Example complaints

“System will occasionally suddenly decelerate as I am passing, usually a large truck. I will be in adaptive cruise control and as I get abreast of the trailer, the vehicle will suddenly decrease speed by 10-20 MPH, then accelerate back to the set speed. This, obviously, has the potential to create a rear end collision if someone is following and not paying full attention, esp if there are multiple cars following. This has happened multiple times.”
NHTSA complaint #11402933, filed 2021-03, 18,000 miles“This morning I activated my cruise control (cc)as I normally would at 55 MPH. Immediately my truck began accelerating until I finally disengaged cc when the speed reached 83-85 MPH. It was still accelerating at the time I disengaged it. I attempted to recreate the incident with no luck. Before the incident, I was driving in a city environment at speeds less than 55 MPH, so there was no way I had previously set the cc to a high speed that would have caused this to happen had I hit resume.”
NHTSA complaint #11404107, filed 2021-03, 10,500 miles“Toyota has a manufacturing defect going on with their v6 in Gen 3Tacoma's. I have a 2020 Limited with 48,200 miles that needs a new cylinder head. It threw a check engine light on me, and luckily enough I took it to the dealership within about 30 miles, otherwise my engine could have exploded. I have videos from the dealership inspection that I cannot attach here. I have since found via the error code a history of these issues on newer trucks. …”
NHTSA complaint #11712671, filed 2026-01“My wife was backing up in our driveway, and hit another vehicle parked in our driveway. The backup pre-collision system did not issue any warning, and did not stop the vehicle (as it is supposed to do).”
NHTSA complaint #11461873, filed 2022-04“The issue is that I and as well as many others live in cold winter climates. LED headlights do not put off the heat required to keep snow and ice off of them. This is a hazardous and accident causing issue when you can not see any longer. Getting out of the vehicle every few miles poses a hazard in it's own that you are pulling over on a roadway to clear the headlights. I don't feel the manufacturers thought this through and is getting worse that most newer vehicles & all electrical vehicles have LED lighting. There needs to be a heater system or film/built in heat source for the lens.... …”
