Is the Audi Q4 E-Tron more reliable than the Cadillac XT6?

No. The XT6 holds a slight edge. Both rate well, but Q4 E-Tron owners file far more complaints per car sold, and two of the Audi's problem areas, electrical and steering, include crash reports. The XT6 has one crash-linked area, back over prevention.

Which has more recalls, the Q4 E-Tron or the XT6?

The XT6 has more. Federal recall records show 14 across seven model years for the Cadillac and 5 across three model years for the Audi. The XT6 has been sold for more years, so it has had longer to collect them.

Which costs less to repair?

Only the XT6 has repair-cost data here, at an estimated $783 a year. No comparable figure exists for the Q4 E-Tron, so a fair cost comparison is not possible. Get an independent inspection and a quote before buying the Audi.

What goes wrong with the Audi Q4 E-Tron?

Electrical faults lead the list. One owner reported the car surging forward instead of slowing when braking, and another saw a high-voltage battery warning. Smaller groups of reports cover sudden shutdowns tied to the seat sensor, AWD warnings, and tire tread separation.

What are the common Cadillac XT6 problems?

Power train and electrical complaints lead. Owners report rolling forward after shifting into reverse and rear camera screens cutting to black. Some reports involve stalls blamed on a failed fuel pump control module. Silent rear parking alerts also appear, including one low-speed collision.

Audi Q4 e-tron vs Cadillac XT6: Reliability Compared

Audi Q4 e-tron

More Reliable

Cadillac XT6

Good

Cadillac's XT6 edges out the Audi Q4 E-Tron on reliability, mainly because owners file far fewer complaints per car sold. The Audi has fewer recalls, but its braking and electrical reports are more worrying, and the lead is slight.

How Do the Audi Q4 e-tron and Cadillac XT6 Generations Compare?

Every XT6 you can buy used belongs to the first generation (U26), which ran in the US from 2020 through 2025. A second generation is expected for 2028, so no redesign is close. The weakest years, 2020 and 2022, sit early in that run. The Q4 E-Tron is first generation (F4), which covered US model years 2022 to 2024. A facelift followed for 2026. That makes 2024 the pre-facelift car and 2026 the updated one. The 2026 has had little time on the road, so its short complaint record does not yet prove much.

Verdict

The Cadillac XT6 is more reliable than the Audi Q4 e-tron, scoring 73/100 vs 69/100.

A slight edge goes to the XT6. Both cars stand well, but Q4 E-Tron owners file far more complaints per car sold, 37.9 per 10,000 against 0.9. Two Audi problem areas, electrical and steering, include crash reports. The XT6 has more recalls, 14 across seven model years against 5 across three, but it has also been sold for many more years. That longer run gives it more time to collect recalls, so the gap in recall counts says less than it seems to.

What Are the Common Problems With the Audi Q4 e-tron and Cadillac XT6?

Complaints on the Q4 E-Tron center on the electric drivetrain. One owner reported the car surging forward instead of slowing, a loss of regenerative braking at about 50 mph. Others describe a high-voltage battery warning, sudden shutdowns tied to the driver's seat sensor, and tread separation on tires. The Audi has two crash-linked areas: electrical and steering, where a car accelerated on its own. XT6 problems are different: rolling forward after shifting into reverse, camera screens cutting to black, and stalls blamed on a failed fuel pump control module. Its only crash-linked area is back over prevention, where rear parking alerts stayed silent.

Best years to cross-shop: The 2024 Audi Q4 e-tron scored 65/100 and the 2024 Cadillac XT6 scored 73/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the Audi Q4 e-tron vs the Cadillac XT6?

Pick the XT6 if you want the lower complaint rate and a known repair budget of $783 a year. Check the camera and parking sensors on any test drive, and ask whether the fuel pump control module has ever been replaced. Avoid 2020 and 2022, the weakest years. The 2025 and 2026 models rank strongest, but they have had less time to collect complaints, so treat that as a lean, not proof. Pick the Q4 E-Tron only if you want an electric SUV and can accept more risk. Test how the car slows when you lift off the accelerator, and check the tires for tread wear. Ask whether the seat sensor has ever shut the car off. Model years run 2024 to 2026. The data lists 2024 among the weakest years, and 2026 is too new to call safe. Run the VIN for open recalls before you buy either car.
