Condition

Some 2011 model year Chevrolet Equinox and GMC Terrain vehicles, equipped with a 2.4L engine, may exhibit excessive engine oil consumption (less than 2,000 miles per quart of engine oil), due to piston ring wear. If this condition is present, the oil can light may illuminate on the instrument panel or the following message may appear in the Driver Information Center: “Oil Pressure Low – Stop Engine”.

 

Special Coverage Adjustment

This special coverage covers the condition described above for a period of 7 years and 6 months or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Dealers are to replace the 4 piston assemblies. The repairs will be made at no charge to the customer. For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after July 21, 2015, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to July 21, 2015, must be submitted to the Service Contract provider.

 

Vehicles Involved

All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties section in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

Service Procedure

Customers will be notified of the Special Policy by General Motors (see copy of owner letter included with this bulletin).

Note: This special policy covers repairs after the original powertrain warranty has expired. For vehicles still covered under the original powertrain warranty, the labor code operations should be used from bulletin 13-06-01-003.

Note: Technicians should perform an oil consumption test to determine if the pistons and rings must be replaced. Follow the latest version of Corporate Bulletin Number 01-06-01-011 to perform an oil consumption test. Before starting the oil consumption test, verify the ECM has latest TIS2web calibrations to adjust the engine oil life monitor to a maximum of 7,500 miles (12,070 km) — Refer to the latest version of Customer Satisfaction Bulletin number 12312.

Determine the rate of oil consumption.

  • If the oil consumption test indicates that the rate of consumption is less than 1 quart (0.946L) of oil every 2,000 miles (3,200 km), note the oil consumption rate and the date that the ECM was reprogrammed. No further action is required.
  • If the oil consumption test indicates that the rate of consumption is greater than 1 quart (0.946 L) of oil every 2,000 miles (3,200 km), note the oil consumption rate, the date that the ECM was reprogrammed and replace the pistons and rings.

Note: The repair is to replace the pistons and rings. In some cases the bore surface may not have a uniform look to the finish (zebra stripes) as shown in Technical Service Bulletin 13-06-01-003. As a result, some technicians may question whether the engine should be repaired or replaced. After careful evaluation, GM Powertrain has determined that the new pistons and rings will perform correctly in bores that have this appearance so engine replacement should not be necessary. The cylinder bores do not need any machine or honing work performed on them. Refer to Technical Service Bulletin 13-06-01-003 for more information.

 

Piston and Ring Replacement Procedure

Piston and Rings

 

Note: Review the following service procedures and technical bulletin in SI:

  1. Remove the engine from the vehicle.
  2. Remove the pistons from the engine.
  3. Remove the pistons from the connecting rods.
  4. Discard the pistons and piston rings.
  5. Install the new piston rings onto the new pistons.
  6. Install the new pistons onto the connecting rods.
  7. Assemble the engine.
  8. Install the engine into the vehicle.

Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer by August 31, 2016, unless otherwise specified by state law. If this is not convenient for the customer, they may mail the completed Customer Reimbursement Request Form and all required documents to the GM Customer Assistance Center.

Important: GM requires dealers to approve or deny a reimbursement request within 30 days of receipt. If a reimbursement request is approved, the dealer should immediately issue a check to the customer and submit an appropriate warranty transaction for the incurred expense. If a reimbursement request is denied, the dealer MUST provide the customer with a clear and concise explanation, in writing, as to why the request was denied. The bottom portion of the Customer Reimbursement Request Form may be used for this purpose.

The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

35 thoughts on “Excessive Engine Oil Consumption – 2011 Chevrolet Equinox & GMC Terrain

  1. Bought our 2011 Chevy Equinox last May from a dealership. I was never informed of the bulletin not verbally nor did we get a letter. Now I wss told to do an oil consu test and they would try to work with me. No such luck . I don’t know why they told me to do the test. I knew it was using too much oil. Dealer wants $3800 for the repair. What can I say. So disappointed in GM !

  2. I’m confused, I have the 2011 Terrain, 89k miles. Its almost August 2018, will my vehicle be covered? What do they mean by “7 years, 6 months from when the car was first put in service”? Going to the dealer tomorrow.

