Questions to ask the seller
- Were recalls 23V172000 (transmission & drivetrain) and 23V042000 (transmission & drivetrain) done? Ask for the dealer printout, or check the VIN.
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Chevy sent dealers 576 repair notes for this car. Was this one done: “This technical bulletin provides repair information to correct a customer concern of hearing…”?

How serious. Out of all 44 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 6K to 48K miles (10K to 77K km) on the car (15 of all 44 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
