Alternator bearing noises. At that mileage if it hasn't been changed yet it will need to be done. You can get rebuilt but it has to be a BOSCH voltage regulator.
Check for corrosion at the modules under the drivers seat.
Look to see if anything was ever spilled on the seats... could cause SRS issues down the road
Front lower control arms, links and bushings.
Oil leaks from the camshaft plugs/pcv at the rear of the cylinder heads.
The sam module might take a crap eventually. Make sure the brake fluid has been changed it not do it, very important.
By 2010 the balance shaft issue was sorted out I would still check for codes... The codes that would be stored would be P1200 and P1208 and misfires.
Overall solid cars. I'm sure I am forgetting something else in the rear suspension
