#112 of 272 Re: 2007 IMPALA SS HANDLING PROBLEM [zedo6]
Jan 25, 2008 (10:56 am)
I have a 2006 Impala 2LT with the 3.5L V6...no ABS...no traction control. My car is perfectly stable in the snow. I still have the OEM Goodyear Integrity all-season tires on it and even with over 21,000 miles on them the car had no issues in our last snowstorm (2"-3" on untreated roads). My car is actually better handling in snow than it is in a rainstorm.
The Federal Government has mandated that all vehicles have a stability control system as standard equipment by 2012, and starting in 2009 must be in 55% of all new vehicles.
GM isn't adding Stabilitrak because of a flaw in the Impala's handling, they are doing it to remain competitive with other manufacturers and to start meeting Federal requirements.
When Car and Driver tested an Impala SS, they made specific comments about the suspension and they way it goes about doing it's job. They said in June 2006:
"Part of the reason the Impala SS feels so uncomfortable with the V-8ís power is that it doesnít benefit from all the chassis tweaks bestowed on the Grand Prix GXP. Opt for the Chevy, and you donít get the Pontiacís wider front wheels and sticky Bridgestone tires, Bilstein shocks, and larger brakes. Although the SSís chassis gets its own special anti-roll bars, bushings, and shock and spring rates, the suspension simply monkeys around too much. Any sporting input is foiled by a mess of undamped and uncontrolled body motions. Dive, squat, and roll control could be described as nautical. Hit the firm, easily modulated brake pedal hard, and the SSís nose dives toward the pavement. A stop from 70 mph used up only 172 feet, a couple of feet better than the larger-braked GXP could muster."

> Since I don't own a 6 cylinder, I can only comment on the SS. I also own a 2000 Bonneville SSei with Stabilitrac and never had the problem in the snow. The SS was fine when I first bought it. And, now it has excessive body roll and becomes amplified
in the snow. I don't believe that GM put Stabilitrac on the SS due to competition
or gov mandate. It's is my opinion that the handling goes off due to the transfer of engine torque. It wobbles and when you introduce snow, it amplifies the problem.
In my opinion, Stabilitrac was added to help cure the problems that I write.

You make it sound as though Stabilitrak was added to address an alleged handling problem with the Impala. It is not just the SS models, or only the Impala, that received standard Stabilitrak for 2008. GM has added it as standard equipment on many of the 2008 models.
If the handling of the car was truly that dangerous in the snow, Chevrolet would either be voluntarily recalling all Impalas to address the "problem" or they would be required by the Government to recall and fix any "problem".
GM has added it purely to meet Federal Government requirements, GM even states such on their own website:
"The government will require electronic stability control on all new cars and trucks by 2012. GM will have StabiliTrak standard on nearly all vehicles sold to retail customers by the end of 2010."
While I agree that tautness of the suspension on the Impala degrades quickly, I would not consider it a problem. The Impala is what it is, a family sedan more intended for long distance cruising than canyon carving. It sounds like you may be trying to get more out of it than it is ultimately intended for.
Your plan to enhance the suspension may be the answer you to your concern. It could be a simple strut tower brace, and some better tires, would solve your issues.

> I don't know how you can comment on the problem (not aledged) that I'm having with my SS when you have a 6 cylinder. My problem is everyday driving and NOT CANYON CARVING. If I want to do that I'll do that in my CORVETTE. I suppose you can quote an article from Motor Trend to tell me how that's suppose to handle too. I wrote this forum to see if anyone else with an SS is having a problem. And, it will be going back to GM. Tires won't cure body roll. And, it's gracious of you to acknowledge the possible softning of the suspension.

I've had my 2006 SS since June of '06 and there has been no degradation of handling whatsoever. The car handles fine and I have no complaints. The Car and Driver description of the handling is highly inaccurate in my experience.