  3. I have been telling gm about the oil consumption since 2011 and said it was normal. Now i have 196000 km on my terrain and was never notified that there was a problem and now they have TSB 15285C out now i have to see if they will cover my suv

  4. I just had the oil consumption test and was approved my car was fixed per the recall procedures and within an hour of me leaving the check engine light is back on. I went starlight back and they said it’s the camshaft and the reCall doesn’t cover that? How is it now a new problem right after being fixed? If the oil consumption caused damage to the can shaft shouldn’t that be covered?
    Should I get rid of my 2011 GMC Terrain? Is it going to be one thing after Another now

  5. I purchased a 2011 Equinox back in March 2016. Since then, I’ve completed oil consumption test at least 2 times and the dealer reports there is nothing wrong, however, I must change the oil or the car shakes, rattles and knocks. I’ve had the catalytic converter fixed within the first six months. I’ve had a gas smell in my car and recently because I’ve exceeded 120, 000 miles they said I don’t have a warranty and had to pay out of pocket. Now the car alarm goes off in the middle of the night for no reason. This car is costly and as a single mother, I’m not financially equipped to put all this money into a car every other month. Now there is a recall that I was unaware of on the electrical system and was not notified at all. A lot of your responses say refer to the dealer but they are not holding up to there end of the bargain refusing service or indicating that there is no problem. I need answers now!!!!

  6. I own a 2011 Equinox and it is doing the same problem with oil consumption. It is now making a loud rattle noise. It has 137,000 miles on it. Will the dealership fix the piston rings and do an oil consumption test or will have to pay for the repairs myself and probably be out a couple grand.

  7. Does a special coverage adjustment require you to show proof of routine maintenance on the vehicle, similar to what you would have to do under your normal powertrain warranty?

  8. So I have a 2011 equinox 2.4 that went through the consumption test and had the “ring job.” Unfortunately it developed oil leak around edge of oil pan (doing a number on my garage floor). I brought it back, they “fixed it” and now 6 months later it is leaking again. Will bring it back, but is this a common issue with this repair?

  9. My 2011 equinox has 85000 miles and has always burned excessive oil, now it’s leaking oil and I was told it’s the front crankshaft seal. Would this issue cause the seal to break? Will chevy cover the repair?

  10. My 2011 Equinox is apparently not one of the ones in the special coverage adjustment. I have been concerned for the past 6-8 months about oil consumption but have no obvious leak or warning light. Am I able to have my vehicle tested even though I’m not supposedly included?

    1. did you ever get this covered??

      My car just broke down three days ago to the same issue… New engine costs $6400

      Please let me know if you got this resolved!

  11. Our dealership told us we could not get a rental covered by them while this issue was getting fixed. Why is that?

  12. What if I have a 2012 Equinox with 65k miles and it was manufactured 8/11? Oil consumption is around a quart every 1000 miles. No low oil light or message but check engine light comes on. Warranty or not?

    1. I have a 2011 Equinox which I purchased from my late mother’s estate in 2016. Recently, my engine blew, and I was told that it was low on oil. I put many miles on my car and am good about changing oil. The engine light recently came on and the day the engine blew I had an appointment to have the oil changed. I never received a recall, nor did my mother in my recollection. Am I out of luck (and several $k)?

  13. I have a 2011 Chevy Equinox with this issue. I bought it used with 80,000 miles on it. Brought it back to the dealership 3 different times (under warranty) due to the oil consumption. They blamed it on an oil leak each time. It started small and now uses 1qt every 500 miles. Unfortunately, by the time that they finally diagnosed it with this issue it was over the 120,000 mile mark and basically told me too bad. Being a single mother of 2 and this being my only mode of transportation I am beyond frustrated with GM. Will NOT make this mistake again. Even the service writer at the dealership told me it wasn’t worth the money to repair it out of pocket.

  14. I received this recall and have been taking my 2011 GMC Terrain to the local GMC dealership for the last 2 months about 6000 miles and have my oil changed twice as they make me bring it in every 1000 miles to check for oil consumption and it’s always between 1/2 quart to 3 quarts low and they keep telling me there is nothing wrong and it’s not using enough oil to qualify however I should keep bringing it in. Is there anything else I can do?

  15. I took my 2011 GMC Terrain to an auto shop as the check engine light was on. I was told the issue is due to my timing chains failing because my oil consumption is higher than normal. I informed them I regularly change my oil but they said it was typical for these models to have this issue and quoted me a ridiculous price but then I learned about this special coverage. Would my issue be covered under this special coverage even though the oil lamp light is not on?

  16. My Equinox is having this same oil consumption issue. GM said they are not fixing because the owner before me had it fixed and now they don’t believe they should do again.

  17. Hello: My 2011 Chevrolet Equinox LTZ had the above issue, was repaired using the procedure above, and still continues to use excessive amounts of oil in between oil changes (about 1.5-2 qts per 3000 miles extra). In addition, I am continually smelling burning oil, so there is an oil leak somewhere. What does GM recommend is my next course of action? Please advise immediately as this is my only means of transportation.
