  • I went to Chevrolet.com and built an SS w/ convenice group and waddya know, heated seats and mirros on the "View Window Sticker" on 3 Impala SS's at a dealer in Pittsburgh. Fantastic! I think I found my next car . . .

    Congrats! I know how much I love my LTZ, so I'm sure you'll love the SS even more! Let us know what you end up taking home. :)

    Ivanadrivealot, thanks for the reply. I only wish I knew about this blog before I bought my car. I wouldn't have accepted it knowing this was a common problem. I was actually hoping mine was an isolated incident. Oh well...serves me right for assuming a Bose system would be quality controlled. I will seek a fix and will pass it along if I find it.

    The noise referred to in the TSB is different than what we've been working on. The engine tick will be heard at a regular rhythm on a cold engine; that's my understanding. The noise from the I/P will be heard when the car is warming up from cold temperatures, does not have a regular rhythm and will be heard across the top part of the IP. We believe the noise is coming from metal clips on the underside of the defroster grille panel. These metal clips hold the defroster grille panel into the IP top pad. Our current repair is to remove the defroster grille, (which requires the windshield garnish mouldings to be removed first), remove the metal clips and put an anit-itch material onto the clip towers. This seems to provide enough isolation to eliminate the clicking noises.
    To the owner who didn't want to trial the fix on their car; yes, I can understand your position. Don't mess with my car until you know what you're doing. At the same time, I appreciate those of you who contacted me and allowed this fix to be trialed. I know the people on this forum will not tell me a problem is fixed until it is.
    As for those who are concerned if it will cause a problem later on if not fixed, my opinion is that it will not cause any further problems. In time, it may go away on its own as the vehicle ages and parts shift due to their own aging.
    And by the way, thanks to all those who have purchased Impalas. There are many people here in Oshawa who would like to thank you.

    Its good to know that there are people who are looking into these problems with the 2006 Impala re clicking noises/ seat heater problems. The only way to get any response is to let your dealership service manager know that you are having these problems. Does anyone know if the Impalas that are rolling down the assembly line right now today, have they had these issues corrected at the factory? The 00-03 Impalas had there share of problems, and some were a long time in coming before proper fixes was made.

    it's not the charging citcuit or the battery that's the problem: there's a drain on the battery when the ignition is switched off: start pulling fuses at the fuse panel to isolate which circuit is the culprit. this is just the first step, but at least this way, you will know what fuse to pop at night so your battery won't drain. obviously, this is not the solution; the dealer will have to trouble shoot the problem to isolate the culprit.

    The overnight battery drain has only happened once. All other times the car starts strong with not even the slightest hint of a weak battery. I'm holding off taking it to the dealer unless it happens again.

    Thanks for the reply.
  • Thanks for the info Ray. I rented the GXP at Avis, got it as a free upgrade and it was pretty nice. Had been thinking about the SS and had forgotten the GXP had the DoD 5.3 as well. I like the styling slightly better on the pontiac. I am going to the auto show this weekend to look at them all in one place and see what happens. Have a gm card and they have top off rebates for the next month so will see. I am trying not to obsess about MPG, but the figures looked almost too good to be true, particularly some of the guys I am looking at have turbo fours and get much lower mileage. Do you always run premium? Is it required or recommend?

    Thanks,

    From the owner's manual:

    "If your vehicle has the 3800 Supercharged V6 engine
    (VIN Code 4) or the 5.3L V8 engine (VIN Code C), use
    premium unleaded gasoline with a posted octane
    rating of 91 or higher. You may also use regular
    unleaded gasoline rated at 87 octane or higher, but
    your vehicle’s acceleration may be slightly reduced, and
    you may notice a slight audible knocking noise,
    commonly referred to as spark knock. If the octane is
    less than 87, you may notice a heavy knocking
    noise when you drive. If this occurs, use a gasoline
    rated at 87 octane or higher as soon as possible.
    Otherwise, you might damage your engine. If you are
    using gasoline rated at 87 octane or higher and you hear
    heavy knocking, your engine needs service."

    As there have been many posts elsewhere on Edmunds about the use of Regular or Mid-Grade vs. Premium in many cars designed for Premium, I will only add that given the GXP is a high performance car (low 14-s in the Quarter Mile qualifies in my book) and that I bought it specifically expecting to enjoy that acceleration performance whenever I want to or need to – I run Premium. And since I cannot reliably predict when I will want or need all the HP & TQ available, I run it all the time.

    There are lots of alternatives to the GXP with motors that are designed run on Regular. (Are there any with V8s making over 300 HP / TQ and such a sweet sound?) At 20 cents per gallon premium for Premium (I crack myself up) and an average fill of 15 gallons or so (for me) the additional $3.00 – out of over $40.00 / refill total these days – is worth it to me.

  • First, I was under the impression that the Grand Prix and the Impala would have the same size back seat. They don't !!! The Grand Prix's back seat (according to the measurements) is much smaller. This was important to me since I need to get 3 car seats in the back of my car.

    Second, there was some talk a while ago about the top speed of the Impalas. I haven't taking my SS past 90, but I did just notice that the car comes with W rated tires, which are rated up to around 149 mph....

    Since CAR AND DRIVER stated that the GXP had a top speed of 142, I'm again guessing that the SS will also be in the 140's.... Although I think the Speedometer only goes up to 140....

