For scale, 3,627 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 7 months.
Defect
During manufacturing of the Vehicle Stability Assist (VSA) system, the soldering process used to bond capacitors to the electronic circuit board within the control unit created voids at the cathode terminal junction inside some capacitors. Electrochemical corrosion progressively forms an oxide film within these voids, preventing the capacitor from suppressing voltage-induced electrical noise. As a result, the sensor that detects brake pedal travel malfunctions and triggers unintended brake assist activation. In the worst case, the brakes may apply suddenly without the brake lights illuminating.
Corrective action
On all vehicles, add a wiring harness with an additional capacitor to the VSA modulator control unit.

状況
車両挙動安定化制御システム（ビークル・スタビリティ・アシスト：ＶＳＡ）において、制御ユニット内の電子基板とコンデンサを溶着する際に、コンデンサ内部の陰極端子接合箇所に空間を生じさせたものがある。そのため、当該空間部から電食による酸化被膜が徐々に進行すると、電圧変動で発生する電気ノイズが除去されず、ブレーキペダルの踏み込み量を検知するセンサが誤作動を起こして意図しないブレーキアシストが作動し、最悪の場合、制動灯が点灯しないで突然ブレーキが作動するおそれがある。
改善措置
全車両、ＶＳＡモジュレータ制御ユニットにコンデンサ付きの配線を追加する。
