Which XT6 is it?

EPA figures for each version of the 2025 Cadillac XT6. Use them to confirm you are looking at the version that was advertised, and as a yardstick on the test drive.

VersionDriveEPA rating
2.0L 4-cylAWD, FWD23 mpg
3.6L 6-cylAWD, FWD20–21 mpg
  • The 2025 Cadillac XT6 was sold in two versions. Confirm which one this is from the window sticker, the engine cover, or the VIN report before you compare prices.
  • Reset the trip computer at the start of the drive. A XT6 that averages well under the EPA 20 mpg combined on a mixed route may have an engine or tire problem.

Why these checks: what owners reported

NHTSA complaints for the 2025 Cadillac XT6, grouped by the part owners named. Open a row to read what goes wrong.

  • Brakes2No crashes

    Brakes lose power assist or fail without warning, and the most serious report links this to a faulty brake booster vacuum sensor. That problem first showed up as a brake assist warning, was repaired at about 6,747 miles, and came back after the repair at about 12,233 miles. Losing braking in traffic carries a real crash risk. Another complaint describes the car braking abruptly and very hard while slowly reversing into a parking space with nothing in its path.

  • Engine2No crashes

    Two different engine-area problems appear in the complaints, both early in ownership. One is an abnormal noise at cold start along with an intermittent vibration while driving, which a dealer called normal. The other is red fluid leaking onto the ground at about 6,700 miles. The dealer blamed faulty transmission bolts and said the fix meant dropping the transmission, which made for a long repair. Neither report describes a stall or a fire.

In owners' own words

Excerpts from complaints XT6 owners filed with NHTSA, as written. Listen for the same symptoms on your test drive.

Brakes
I was backing up into a parking space in a parking garage. I was about halfway into the spot and was not in danger of hitting any vehicles or objects and my vehicle abruptly (extremely hard) braked.

Recall repairs are free at any Cadillac dealer, but the seller may never have had them done. Check each campaign number against the VIN.

    General Motors, LLC (GM) is recalling certain 2023-2025 Cadillac XT5 and 2024-2025 Cadillac XT6 vehicles. The instrument panel may not illuminate when the hazard warning lights, high beams, or turn signals are activated. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 101, "Controls and Displays" and 108, "Lamps, Reflective Devices, and Assoc. Equipment.".

    Risk: Without the illuminated reminder, the driver could fail to turn off the lights when no longer needed. Hazard warning lights, high beams, or turn signals that remain activated unintentionally can confuse other drivers, increasing the risk of a crash.

    Fix: Dealers will update the instrument panel software, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact Cadillac's customer service at 1-800-458-8006. GM's number for this recall is N242447940.
