2006 Chevrolet Impala

    This is clearly a generalization:
    many problems that plagued the 00-05 models. cracked, body mounts, intake manifold leaks, warped rotors, Intermediate steering shaft problems, cheap interiors, etc etc
    inasmuch as my 03 Imp hasn't had any of these problems (I don't consider the interior a problem as it is well assembled, doesn't rattle, and doesn't distract me while I'm driving.)
    The early model years probably had most of these problems but not likely in 03-05. Likewise I would wait at least a year to buy a new Imp.
  • Probably good advice for any automaker, not just GM. Granted I might not sweat a 1st year Honda or Toyota as much, but even they have their problems (my wife's 2003 Accord has brake clunking to rival my 2000 Impala ISS noise, but all we're told is "they all do that" least Chevy fixed my ISS!!).
  • Granted the Impala has many new features and a new interior and engines but is it really "all new"? I'm ordering one in February and I haven't heard many complaints about first year problems. My next choice was a new Malibu but the price differential between a Malibu LT and an Impala LT2 is very little and the interior in the Impala is far more attractive.
  • New engines, new interior, new exterior...that doesn't leave much to carryover from the previous model! :-)

    One of the reasons I bought they 2000 Impala was for the "bullet-proof" 3800 engine...which due to the plastic intake manifold ended up being one of the biggest problems encountered with the car. I don't know much about the current line of engines available, but if they've been used in other GM products I'd suggest checking those threads to see if any consistent problems have arisen.

    Despite that I'm very happy with my 2000 Impala, and I'd have no qualms in a couple of years when I'm ready to replace it with buying one of the new versions. It was the best combination of size, power, fuel economy, safety and value 6 years ago, and it's looking that way again!

    We're approaching 3K miles on our '06 LTZ (3.9), and getting fairly good gas mileage. A few days ago, I gassed up and hit the Interstate with light traffic conditions. People were running about 80, so I just stayed up with them. We pulled off after about 150 miles, and I gassed up again. Average speed for this run was 78.6 MPH, and I got 26.2 MPG. A couple of weeks ago, we ran a couple of hundred miles on state highways at 55 to 60, and I averaged 28.1 MPG. We don't have these "designer" fuels here, and I have been using the midrange 89 Octane fuel. This is one of the best cars I have owned in the past several years. After 3 months, I have found zero problems.
  • Two things that I recall being stressed when the 2000 Impala came out were 1) how the car was designed with police/taxi service in mind, and 2) how the structural piece around the door openings was comprised of ONE piece (no welds or seams anywhere within the openings which would weaken in a crash).

    I admittedly haven't followed the introduction of the 2006 Impala as closely, but does anyone know if either/both of these details of the 2000-2005 model are applicable to the new version? Even if not promoted as such, it would be nice to know if the same (or better) level of structural integrity was built into the new car.

    A lot more steel support brackets have been used in strengthening the chassis of the new Impala. Larger steel support rails in the engine compartment and engine and transmission supports strengthened. Chevy now using quiet steel for many components (like Ford trucks) to cut down on interior noise. I believe they are using much stronger steel supports that are boxed railed rather then weak open ended supports from previous. If you look at the wheel wells of the 06 Impalas they are enclosed much better then the 00-05 models. The side window glass is thicker to enhance quietness to the interior. The DIC now has an option that gives pressures for each tire, rather then previous just letting you know that one of your tires is down 20% or more. Better quality interior plastics and cloth and leather appointments. A lot of improvements that you can see and a lot you can't. With many of these improvements the car is more then 120 pounds heavier then previous Impalas.

    I thought the 3800 had the intake design fixed in 1999. The 2000s didn't have the breakdown of EGR tube and leaks from throttle body into or out of the manifold. What kind of problem did you have?

    This message has been approved.

  • I too had the 3800 engine -on '90, 94, AND 97 LeSabres -always trouble free. The 2000 Impala was a great car -glad you are happy with it. I'll take my chances with the new one -luckily I'm not commuting anymore so it will not be run to the ground. I expect to have it at least 5 years.
  • Those of you who might be considering Glacier Blue should actually look at the real car, not the photo in the catalog. The catalog photo looks like silver with a blue tint but it is a lot bluer in real life. The Silverstone I think looks nicer. It is sort of like the Cadillac Cashmere but with a silver instead of tan tint -I saw both colors side by side and was suprised at the Glacier Blue. I've switched to Silverstone.

