    Good Morning All;

    I took the Malibu out in the recent snow storm with the new Michelin Tires! ------ The vehicle drives like a different car! ---- It has no problem going through snow! ----- If you want a "great performing vehicle," -- take off the Goodyear tires and install Michelin Tires! ----- GM should have installed these tires, on the vehicle, as part of the "original equipment package." ---- I purchased the "TOP OF THE LINE" (LTZ) Malibu, --- and I got "BOTTOM OF THE LINE" ($98.00 / retail), tires! ----- Help me understand this corporate logic! ---- The vehicle is a "quality product," -- but GM "dropped the ball" when they installed "cheap tires" on this vehicle! ----- WAKE UP GM! ----- Hyundai & Kia are going to take your market share. ----- Take a "hard look at their vehicles!" ----- They are producing a "quality product," and their dealers are willing to work with the customers! ---- I would bet that I could get a Hyundai or a Kia dealer to switch tires prior to delivery! ----- Just something to "think about" while you are in your corporate offices drinking coffee!

    Best regards! -------- Dwayne :shades: ;) :) :confuse:

    You think? Bought 40K Lacrosse which came with GY tires, 19" Eagle RSA. Damn. Rated pretty low compared to others of same type. They quieted after about a 1000 miles but their wet and snow performance is just bad. I'm hoping a different tire would improve ride a bit as well. Over $1200 of tires + mount, ship, etc. per tire rack. Could not get them to budge and no tire dealers wanted them. One place offered me $400.

    Good Evening:

    Replace the Good Year Tires on the Lacrosse! ------ (They are an accident looking for a place to happen!)

    I will be making a new vehicle purchase in 2012. ---- I know that the Toyota dealer will remove the Bridgestone tires, and install "original equipment Michelin tires," (without any out of pocket expenses to me!) ----- On the other hand, the Chevrolet Dealer might not be so accommodating! ----- I am going to price a 2012 Toyota V6 XLE Camry, and a 2012 LT 2 Chevrolet 3.5 V6 Impala with the same equipment and a maximum extended manufacturer's extended warranty (Zero deductible to 100,000 miles.) ------ The criteria for purchase will be: ride quality, comfort, fit & finish, body style, performance, overall quality, the trade value of my 2007 Camry, (as defined by each dealer), and the tires on the vehicle. ------ I like both vehicles. --- (If Chevrolet decided to offer the LTZ Malibu with a four cylinder Turbo like the Buick Regal, I would also take a look at the Malibu!) ----- If I had to guess, I would say that the Impala would come in as the cheaper vehicle, but I would have to factor in the cost of the Michelin tires. ----- On the other side of the issue, the Camry would have a better "trade in value" in five years, than the Impala! ----- My 2007 V6 XLE Camry is one "HOT Vehicle!" ----- (Coming out of a toll booth on the GSP I could easily stay with an average Mustang to 65mph!) --- I do not think the Impala has that kind of performance built into it with a four speed automatic.

    Best regards. ----------- Dwayne :shades: :confuse: ;) :) :D

    I test drove a 10 Impala and it seemed to be a nice handling ride. The down side seems to be that 09 was the last intended year on that platform and options had become very thin. There were some I wanted that just were not available on the Impala. But then I can say of the Lacrosse that there are some I feel should have been standard equipment especially on CSX but not even available. Air self leveling shocks on rear is definitely such.
    It is my understanding that the intent was for a new epsilon platform to be used on a new Buick Lasabre would also become the new Impala. It has been greatly delayed and won't be out till at least 2012. That would mean no Impala for a few years so they keep building the old.
    You seem to be a bit power concerned so possibly the LTZ which comes with 3.9L and probably increased gas, but more options also.

    Good Morning:

    Here are the issues:

    1.) My 2007 XLE V6 Toyota Camry easily gets 30mpg at 60mph, (on the highway), and in the process has outstanding performance.

    2.) The 3.9 Chevrolet engine is NOT a flex-fuel engine, and it does not come close to the mileage of the Camry

    3.) I think the V8 Impala has an engine that cuts out cylinders while cruising on the highway. (I will have to do some research on this issue.) ---- [I had an opportunity to drive a 2007 version of this vehicle when I was looking for a vehicle in 2007! ---- This is one "HOT" car and it sounds "HOT!"

    4.) I was hoping that the Impala would have a 6 speed automatic transmission in 2012.

    5.) I think that the Impala would look great in a dark Cherry exterior color with beige leather interior. (GM needs to "up-date" their color choices!) ---- [A dark green would also look great with a beige leather interior]

    6.) With the Camry I get both performance and mileage.

    7.) Recently, I rented an Impala and it handled very well in the snow.

