2023 TOYOTA BZ4X Complaints

235/50/R20. Found driver side rear tire completely flat in personal garage yesterday morning and passenger front tire had low psi warning on as well. Used the fix-a-flat kit that came with my car to fill driver rear and able to get to shop. Car/tires have 5000 miles on them. Tire shop could not find anything wrong with the driver rear tire but stated a puncture was found in passenger front tire well and did patch that. I see this has been reported before on a Toyota Bz4x same year and same tire with mileage the same as well. I am concerned this could be an issue going forward and am scared to drive this car now any distance especially since there is no spare and I have to purchase a replacement cylinder for the fix-flat.

Twice now on highways in medium rainfall, with lots of water on the road and a lot of spray, the assisted cruise control has failed to identify a vehicle in the lane in front of it, and continued to accelerate towards braking vehicles. One such occasions I was within 3-4 car lengths of the vehicle in front of me.

For the 6th time, the car is without power. It will not start although the starter battery was changed by the dealer on 5/28/24. The EV battery does not show any power. This is the 6th time that car will not start and without power. It was bought brand new on 1/1/2023.

Car was 80% charged.Headlights flashed for a few seconds, dashboard displayed time (7:08 am)and mileage (17734),and message “parking brake unavailable.” Toyota roadside service was called; the tow truck driver jump-started the car, and stated “ the car battery was at 4%. It should be a minimum-of 12%. It is the battery that starts the car.” BZ4X was dropped off at the dealer, Toyota Vallejo. I asked if the battery can be replaced, service manager(SM) reported only if the diagnostics warrant it. Per SM, starter battery was charged.” Dealer unable to reproduce what was causing the electrical problem and what was “draining the battery.” 3) On May 20, 2024 @ 6:28 am, the car had a total black-out. The car did not start and there was no electrical power. Roadside service was called. Per tow-truck driver, “battery was less than 4%.” The car was towed to the dealer, Toyota Vallejo.

Toyota BZ4X was kept overnight by the dealer service dept.Toyota Vallejo was in possession of car from 5/20/24 to 5/21/24. Per ASM, “we could not find anything wrong.” I asked if the battery that starts the car can be replaced, he denied and stated, “only if it fails the diagnostics.” A copy of the thorough checklist was not provided to client upon pick-up of vehicle.Miles was 18878. 4) On May 26, 2024 a 8:31 am,the car did not start and had a complete black-out. No electricity. The car battery was charged at 80% as is customary and in prior events. It is the Memorial Day weekend and service dept hours are limited. Car always parked in garage.

THE INTERIOR OF CAR HAS A VERY GLOSSY finish on the interior especially by gear shift The sun will hit at certain times and flash very bright rays into your eyes. I complained to dealer and sent video when first got car and said nothing they could do and to call toyota,I called toyota(sent same video) and said nothing they could do but flip the visor down.(I tried flipping visor down and still blinding reflection i called lawyer said nothing they could do .IN OWNERS MANUAL says to contact NHTSA if safety problem and figured give you a try ive read online about other people complaining about same problem but have no idea if sent any complaints to NHTSA not able to download video but had few pictures

The contact owns a 2023 Toyota BZ4X equipped with Bridgestone Tires, Tire Line: Turanza EL450, Tire Size: 235/50/R20, DOT Number: EJYB. The contact stated that while his wife was driving at an undisclosed speed, the low tire pressure warning light illuminated on the instrument panel, prompting her to pull to the shoulder of the roadway. After a visual inspection of the exterior of the vehicle, the driver observed that the front passenger side tire was flat. The vehicle was towed to the dealer. After the dealer inflated the tire, the contact observed severe bubbling of the sidewall, requiring the tire to be replaced. The vehicle was repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 5,000.

I drove my 2023 TOYOTA BZ4X home from work after a heavy rainfall in Galveston, Texas in January 2024, had about 2-3 inches of rain on the road, driving about 15-20 miles per hour on my way home. Both front wheel wells/mud guard liners came off. I drove over one of the liner, stopped and picked it up. Also a liner in the back of the car's undercarriage was hanging out. Took the car to the dealership the next morning and was told since it's due to external force/rain. The warranty on a 6 months old car is not covered. Called Toyota cooperate office and was told the same thing. I was quoted $4000 for the repairs. This should not be happening on a new car while driving 15 miles per hour on 2 inches of water on the road. I know it's 2 inches because I stepped out to pick up the fallen piece and checked the depth of water on the road. There should be a recall on this parts. Too many similar complaint on a brand new car/model from Toyota and Subaru owners.

I submitted this form earlier, but I’m unsure whether it went through. If this is a duplicate, please disregard. An incident of sudden, unintended acceleration occurred while pulling into a gravel parking area on a hillside at dusk. While turning, the vehicle suddenly lunged forward and struck a tree stump. It would have been avoided without the sudden acceleration. The driver slammed on the brakes, and the vehicle came to rest right at the edge of a downward slope. Five seconds earlier, and a family member, who had come out of the house to show where he wanted the car parked, could have been killed, or seriously injured. The car was towed to Toyota Of Erie, where it was inspected by a corporate inspector. It remains there until a decision is made. The adaptive cruise control, which was used on the trip, had been canceled, and the brakes were used several times after exiting the freeway. There was apparently no warning from the front camera and the collision avoidance system about the tree stump, though the driver had seen it prior to making the turn. The incident happened very quickly, but there was no noticeable red warning flashing on the screen. This time there is only damage to a car fender, and a tree stump. What about next time? Suppose the vehicle is slowing into a parking space, there is a child exiting nearby van and the car suddenly accelerates? No thanks!!! This problem needs to be solved! The floor mats in the BZ 4X are secured to the floor so they are not an issue. The driver of the vehicle can play an instrument with foot pedals and is therefore very aware of foot placement-so operator error is not the problem. Perhaps there is just too much autonomous driving technology and software layered over the basic EV platform. Can’t we just have the choice of a basic EV until these other problems are worked out? I signed up to be a pioneer in the adoption of electric vehicles, but not a guinea pig for autonomous driving.

The contact owns a 2023 Toyota BZ4X. The contact stated that the driver's side rear-view mirror was shaking violently while driving 55 MPH or higher. The vehicle was taken to the dealer who diagnosed, and the mirror was replaced. The vehicle had not received additional repairs. The manufacturer was made aware of the failure. The approximate failure mileage was 6,100.

Toyota re-installed the accessory wheel locks that does not meet the design requirements of the new hub bolts per FAQ page 1 of 2; Q2B of this SAFETY RECALL 22TA06 – Remedy Notice. https://static.nhtsa.gov/odi/rcl/2022/RCMN-22V444-6442.pdf and Critical Note at the bottom of page 8 on the attached "BZ4X Fix" document.
