    Too much BS going on ! My 2008 Impala will suck the oil pan dry long before its due for a oil change. Same story taking car in for 20 min sit & wait, to check oil every 500 miles. The wife drives it to work 80 expressway miles round trip a day, plus her other shopping so almost 100 miles a day. Its sitting at the dealer day 2 now for another check engine light on. I found a Chevrolet Customer Relations Department # 800-222-1020 the lady was nice and said they will call the dealer today she even gave me a case # a phone# ext# as I told her, I will make signs of my car drinking out the hood with a baby bottle of oil, put them on the both sides front & rear and park it in front of every chevy dealer in town, I will make a unhappy chevy owner picket sign and have some of the internet emails to show interrest people thinking of buying a chevy! with chevy saying using 1 quart of oil every 1000 or 2000 miles is OK ! It dont leak a drop of oil, its not in the cooling system, so its burning it ! even if no sign of smoke !

    Good afternoon oileatingchevy,

    I'm happy to hear you've been in touch with our Customer Assistance Center - do you have a case number (71-**********)? I would be happy to check in on it to see if there are any updates for you.

    It is correct that the accepted rate of oil consumption in passenger vehicles is 0.946 liter (1 qt) in 3200 km (2000 mi). All engines require oil to lubricate and protect the load bearing and internal moving parts from wear including cylinder walls, pistons and piston rings. When a piston moves down its cylinder, a thin film of oil is left on the cylinder wall. During the combustion process, part of this oil layer is consumed. As a result, varying rates of oil consumption are accepted as normal in all engines.

    Other factors can affect oil consumption, including continuous driving at high speeds/high RPMs may increase oil consumption (because this may not always be an everyday occurrence, it is hard to determine exactly how much the oil economy will be affected) and engine wear (piston scuffing, excessive piston-to-wall clearance, tapered or out of round cylinders, worn, damaged or improperly installed valve guides, seals and piston rings will all cause an increase in oil consumption).

    Again, I'm happy to check into your case if you wanted to get that number to me!

    Regards,
    Sarah

  • Like I told Gm Customer Service , I made signs w/ pictures of my car drinking oil, a picket sign that said UNHAPPY CHEVY OWNER ! I parked it in front of 4 Chevy dealer lots, only took 5 mins for them to come out and talk to me. They were all nice to me except one , who called the cops on me, but its not against the law to picket, just keep moving, be nice, dont block people or cars ! He later came around to my way of thinking and said he will make some phone calls and try to help. I gave them all the case # names ect. only took 15 - 20 mins at each place. One of the Bigger Chevy dealers said they already fixed a car with the same problem before, and would gladly check into it, make some calls and call him back Monday morning, ended up taking the car there at 11:00 he gave the wife a 2012 loaner car. Car was ready next morning they did the heads, and also found the intake manifold gasket was leaking but not on the ground, they found it with mirrors. We bought 3 new chevys from our small town Chevy dealer in 2009, where we buy our next car ?
  • I want to buy a new 2014 Impala as soon as they come out. New one really great looking but I don't trust that 3.6 engine. After reading about it in the Cadillac and its been out a few years and do they try to change for the better or do they just keep building the way it is. I have a 2009 Impala LTZ with the 3.9 and its a great car. Change oil 3-4000 and dealer always checks before change and its always full. Thats bs that a quart to 700-900 is normal. I had over 65 cars in my life time and the most oil I had one burn was a quart to 1200-1500. I would like hear from someone who has 2012 with 3.6 or other GM with that engine. I've read most of the Cadillac complaints. I can't believe GM would keep building that bad of engine and not improve it and not take care of the customers who have already purchased them.

    i have also have had the same problem with my ss impala and after about a year of going threw the same thing with the dealer i got hooked up with the excutive dept.in detroit they did agree that there was a issue and just last week put new pistons and rings in my engine.I have not put many miles on the car yet but it has a lot more power.....time will tell....good luck

    I also have the 3.9 V6 in a 2007 Uplander. It has 66k miles and does not use any oil between oil changes. I use Mobil1 and change the oil every 3k miles. A quart or two every 1k or 2k miles is ridiculous for a new car, especially a luxury car like a Cadillac. I agree with you, stay away from the 3.6. It's a poorly designed and engineered engine. Good luck with your next purchase.

    We bought a 2008 Chevy Impala last spring from a dealership. The car only had about 23,000 miles, excellent condition inside and out. We noticed when checking the oil it was barely reading on the stick,so called dealership and they did not say much about it and changed the oil again. Then, it was very low again on stick and first thought " It's using oil because it was not leaking oil . Then, the dealership sent us to the Chevy dealership and they replaced a seal ,said it was a small leak . Then, it is still reading about 1 notch on stick and we are upset about this whole situation. Should this be considered a lemon car and pursue under the lemon law act ? It is still under warranty but we do not want this car because we know it will be nothing but continued problems . Please give us any feedback on this.

