Chevy Malibu Maxx



  • e2helpere2helper Posts: 1,002
    I just don't have good idea if dealer actually tells customer what code they might read with Tech 2.


    Anyways P0116 = Engine Coolant Sensor Rationality test. I could give you details but then you know what would have to happen (LOL)


    But here is the general idea....when vehicle thinks igition has been off for a long period of time it expects engine coolant temperature to be close to ambient temperature. If it sees it as too high (it has a way to figure this out) engine computer considers there might be something wrong with coolant temp sensor so it sets that code and I think the temp gage might default to some value. Don't know if that is what you were seeing.
  • this might partly explain why the Maxx sometimes has trouble starting after being parked after warming up, it is left for a short time and then restarted. The "tween" condition appears to confuse the engine management computer and the engine gets the wrong mixture during start. Once going, the engine is fine.
  • I am interested in a maxx LS with the 1SB package Im interested to know what other people consider a fair price for this vehicle. I went to a local dealer and the MSRP is $23,213,the invoice is around $21,529 (that is what dealer gave) and there is a $3000.00 rebate (northeast). That would bring the price to $18529.00 does this seem fair or could i get this for less?? I looked on the prices paid board but there is nothing recent to go by. Your comments and advise are much appreciated. Also wondering if any other incentives are out there for this vehicle.

    You are a sharp guy, Kurt!


  • I have a 04 Maxx that has been in to the local dealer 6 times for rough idle. On the second time in, the dealer reprogrammed the ECU as per the TSB 04-06-04-080. They also did it again on the 3,4, and 5th times in. Still the same crappy rough idle till the point the MAXX idles so low it wants to shut off!!!! On the 6th time, I was told it was "a characteristic of the engine"!!!! Anyone else have this happen? I like this car;wife's car; and want this fixed. I asked them about checking the plugs and injectors or even if it was a bad ECU and all I got was the computer doesn't show anything!?!?!? I need a mechanic and not a bunch of parts changers!! Any ideas??

    for the base LS. No GM card, no current owner discount. Don't have the moroni sticker in front of me but think that the price was about 22.1 (varies slightly with manufacture date, I got a later one because I didn't want white. Could have gotten the base car with $80 floor mats who needs 'em for 15.9. Sounds like you're about a thousand too high.
  • Is yours a 2005 or 2004?? DO you remember what the rebates were in your area at the time of purchase? Thanks for your response!

    Not sure how common this is on other vehicles, but I observed something this week that impressed me about the Maxx's intermittent wipers.


    When you twist the stalk to a faster setting, the wipers immediately wipe across the windshield once - even if it wasn't time yet for them to do so. When you twist to a slower setting, this does not happen.


    The designers/engineers must have been thinking along the same lines as me - when I speed up the intermittent setting, it's because there already is enough stuff on the windshield and I want to clear it right away.


    Thumbs up!
  • e2helpere2helper Posts: 1,002
    I like that feature as well and will pass your comments along to person responsible!


    Stuff like this is possible because wipers under control of body computer with a "dumb" motor rather than a motor that is "semi-smart"
  • e2helpere2helper Posts: 1,002
    Did you notice that the intermittent delay is vehicle sensitive as well? Shorter delay when you drive faster
  • Any suggestions? Or should I just go ahead and let the dealer change the temp sending unit?


    Another strange thing happened the other day. I flipped through the DIC and noticed the MPG and avg speed had reset itself to 0 for some reason. When I had exited the car earlier, the radio continued to play 10 minutes after I shut the car off and took the key out. The only thing I did different was not use the power lock to unlock the car, but just did it manually. Did I somehow trick the computer?


    Thanks for the help.

    I don't know why it zeroed out by itself, but the 'Bu/Maxx does have ambient power reserve which means after you shut off your car and remove your key (as long as you don't open up the driver's door), you can still shut/open the sunroof, windows, listen to the radio, etc.
  • csandstecsandste Posts: 1,866
    It was an '05. I used the internet sales query through Edmunds. Two of the three dealers who I checked contacted me.


