Chevrolet Aveo Engine Problems



  • My wife and I bought a new 07 aveo last june and didn't have any problems with it until recently. The same thing was happening to us the brake and battery lights were coming on and the brake wasn't engaged. It finally got to the point where the car was dieing on us and we had to keep having it towed to the service center. They could not find out what was wrong with it at first, but eventually they replaced the battery, the ignition switch and finally the alternator ( in that order) since they replaced the alternator we haven't had any problems. Chevy has really ticked me off with this one. It's very unlikely that I'll buy a chevy again.

    Hey, Poncho167...

    My daughter is looking at a new Toyota, and I have seen several comments from you in these feeds that Toyota attempts to convince owners that a lot of problems are "normal service items" instead of actual failures/problems. She has a Corolla now, and has had good luck, with no trips for anything other than normal service on her current car (ie, oil changes,etc).

    Is there a publication (or web-sites, etc.) that I can get more detailed info on this phenomenon?

  • poncho167poncho167 Posts: 1,178
    I would use a search engine such as google to see if the corporate information regarding this is listed. The recent engine sludge problem was another example of this and Toyota ended up taking responsibility for that after lawsuits were presented. I have read about it numerous times on blogs though I have not seen the official corporate letter to dealer service. Doing a brief search this morning just came up with normal wear and tear information which was part of what they are saying but I didn't see what those items were in the search.

    Here's the link to a site discussing the oil sludge settlement...
  • Do you have an immobilizer on this car? One of the things an immobilizer does is cut off the fuel supply so that you can't start the car without a programmed key. It's possible that they key or the immobilizer module isn't working right. Have you tried another key?

    My car has some kind of issue where it "hiccups" when you start it. It only started recently after I changed my spark plugs and wires. It seems to be getting better. I noticed that there is a loud thump coming from the back on the car when it "hiccups", too. Then, the car will run absolutely perfectly for about a week or so before it does it again. It does it about 5% of the time, it will "miss" right at fire-up. The battery, alternator, starter are all fine.
  • poncho167poncho167 Posts: 1,178
    When you changed your plugs did you by chance drop one. If so its possible the insulator could be cracked causing spark issues. Though this is likely not the case I thought I would throw it out there.
  • luckinsluckins Posts: 63
    No, I was very careful and did everything as close to the "manual" as I could. Today, I had the same problem and it cranked fast, then very slowly, then sped up and started. Also, I remembered that sometimes the starter doesn't disengage after cranking and I get a buzzing sound right after start up that lasts about 2 seconds. So, I definitely think it might be a starter problem. But, I can't convince anyone at the dealership because when I take it in, it starts and runs to perfection. It's funny, after it gives me a really hard time for a few starts, it will start up for exactly 23 times after that perfectly. Then, the car will start to run rough and on the 24th time, it will "skip" or crank slow. Isn't that funny? :confuse:

    Well, I think it's just one of those things that has to totally break before I can take it in and say "see". I might try to work it out so that that 24th time happens on a day off when I can take it in so that they can see I'm not making it up. Problem is, I'm afraid it's just not going to start one day and I work at night. And, this last time it "skipped" it cranked really slow. But, I was playing around with it last night, so I might have worn the battery down by starting it up too much. :blush:

    Please could you tell me how many quarts of oil on an oil change. I had my oil changed for first time at an oil change place instead of dealership and had a garage floor full of oil when I woike up this morning. Did they overfill or not get filter on correctly? :confuse:
  • kisstinkisstin Posts: 3
    I have a 2005 Aveo LS with about 43,600 miles on it. A few days ago i was leaving work and when i started my car, the engine started to shake for about 30 and almost lose power, then proceded to go back to normal.

    This has been happening everytime i start my car. I've also noticed that if i don't wait for the engine to shake and sputter before i drive off, the engine will stall.

    Does anyone know what could be causing this?

    Any ideas on a fix?
  • sedmondssedmonds Posts: 1
    Not sure it's the same issue but I did have my last car doing the same thing and it was a dirty idle air control sensor. Just needed to be cleaned really good. It would start and either run fast or so slow it would die until it warmed up a little. Bad sensor.
  • timsehtimseh Posts: 24
    According to the manual, it's 3.96 Quarts (with filter).

    I'm guessing they left the washer off of the drain plug when they replaced it. I'd be on the phone screaming at the manager if I were you.
  • grace4evergrace4ever Posts: 30
    Hey thanks for your answer.
    Actually that's exactly what I did. I looked at the receipt and it said they had put in 5 qts of oil. I was a madwoman. I had to have my husband take it back because I had to work and he said the man said that the oil filter had not been tighten down enough but that the receipt was computer generated and he had only put 4 qts in. So I guess my crisis is over. I'm so afraid something will screw up my warranty that I won't take it anywhere else but the dealership from now on (and never have before). And another thing!!! - it doesn't cost any less at one of those lube places than it does at the dealership.
  • timsehtimseh Posts: 24
    This is the first car I've had where I've promised myself I'm just going to take it to the dealer for things like oil changes and routine maintenance.

