Honda's Excessive Oil Consumption Problems

Honda Excessive Oil Consumption
Honda's V6 engines are burning through oil like it's going out of style

One of the top complaints about the latest generation of Honda vehicles is how the V6 engines burn through an excessive amounts of oil.

Mechanics did their best to place the blame on the owner's driving and maintenance habits, but it was clear through thousands of complaints that this was an emerging problem trend. A judge agreed.

Oil Consumption Class Action Lawsuit

A lawsuit claimed that Honda produced 1,593,755 vehicles that excessively burn oil and need frequent spark plug changes, and hid it from consumers:

“A systematic design defect that enables oil to enter into the engine's combustion chamber. This leads to premature spark plug degredation and engine malfunction.”

Honda denied the allegation, despite issuing a Technical Service Bulletin (TSB #11-033) in July of 2011 that quietly acknowledged the problem.

The TSB states that "the VCM (variable cylinder management) may be repeatedly switching on and off during light throttle operation, at cruising speeds, on flat roads." Essentially, the engine is working much harder than it has to in normal driving conditions.

In fact, if your commute doesn't consist of climbing through the Rockies, you're probably going to see more oil consumption than normal.

The Settlement

On October 22, 2013, Honda America agreed to settle the class-action suit. As part of the settlement, Honda extended the powertrain warranty on these models for eight yers from the time of purchase or lease with no mileage limits. Honda also offered to reimburse customers who had to pay out-of-pocket expenses for related repairs such as spark plugs, pistons or even entirely new engines (with limitations).

The settlement was reached after U.S. District Judge Susan Illston declined Honda's motion to force arbitration on the case in Oct. 2012. The judge found that Honda was a third-party non-signatory to a contract and therefore may not compel arbitration under the terms of the contract.

The settlement covers the following vehicles equipped with six-cylinder engines (U.S. models only):

  • 2008-12 Accord
  • 2008-13 Odyssey
  • 2009-13 Pilot
  • 2010-11 Accord Crosstour
  • 2012 Crosstour
  • That's a great start, but we've also received complaints from owners of the following vehicles who should get the same benefits: 2009–10 Pilot (All), 2011 Pilot 2WD (Some), 2011 Pilot 4WD (Some). Have another vehicle you think should be covered?

    To verify your vehicle is covered, you can call Honda at (800) 999-1009 and provide them with your VIN. You can also bring your car into a certified Honda mechanic.

    The Complaints Keep Rolling In

    Excessive oil consumption in Honda's is one of the top complaints submitted to In fact, the problem was listed as the worst problem in the top problem trends of 2012.

    The majority of complaints say that they were told from Honda and dealership mechanics that it was normal for a powertrain to burn a quart of oil every 1,000 miles. The class-action suit claims Honda refused to honor its warranties and instead told people to check their oil every time they stop for gas. Yep, "normal".

    “When I get an oil change, I would need to add at least 2 quarts of oil before the next oil change is do. It started off with adding oil the very next month after a new oil change! That is so ridiculous.” Rosaline E. of Raleigh, NC told “The only way I would know that I needed more oil was there would be a burning smell coming from the car and a knocking noise. My oil light indicator would never light up-which is another malfunction.”
