2007 Chevrolet Impala



  • Hello all. At 97K and the transmission showing early signs of the same problem everyone else is having, I jettisoned the Impala in favor of a 2010 Malibu LTZ. Another GM product, but I'm willing to be a glutton for punishment. I've joined and will be signing onto the '10 'Bu forum here as well. Thanks to all who got to read of my issues with the Imp and replied over the last few years. I'm going to stick around as I'm interested in how everyone else's issues pan out. Take care... Peace, John
  • Reference Case 211 Involving Impala Transmission. You had asked for information on my father's Impala Vin Number. 2G1WD58G479104784
    You also asked me which dealership I had taken it to here in Knoxville. Unfortunately, since I brought daddy's car back to Knoxville in 2008, I have taken it to the two closest chevy dealerships to me and I have been very disappointed in the service departments of both of them.
    Once when I had an issue of a second battery dying within a year, they checked out the car and refused to believe it was the battery. Their answer to me was to let it die somewhere and have it towed in where they could figure out the problem. Fortunately, I did not fall off the turnip truck yesterday and chose to just get a reputable mechanic to install the new battery. It worked fine. (Reeder)
    The other dealership has failed to do the basic maintenance items I asked them to do. (I checked after they finished on things like checking fluids to see if they had been refilled and so forth.) They had not, but yet they had checked off these functions.)(Beaty)

    As a result, I am recording this issue with you and ask before I take it in to a dealership, they are made aware in advance of this problem with the Impala so that I do not have to go through a whole new set of hurdles in proving my problem with a car that is no longer in warranty. (Women are treated like idiots in both of these dealerships)
    Best Regards
  • We have 110,000 miles on our chevy and the head gaskit has gone out. What a kick in the shorts, 3 months and 10,000 miles after warrenty. Has anyone had this problem? We had the water pump changed at 60,000 and intake manifold at about 70,000. No warning this was going to happen.Had it into the dealership at 99,000 miles and they said it was fine. They say it will be about a week and $1500.00. We are on a budget as we are elderly and my wife(78) is handicapped. We bought the vehicle new thinking it would be our last new purchase. The gas millage is wonderful tho. Always get 29+ mpg... Being a disabled vet (82) this vehicle is so easy for both of us to get in and out of. Sure hope someone can let me know if this is common in this vehicle. Thank you

    You probably have the 3500 V6. Head gaskets and cross over pipe gaskets are common problems with this engine. You should check if they're replacing the cross over pipe gasket as well. Also, they need to check the specs on the cylinder head to see if it has warped. If so, then it needs to go to a machine shop to be reconditioned. I have an Uplander with the 3900 V6, a similar engine in design . Head and cross over pipe gaskets failed twice. First time the dealer that I bought the vehicle from did not do a good job and it was leaking again in less than 10k miles. Second dealer had the heads machined and it has been good for about 15k miles with no leaks since the repair. My engine runs strong and does not burn oil. I have 80k miles. Good luck.

  • Do not buy their warranties unless you read every little detail in the contract. If you are in another city and require work, GM can disavow working on your vehicle by having their mechanics profess that someone else caused the problem to your car. I have just went through this with my 2007 SS Impala.
    Also, if the problem involves your transmission, do not accept the cheaper option of putting in a new transmission with a three year warranty. You will experience the same problem in a couple of years and pay for it all over again. These transmissions have an unusual flaw that can only be fixed by breaking it down. I have just found this out the hard way.
    Do not buy a gm car!! (from a family who worked and owned GM cars for many many years.)
  • The bailout does not change a poor design and quality process, GM has a flaw(causes slippage) with these transmissions that typical occur in the 55K-65K region, this is just another problem, also the front door speakers are dead, the remote only works from 10 feet due to receiver being blown out by static electricity, and the brakes are the worse, very undersized. I am shopping the competition today, never buying a GM again, done after 30 years.....previously I owned a 2001 Impala that went through the 6 re-designs of the intake manifold gasket, sad story, sad company, stay away from them.
  • I have a 2007 impala ls and recently the check engine light came on, it happened about a month ago and then went off , i tried tightening the gas gap and it seemed to go off shortly after that for a while until I filled up with gas again and after about using a quarter tank the light came back on, was wondering if you had any insight or suggestions.
  • Greets. A couple of ideas for you. first, clean the gasket and filler neck surfaces completely free of the blackish buildup to promote a good seal. If that doesn't work, there is a solenoid in the rear drivers fenderwell behind the filler neck that can be accessed easily by removing the rear tire. This is notorious for failing, and will throw a code, P0440 or P0449 IIRC. On mine, i opted to pull it, shot some WD40 into it, used a 12 volt battery to cycle it several times, reinstalled, and never had another problem with it. Others have just replaced it. Once accessed, it's only held in with one 10 mm bolt. I'd strongly suggest joining an online forum called NAIOA, It is one of the best W-body forums around, of which I am still a member even though my Imp has been gone for a few months now. Great information, and the guys there are very helpful. Good Luck with yours. Peace, John

