TL;DR
The Lexus UX is a generally reliable compact SUV, but common issues include engine roughness, transmission hesitation, suspension wear, and infotainment faults, particularly in early models. Regular maintenance and prompt attention to recalls can help maintain its performance and safety.
Engine Problems
The Lexus UX features a 2.0-litre four-cylinder engine, with some owners of models from 2019 to 2021 reporting rough idling and reduced power. While these issues are not widespread, they can impact the driving experience. Regular maintenance, including monitoring engine oil levels and timely oil changes, can help prevent these problems.
Transmission Issues
The UX uses a continuously variable transmission (CVT), which generally provides a smooth driving experience. However, some 2019 models have experienced hesitation during acceleration, particularly noticeable when merging onto motorways. Regular servicing of the transmission fluid can help maintain performance and reduce hesitation.
Suspension Concerns
Suspension problems have been reported in models from 2019 to 2022, with owners noting premature wear on front suspension components. This can lead to a rougher ride and handling issues. Regular inspections can help identify these issues early, and upgrading to higher-quality aftermarket parts may improve suspension longevity.
Electrical Faults
Early models from 2019 have experienced electrical problems, particularly with the infotainment system, which may freeze or reboot unexpectedly. Keeping the system updated with software updates from Lexus can resolve these issues. Additionally, ensuring the vehicle’s battery is in good condition can help prevent electrical problems.
Recalls and Safety
The Lexus UX has had recalls related to fuel pump issues and safety features. Checking the DVSA website for the latest recall information specific to your vehicle is essential. Addressing any recall notices promptly can help ensure your vehicle remains safe and reliable.
