2020 Toyota Highlander

We purchased the highlander a few days ago from a Toyota dealership. There are currently no recalls that have not been addressed and the car seemed to be in great condition. Driving the last few days there have been times that the brakes just don't function properly. I went online to see if this was an issue that had been reported. I found this description below and it is exactly my experience as well. This site has the other complaints that match my experience. Feeling like you don't have brakes for a few seconds is going to lead to accidents. I have a 2005 Highlander and I am sad I spent so much money and would feel safer driving my old car. It has not been confirmed by a dealer, or inspected, and there are no lights on the vehicle. I don't know where to go for an honest assessment. https://m.carcomplaints.com/Toyota/Highlander/2020/brakes/service_brakes.shtml I have experienced brake issues, on any slight decline where the braking system will let up as if the braking is not working for a moment, and also, a jerk forward once stopped. This will lead to an accident and potentially, a pedestrian getting hurt if not addressed. I took it to the dealer and they stated they could not replicate the issue, therefore, did not run diagnostics on the vehicle and will do nothing else for me. I have great concern this will lead to an accident and after 30 years of driving, I'm having to constantly think of leaving enough room between myself and other cars to avoid an accident, and adequate room for a brake malfunction. I have another 2020 hybrid Toyota that does not have this issue. So, it is not an issue with all hybrids. - Berkley, MI, USA

I pulled my vehicle into the driveway and stopped outside of the garage. I stepped out to fold my mirrors on both sides of the vehicle as the garage is very narrow. I also need to unload my belongings from the rear hatch. I walked around to the Right side mirror, folded it and headed to unload the hatch when the vehicle PULLED ITSELF INTO THE GARAGE; literally! I could not open the doors as they lock and the space is so narrow. The vehicle stopped when it hit the back wall of the garage. I immediately opened the door and turned the vehicle off. The Vehicle sounds an alarm and shows the message "Shift to park" if not in Park. This did not happen. I sat in the car putting my sunglasses away and unplugging my phone before exiting. If I had not put the vehicle in Park, I would have heard and seen the warnings immediately and the car would have moved immediately; not 30-60 seconds after exiting. Note: our driveway is flat

On several occasions the brakes will get very weak and you have to apply normal than normal pressure. There’s a second where it feels like the brakes have failed. All occasions have been on dry flat roads. This last occasion I was turning into a grocery store driveway and in the turn the brakes failed and I had to press hard and turn harder or I would have ran into the car leaving the driveway. It’s not the hybrid system. I’ve owned prior Toyota hybrid and the brakes don’t give out like this. Sometimes it’s less that 5MPh but it’s also done it at 10-15mph. Both times the batteries are not fully charged so there isn’t any reason why the regenerative breaking should be suddenly shutting off causing the breaks to feel soft.