  • Sarah,

    I have a 2006 Chevy Impala SS I bought with with about 75k on it, and it has about 95k to date. I have had a water pump, two batteries, two tire press. sensors, ventilation system servos, broken wire to the tranny lock, and 3 wheel bearings replaced. Add to that, the parking brake won't stay in adjustment, the b-pillars are silvering, consumes a quart+ of oil per change, and the transmission slips.

    Compare that to the 1991 Caprice Classic it replaced with over 400k miles on it that still ran great but failed the NOX test by 12 points. I got 175k miles per tranny rebuild, about the same duration from water pumps, it burned 1/2 quart of oil at retirement, was never rebuilt, and still had the original starter.

    I think I need to come run your engineering-design quality processes for you.

    By the way, the transmission slipping started immediately after getting a tranny flush, and predominately happens in cold weather at low idle speeds (500 rpm range), the bands/clutch grips when the rpms get to about 800, which would indicate to me it's a sticking hydraulic servos (if this car even has them). - JB

    Tonight, while trying to pull out of work, my transmission seemed to go right in the middle of oncoming traffic. I was pushing on the gas but nothing. I would hit the gas, the RPMs would rev, but i could not move. Cutting it way too close for comfort, at the last minute, my car jolted forward. When i finally made it across traffic, I had to pull off the side of road to collect myself. I finally make it home after driving 40 mph with my blinkers on the highway. I ask my boyfriend to check all the normal fluids. Everything checks out good. He tries to move the car, but it wont move in reverse or drive. He then tells me the transmissions shot! Dont get me wrong, I am very thankful i made it home from work in one piece. What i am not thankful is coming home and getting on the computer to see how many other people have had their tranmissions go in their Impalas. I am a single working mother who bought Chevy because my father instilled in me that American made is always the way to go. Even though everyone else told me to buy Toyota or Honda. This was my first brand new car. It has 115,000 miles (of course out of warrany) on it and I am looking at a lot of $$$$ to repair that i dont have. This will be the last Chevy I own. It is sadly disappointing to say.

    This happened to me after my friend and I ate dinner. Today I was able to get my hand underneath the console, found the solenoid, pushed it in and voila the car was able to shift out of park. After watching a video on YouTube, I was able to remove the trim around the shifter and was able to see that one of the wires is broken. I am unable to remove the console itself though. According to the video if you remove the tray in the compartment bin there should be 4 screws in the bottom. There are no screws in the bottom of my compartment bin. If there are, they are hidden underneath. Anyway, if I can get this center console removed, my friend can replace the brokern wire. Any suggestions? :confuse:

  • Yes Sarah, And, since I made my original post, I have had both a battery and alternator replaced. That's the 3rd battery since buying it 22 Oct 2010. I am on a first name basis with the dispatcher at the towing company. And, being unemployed for three years, I keep hoping that each repair I perform is the last for a while, instead of just biting the bullet and selling the thing.

    I am in denial that, after 6 previous Impalas that were absolutely great cars; all those Failure Mode Effects Analysis, 6-Sigma, Automotive Parts Quality Process, Design for Assembly, Design for Manufacture, Process Control Charts, Risk and Opportunity Management, ANSI/ASME GDT, processes used by GM's "best in class" college educated engineers... have yielded such utter garbage.

    Hi Sarah,

    I saw your posting on a website in regards to Chevy Impala issues... I have to vent here and hopefully this catches someones ear and they're able to assist with these very annoying and expensive problems my wife and I have been having with her Impala for about 2 years now...

    Here is some details about the vehicle -

    We're the original owners
    Purchased new in 2007 from Crane Chevy in Clifton, NJ
    2007 Chevy Impala LTZ
    VIN # - 2G1WU58R579315819
    Mileage just hit 50,000 miles
    My wife drives this car about 12 miles total each day to and from work

