Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Service Bulletin - Due to high demand for repairs under this warranty extension, pistons and rings required to complete this repair are currently backordered. Acura has provided this service bulletin (19-052) as a mechanism to cover clients that were not able to have repairs completed during the initial 6-month eligibility period on service bulletin (19-006).
full bulletin at NHTSA ↗Dealer Message - On January 16, 2019, Acura announced a warranty extension for certain 2009-14 Acura vehicles equipped with a 3.7L V6 engine to address client concerns related to excessive oil consumption. Acura extended the powertrain warranty coverage to address engine issues related to excessive oil consumption from the original 6 years/70,000 miles to 8 years/125,000 miles, whichever comes first. In addition, all vehicles were provided a grace period until August 31, 2019 and were covered regardless of time in service or mileage.

These deposits restrict the ring's ability to scrape and return oil from the cylinder wall to the crankcase, which can result in excessive engine oil consumption that may exceed client expectations.

I received notification of excessive oil consumption affecting my vehicle from Acura (2013 mdx) I took the car as instructed to bridgewater Acura and they performed an oil consumption test. According to the manufacturer the car had to consume at least 1 quart of oil per 1,000 miles. The dealer stated that my car showed that my car consumed 1 quart at the first 1,000 miles, and 1/2 quart each time…
I changed the oil in my car with synthetic 4k miles ago. About 1k miles ago I started getting an error that said low oil level. I went back into the lube shop to see what was going on, they said there was no leakage or issues there but there was hardly any oil in my car and that it was probably burning oil. I searched for issues with my 2013 MDX burning oil and an issue in 2019 with clogged oil…
It is having oil consumption issues .
I was driving approximately 20 MPH when the engine completely shut down without warning. The car was still in drive, the ignition on, when it suddenly shut down and decelerated. I managed to make a right turn onto my street, although the power steering was not functioning. I put the car in park and restarted it with no problem. I did have a small wallet (dimensions were @ 4in by 5in, weight…
