Suspected causes are piston/ring design and PCV behavior; GM handled cases with consumption tests (threshold: 1 qt per 2,000 mi) and repairs under powertrain warranty. Check the dipstick monthly; running low is what kills these engines and their turbos. Typical cost: Free under 5-yr/60k powertrain warranty if it fails the consumption test; $2,500-$4,500 for pistons/rings out of warranty. ### Turbocharger failure (often oil-starvation related) (major) Turbo failures on the 1.5T, whining/grinding, loss of power, blue exhaust smoke, are commonly a downstream casualty of the oil consumption problem or oil-feed line coking. Oil pushed past turbo seals also mimics a failed turbo. Keep oil full and fresh; replace the feed line with the turbo. Typical cost: $1,500-$2,800 parts and labor. ### Brake vacuum pump failure ("Service Brake Assist" message) (major) The 1.5T uses a cam-driven mechanical vacuum pump for brake assist. It wears or seizes, triggering a hard brake pedal with a "Service Brake Assist" message, and in the worst cases the pump's drive gear breaks and sheds debris into the cylinder head. Well documented across 2018-2022; replace promptly at the first warning. Typical cost: $400-$900 (pump); far more if debris damages the head. ### "Shift to Park" message when already in Park (minor) A GM-wide defect this generation shares: a worn microswitch/contact in the shifter assembly makes the car think it isn't in Park, so it won't shut off and warns "Shift to Park." Jiggling the shifter is the classic workaround; the fix is a shifter assembly or switch replacement, addressed by GM TSBs and litigation on related models. Typical cost: $100-$450. ### Transmission shudder and harsh low-speed shifts (moderate) Owners report torque-converter shudder (a highway-speed vibration like driving over rumble strips) and clunky 1-2 shifts on the 6-speed, addressed by GM TSBs calling for a fluid flush with updated Mobil 1 LV ATF HP and software; the 9-speed on 2.0T cars draws fewer but similar shift-quality complaints. Rarely a hardware failure when caught early. Typical cost: $200-$400 (fluid exchange per TSB); $1,500+ (torque converter). ### Diesel emissions/DEF system faults (1.6L) (moderate) The rare 1.6L diesel is mechanically stout but its emissions plumbing, NOx sensors, DEF heater/injector, EGR, generates check-engine lights and occasional reduced-speed countdowns. Parts are dealer-only and no longer common stock, so budget accordingly. Typical cost: $300-$1,200 depending on component.

Across all years the key points owners look up are simple: dexos1-licensed oil (5W-30 on the older engines, 0W-20 on the turbos), Group 47/48 batteries (AGM once stop/start arrived in 2018), 140 lb-ft lug torque, and a CR2032 fob battery until the 2025 redesign switched to CR2450. Note the bolt pattern changes by generation: 5x120 (2010-2017) to 5x115 (2018 on).