    I also run 93 octane in my SS, it's worth the extra $3.00 per fill up and I've noticed a 1 to 3 mpg increase over the 87 I used for the first 3 weeks.

    Just some random thoughts! :)

    "W rated tires, which are rated up to around 149 mph.... "

    W = rated to 168 mph.

    Not ready to attempt that speed anywhere near where I live . . .

    The overpriced Bose Amplifier/Speaker system may not be the culprit of this problem. It is likely the cheap head unit (Made in China?) that spoils your experience.

    GM just announced that they will move their Electronics
    Purchasing Department to China to save money (they want to be the next Walmart). So cross your fingures.

  • There is a dealer note out that say's the heated seat problem is a software glitch that they (GM) are working on! They do not want dealers to do anything to help you out. I had them change my hardware anyway, and that did not work entirely. This problem is like the mileage and fit / finish issues - just a case of over marketing and releasing a design too quickly. Maybe the seats will work by summer! My best advice is to keep on them to do a recall and replace the seats completely. The 2006 Impala is the worst sales, marketing and production fiasco I have ever seen. Every issue I have had has not been resolved and / or put off because of the lack of available replacement parts. Some replacement parts even came in bad twice. The only things that have not been disrupted with this purchase is my regular hours spent at the dealership, on the phone (both 800#'s and corporate), and my payments for something that is not what I was sold! If anyone want's to contact GM corporate you need to know someone on the inside - the owners 800 line people are really clueless. Is it any wonder that GM stock and business is falling? Maybe they can sell some cars to China where they are taking the manufacturing.

    What are owners of the '06 LTZ 3.9 getting for mpg ?
    Just took delivery and now have 400 miles.
  • zjimzjim Posts: 51
    I have a 3LT with the 3.9 engine that has approximately 1400 miles on it. So far, I have been doing only "suburban" driving on relatively busy streets and low speed highways while on my way to and from work. I've been getting anywhere between 17.5 and 18.5 MPG, depending on ambient temperature and how aggressively I drive the car. That is a little disappointing, since my 2001 Regal, with 57K consistently gets 19-20 under the same circumstances. I have to admit that the acceleration is better with my Impala, but, . . with all the technology improvements made in the last five years, I should be getting at least the same efficiency with the Impala. I'm really looking forward to doing a couple of trips to see if the Chevy can match the 29 MPG that I get with the Buick.
  • jntjnt Posts: 316
    The Regal with 3800 V6 has a lot less Horse Power (40 HP less). Besides, the new 06 Impala is probably heavier since it has more safety hardwares. HP and mass negate any gain on new technology. If Chevy offers 6 speed AT then may be they can offset the loss in MPG (10% better typically). DoD (Displacement on Demand or Cylinder Cutoff) may save another 10%.

    In addition, the 3800 engine is legendary for HWY mileage (30 MPG on large vehicles) since it has benefited greatly from decades of continuous improvement.It may take GM some more years to do the same thing on the 3.9 V6.

    I have about 4200km (about 2600 miles) on my '06 LTZ. Best tank has been 10.61 l/100km (22.16 USmpg). Worst has been 13.55 l/100km (17.35 USmpg). Average is 12.17 l/100km (19.29 USmpg).

    Mileage has been getting better as the engine gets broken in. All of my driving is mixed city/highway, with average speed per tank of around 55kmh.

    I am definitely a heavy-footed driver, particularly with the great acceleration of the 3.9 in the LTZ. It's so much fun to put it to the floor and take off. It will be interesting to see what the mileage is like when I do a cruise-controlled trip down the 401. So far any trips on the 401 have been fun dashes into Toronto with lots of to-the-floor acceleration.

    Being the "gear head" that I am, I'm well aware of the "advertised" horsepower of the Chevy when comparing to the Regal. The Regal I have is a fully optioned car and weight is nearly the same, but the aerodynamics are not as good as the Chevy. With the experience GM obtained from what was considered one of the finest six cylinder engines ever built, that you would expect the 3.9 to perform at least as well. If you drive both cars similarly, over the same exact course, you'd expect the Chevy to deliver similar mileage. For example, the 99 Z28, 6-speed that I traded for the Impala produced almost 300 horsepower at the rear wheels, weighs only about 150 less than the Impala and got the same mileage (or better) over the same course, same driving conditions.

    There's no doubt that a 6-speed automatic and DOD (DOD is rumored to be installed as standard equipment on the '07's) would significantly improve mileage. Imagine how much better the 3800 Buick would be with those same improvements! Don't get me wrong. My Impala is a decent car and I knew going into the deal that it wouldn't get the mileage that my Buick does. My point is that with all the performance and mileage that some GM cars develop, you'd think the 3.9 would be more efficient, just on the motor alone.

    SS showing off on I75 today. Changing lanes to pass people and I heard this loud muffler sound like something from the early 70s on a big motor and it was an SS-black passing at 80 or above. He had a cops emblem on his license plate so he can speed and nto worry.
  • You're right, my mistake. When I was posting I couldn't remember if it was in the high 140's or 160's so I went with the smaller speed.

    You're also right in saying that it is difficult to test top speed. There's nowhere around my area where I can (or desire to) safely go over 140 mph....