    Partly because I'm lucky enough to work from a home office now, and the dealer has free wireless Internet, meaning it's not a big deal if I have to wait an hour while the oil gets changed. I can keep right on working.

    You're right about the cost, too. These days, it's actually less expensive in my neck of the woods to just get it done at the dealer.
  • poncho167poncho167 Posts: 1,178
    Your dealer is going to be your best bet for your car maintenance especially if you don't have a regular trusted mechanic. Even if you pay a little more the dealer will have a track record of your maintenance and will be more willing to address any other issue or question in the future being that you seek their service.

    Your owners manual has all the information about quantities of oil and oil filter part numbers, etc. Remember to check your oil yourself from time to time, it is very easy. Moter oil should only be checked when the engine is cold before driving to get accurate results.

    I need to replace the CO2 sensor on my car. It is the one before the catalytic converter. Could someone tell me if this would be easy to do
  • have you figured this problem out. I just started to have problems with starting my 06 aveo, have 82K miles on it. It has a hard time starting and at idling it hic cups and stalls. Also the Ignition Switch is hot to touch. Any one having this problem ?
  • smartiessmarties Posts: 3
    Got a CPU problem with my 2008 Aveo, not even 1500km on it, got the car on the 20/06/2008 and took it to GM on monday (21/07/2008) for repair. It started with some small banging in the trunk area, then one day the car stalled, got it to start again 5 min later.
    For a week after that problem, the car started but the iddle of engin speed was jumping like crazy plus the banging was still there. It the day the car was fine, it's in the morning that the problem came. The ingnition switch is hot too, the dealer do not think it has a link.
    They are going to thake the CPU from an other Aveo (hopping there is no problem with that one) replace, check in the morning if the problem come back. If all goes well, i should have it by thuesday...
  • poncho167poncho167 Posts: 1,178
    The warm/hot key thing has been reported here in the past. Is that something totally new for yours or did you just notice it?

    I think you meant you took the car back to Chevrolet because GM is located in Detroit, Michigan, U.S.A..
  • Though my Aveo hatchback is a 2007, it is a new car - one of the 2007 leftovers - that I bought in April of this year. I have gone only 1,000 miles with it, and it is stalling under dangerous circumstances. It is with a Chevrolet dealer who so far has not been able to diagnose the problem. Anybody got any ideas? The car stalled twice in the middle of a highway, and there is no way I am going to drive the car out of the dealership until the problem is diagnosed and fixed, because if the car stalls in the middle of one of the highways all over this area of Florida, there could be a resultant multiple car pileup with injuries and deaths.

    Well i still don't have my car, been gone since the 21 july now. The mecano changed all the wiering in the car (computer area). Apparentaly it is not the computers they are fine, it is a bad connection between them that is causing the trouble. The guy from GM Canada, the big tech guy, is flying to montreal today cuz they really don't know. They say maybe a relay... :cry:
    I ask to look at the hot key problem, maybe it is link to my problem. I saw it on the net that a few person had this problem with the 2007, but soo far not with the 2008. It is told that a guy had even his CD player melt. My representant from GM think that GM Canada will just give me a new car if the problem is not solved by friday (1/08/2008)
    I just want my car back, i don't like the one they lent my (cobalt LT)
  • Finally getting my car tomorrow morning..17 days later...even the tech from GM had a hard time finding the problem. It is not the relays, not the CPU, not the gas. It was the computer that was touching a metal part of the mounting bracket that was creating a jack. The computer was not getting any info in out out so that would be a reason why the car was stalling in the morning, it didn't know the heat or the octane of the fuel...(this is a really short summary). The hot key problem...well it did not do it a the garage, maybe the jack problem was doing a short??? we'll see in time..
    Soo i almost had a new car :(...but mine has only 1500 km... :shades:
  • This is a followup to my previous message. The engine of my Aveo hatchback stalled again this afternoon while I was driving it. This is the third incident - twice while driving, once while stopped at a red light. This is a car which has just a little over 1,000 miles on it. Though it is a 2007, I bought it new in April of this year (2008). There has been a recall of Aveos before, though not for this particular problem. It looks like it is time for another recall. In any event, I am about to demand that my car be replaced - but NOT with another Aveo. Though I like this car very much, like the way it handles, I no longer trust it. If the engine stalls on a highway - and you have to drive on highways in this area of Broward County, Florida - there could be a multiple car pileup with injuries and deaths.

