Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When the car is at idle speed, such as waiting for traffic to clear for a left turn, the car will just die without warning. It will usually restart right away, but this has nearly caused a collision. The dealership in bellevue, wa says that's a normal thing if the car isn't properly maintained. I have brought the car to that dealership for all but one of the maintenance intervals, and the only other time was for maintenance when we were in ohio. Having the throttle body cleaned is not on the routine maintenance schedule. …”
NHTSA complaint #11302373, filed 2020-01, 36,650 miles“The fuel pump intermittently fails. Sometimes it won't start at all, sometimes it starts but the engine stumbles before it shuts off, and sometimes the engine will just shut off while accellerating on the road. Toyota has diagnosed it as a bad fuel pump and are in the process of replacing it at my cost.”
NHTSA complaint #11351862, filed 2020-08, 42,500 miles“Fuel door latch hinge is broken at the top of the hinge. Possibly, it caused by the door latch safety with excessive tension. It disabled the driver side sliding door. Driver's side sliding door could not be opened and it caused exiting issue for children and occupants in the car. Car's mileage is at 27,000 miles. Fuel door opened during in motion and/or stationary.”
NHTSA complaint #11048124, filed 2017-11, 27,000 miles“Fuel tank access door hinge is broken. Can't fill gas tank up. If fuel door is removed sliding door won't open. Fuel door hinge broke because the fuel door pin has so much tension that it broke the hinge. This caused a safety issue because the door cannot be opened from the inside if it is not closed all they way or pushed closed enough for the sensor to allow the sliding door to open. This event was reported past the 36 month warranty, (at 40 months, but less than the mileage warranty), but had begun before the warranty had ended. …”
NHTSA complaint #11119526, filed 2018-08, 55,600 miles“There is an EVAP emission leak and the P0456 error states the gas cap is faulty. I had it replaced and replaced again. So I am waiting for another brand new gas cap-3rd brand new one. So 4th overall for this van. A smoke test was done and there is no leaks per the test. So if this continues after the brand new gas cap, then there should be a recall as the gas cap is an issue. Started to happen after 95,000 miles. The AWD is shut off and goes to 2 wheel drive, traction control is turned off, Check Engine light comes on and Message Check AWD system comes up on the screen. Any recommendations”