    8.) If GM installs a 6 speed automatic transmission in the Impala it should be a shiftable 6 speed automatic with controls on the steering wheel! ---- (GM needs to improve and up-date the Impala line and their drive train technology!)

    7.) I have both a great GM dealer and a great Toyota dealer!

    8.) I like my 2010 LTZ Malibu, (now that I have installed Michelin tires.) ---- This car now can go "head to head" with a four cylinder Honda Accord, or a four cylinder Toyota Camry. ----- (I would like a little more punch in the GM four cylinder engine! GM offers a turbo in the Buick Regal, and this should be offered in the LTZ Malibu!)

    Best regards. --------------- Dwayne :shades: ;) :) :D

    QUESTIONS: ----- What kind of mileage do you get on the Buick Lacrosse? ----- Does it have a 6 speed automatic transmission? ----- Can you shift it manually? -------- Best regards. --------- Dwayne :shades: :confuse: ;) :)

    2, I think both the 3.5 & 3.9 became flex fuel in 2010. The Lucernne using 3.9 is flex.
    3, My stepson has SS, maybe 08. He loves it except it won't go past a gas station. About 20MPG on highway.
    4, What I find amazing is that in some cases coupling the 6 speed to an existing engine seems to lower MPG. Maybe coincidence with new EPA regs.
    5, 09 and prior had many more color choices in some GM vehicles.
    8, I found the shift paddles near useless. They are coupled with electronic control of tranny so any shift comes with a delay and if it is considered out of range it won't do it.
    Does not the LTZ come with 3.6 standard?

    Good Morning:

    Thank you for your response to my comments. ----- Kindly be advised that the LTZ Malibu comes standard with the four (4) cylinder engine, and the six (6) speed automatic transmission. ------ If I was to consider another Malibu, (and a Turbo four was not available), I would most probably go with the 3.6 V6. ----- Think of this possibility; ---- a two door Malibu with a 6 speed manual trans, with either a 4 turbo or a 3.6 V6 engine, and dual exhausts on either engine! ----- If this vehicle was offered with a deep cherry exterior it would be a "smoking machine!" ----- ARE YOU LISTENING GENERAL MOTORS ???????????? ------ Best regards. ----- Dwayne :shades: ;) :) :D

    As a follow up are the Michelins holding air better than the Goodyears? Or was it a rim problem?
  • djm2djm2 Posts: 712
    Hi All:

    I am happy to report that the Michelin tires are holding "Nitro." ---- In addition, the Michelin tires are great in the snow, unlike the Goodyear tires! ----- The ride is a little harder than the Goodyear tires. ----- The handling is very good. ---- If I decide to purchase another GM product, I will be negotiating a "trade of tires" prior to taking delivery of the new vehicle. ------ If I purchase another Malibu, I will most likely purchase the V6! ------ I just got back from Atlantic City, and the vehicle performed very well on the NJ Turnpike, and the Garden State Parkway. ----- The vehicle drives like a much heavier car with the Michelin tires. ---- Quality tires make a "BIG DIFFERENCE!" ------ I have been using premium fuel in the vehicle as an experiment. ----- It seems to be a little more powerful with the 92 octane fuel, especially when passing another vehicle on the highway! ---- I like the performance of the fuel that is sold by the "WAWA" convenience stores! ------

    Best regards. --------- Dwayne :shades: ;) :) :D :confuse:
  • I have a 4 cylinder Malibu and I have always gotten excellent gas mileage. Once in the city I got 30 MPG.
  • I have a 2010 malibu with the 6 speed automatic trans, the fuel milage is great but the motor is underpowered for the trans and when I take off the engine shudiders and shakes like it is going to fall out of the car. GM has attempted to repair the problem 3 times and has now refused to acknowledge the problem, telling me that the severve viberation is NORMAL. Buy anytihing but a GM product.
  • I purchased a new 2010 Malibu with a 4cyclinder engine and an 6 speed automatic trans and have had nothing but problems with the trans since the car was recalled last June when the car had 200 miles on it. There is a problem with this trans and it the same driveline that is in the 2011 malibu also. GM has recalibrated the trans 3 times and now tell me that what I have is the "Normal characteristics of the car". When I accelerate from a stopped postition there is a severe vibration and shuddering in the transmission. I would recomend not buying a new GM vehicle, they have failed to stand behind their product.

