Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The first weeks seemed like everything was fine with the vehicle until we started feeling low levels of electrical shocks. It was mostly on the steering wheel so we thought that the sensation would go away, but it actually started going worse to the point that we started having discomfort on the seatbelt and the last three weeks before we dropped the vehicle at the dealership the hazard started to intensify and get stronger. …”
NHTSA complaint #11319901, filed 2020-04, 7,000 miles“The power sliding door on the driver’s side of the vehicle is malfunctioning. When the door is opened with the electric opening function, it detects resistance and starts to close. While closing, the door closes with great force and no longer attempts to detect closing resistance. Me, my wife, and my infant daughter have been crushed/trapped by the door. My daughter had her arm trapped in the door. My wife had her back crushed. The Toyota dealer in Tucson, AZ (Precision Toyota) said the electrical cables inside the door are binding, causing the resistance when opening. …”
NHTSA complaint #11472348, filed 2022-07“The microphone has an issue and it is tied to the SOS call button in the car. I asked my dealership, they wanted to charge $200 to run a diagnostic scan, I contacted Toyota directly, they basically said the dealer can charge it if they want and reverse the charge if they find a problem under warranty. I originally thought the issue was with the Blue Tooth. I found this video on YouTube, his fix did work-my concern is, if I had needed Emergency help-the button would not have called anyone, disconnecting your car battery is NOT something I should I have to do to fix a 2019 vehicle. …”
NHTSA complaint #11499369, filed 2022-12“I have a concern that the frontal impact sensor on my van may not be working. I bought the van new about 3 weeks ago. In that time I have driven it around town, on the freeway and made a roundtrip to cal. In that entire time I have never received any type of audible or visual alert that a frontal impact is about to happen. I have the sensitivity set to very high. Over the course of the last few weeks, I have tried to safely simulate the conditions in which the frontal impact should activate, but I have not heard anything or seen any type of visual alert. …”
NHTSA complaint #11234122, filed 2019-07“Started hearing a whining noise upon acceleration. Took car to Toyota for a diagnostic check. Discovered transmission is failing. Recommended repair is a full transmission replacement, quoted $10,000. After bringing to a local mechanic for a second opinion, he claims this is a widespread issue with Toyota Siennas in similar years. After some research, Toyota quietly claims there was an issue in the manufacturing of these transmissions however won’t take accountability”
