Wow. Your car is holding up well for the mileage and age. I assume that you have AWD hence the rear differential, which always requires a bit more drive-train maintenance like clutches/gears.Update to my previous post:
Just hit 195,000 on the 2010 Lacrosse CXL. She seems a little more temperamental now but still running strong. I religiously change the oil every 3,000 miles. I have not ever done a transmission fluid change which I've been debating recently.
Things that failed on me:
1. Both front and back catalytic converters twice.
2. Rear differential went bad around 150k. (Clutches inside I think?)
3. The rear sunshade is stuck in the up position. I can get it to go down but every time I put the car in reverse it goes up.
4. Replaced the coolant overflow/reservoir due to a small pinhole leaking in it.
5. Currently on my third battery.
All in all not terrible when considering I'm going to hit 200k in the next couple weeks. I think I may invest some money into the car soon and update a couple parts that are due. (I'm still on my original water pump). If it makes it to 250,000 I'll be content.
