NHTSA Complaint #11447818 — 2017 TOYOTA HIGHLANDER

When the vehicle was ~1.5 years old following its 10,000 mile maintenance, substantial thumping generated from the rear of the vehicle. Each time, the dealership attempted to resolve the problem finding issues with struts; however, it only went away in late March after having the vehicle in the shop for weeks at a time on 5 different occasions Nov 2018 - Mar 2019. I engaged Toyota HQ (800-331-4331) - filing report #1901092572 - requesting an exchange of the vehicle. This was denied and I was offered a 8 year warranty. *Due to COVID, I rarely drove this vehicle through 2020 and most of 2021, where to date, I have only ~34,000 miles on the vehicle. -On 21 Oct 2021, my wife was stopped at a gas station and attempted to start the vehicle. The vehicle would not start and the following lights came on without previous warning: 1)Braking Power Low, 2)Maintenance needed soon, & 3)Orange yellow triangle lit up with exclamation mark. My wife was stranded for 3 hours and the vehicle had to be towed. The dealership informed me that Toyota installed a generic battery into the vehicle (when being sold) that was only to have 4-5 years of life; however, my concern was that this vehicle had just completed maintenance and there was no warning of this upcoming issue. When repaired, I had to pay for the name brand (True Start) battery. -On 16 Jan 2022, after having driven the Highlander for 25 minutes, I started the engine while in a parking lot. While moving forward and the engine still going, the brakes and power steering went out. On the dashboard, the same lights that came on in Oct 2021, did so again. I had to let the vehicle coast (having no control) with my wife and child in the car through the parking lot. It came to a stop at the concrete parking curb stop at a store front. Toyota stated that since there was no check engine light that there was no code and they could not duplicate the problem. The vehicle was sent back to me with no resolution or explanation.
