Hmm. I'm about to reach 60000 on the car (2011). I skimmed through the ten past pages. It sounds like it's going to be a hit or miss with engine trouble, then? Also should be checking oil more regularly from now on. Maybe I should sell this car before it gets to 100000.
When I parted ways with my 2011 GLS it had 170,000 miles on it. I had driven it fairly hard but took care of it maintenance wise. The oil consumption had started being a concern the past 6 to 8 months. I could tell that it consumed more oil during the times I would be under hard acceleration (tell, tell sign was the smoke from the exhaust each time I would accelerate hard (not black smoke, but blue-gray)). Up until the trip I would add about 2 quarts between oil changes (5000 miles). However, during the trip (prior, during, and after), 3 quarts was really the signal to either get work done on it or get a new car.
I choose the latter option. Really wanted a new car and I had just upgraded my son's car from a 2011 to the 2015 Limited. I was really loving his car so that also made my choice way easier. With some work, I'm sure the 2011 would have lasted well beyond 250K. Interior still looked fairly new, everything worked, but the issues were, paint job showed signs of age and the oil consumption issue.
Outside of normal wear and tear items as far as maintenance (like tires, brakes, rotors, plugs, coils, filters, belts, etc) I did replace the left front axle (162,898), clock spring (129,962), steering coupler (128,997), inhibitor switch (123,930), starter (67,563), and EVAP Canister (2,504 (split at seam, manufacture fault)).
Hope this mx track record helps you and everyone else out.