    Unfortunately, not too many auto dealers domestic or foreign will take cars back because one has a continuing problem. This is not a common practice.
  • aveoctbaveoctb Posts: 5
    Not always true. In PA we have a lemon law that says that if a problem occurs within 12 months / 12000 miles that the dealer fails to fix after 3 or more attempts, they're obligated to either replace the vehicle with a similar vehicle, buy the vehicle back (minus some reasonable amount for wear), or pay you whatever the problem would cost you in resale value. I believe that if arbitration fails and you have to go to court, they're even obligated to pay your legal costs, though I'm not sure.

    If your state doesn't have a lemon law, check your other options as there is a federal lemon law, and you can always seek counsel regardless of specific laws if you feel you've been ripped off:
  • There is a happy ending, but an embarrassing one for me, to the problem I have encountered with engine stalling. It turns out there is nothing wrong with the car. I was allowing the key to dangle in the ignition from a keycase I use. When the dangling moved the key too quickly or distantly, that caused a change in the position of the switch so as to take the connection out of drive mode, thus cutting off the engine. A perceptive service advisor at the Chevrolet dealership where I took the car for the first three-month service, as well as diagnosis of the problem, finally figured it out. Since dumping the keycase in favor of a single key that stays straight in the ignition, there has been no problem. This goes to show you that sometimes there is a practically unimaginable cause of a mechanical problem that will remain unresolved unless every conceivable aspect is considered, including some factor that is not covered by "the book." You have to persist. I am so glad I did, since I did not really want to try to force Chevrolet to recall and replace my Aveo hatchback because, to the extent it is possible to love a machine, I have loved this car since the first day I drove it. Now I can trust it again, and I am having fun driving it - especially because of the way it handles and because of the gas mileage. For example, I filled the tank on July 16th and by August 10th when I took my next trip to a gas station for another fill-up, the tank was still at the halfway mark. Thanks to all who made suggestions as to possible cause of the stalling.

    I am having a very similar problem. Mine started when the oil pump gasket blew at 4900 miles on my 2007 Aveo. They fixed the gasket and reinstalled the timing belt incorrectly. They adjusted the timing belt and everything seemed to be okay.

    The next moring it took 3 tries to start and on the last try it seemed to sputter for a few seconds. The idle fluctuated between 500 and 1500 RPM a few times before finally settling at 1500 RPM (high idle). It ran fine after this and I took it to the dealer. They said it had dirty injectors. This surprised me since I mainly use Chevron gas, no cheap gas and it only had 5000 miles total. They cleaned the injectors and gave it back to me. It ran fine and started fine. The next morning it happened again. I left it with them for 4 days and they could not replicate the problem. It has happened 6 times now. in 2 months. It happens about every 2 weeks. Once it starts it has no problems. I can turn it off and start it again without any problems The dealer says they can't fix it because they can't find it.

    You said,
    "It's funny, after it gives me a really hard time for a few starts, it will start up for exactly 23 times after that perfectly. Then, the car will start to run rough and on the 24th time, it will "skip" or crank slow. Isn't that funny?"

    What is the time frame that you are seeing between the 24 times. Do you start it 24 times in row or is this over a few days of driving?

    Have you figured anything out? How many miles does your Aveo have and what year is it?

  • flaaveoflaaveo Posts: 161
    I know that you SHOULD pressure flush most radiators every 2 years, and refill with new coolant, of course. The chemicals in the coolant 'break down' around the 2 year mark, so I have always been told. My questions are.

    (1) Is it still the 2 year mark for flushing the coolant system for the Aveo, or does it have that long lasting coolant in it, that lasts like for 5 years?

    (2) OR would adding one of those pint bottles of Prestone 'Anti Rust/Water Pump Lubricant' additive, be just as good? I drain out like 1 pint of coolant, so it doesn't overflow, and just pour it in the radiator. It is suppose to replace the 'protective chemicals' in the coolant and help lubricate the water pump and make it last longer.

    I did use it in one of my Ford Rangers, at the 3 year mark, and the radiator never had any rust develop. I drive so little...I have a 2006 Aveo Hatchback, and it only has 9,700 miles. Does that change the time period to change the coolant and maybe make this an option?

    Should I spend all that money on an expensive professional flushing? OR spend just $6.00 on a bottle of that radiator coolant additive? Any opinions? I take very good care of my little car. But this is the first 'non warranty' maintenance thing I have had to think about doing, other than oil and filter changes of course.
  • poncho167poncho167 Posts: 1,178
    Flush every two years unless it has the 5-years Dexicool. Flushing services usually do it for $40-70. It is worth the piece of mind.

    Adding additives doesn't preserve the useful life of the antifreeze.
  • flaaveoflaaveo Posts: 161
    Hey. Thanks for the reply. Do you know if our Aveos have that Dexicool in them? That is the long lasting coolant I was talking about. Isn't it orange or red? I know mine is the plain old its the plain old coolant?? Or do they come with that Dexicool?
