When problems show up
Most problems on this year showed up between 2,000 and 30,000 miles (3,200–48,000 km) (the middle half of the 28 complaints, of all 42 filed so far, that listed a mileage).
- At 60K, 100K and 150K miles (97K, 161K and 241K km) Past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most.
This is when owners who had a problem reported it, not the odds that one car will have it.
Questions to ask the seller
- Were recalls 14V355000 (electrical), 10V240000 (electrical) and 08V441000 (electrical) done? It has 4 recalls in all. Ask for the dealer printout, or check the VIN.
- Does it accelerate and hold speed smoothly, with no surging or stalling?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Cadillac sent dealers 724 repair notes for this car. Was this one done: “Pontiac/saturn/buick/gmc/chevrolet/cadillac/hummer: vehicle start and stalls after theft…”?

How serious. Out of all 42 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 2K to 29K miles (3K to 48K km) on the car (28 of all 42 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.
In owners' words
Vehicle will not start. I have had the car since the end of november 2005 and on two occasions the car was dead. I did not buy the car to run everyday or in bad weather.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
