My 2018 Malibu LT is sitting at 114,850 hahaa. Bought it for $11k in March of 2020. It had 42k already on it from being a Hertz rental. Relatively risky purchase since it had a small fender bender in 2019, but multiple inspections and test drives had me convinced it was still solid.
Similar experience to other high mileage gen 9s. Engine has been magnificent. Oil and oil filter changes between 5 and 7k miles apart; spark plugs and coil packs once so far at 90k miles. Transmission is rather laggy to begin with, but ive also noticed shifting 3rd into 4th can be rough (rpms briefly rise before it engages 4th gear). This issue is seen mostly in first few miles of a drive or sometimes when under hard acceleration. Will be getting this checked out by a mechanic if it gets any worse. Transmission fluid changes every 30k miles so far using ac delco dexron-vi.
Recalls and other common issues have been fixed at dealership: Pedal sensor, transmission fluid pan bolts, shift to park.
Same battery from when i bought her. New set of Continental PureContact LS all seasons, recently rotated and then got a nail puncture same day. Plugged and sealed; probably shouldve patched as well, but its holding air and performing normally. OEM pads and rotors at 100k. New oem windshield wipers.
Needs: coolant flush, brake fluid change, battery, trans cooler lines (just learned this). If anyone has additional preventative maintenance items i havent mentioned please speak up. At 140k i plan to do suspension work including front strut assembly, rear shocks, rear sway bar (want stiffer than oem), front and rear end links, front and rear hub bearing assembly, cv axles, and finally rear knuckles (knocking has been heard since 70k, but only hear it in hotter months).
Thank you for letting me share my Bu with you.
