes the panoramic sunroof is still a BIG PROBLEM.

2006 Pontiac G6 GT Coupe.

Cute car, fun burnt orange color. Wish I never bought it. Of course it is now past its warranty and its in the shop. Has anyone else had problems with Sunroof tube drains?!?! These have become detached and the carpet in my rear floor is soaked, I could watch the rain trickle down my interior. Last week it had to "relearn" the steering positions. Before that it needed the rotors turned. It also needs about $500 in steering work done.

I own a 2005 G6 GT, and the 2 problems I've had with the car don't even revolve around the sunroof. Those problems were the tire bulging (due to accidentally hitting a large pothole) and the plastic front air dam popping off. The panoramic sunroof doesn't leak or anything, with 86000 km.

What may be a solution to the problem is to close the sunshade whenever you don't use it. It prevents water from leaking into the car. I learned that lesson the hard way when water leaked into my 1998 Grand Am GT. But these cars are awesome, everyone I know with one is thrilled with it. My 1998 Grand Am GT was also a good car, despite the few problems I had with it, I just needed something bigger.

2005 Pontiac G6 GT, 3.5 V6. 110,000 miles so far. Original battery is still in the car. Replaced the brakes at 75,000. The car averages 29-30 miles per gallon on the highway. Best highway mileage has been 31.2 mpg. Not bad for a V6 with a four speed automatic. Only unusual repair has been replacing a broken front seat frame ($600). I slipped and fell into the front bucket at an icy parking lot. I've since gone on a diet and lost a few pounds... but I didn't think I was that heavy to begin with (205 lb).

All things considered, this has been a reliable, solid car. As reliable as my last Nissan, more reliable than my previous two VW's. GM should have gotten more credit for this car. It's true it's old tech, but 30 on the highway with a 175 horsepower V6. So what if it has a 4 speed?

I have 2005 Pontiac G6 GT with about 44.000 miles on it. I bought it in November 2007.

Until this morning, I've never ever had any type of issues with it: no sunroof leaking issues, no suspension issues, no brake pads replacement yet (although they are squeaking now), no electric issues, and no battery issues... until this morning.

I turned my car on from the remote starter from inside the house, and when I got close to my car, it was making this awful noise over and over trying to turn on. I jumped in and put the key in the ignition, the car stopped, but the CD player kept doing this weird noise.

I tried turning the ignition on but the car wouldn't start, at all, however, all the electrics looked right, there was some battery power left since the inside lights and the front lights were on. My iPod was on as well, I leave it in the car and I've done this for almost a year now, and I don't think that my iPod sucked the power out of the battery.

I tried turning the ignition on a couple more times but my car never turned on.

Totally unexpected but my battery died.


Update 9/30/09

I purchased a new battery, replaced the original one and my car is running fine now. I did a test drive around the block, used the remote starter, and everything worked fine.

I hope the battery issue gets resolved with this new one now.

All in all, the Pontiac G6 GT is a VERY nice car, very powerful and stylish... but I pray I never have battery problems in the highway in the middle of winter.
