Bought 6/17/2023 with 81k miles (1.4L turbo). By ~7/1/2023 it ran rough and hesitated after refueling. Firestone (Brick, NJ, 7/5/2023 at 82,090 miles) said radiator leaking; keep topping off; noted open Chevy “special coverage” bulletin. Over ~2 years kept adding coolant (high consumption). Rough running worsened.

On 11/27/2025, at ~60 mph uphill on the Garden State Parkway, engine shook, dash showed “Engine Power Reduced/Service StabiliTrak” (CEL blinking), lost acceleration. Pulled over and towed; white smoke at tailpipe. Tow driver suspected coolant ingestion/head-gasket failure needing engine replacement. Odometer: 124,180. Traded in on 11/29/2025 at Automotive Avenues (Wall, NJ); no manufacturer/police/insurance inspection.
