“I purchased a new 2021 Toyota Tacoma in december 2021 with a pre collision safety system. Less than 2 months later, my daughter was in a front end collision accident (daughter at fault). The system did not do what it was suppose to, which was warn her and help her apply the brake. At the repair center, I asked them to check the pre collision safety system. They took the vehicle to bert ogden Toyota to have the vehicle checked out. They told me the system was probably off or not set sensitive enough at the time of the accident. …”
NHTSA complaint #11403765, filed 2021-03, 1,000 miles“Vehicle will not hold 6th gear while in cruise control. Vehicle will suddenly down shift to 5th and sometimes 4th. This makes the vehicle surge forward abruptly.”
NHTSA complaint #11412879, filed 2021-04, 150 miles“Upon acceleration vehicle will have delayed engagement, up to and including a near stall or stuttering. Has LED to several near misses (x2). The tss system takes over and does it's thing versus allowing the driver to drive the vehicle for the conditions. Example would be automatic application of brakes due to deer in road causing loss of control on an icy road way. Driver released gas pedal and was coasting as deer was crossing. Due to brakes being automatically applied, vehicle began to slide, deer became spooked and stopped crossing, vehicle ended up partially in the ditch. …”

I have spend a lot of maintenance on this truck on maintaining it to have to remove the engine. As for the forward collision warning ive had it go off multiple times witout a vehicle there. While in cruise control ive had it unexpectedly break on me when there was no visible vehicle infront or next to me.”
NHTSA complaint #11755683, filed 2026-08“Auto Emergency Braking has gotten extremely dangerous and locking breaks when nothing is in front of me. Always while in cruise control mode. On long extended highways, the truck will randomly slam on the brakes and skid the back tires. It has happened 6 times now. This most recent one made us slide into the next lane and I had to turn the truck into a field (~20mph) after the truck brakes went off. To avoid on coming traffic. There was a car turning around half a mile ahead and was nowhere close. Additionally, a severe issue of premature rust and degradation is occurring on the truck. …”
