Unconfirmed issues

Reported

Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.

Old trackpad infotainment (pre-facelift)

Pre-2020 facelift only

Cars built before the 2020 facelift use Lexus's original Remote Touch trackpad to control sat nav, media and apps, and it is widely disliked. Reviewers called it fiddly and slow to respond, and owners report having to look away from the road to hit the right menu item. There's no fix for the hardware itself; Lexus's answer was to drop the trackpad altogether and fit a normal touchscreen from the 2020 model year on. Not a reliability fault as such, but it is a real cost to check for at a test drive since retrofitting the newer system isn't practical.

Interior rattles and panoramic roof squeaks

Emerging

A recurring owner complaint across the UX250h and UX300h: creaks and rattles from A-pillar trim, the centre console and dashboard, plus a squeak from the panoramic glass roof over bumps. It shows up from fairly low mileage and doesn't seem tied to one age or engine. Fixes are mostly DIY, retensioning clips or adding foam packing, since Lexus hasn't put out an official bulletin for it. Annoying rather than costly, but worth listening for on a test drive over rough surfaces.

UX 300e: 12V battery goes flat if left standing

Electric (300e) only

On the UX300e, the small 12V battery that runs the car's electronics can drain flat if the car sits unused for a week or two, leaving it needing a jump start or dealer reset. Owners trace it to the standby power draw from the car's connected services module. Lexus has issued a software update through dealers that owners report largely cures it, so ask whether that update has been done on any 300e you're viewing. A replacement 12V battery is cheap, but repeated flat batteries point to the update not being applied.

UX 300e: real-world range and slow charging

Electric (300e) only

Early UX300e cars (2020-2022) carry a modest 54kWh battery and owners consistently report real-world range well short of the claimed figure, especially at motorway speeds, plus CHAdeMO rapid charging that's slower than most rivals' CCS setups. Lexus fitted a larger 72kWh pack from 2023, which pushed usable range up noticeably. Not a fault that breaks down, but it changes what the car is actually usable for, so check the battery size and expected range against your own driving before buying an early one.

Hesitation pulling away on early hybrids

Disputed

Some early (around 2019) UX250h owners describe a moment of hesitation or lag when accelerating hard from a stop or merging onto a motorway, before the hybrid system delivers full power. It's not universal: plenty of owners and forum regulars argue the eCVT is one of the more dependable hybrid transmissions around and dispute that this is a fault at all rather than just how the system behaves. No TSB or recall exists for it, so treat it as a drive-it-and-judge item rather than a confirmed defect.

Viewing one? Ask this

Built from the two sections above.

If it's a pre-2020 car, work the infotainment trackpad through a few menus while parked. Slow or fiddly response is the old Remote Touch system, not a fault you can fix.
Drive over a rough patch of road or speed bumps and listen to the dash, A-pillars and roof. Creaks or a squeak from the panoramic roof point to the common trim rattle complaint.
On a UX300e, ask if it's been left standing for a week or more recently and whether it needed a jump start. A history of flat 12V batteries suggests the software fix hasn't been applied.
On a UX300e, ask the seller to show a full charge and note the indicated range. A big gap to the claimed range is normal on early cars but worth pricing into your offer.
From a standing start, floor the accelerator on a hybrid model. A flat spot or hesitation before power arrives is the reported early-car lag; smooth pickup means it's fine.
Check the service history for any software update stamps. Missing updates mean known infotainment or 12V fixes may not have been applied.
Read the full MOT history rather than just the pass/fail. This model has no strong measured MOT fault pattern, so a clean history here is a genuinely good sign.
