    2012 Impala review from someone who had a '09 & '11...gearing kills the '12

    My company car is an Impala LT, and this is my third and I've liked them all. I run them to @ 65,000 mi. The two previous were 3.5's and they had good power off the line, but fell flat after that. But overall I found them adequate. I averaged 27mpg with them.

    I've got @ 1,200 mi on my '12 w/ 3.6, and wanted to vent about it. In a roll-on situation it's a beast. Great power, smooth, and the engine is so quiet I hardly know its running. The six speed is great, with little gear hunting. But...that darned tall gear ratio kills it off the line. It's actually almost a dog off the line. I actually hate pullling out in front of people at times. The 3.5 was not like this at all. It had grunt off the line.

    But what is really bad is in reverse. If you have to back up a hill, it almost WILL NOT GO. I had to pull into a fairly steep driveway the other day and - and I am not kidding - almost had to floor it to get it to back up. The engine revved and the torque converter just whined. Even on small inclines the tranny groans in reverse and you really have to gas it to go. To those that may not know better, you actually think something is wrong with the transmission.

    Anyway, just passing it along. If the 3.6 had the 3.5's gearing, it would be awesome. The gearing just takes the balls out of it, and in some situations give some real funtional issues.

    As someone who has logged countless hours in many of the W-Bodies over the past two decades, including a trip this Spring with a 2012 Impala, I'd recommend you taking your car in to get the tranny checked... Off the line, the 2012 was a beast compared to the old 3.5 in the two I've driven... Not even close... The numbers around the net for 0-60 times backs up my observations...

    Seriously, get that tranny checked... There should be no hesitation when stepping on the gas with the 3.6...

    Or is the traction control kicking in?

    Perhaps I'm not describing it correctly. There is no hesitation, it's just the tall gearing. Go take a '12 and try to back up a hill. I know, kind of a rare situation for some, but an everyday thing for me. Like I said, the 3.6 IS fast and faster overall than the 3.5 by a long shot. But off the bottom, the 3.5 hits harder when you punch the gas...and others here have said the same thing.

    My aunt has a new 2012 Impala and complained about the same thing. I live in a rural area in SWVA so inclined driveways are just a part of life. She drives for her job, and one of her patients has a long, inclined driveway, and she actually backs around in his yard to turn to drive out because of the gearing.

    It's not the gearing. The 2012 ratios show 3.6 2nd is near the 3.5 1st gear OAGR, and the 6-speed 3rd & 4th split the difference in the 3.5 2nd gear ratio.
    First gear in the 6-speed is a stump-puller.

    Computer program problem?

    Yea, I don't understand. The 3.6 when said and done is actually more aggressive than the 3.5 in gearing, because of the 6-speed.

    Thank you for backing me up Suzibob! I mean, here we have a report that a customer has to change the way they drive to deal with it! Again, you must be on a slope to really see this. I agree that on paper there does not seem to be a big difference in gearing. It could be in the torque converter, but I don't think so. However, it does drive somewhat like a vehicle with a high-stall converter. That wouldn't show up in the specs.

    Another annoying thing - the torque management cuts the fuel at every shift. That feels weird, and again that did not happen on the 3.5. In hard acceleration it feels a little like what a manual transmission feels like when you lift the throttle to shift and then press it again after the shift. It's weird.

    Make no mistakes, I love the car, and there is no better car for the field salesman.

    The LaCrosse is the same way. Not bad in any way, but in reverse it feels like the park brake is on when you are used to something like my Silverado.

    That is interesting. I wonder if there is something wrong with the torque converter. It seems like there should be zero issues with dead spots.

    The 3.5 might hit harder but the 3.6 is probably much faster but just doesn't feel like it.
    Just that time again to ignore certain people. I'm certain they will continue to try and instigate and antagonize while throwing up their arms saying they did nothing but are here on a civil basis. Not worth the time seeing how some just seem to know all.

    Re: 2012 Impala review from someone who had a '09 & '11...gearing kills the '12

    My wife and I have a 2012 Impala LTZ. We previouisly owned a 2008 & 2011 Impala LTZ (both with the 3.9L V-6 and the 4-speed automatic transmission, both purchased new).

    We like the 3.6 engine and 6-speed transmission much better - and it gets better mileage in town and on the highway than the two previouis cars (the 2008 had the Active Fuel Management system also). But......

    However, we have both noticed that when we back into our level driveway from the street, to back about 110 feet to the garage, the cars seems to not want to back-up smoothly. When the accelerator pedal is pushed, the car does not move and it makes the driver think the transmission is not in reverse. You then must depress the accelerator much further to get the car to back-up and it lurches backwards.

    The amount of accelerator pedal travel needed to get the car to back-up in reverse is much more than the pedal travel needed to have the car drive-away in forward from a stop. This is not backing uphill, but on a level paved driveway.

    We have also noticed that when we drive away from a stop and the car reaches about 2,000 RPM, it makes a brief "vacuum cleaner" noise - a very high pitched whine. If the accelerator pedal is released or depressed further, the noise stops. You can purposely try to maintain the RPM and the noise will continue. This sound is very, very annoying and can be heard inside the car with the windows up and the radio on. This is a normal drive-away, not an aggressive acceleration from a stop.

    When you put it in LaCrosse terms, I think I get what you mean. If you put a LaCrosse in drive, it acts fine, but I notice when I'm backing a LaCrosse into a space, I do seem to need to push on the gas much more than I should have to in order for it to move. If memory serves correctly, the Acadia/Enclave are very similar if not worse. When you are backing up with a Lambda from my experience..you think its grossly overweight because it doesn't want to move.

    Maybe the extra-effort reverse is an attempt to avoid UA issues, such as driving into the beauty parlor or supermarket.
