Toyota is reluctant to confirm this vehicle is meeting Federal Motor Vehicle Safety Standards except labelling and it is safe to drive in United States roads. This vehicle is equipped with TPMS but it is not listed as a part present in the vehicle which makes me worry.

At speeds between 25–40 mph, there is a significant cabin boom and echo inside the vehicle. This creates a pressure sensation in my ears, causing nausea, disorientation, and physical discomfort. I’ve only driven about 50 miles, and the symptoms are severe enough that I cannot continue driving the vehicle. Look up ODI 11697688 at NHTSA ↗ |

The hesitation causes a lag in the vehicle and it then will jerk or jolt while shifting. The vehicle will Rev up in a low gear and not shift correctly. This causes a safety issue especially when going into traffic. I have not taken it to the dealer as of yet, but I will be. This is an intermittent issue, so i fear toyota will say they cannot replicate the issue. There were no warning lamps when the event happens. Look up ODI 11762019 at NHTSA ↗ |