    Two kickers that probably won't apply for you. First I did get a $500 St. Louis auto show discount, second, I know a GM employee and got a driveway (some acronym) discount. The strange thing was that the GM employee discount gave me less than $100 additional as I had to forego some other discounts when I got it.


    My suspicion is that dealing with an on-line salesman does save you some bucks. Both dealers responses were almost dollar for dollar identical.


    I can't find my e-mail detailing each of the discounts but I did find the sales price and discount on a comparison spreadsheet:


    list: 22,090

    discount: 6010.50

    purchase price: 16079.50

    I should also state that Missouri sales tax is not part of the transaction price but has to be paid within 30 days. Since I get 2000 worth of credit for the car that I'm practically giving to my daughter I'll have to pay approximately a thousand dollars in sales tax before my 30 day paper tag expires ($14000 net @ 7%) and I transfer my existing plates on my Hyundai over to the Maxx. Different states do it differently. I'm always encouraging people to ignore sales tax in reporting prices paid since the practice varies so much state to state. If you had sales taxes in there as part of the deal that could go a long way towards changing your total paid.


    I could have also saved about $100 plus dollars if I had taken a car with an earlier build (about fifty different plus 80 dollars worth of floor mats). I didn't want a white car, however, and a $15 set of Wal-Mart floor mats work just fine, thank you...

    Actually "we" call it Retained Accessory Power (LOL).


    The Malibu has 2 different levels in vehicle. When you turn off the ignition you can operate windows and sunroof (and heated seats?) for up to 10 minutes until you open any door.


    The radio actually will continue to play for up to 10 minutes until driver door is opened. It doesn't shut off when passenger doors are opened. Seems like I might have posted about this before on forum and if so - sorry about that
  • e2helpere2helper Posts: 1,002
    The dealer would have to tell you which code is setting to more intelligently answer that question but since the part is pretty easy to replace I guess wouldn't hurt if that is what they want to do.


    I might have seen someone post about finding DIC reading reset before. If that happens to you often enough for it to be an annoyance you will might need to get the body computer replaced.
  • thanks for compliment. Other cars seem to have this problem as well (my toyota camry and corolla/prism with fuel injection, and my Honda accord with 3-barrel carb (it simply boiled its carb empty). Must be a hard condition to design for.
  • Yes, the wipers are one of the high points on this car. Have also been surprised the blades have lasted over a year and still work pretty well - my other cars blades only lasted 3 months!


    Unfortunately, the dealer I go to can't order a pair of blades to save their lives!

    I've been away from this board for a while, but I'm pleased to report that my 04 Maxx LS is handling western NY winter admirably. I'm absolutely baffled by all these posts about poor winter traction...I've gone through 10" of unplowed snow with absolutely no problem; this car is the answer to my winter driving prayers!


    But one little annoyance has popped up: When driving at 55-60 mph on level expressways and an outside temp of 30F or less, there is a noticeable humming sound, almost like exhaust noise. When you lift your foot off the gas (or disengage the cruise) it goes away. Has anyone else noticed this?


    I know most all cars are noisier in cold weather when running on fast idle, but what could be causing this? It's more noticeable than other cars I've driven.
  • csandstecsandste Posts: 1,866
    Eight days to 500 miles, that's about right since I averaged about 23K a year on my Elantra. First impressions about the Maxx:


    1. Initially it seemed a bit too large, but I'm adjusting to the size and the automatic. Liked the ability to throw the Elantra around (despite its rather soft suspension, but the Maxx grows on me).


    2. I'm averaging mid twenties, mixed driving. About 1 mpg less than the Elantra. Pretty good considering displacement is up by 75 percent.