You misinterpreted my comments. I was trying to get the point across that the Impala (V6 or V8) is a cruiser that will perform best on the Interstate. As soon as it is asked to start shifting its weight around, whether on dry or wet roads, it is going to start to get grumpy.
The Car and Driver article I quoted actually supported your concern and merely pointed out that what you are noticing with your SS has been noticed by others. What you are noticing is not necessarily unique.
I suggested to you both a strut tower brace and new tires. The strut tower brace will minimize the body roll you are experiencing. The Goodyear Eagle RS-A tires that come on the SS are not the best tires. I have had them on cars I have owned and they are not the performance tires they pretend to be. They ride too much on the soft side, which will soften up your ride. A strut tower brace and some ultra high performance tires (with stiffer sidewalls than the RS-A's) will go a long way toward making your SS handle tighter.
#118 of 272 Three problems to report
Jan 29, 2008 (6:56 am)
I have a 2007 Impala LS with the 3.5L V-6. Overall it has been a good car but still has its niggling problems. I bought it in April 07 as a fleet vehicle. It had 18000 miles on it with no Onstar and no folding rear bench... in other words no extras. I do have decent gas mileage though if I am on the highway. Straight city in winter 15 mpg, in summer 18 mpg, highway only as high as 39 mpg indicated on the computer (Not really that high at gas pump) when it used straight gas and not 10% alcohol. Right now with a mix plus some hillyness I am getting between 26 and 28 mpg. I do have the Integrity tires but hate them as the spin easy when starting off on wet or snowy roads. Once up to speed they work great. I keep mine at 32 psi though instead of the indicated 30 psi for each.
The number 1 problem I am most frustrated with is the tranny. When trying to start out slowly to keep its fuel mileage up and to keep from spinning the tires I find the tranny shifts into second gear too soon. This causes a drop of the rpms to idle speed as it shifts to second. This causes the engine to bog and me to get heated. I might as well just put it in second at every stop. According to my GM dealer its working as its supposed to. If you are on the gas it works fine but if you try to start out slowly forget it.
Number 2 on the list is there is no light in the trunk. This is so frustrating when you are unloading a deep trunk like in this car. Was a light offered in the normal cars??
Number 3 is a real annoyance that just started happening. When I plug in something to the accessory power ports and they are first charging up i.e. IPOD with a dead battery and then go to start the car I get nothing at all. The second time I turn the key it starts fine. But every time I plug in the accessory this happens unless there is very little draw on the accessory port. Like when it finally charges completely. If nothing is plugged in then all is fine.
Had it to the shop and all worked normal for them neither of us knew about the accessory drain. Going in today with a note for them to check the accessory port trick with my drained IPOD. We will see what happens. I wouldn't have thought an IPOD or bluetooth device would have enough of a drain to kill the electrical system of a battery with how many cca? I mean there isn't any clicks at all but the lights go dim and the fan shuts off and everything dies. Turn the key again and all is normal.
This is the last GM I buy. I have had an Olds that had a bad distributor from day one for years. Talk about torque steer. It was a fun car but not reliable at all. I had a Chevy Monte Carlo with a Carb and Choke problem, I have had a Jeep Cherokee Sport (rear diff was bad at 36000 miles), Grand Cherokee (Had every problem in book), Brother has a 96 Ford F150 (Front wheel bearing and axle bad at 30000 miles) and he doesn't off road it, had a Sonoma extended cab (Never had traction, front shock was bad, bad seat release lever, blew the valve cover gasket and burned oil like crazy all within 20000 miles), had an 01 Blazer 4X4 4-door (You name it it happened to this vehicle, Wheel bearings, upper and lower ball joints, oil cooler lines blew, shocks gone, springs shot, ate gas filters, brakes always smelled liked they were burning but the culprit never found, had a wild shake above 65 that no one could find, brake dust shields rusted out twice in less than 50000 miles, a bad battery), and now this one.
Oh I forgot to mention that this Impala also suffers from the dreaded paint chipping problem that almost all the reds cars and some other color cars have.
At least with Honda the workers seem to have pride in making their cars. I still have problems thinking of a high school graduate making $27 a hour or more just to turn one screw on every car taht goes by on the assembly line all day long. That job may not exist anymore but the price some of the union workers are getting paid are a little unreasonable. No wonder GM and Ford have to keep cutting costs, taking short cuts, and raising prices.

I meant my brother has a 2006 Ford F150 with those front end problems and his tires are almost worn out to boot because of the severness of the wheel bearing and axle problem the front end was out of alignment.

I'm "only" a high school graduate, but I make $90.00 an hour in cars' engine compartments.

> I'm taking it in on Monday for Chevy to take a look. I was getting the impression from you that I HEAL and TOE my way to work. I don't but I do like V8's. Since I haven't driven a 6cyln, I don't know how it feels. Frontal traction is good in the snow but as it's pulling at safe speeds, the backend moves around when the road is not that bad as far as snow coverage. Ever seen a plane landing in a cross wind? You have to keep correcting the wheel to keep it straight. The torque that V8 produces seems like if it
needs another top gear at any speed wet or dry. I like that feeling but sometimes I think that the constant load it creates doesn't follow well to the back end. My Bonne SSEi which is a 6cyln doesn't exhibit any problems even after 140k. I will look into tires before next winter but I'll just ride these out this year. As far as Stabilitrac, in principle, should cure what ails the SS. That's why I was curious about the 2008. I understand that 2008 will be the last year for this body style with the 2009 going to rear wheel drive. I'll let you know what Mr. Goodwrench says.