    Problems -

    1) Brakes - Over a period of about 25,000 miles we've experienced severe steering wheel shaking when braking at any speed. Originally a Chevy mechanic (working for Bellavia Chevy in East Rutherford, NJ) cut the rotors and replaced the brake pads about 3 years ago in efforts to resolve this problem. About a year ago the problem returned so I replaced the rotors completely as well as the brake pads again even though the current ones seemed just fine I didn't want anything left over from the previous issue. The problem seemed to have gone away for about a month and a half and then came back. Ever since the issue has been getting progressively worse and just this past weekend I took it one step further and replaced both from calipers, rotors (again) and brake pads (again even though the others didn't look worn) again to not have anything existing left over... As of right now, about 3 days after the repairs were completed the car seems to brake like it should and without any steering wheel shake what so ever. But remember... this happened both of the other times that brake work was done on this car and then the issues quickly came back... I've read on other forums that this seems to be an issue with or year Chevy Impala and that heat is the utimate issue... Not sure how true that is but every time the car has been taken to the dealership they tell us 'Oh just replace the rotors and pads and you'll be fine'... Then we explain that we've done that twice already in the past two years, now along with calipers too! The technicians are then speechless and have nothing else to say.... We're at a total loss if this vehicle starts to do this again after replacing everything brake related up front this past weekend...

    2) Transmission - Just recently, about 2 months ago is when my wife first experienced this issue. She'd hit the gas to pull away from a parking spot or to cross an intersection and the car would rev and then bang into gear and pull away. This issue also seems to now happen during driving the vehicle too and not only from a dead stop. It seems like something is slipping and we're told (by our chevy mechanic friend) that all fluid levels look good and nothing seems to be burnt but that this seems like an internal transmission problem that could be costly... I've read on several forums that many other people are experiencing the same exact thing but do not seem to have posted any resolution...

    We really need to figure these two problems out fast. I'm loosing my patience with this vehicle. My wife and I really like the car but i'm pushing to get rid of this car if we cannot figure out these issues. We continue to waste money on things that should not be happening...

    Any help would be appreciated.

    Thank you!

    Joseph and Rosanna

  • I Have a 2007 Impala SS with 86K miles on the car and just today had the car shuttering or shaking every time the transmission shifted up through the gears. I have no check engine light on the dash and there isn't any type of unusual noise coming from the motor or transmission. I checked the fluids and nothing was low and it didn't smell burnt which usually means the clutch isn't worn out. Does anyone have any information on what this could be of if this happened to someone else what you had to do to get it fixed.

  • Thanks Laura,

    I will get that info for you tonight. I will add that I took the car our for a spin at lunch today and everything seemed to be working just fine, both in drive and manually shifting through the gears. The car was responsive and shifted smoothly every single time. I will update you if anything changes or if I have anything else happen.

  • I too have to join this group of very upset and hurt owners of a 2007 Chevy Impala SS bought brand new off the dealer's lot. I've had to replace the transmission and now have to replace it again at the cost of $4,200.00. The dealer is saying it's because of the mileage and the warranty expiration date of October 16, 2013. I had the car towed to the dealer on November 4, 2013. I asked GMC if they would pay for some of the cost because I believe the problem is a defect in this model. I've had to replace tires after owning it for one year and now is on my second set of new tires after buying many used ones in between the years. I found out today that GMC nor the dealer will pay for none of the repair costs even after GMC customer rep Brandy at 1-866-790-5700 ext. 21206 said they would pay for some but didn't know how much they would pay. In the meantime the dealer said they would break down the transmission at the cost of $1,500.00. So now I have a car without a transmission at all and I don't have $4,200.00 to pay for another transmission and have to have it towed for storage or leave it at my loss. I am appauled at GMC and Chevy dealership Hilltop Richmond in Richmond, CA's decision and lack of fairness. The mileage on the car is from highway miles which were accumulated from Soccer tournaments and games not street miles which is hard on a transmission. I think we all should beg the mercy of an attorney to take on GMC with a class action lawsuit. Times are too hard for large companies to keep getting away with dismissing us once we've paid our cars off.
  • My wife and I just bought the 2007 3.5 LS Impala used 99,000 miles not even 8 months we have it starter went, tire ware terrible and yea we got alignment twice just in case now water pump going , oil pressure low stop engine now going off , dealer thought it was a sensor, changed it now the same thing happens but it goes off twice as long and much more frequent than before ,checked the air cleaner pulled the fuses with nothing working hoping to reset issue codes no luck ..Checked for leaky gaskets oil In the antifreeze and vice versa I have a warranty, I think the dealer that I bought the car off of is stalling for the warranty to run out in a couple of months he knows something is up or rather she was bitching cause it was the third time we had the car back in a month should I trust them ???when I bought the car it needed new breaks and Rotors I should say my wife went and picked it out I was away at work for the week or that never would of gotten by me I check everything car-fax not much trust in that but every little bit helps paper work for wrecks ,regular schedule maintenance reports you get my point I think they know a head gasket is blown or worse ....another problem I can feel brewing I can feel a delay when I pull out it won't go for a second and then sometimes gets to much power anyone have any ideas on that one ???
