Lexus UX problems and known issues

By CarWhere Research · Updated November 5, 2026

The Lexus UX has few documented problems and a short recall list. The notable campaigns are a brake booster pump on the 2019 UX 250h (19V544), an in-tank fuel pump on the 2019 UX 200 (20V682) and, on the 2025 UX 300h, a motor-generator ECU wiring harness (24V587) and cluster display software (26V341).

CarWhere lists 4 documented UX issues, including 4 NHTSA safety recalls, each with affected years, powertrains, symptoms, pre-purchase checks and a source. Recall entries come from NHTSA's recall dataset on the DOT open-data portal, which may not list every campaign, so run the specific VIN through NHTSA's recall lookup.

Frequently asked questions

Does the Lexus UX have any major recalls?

The UX recall list is short. 19V544 covers the brake booster pump on some 2019 UX 250h, 20V682 replaces the fuel pump on some 2019 UX 200, and 24V587 replaces a wiring harness on 141 early 2025 UX 300h models that could lose drive power.

What changed with the UX 300h?

For 2025 the UX 300h replaced the UX 250h and became the first Lexus with the fifth-generation Lexus Hybrid System, a 2.0-liter four-cylinder paired with two motor-generators. Its early recalls are the harness campaign 24V587 and cluster software update 26V341.

How long is the UX hybrid battery warranty?

For model year 2020 and later Lexus hybrids, including the UX hybrid, the hybrid battery is covered for 10 years from first use or 150,000 miles, whichever comes first. 2019 UX 250h models carry the earlier 8-year/100,000-mile hybrid coverage.

How do I check a used Lexus UX for open recalls?

Enter the 17-digit VIN in NHTSA’s recall lookup or ask a Lexus dealer. Recall repairs are free regardless of mileage or owner, and the dealer can print the completed-campaign history.
