Specs side by side
What owners say
Q3
Overall
Mixed sentiment with a clear generational divide. Feedback on the second-generation model (2019 onward, often referred to as the F3) is generally positive, with owners praising its comfortable ride, good handling in poor weather, practicality for couples or small families, and the reliable Gen 3 EA888 powertrain. The ability to use regular fuel is frequently cited as a significant positive.
Best version to buy
The 45 TFSI engine (2.0L) is strongly recommended over the smaller 40 TFSI due to adequate power. For trim levels, the Progressiv (Premium Plus in the U.S.) or higher is recommended to avoid overly basic equipment like manual passenger seat adjustments.
Known issues
- ⚠Sunroof leaks – Drains become blocked, causing water ingress into the cabin and headliner. Affects 2019, 2020, and 2021 models specifically. Frequency: recurrent.
- ⚠Excessive road/wind noise – Particularly noticeable at highway speeds, attributed to insufficient sound deadening. Frequency: recurrent.
- ⚠Water pump failure – Faulty component covered by a class action and extended warranty on F3 generation models. Frequency: recurrent.
XT4
Overall
Mixed sentiment with a clear generational divide. Feedback on the 2019-2023 models is notably more negative, centering on significant powertrain reliability concerns, particularly with the 9-speed automatic transmission, and various electrical/infotainment gremlins. The driving experience for these earlier models is often described as uncompetitive, with an underpowered and unrefined 2.0L turbocharged engine.
Best version to buy
For the 2024-2025 refresh, the Sport trim is frequently mentioned as the desirable configuration, offering a more complete feature set. The Premium Luxury trim is also noted for its value.
Known issues
- ⚠**Transmission failures (9-speed automatic)**: Complete failures, torque converter issues, valve body problems, harsh shifting, and slipping, primarily reported on 2019-2023 models. One owner cited a $13,000 repair quote.
- ⚠**Infotainment/Apple CarPlay connectivity problems**: Intermittent failures to connect, system reboots randomly while driving, unresponsive screens. Issues persist even after dealer replacement of components in some 2019 models.
- ⚠**Underpowered and unrefined 2.0L turbo engine**: Engine runs out of breath at higher RPMs, sounds unpleasant, lacks passing power, and is described as "abysmal" compared to GM's larger naturally aspirated engines. Frequency: recurrent.