    My 2008 went thru that for about 6+ months, with trips to the dealership every 500 miles for a consumption test (they checked the oil). Finally after another idiot light showed up (check engine) they kept it for a day checking it forward and backward. They found at least 3 "small" leaks, which took them 3 days to fix. It was all done under warranty but it was the idea that they kept telling me there was nothing wrong before they had to chase down the check engine light. Even told me the loss of oil was within toleration by the factory. So far their fixes seem to have done the trick. I even get better gas mileage if my last road trip is any indication. I've entered several posts here related to the on-going issue from months past. Search my id and you should get a feel for what I went thru. Keep at them and don't take their glib excuses; demand better service than that! I love the car but was very very disappointed in how they handled my questions and complaints. Good luck!

    have a 2006 cts with same engine.have 96,000 on it,but has been using 1 qt every 1000 miles,dealer and gm swear this is normal.got new oil 4,000 miles ago. checked crank case oil level doesn't register, both dealer and gm want me to pay 90.00 for oil change and 236.00 for oil consumption test. gm knows engine loses oil 53 pages of cts complaints on edmunds,com.
    have driven chevies for years-my opinion,buy base impala-no frills-drive it until it falls apart.
    had a lumina that had 150,000 miles on it.all did was change air filter,oil filters,rotate tires and put on tires when needed.would still have car if woman had not run a stop sign and totaled car.
    for a fun ride get a stang,fast and friendly
    gm got public money and will now sell their high end cars to welfare queens, take'm back when they don;t pay and than selle;m again
  • :lemon: I hope not . I have a 2008 impala lt with 45,000 miles have the same problem. No leaks what so ever. Added 2 quarts last week and a 1/2 pint yesterday. What the hell. Dealer next week thanx to my 5 day drill. Keep you guys posted when they check it out.

  • I love my 2007 Impala, so I'm totally disappointed. My "Low Oil" light came on. The dealer told me I should never be low on oil unless I have a leak or it's burning too much. I haven't seen any spots on my driveway, but I have smelled a faint burnt oil smell. I got an oil change last week and I'm already seeing less on the dipstick. I'm taking it in for service on Friday. After reading these posts, I'm afraid it may get costly! I just hope they find out what's wrong the first time.
  • Good afternoon lovemyimpala,

    We hope that the service visit on Friday goes well; if you want for us to check into the situation further please email us at socialmedia@gm.com (include your name and Edmunds username, phone and address, the last 8 digits of your VIN and mileage, and the name of your dealership).

    Any update. Make sure you keep pestering them. GM fed me a line of bull, until my car was out of warranty. I wish there was a simple fix for this.
  • Hi Sarah, this is just an update on my 2008 Impala. Well the same issue is going on. This is the 3rd time that my dipstick has no oil. The car has only 49831 miles on it and recently did an oil change at 48170 miles approx. My wife drove it down to NYC from Felts Mills NY which is only 340 miles apporx. she had to add 2.5 quarts of oil and I believe that is excessive oil to add. Also she had to add coolant almost a gallon. This issue needs to be fixed. The complaint number I have is 71-1105851756 and the dealership all they can tell me is that oil change is needed and thats not the problem. I love the vehicle but this issue needs to be fixed. If you can help me I will greatly appreciate it. Im deployed now so any info please feel free to email me at peterpoo4eva@yahoo.com thank you. :mad:

    Hello impalapete76,

    I just checked in on that case and see that it is currently with your District Specialist, who is doing their best to check into this further. I will make your agent aware of your post and concerns and do my best to keep an eye on it. As your current agent is with a more specialized group within customer service, I will not be able to take the case over or anything like that, but I can keep you updated.

    Thank you for your service to our country!

  • I have a 2009 Impala with 54,000 miles and am exhibiting the same loss of oil described above. I have been using full synthetic since when I purchased the car at 10,000 miles. In the last six months, I have twice been alerted that my oil is low and to stop the car. Each time, the oil was 2.5 quarts low... I am going to follow up on this with the dealer and will provide an update on what I find out.

    Is the engine in your vehicle a 3500 or 3900 V6? Or is it the V8?
  • Well obviously since my wife is taking care of the car because Im deployed. Here is a update. Once again DAMN OIL CHANGE, and they having my wife coming every thousand miles, the funny thing is my warrenty ends in febuary. So I told her to take the car at the end of this month that they can check it. Until then I wont know. I will keep updateing when I get the word. I do feel you guys pain. But since I was a GM Tech back in the day I am familiar with GM vehicles so worst comes to worst Ill do the job myself since the dealer is giving me the run around. :mad:
