The forward collision warning goes off and automatically slams the breaks, when nothing is in front of it. It does this on highways as well. This could cause accidents. There is been several complaints about the CVT transmission. If they won't recall it, they should have a lifetime warranty. Toyota transmissions used to last. I cannot afford to get a whole new transmission, so I have to sell it to a dealership.

On 2/13/2023, an object hit my windshield & it cracked. I filed a claim with my insurance & took it to Safelite. Safelite replaced my windshield on 2/27/2023, however, they were not able to recalibrate the sensors within the windshield. This means 3 safety components in my car no longer work, which are; lane departure, cruise control, & pre-collision. I now have a flashing warning in my dash constantly because the sensors embedded in the windshield aren’t calibrated, which is a hazard. I filed complaint #11448934 on 1/26/2022 with the federal safety agency explaining how my pre-collision system was giving me problems. Safelite is going to try a different glass and then try to recalibrate on 3/4/2023. My car is available upon request. My & others safety are put at risk because Toyota opted to put important safety features in one of the most exposed & vulnerable places on a car, that I quite frankly wasn’t aware of until it cracked. I have not had it evaluated by the manufacturer, independent dealer/service center and it has not been inspected. There haven’t been any accidents.. yet. I will upload a picture of the Safelite work order. You will see it says, “Recal failed”

Today suddenly, the vehicle gave me a warning message to "Pull over in a safe spot and to not drive the vehicle" along with other messages flashing "Braking power reduced" "Pre-collision system failure" and a bunch of lights came on. Mechanic, over the phone, said "He doesn't understand how a minor rear-bumper colission could affect sensors and electrical things in the front of the car. Another incident, last year, a small nick on one of the wires under the car disabled my entire car and it was undriveable until repaired. I am frustrated that one small issue with a wire, or sensor, or other small gadgety things in the vehicle can disable the entire car and put me in danger while driving.