    Hi Truckdriving88:

    As you know from prior postings, I have a 2010 4 cylinder LTZ Malibu with a 6 speed automatic. ----- I presently have 10,000 + miles on the vehicle. (No problem outside of the original Goodyear Tires.) ---- What was you vehicle recalled for?????? ------- SUGGESTION: ----- Purchase a GM 100,000 mile "top of the line" extended warranty. (I have one on my Malibu!) ----- What is the "Lemon Law" in your State? ----- I can only get 30+ mpg if I keep the vehicle at 55 mph on the highway. ----- If I drive at 60 / 65 I get 27 mpg. -------- My other vehicle, (a 2007 V6 XLE Camry), gets 30 mpg easily at 60 / 65 mph. I have had this vehicle up to 34mpg on a long road trip! ----- GM needs to do some better engineering with regards to this engine & trans in terms of mpg! ------- Best Regards. ------------ Dwayne :shades: ;) :)

    > I can only get 30+ mpg if I keep the vehicle at 55 mph on the highway.

    Dear DJM,

    Have you tried a different brand of gasoline and used the midgrade octane level for a couple of fills to see if that changes the mileage? I find our Cobalt seems particular about some fuels and I wonder if it's higher alcohol levels in them that affects the indicated mileage.

    I-4 & AT-6 is not a rocket, but far faster than when it was couple with AT-4.
    It sounds like you have an engine problem. With this combo, some had issues with pre-cat just over a year ago causing low power. Are they trying to force you to use lemon law so they can recoup from government?
  • djm2djm2 Posts: 712
    Hi imidazol97:

    I am in the process of trying different brands of fuel and octane. ----- (Fuel does not seem to be a problem with the 2007 V6 XLE Camry. ------ I easily get 30mpg on 87 octane, "name brand" and / or "off brand fuel!") ----- The Malibu seems to be more comfortable on the highway at 55mph. ---- Once I get past 60mph, the engine seems to be working much harder. ----------- (I am not sure that the six speed automatic trans is a good combination with the four cylinder engine. ---- Maybe this vehicle should only have a five speed. The vehicle seems to "down shift" at every little opportunity, and this kills MPG! ----- The V6 Camry does not operate in this fashion! ----- There is more "leeway" between the accelerator movement and a forced downshift. ----- The Malibu's accelerator seems to be very sensitive to the slightest movement.) ----- At the higher speed, 60+ mph, keeping a very steady pedal, without using cruise control, is an effort! ----- (I do not like "cruise control"! ----- I want to drive my own vehicle!) -------- Best regards. ------------- Dwayne :shades: ;)
  • I guess, I have been dealing with representives in Detroit for 9 months trying t solve the problem, then suddenly they tell me the "Lugging" is normal and that I have to to live with the car in this condition.
  • Dwayne: Last June I took the car in for a dash problem and when I picked it up I was told that they had preformed an computer update on trans. problem recall. 2 car had 300miles on it. I drove the car 10 miles and the trans started shifting between 5th and 6th gears at 2100 causing a surging problem. The dealership told me then that GM was aware of this issue and in OCT. they provided a new recalibration and it has been all downhill from there. They tell me to just drive the car as it is and that it has a 100,000 mile warrenty and that the lugging, chugging I feel when I take off is normal.

    Hi truckdriving88:

    What is the "lemon law" like in your state? ------ I would invoke the "lemon law" ASAP! --------- Hire a "lemon law attorney" is necessary! ----- Keep us posted! --------- Your vehicle is NOT safe! ----- Best Regards! -------Dwayne ;)
  • e_net_ridere_net_rider Posts: 1,380
    There seems to be some disparity about mileage judging from complaints. the 09 LT2 I had showed me good mileage although it seemed to drop off a little as I approached 10K. On one round trip across the Smokies & about 2700 miles it showed me 29.5 MPG including about 300 miles of local driving and fast on the interstate.
    Could the disparity be related to your chugging complaint? I have noted that on many vehicles with 4 cylinder it is hard to hold a steady speed because of the tight gearing ratio for best mileage while meeting EPA requirements. And it seems to have crepted into V6 with AT6. Newer ones using VVT, DI, etc. might have more speed creep than prior models.
    Since you seem to think the tranny calibrations are making it worse, have you tried getting it calibrated back to what it was when you took delivery?
  • gmcustsvcgmcustsvc Posts: 4,251
    Can you please email me your VIN? Has your dealer involved technical assistance?
    GM Customer Service
  • I have asked the dealership to calibrate it back to what it was when I purchased it, but they refuse saying that this is the solution to a GM recall on the trans.
  • I have been involved with GM representives in Detriot at the GM ecutive offices since November 2010 and have had no resolution. I was also contacted by GM rep.s that work in Portagul and Milasia, one was rude, loud and tryed to intimidate me over the phone after I had requested that GM buyback the car, he also refused to provide me with a last name or return phone number. I am really disappointed with GM, my father was a ASE certifed mechanic at a chevy dealership his whole life and although I never made being a mechanic my profession I have restored a few Chevy Camaro's and a 57 Belair over the last few years. My family including my children have only purchased new Chevrolets. GM has lost a lifetime customer.

