Complaint evidence
Examples provide context, not a representative sample or a verified diagnosis.
The contact owns a 2026 Toyota Crown Signia. The contact stated that while driving at approximately 20 MPH, a neighbor's dog darted into the street. The contact depressed the brake pedal, and the Pop Up Hood system deployed without contact with the animal. The Pop Up Hood system was designed to raise the hood automatically to absorb and reduce the impact energy on a pedestrian's head and chest. The hood could not be closed after deployment. The vehicle was towed to the dealer, where the contact was informed that the hood lifters required replac…
This has to do with the lane departure system. When on unmarked roads with the lane departure system turned off the car still pulls the car. Sometimes to the center of the road. The steering can be overcome by countering the departure system but we must be very vigilante so as to not let the car steer itself. I informed the dealer about the problem and they told me it was normal. I think there is a software problem or something.

The car was leased on 12/18/2024. On 01/24/2025, after starting the vehicle, the check engine light came on with the description: "a malfunction in the electronic control of the engine, throttle, or automatic transmission has been detected. Contact your Toyota dealer to have your vehicle inspected." I am attempting to get an appointment now to get the car in for service but being a month old - this shouldn't be happening.

While driving less than 10 mph, (slightly down hill) approaching the house garage, the car suddenly accelerated and the brake was applied to stop but the car continued and smashed through the garage door, proceeded through garage, smashed through the back of garage, hit a Weber gas grill, proceeded over a low-level deck and hit a large tree. The impact force of the car (left front) against the tree caused the car rear end to rise up and move 30 degrees to the right and land on the low-level deck. The driver was the only person in the car and s…
I had buckled my seat belt and was grabbing my work phone, Iphone 13, to check it before leaving. I accidentally dropped it and it landed on the red part of my seat belt buckle. My seat belt automatically unbuckled. I was able to replicate this several more times. There is something going on with the engine where if you accelerate there is a coolant type smell then if you take your foot off the gas it sounds like the rpms are staying high. I've seen no warning lights for the car.
Two issues: 1. Low-beam headlights shine way too low on the road and unsafely prevent adequate vision of potential road hazards or oncoming cars, and my model "Limited" only has "automatic headlight leveling" without any way to manually set level to raise up the beam to a safe level. 2. Low-beam headlights cast on the road a distracting dark outline of an attachment or harness plug attached to the LED bulb.
As I was driving down a suburban road at about 30mph the brakes suddenly came on by themselves for few seconds as I approached a parked car on my right side. As I started to pass this car my vehicle continued moving forewarned and I did not come to a complete stop. There were no cars in front or behind me except for the one car parked to my right. There were two electric beeps when the car braked.
When leaning on the front seat center armrest, the armrest makes a clicking noise when hitting rough or bumpy roads. The Toyota dealer replaced the armrest, and the same issue occurred. Toyota told the dealer they want the part to investigate further.

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.