    3. I was really babying it around town. Don't know whether it was because I was keeping it 2K RPM and under or whether it was the automatic, but the engine seemed almost indolent to me. Yesterday, however, I kicked it down a bit on the interstate-- still under 3500 rpm-- and this thing does have legs.


    4. So far I'm pleasantly surprised by both the oem tires and the electric steering. Thing tracks pretty damn good. Only light snow but rain traction has been good so far. Despite that, I'm aware that the tires are rated BB with a fairly low mileage rating, so I'm not expecting much.


    5. Flexibility, flexibility, flexibility. Read a review of the emerging 04 where they compared it with the last gen large Saab hatchback, interesting because of the shared platform of the much-less interesting 9-3. Why did GM make the Saabs plain jane normal and move the large hatch over to Chevy?


    6. Like all the doodads. Other than a lighted ignition ring and side air bags I'm unaware of anything this thing had that my Elantra GLS had.


    7. Noted that a forum poster on Car and Driver called the Maxx near luxury. No real complaints about fit and finish but most Japanese and some Korean cars seem to do better. Seating surfaces are less pleasing than my Elantra and it took me a long time to get used to them. Dash lighting seems a bit multi-colored. Seems to me that white lighting blends to light blue depending on where you look on dash. Blue information center doesn't clash (Elantra GT combines green and purple), but more attention to uniformity would have given it a better look.


    If someone told me six weeks ago that I'd buy this car I wouldn't have believed them. My first test drive wasn't that impressive, probably because cars of this size with automatics are new to me. The Maxx is growing on me daily, however. The combination of plain jane, easy to fix anywhere mechanicals and funky off the wall styling clues is appealing more and more.
  • Hey csandste...I traded in an '01 Elantra on this '05 Maxx..I loved the little Hyundai(a 5 spd also) but it had a high speed shimmy that they could not eliminate, and I got a good deal on the trade in on the Maxx LS(side airbags, rear wiper, in dash CD).

     Like you, I was getting mid 20's mileage about town..the Maxx gets 20-22..Quite acceptable.

     It is amazingly fast..and smooth and quiet..

     An earlier post mentions how good it is in the snow..I also find it excellent in the snow, here in upstate NY where we have a had quite a bit this year..Anyway.. Just thought I'd mention our similar experiences..Good luck...I love this car.

  • paopao Posts: 1,867
    Maxx LT fully loaded less engine heater and 6 disc CD player.....17.5k on the car now....routine maintenance, oil changes very 3k, change the wipers....havent rotated the tires so bad there..but the OEM bridgestones have shown little wear at all.. only minor noticeable wear on the front..none on the back..mostly highway miles....up and down east coast I-95 and I-85..still averaging in the high 20's on the road...30 on a good day......


    I know you see more complaints on the board here than praise, however that is to be problems on this Maxx at all with a build date of 2/17/04...only thing I havent had done is the TSB for the rear shades...I just leave them open and seldom are the rear seats used for people...I have had no PCM reflashes done...and the car is running so smooth...the acceleration is remarkable for this car and the long drive comfort is excellent...for the price out the door I excellent value after one year of ownership..

    Does your oil life computer show that's necessary? I'm a constant poster to bobistheoilguy and so spend a lot of time thinking about oil. I got a great UOA using 10w30 SuperTech oil on a 4000 mile sequence and the 2 liter Elantra was probably a lot tougher on the oil than that big 3.5 liter six. I later switched to 5w30 Pennzoil and was so impressed that I decided to keep that weight in for nine months a year rather than six months (Hyundai calls for thicker oil than GM).


    Most 5w30 will shear down to a mid twenty weight if you push it to 4000 miles but I don't think it's that big a problem. Plus some of those new SM oils like Conoco/Phillips and Exxon/Mobil are actually selling group III oils for a buck and a half a quart. If Pennzoil is still group II+ it's an awfully good oil anyway.


    I plan to pay attention to my oil life indicator which will probably indicate a 5000 oil change interval in mixed driving. I plan on driving the oil down to at least 10% oil life remaining.


