Questions to ask the seller
- Were recalls 26V329000 (airbags), 18V595000 (seats) and 15V358000 (brakes) done? Ask for the dealer printout, or check the VIN.
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Does it accelerate and hold speed smoothly, with no surging or stalling?
- Cadillac sent dealers 1781 repair notes for this car. Was this one done: “OnStar Module Battery Drain”?
From this year's own recalls, top problems, top repair bills and Cadillac's repair notes. Recall repairs are free at any dealer.
How serious. Out of all 11 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 9K to 31K miles (14K to 51K km) on the car (8 of all 11 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.

- Airbags · recall issued 2026 New: most likely still open
The front-driver air bag inflator may rupture during deployment.

The flexible heating mats in the front seats may be damaged over time, resulting in the seat heaters producing excessive heat.

The affected vehicles have a bracket between the brake pedal assembly and the rod that actuates the brakes that may fracture during normal brake pedal operation.
Recall repairs are free at any dealer. A recall only matters if it's still open on that exact car, so check its VIN.
