I took our 2018 QX80 in for a routine oil change and the service writer, Anna Graff, noticed it was riding a bit low in the rear and the air compressor was louder than it should have been. I didn’t notice it, but she was right. Turned out to be a bad compressor valve and it was still covered by the bumper-to-bumper warranty. They fixed it while I waited, changed the oil, rotated the tires, did an inspection and washed it too. $143.18 total. Great service as always.