    I've only gone back about six months in the Maxx boards. Has there been any discussion here or anywhere that the Chevy indicator (which seems pretty sophisticated) isn't giving good data?
  • csandstecsandste Posts: 1,866
    Don't want to get off the subject, but my Elantra shimmy was cured by Wal-Mart (gag)... I bought the $7 lifetime balance and rotation and they fixed my problems first time in. The typical tire place sees a lot more tire problems than the typical dealer, sometimes they can get it when the dealer doesn't. On the otherhand the guy who fixed my problem was one of the few really competant people working in our local Wal-Mart, maybe I just lucked out.


    My Elantra was also an '01 and I remember lots of discussion on wheel shimmy at that time. The OEM Maxx tires seem to be a lot better than the Elantra's Michelin Energies IMHO, although the BB rating and rather low 380 treadwear rating (from memory) seem a bit mediocre to me. Low rolling resistance at the expense of traction probably gives it a slightly higer EPA mileage rating.


    Hyundai was probably shooting for a name brand high end tire, although they'd probably done better if they'd stayed with Kumho/Hankook.

    <Has there been any discussion here or anywhere that the Chevy oil indicator (which seems pretty sophisticated) isn't giving good data?>


    My wife's car ('05 LS Maxx w/1SB) has 1785 miles on it. We picked it up with 2 miles on odometer on 10/18. She doesn't drive much. Every couple of weeks I take it out to boil the stuff out of it. The oil life indicator just dropped to 59% - so it at least knows about short drive cycles.
  • maxx4memaxx4me Posts: 1,340
    I've been doing 6k with Mobil 1. It is curious; my oil life indicater this time will drop to zero right around the 6k mark. Does the 'Bu/Maxx's computer base the mileage left on driving habits, or does it pick up on the fact that I am zeroing it out every 6k??
  • e2helpere2helper Posts: 1,002
    It is based on driving conditions. Use of something like Mobile 1 isn't taken into consideration (and the oil life system can't tell what type of oil is being used).


    Only on vehicles that are specified to use synthetic oil is the system calibrated for it (sorry)

    "GRAND BLANC, Mich. (April 1, 2004) &#151; How frequently should drivers change their engine oil? simplified_maintenance_040104.html


    Most technicians will say 3,000 miles while others say 5,000 or 7,000. But ask Mr. Goodwrench and he'll offer a simple solution &#150; let your vehicle tell you when - that could protect your wallet and the environment from unnecessary oil changes. GM's patented Oil Life System (GMOLS) can double or even triple the time between oil changes when compared to the common 3,000-mile recommendation simply by evaluating driving conditions."
  • GM had yet another of its AutoDrive fests near me so I spent the day driving 'Slades, SSR's, Ion Redlines, Cobalts, Corvette, Mercedes and Hummers. The fest's on its way to San Diego and then Flordia. Nothing made me want to trade in the Maxx.


    Also got to drive the '05 maxx LT with sunroof and all the goodies. Didn't see or feel any huge changes from '04 but noted rattles from the sunroof and back when hitting the rut/speedbump simulators. In other words, no need to trade in on this either!!!


    Can also add the Cobalt was far more refined and composed than the Ion
  • townhometownhome Posts: 104
    Kurtamaxxguy, how do I get to go to one of those AutoDrive things? Do I have to be invited or can I sign up on some website?
  • paopao Posts: 1,867
    Im still a 3k oil changer...sometimes it goes longer.....this time with travel etc..Im at 4k on this oil about 55% life left on the GMOL....Im just old fashion I guess so I do change the oil regularly..usually within the 3-5K range....both normally closer to 3K...I dont do a lot of stop and go traffic, most of mine is highway miles..did 600 this could probably stretch 6-7k out of an oil change....guess peace of mind is back to my 3K. There hasnt been any discussion here that the GMOL gives bad data...guess simply old habits are hard to break......
