Owner report 11759351 · 2026-08-25 (August 25, 2026)
While driving at slow speed (approx 27 mph) on an inclining road, the automatic braking system when off and abruptly slowed down the vehicle. Fortunately there was no one immediately behind my car and there was no apparent reason for the emergency braking. The sidewalk did have a person with a dog off to the right at the time but they were completely away from the car walking on a sidewalk. This could have been dangerous if someone was driving immediately behind my car.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
No selected model years have a complete observation window. Choose an eligible year or a shorter window.
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