    Perhaps I should have guessed that would be the outcome of reprogram.
    Time to go back to square one with troubleshooting. Your complaint is lugging, chugging. I presume that means you get the feeling it is in too high a gear at start from stop? Like maybe it is in 2nd or 3rd gear?
    Can you do a few accelerations from a stop and check for gear changes? With light, medium, & heavy pedal, + maybe WOT? Also note when TCC engages.
    Note speeds & RPMs at changes. Do any of the shifts flair, that is, does the RPM increase during the release & engagement of the next higher gear?
    What happens if you attempt manually shifting?
    The big question here is with your description of problem, is it tranny or is it engine?
  • dispencer2dispencer2 Posts: 299
    I'm very sorry that the Malibu went with a 6 speed. My new car (38 miles on it) slides through the gears and feels funny -like it isn't solidly moving from gear to gear. Hard to explain - feels like the gears are slipping. My 09 Cobalt with a 4 speed automatic feels much more familiar and precisely shifts from gear to gear. The new Malibu feels slushy. GM ought to ressurect the old twin turbine Dynaflow or the Turbodrive I had in a '58 Impala where you didn't feel any shifts at all. I may suffer from a lower gas mileage with a 4 speed but I doubt it. I got 43.1 on the Cobalt coming east with a tailwind from Albuquerque to Clovis on Saturday. Wish I could have ordered a 4 speed on the Malibu.

    Hi All:

    My 2010 four cylinder Malibu LTZ with a 6 speed transmission has turned 12,500 miles, and it has developed the famous "surging issue!" ------- When going up a hill from a dead stop, or when merging into "bumper to bumper traffic" on the highway at 20mph, the engine / drivetrain surges like a manual transmission stuck in a high gear range for the vehicle speed. The engine lugs! ---- I have an appointment with the selling dealer to have the vehicle service for this problem, but I have no faith that anything can be done for this issue. ---- I think GM knows more about this problem than they are telling the customers. ----- While I have a 100,000 mile GM extended warranty on this vehicle, if this problem cannot be solved, this vehicle is HISTORY! ---- I might consult a "Lemon Law Attorney!" ----- Best regards. --------- Dwayne :lemon: :confuse: :mad:
  • djm2djm2 Posts: 712
    Hi All:

    The problem is getting more prevalent! ----- Today, I was traveling on the highway at a steady 55mph with the A/C ON. ----- When the vehicle approached a hill, and started to climb the hill the engine started to surge. -------- If feels like one of the cylinders is cutting out under load. -------- It is heat related, as you must be driving for a while before the symptoms appear. ------ I cannot wait to take this vehicle in for service. One of the ignition coils could be going bad, or I might have a problem with one of the injectors under load. ---- I will keep you posted. ---- I AM NOT A HAPPY OWNER! --------- I will be taking my Malibu in for service in the near future. ---- Best regards. ----- Dwayne :lemon: :sick: :confuse: :mad:

    I have been complaining about mine pretty much since I bought it. So I took it back in recently (now that it's out of warranty, of course) and asked them to look at both the transmission and throttle mapping.
    Now, it appears that GM has a service bulletin for the programming of the 6 speed automatic. Since being re-programmed, it has made a big difference. It has not cured all its ills, but well worth the visit and the $80 they charged me. Of course, I think they should have covered it, but didn't feel like arguing that point.

    Hi All:


    I took my 2010 four cylinder LTZ Malibu to the dealer for this problem. They took the time to troubleshoot the problem, and they found that the vehicle needed an "up-dated software package." ----- Now, the vehicle operates like a totally different car. The surging problem is gone, the acceleration is smooth and quick, and I am getting better fuel mileage. ----- From the day that I took delivery on this vehicle, I always felt that I was dragging a "sea anchor" behind the vehicle. The vehicle did not seem to roll freely. Now, after the up date, the performance has improved 100%. While I appreciate the efforts of my dealer, I feel that GM / Chevrolet dropped the ball big time, when they did not advise the owners of these vehicles that an "up-dated software package" was available for installation. ----- (Once I hit 12,000 miles the performance of my vehicle went down hill! While the vehicle did not perform as expected at first, it took 12,000 miles for the "surging issue" to surface! ---- They question is WHY? ---- What happened between delivery and 12,000 miles? ----- Did the existing software become "corrupted" while being in use? ----- Will the new software suffer the same fate in another 12,000 miles? ----- Will this be an "on-going" experience for the life of the vehicle every 12,000 miles?) ----- My dealer is OUTSTANDING! ---- I am now enjoying the vehicle. ------ Best regards. -------- Dwayne :shades: ;) :) :confuse:
