When problems show up
Only 17 complaints listed a mileage: too few to say when problems show up.
Questions to ask the seller
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Do the brakes feel even, with no ABS or brake warning light? When were the pads and brake fluid last done?

How serious. Out of all 27 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 3K to 38K miles (6K to 62K km) on the car (17 of all 27 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.
Fixes owners look up most.

Every Cadillac XT5 year. 2018 is highlighted. Lower is better.
Newest year first. Red = worse than average, gray = about average, too new (2023+: a partial score, marked “partial”) or too few complaints to score. #1, #2… = that year's YouTube rank among the 6 Cadillac XT5 years with enough videos (#1 = the year owners and reviewers talk about most positively). It is not a reliability rank.
