Vehicles affected by this service bulletin:

  • 2009 Acura TSX
  • 2010 Acura TSX
  • 2011 Acura TSX

The problem: Owners may experience low engine-oil levels due to deposits forming on the oil control rings, causing them to stick in place. If this happens, engine oil lubricating the cylinder walls runs through the ring gaps and into the combustion chambers where it's burned and consumed, thus lowering engine-oil levels. Over time, the engine will sustain cylinder wall damage.

Corrective action: Dealers will run an oil consumption test to confirm the condition exists. If confirmed, dealers will replace all the engine's pistons and piston rings. If the cylinder walls have deep scratches, dealers will replace the engine block, as well.

Warranty info: Repairs will be covered under an extended warranty (eight years or 125,000 miles from the original vehicle in-service date, whichever comes first).

What owners should do: Call your local dealer with your vehicle's identification number to determine if it's involved in this service bulletin. You can also call Acura at 800-382-2238. Reference TSB No. 13-006.