    It's all in the eye of the beholder. We've got a Glacier Blue LTZ, and it changes colors depending upon the lighting. In bright sunlight, it shows more of a bluish hue, but on cloudy days, or under lights, it is more of a silver/grey. One thing I am glad of is it doesn't show dust or road film too much. We live out in the country, on a gravel road, so darker colors get to looking bad real fast. This GB looks pretty good even when quite dusty.
  • There was ultimately a recall on many of the early Impalas because of a coolant leak related to the upped intake manifold (if memory serves correctly). I noticed the smell of warm coolant and had the repair done (at @ $800), and then later a recall was issued and I got reimbursed for the repair. My understanding is the intake used to be metal, but somewhere along the line they switched to a plastic/synthetic part, which tended to warp or something, which led to the leak.
  • Another feature which was a big topic of discussion on the 2000-2005 Impala board back in the day was the aluminum engine cradle; does anyone know if the 2006 model retains this, or did they go back to a more traditional setup? I've had no problems with mine, so it wouldn't really impact my decision one way or the other, just curious to see if they stuck with this or not.

    I had the intake manifold leak (luckily) outside the engine in my Bonneville '02, with about 20000mls. It was replaced under warranty and then I took it back again for a recall to replace the manifold nuts, IIRC.

    That advice has some merit...on any new model, from any car company. However, there are 2 schools of thought on that subject.
    1. They build a car that tests good, and looks good on paper, then spend the next 5 years trying to work out the bugs.
    2. They build a quality car with very few troubles the first year, then spend the next 5 years trying to build it cheaper, and start cutting corners on quality.
    Personally, I have had better luck buying cars that are newly designed. The manufacturer is taking a gamble that the new styling, etc., will capture more sales. They have to go to extra measures to make sure that the new model does not get an early reputation as being a lemon. So far, our '06 LTZ is following that pattern...over 3 months, and ZERO defects. I ran into a guy at the casino parking garage a few days ago with an '06 LT, and he said the same thing about problems.

    What year Impala needed this manifold repair? What engine does it have?
  • I've had my 06' SS for a little over a month now with about 900 miles. I've not only had ZERO defects, but I am still amazed at how quiet this car is, there aren't any rattles, squeaks, or vibrations to speak of! :shades:

    BTW - the Laser Blue is a nice color too!

    The intake manifold problem involved the 2000 and 2001 Impala 3800 engine cars and other GM cars... there was a recall on these and at the time mine went in for the retrofit. Which included more secure bolts for the intake and ground up walnut shells for the radiator to keep the coolant from leaking. I know over the past few years many had this problem and were outside of warranty and the costs run near $700- $800. I would be very careful buying a used 2000 and 2001 Impalas...there was a host of problems with these cars and not all went in for repairs. Intake manifold leaks, engine cradle, Itermediate steering shafts, and poorly designed brake rotors to name a few.
    The 2000 and 2001 Impalas made the first 9 months of 2001 had the problem with the aluminum engine cradle. The welds would crack and the car would creak. It was a big problem and several posters here back then had the issue. Several fixes were tried including using shims and rewelding, but finally better aluminum welding and much better joint aluminum materials were used to strengthen the cradle. According the Chevrolet the 2006 Impalas use a much stronger different design engine cradle then the previous 00-05 models.

    When I changed the oil/filter at 1000 miles on our '06, I was a little surprised to see that aluminum sub frame from the firewall forward. I spent some time under the car, checking that out. That's quite a piece of "bridgework" they've welded in. I guess the main reasoning is to have a better crush zone in the event of a frontal crash. It certainly looks strong enough to me. It looks like the factory did a good job on assembly in this area.
  • Just received a letter from Chevy today:

    It's not a "recall" per se, but is being called a "voluntary customer satisfaction program" that affects certain 2006 Impalas equipped with ABS and 17" or 18" wheels (which I believe should be the 3LT, LTZ, and SS). Although the return address was from their "Recall Processing Center".

    Explanation: "A revised brake module calibration is available that can enhance your vehicle's antilock brake performance slightly by reducing minimum stopping distance on dry pavement. The braking performance of your vehicle meets the applicable federal safety standard and all of GM's rigorous internal requirements, but we have identified a performance improvement that we want to make available to you."

    Per the letter, Chevy will reprogram the electronic brake control module at no charge until Dec. 31, 2006. Courtesy transportation may be provided if it's within the new vehicle limited warranty.

    I'm actually glad to hear this for several reasons:

    First, I was disappointed and a little concerned to read/watch Motorweek's review of the brakes: "Braking was disappointing, however. The Impala's four-wheel-discs with optional ABS leisurely stopped in 148 feet from 60. We consider 130 feet a good result." After all, it's the always last few feet that make all the difference when you're trying to avoid a collision, not the first ones. ;)

    Second, Chevy is taking ownership of the problem and offering it proactively. Yes, they may be taking a hit now to limit any future liability, but it's a win-win for everyone.

    Remember, Chevy also made a production change in Aug. to fix the early horrible lumbar support, which is now very good indeed.

    So, say what you want about Chevy, but they seem to be doing some of the right things. Believe me, after reading the recent Ford recalls (including the one that involved weak gas tank supports!!), this is most welcome in comparison -- assuming of course that Chevy is being forthright about the real reason for the reprogramming. :confuse:
