4 known faults with sources

Engines: 1.5 VVT-i (Petrol) · 1.5 Hybrid (Hybrid)

Applies if: Toyota USA tech tip for all its models: it applies if the judder began after wheels, pads or discs were removed or changed.

Brake judder from wheel nuts over-tightened or tightened unevenly (Toyota tech tip)Brakes

Engine / equipment: Any Toyota: it depends on how the wheels are tightened
Period mentioned: 2016 tech tip for all its models
Symptoms: Vibration in the steering wheel and the pedal when braking, even gently and at any speed, often shortly after wheels, pads or discs were changed.
Possible cause described: Toyota points out in a tech tip that if the wheel nuts are over-tightened or tightened unevenly (a single one is enough), the brake disc is left with runout and brake judder appears. It happens above all when they are run fully home with an impact gun instead of a torque wrench in a star pattern.
Check for the garage: Ask the garage to loosen and re-tighten the nuts with a torque wrench, to the manual's torque and in a star pattern, and to measure whether the discs have been left warped; if so, they will need skimming or replacing.

Engines: 1.5 VVT-i (Petrol)

Instrument cluster that goes blank because of its memory (Yaris and Yaris Cross)Electrical and electronic systems

Engine / equipment: Toyota Yaris and Yaris Cross
Period mentioned: 2022–2025
Symptoms: The cluster goes black: the speedometer and warning lights cannot be seen.
Possible cause described: A 2025 Rapex alert (Toyota campaign 25SD-063, about 900,000 cars of several models worldwide) says a programming flaw wears out the instrument-cluster memory and the display may stop working.
Check for the garage: Check campaign 25SD-063 by VIN at a Toyota dealer.
Cost cited in the source: Free under the recall.A rough figure from the original database, not an up-to-date quote.

Engines: 1.5 Hybrid (Hybrid)

Applies if: The Toyota USA bulletin does not list this model, but its hybrid battery is also cooled with cabin air through a filter.

Clogged hybrid battery cooling fan and filterHigh-voltage battery

Engine / equipment: Hybrid battery cooled with cabin air (intake next to the rear seat): Prius, Yaris, Auris, Corolla, C-HR, RAV4, Camry and others
Period mentioned: 2003 onwards
Symptoms: Hybrid battery cooling maintenance message, warning light with codes P0A80 or P0A7F, a noisy fan and less electric assistance; if ignored, the battery ages faster.
Possible cause described: Dust, pet hair or dirt block the filter and fan that cool the battery; so do objects covering the intake. Toyota USA issued bulletin T-SB-0074-20 (2003–2020 Prius and Camry, Corolla, Highlander, RAV4 and Mirai hybrids up to 2020) and recommends cleaning the filter every 5,000 miles (about 8,000 km).
Check for the garage: Clean or replace the filter and clean the fan before condemning the battery; keep the intake grille clear. At the garage, read the codes and, if needed, install the software Toyota specifies.

Engines: 1.5 Hybrid (Hybrid)

Applies if: Built before February 2024 (since then they have a higher-capacity 12 V battery).

Will not start because of a flat 12 V battery on the Yaris and Yaris Cross hybridsElectrical and electronic systems

Engine / equipment: 1.5 hybrid: fourth-generation Toyota Yaris and Yaris Cross
Period mentioned: 2020–2024
Symptoms: After a few days parked, the car will not start (it does not go to “Ready”) because the auxiliary 12 V battery is very low or flat. It mainly affects people who drive few kilometres.
Possible cause described: According to an internal 2024 Toyota technical note reported by L'argus (March 2025), the original 12 V battery was too small to recharge quickly enough while driving. Since February 2024, Yaris and Yaris Cross built in France and the Czech Republic have an LN0 12 V 35 Ah battery with twice the charge capacity.
Check for the garage: Measure and test the 12 V battery. If the car was built before February 2024, ask Toyota to replace it with the new higher-capacity battery (the part number depends on whether the battery was fitted before or after October 2024). In the meantime, make somewhat longer trips or use a battery maintainer if the car stays parked for days.
Cost cited in the source: Toyota replaces it under the 3-year or 100,000 km warranty.A rough figure from the original database, not an up-to-date quote.
