The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix

While driving vehicle on dry, non slippery roads with slight to moderate curves, vehicle illuminates Traction Loss light, sounds alarm buzzer, and at times applies brakes and dethrottles engine, even when no loss of traction has occurred. This happens while driving on straight roads with slight unevenness. Had to disconnect wheel speed sensor harness to disable ABS/VSC system. When this happens, the vehicle automatically applies brakes to certain wheels and dethrottles the engine, this can pull the vehicle to one side sharply and can cause an accident.

When driving the vehicle regardless of speed or driving condition the traction control system randomly activates (it is always when going around a curve, but road conditions are dry, speed could be 70 or could be 20, there is no loss of control by me as a driver). This causes the car to abruptly brake. The computer system shows no issues when the dealer looks at it. When I deactivate the traction control system using the button the van will still beep loudly indicating a loss of traction control. It will also kick off the cruise control, but does not activate the automatic braking feature. This has been happening daily for 2 months with multiple visits to repair shops.

A/C system has had problems since 2010, they replaced the belts & told me it was fine until the warranty expired.I have had recalls on all the doors, airbags &nav system replaced three times, 2013 A/C was replaced, 2016 A/C replaced again, & A/C is being replaced for a 3rd time along with two other recalls. Tire warnings are persistent. I've never worn out tires or brakes before, except with this vehicle at a rate of every 25,000 miles. (4times td)

ABS, vsc, trac off, brake lights on continuously, plus tire pressure light blinking. This is not normal and also annoying. Toyota doesn't seem to know what the problem is, and is only willing to allow me to spend thousands of dollars to "try" to fix this. Toyota needs to take responsibility! vehicle drives normally. Lights have been on for months. I was driving down the road, with a car load of children, late at night, coming home from a football game when the lights came on. We were driving across a long bridge, on a 6-lane roadway, going about 50 miles an hour. Very scary! I pulled over, but soon realized the care was drivable. I've spent so much money, trying to figure out what is going on. I am seeing online that this is not exclusive to Toyota. Many vehicles exhibit this issue. Instead of helping us fix it, we are suppose to pay mechanics (dealers or individuals), then the problem comes back. Seems no one really knows why this is happening. I've been an exclusive Toyota owner for years. It disappoints me that Toyota won't help.

Powertrain fails at 140,000 miles which is very unusual for Toyota [repair cost ~4000 quoted from dealer]. also, there are plenty of electrical problems starts with failing actuators such as sliding door actuator [$~1500 quote from dealer], HVAC air blend actuators [$~850 quote from dealer]and vehicle stability control solenoids [$~500 quote from local]. please help us and others to shed some light on such kind of issues since it costs too much. In winter time when heater is not working.

Side door is malfunctioning. Had to drive home with it open. Granddaughter had to move to rear because I couldn't get it shut after she got in. Frightening experience. Son-in-law had to use force to get it shut. Haven't used in 3 months until I could afford to have it looked at. There was an extension added to the warranty but said I wasn't eligible. $2,125 + tax to fix!!!!

The passenger side power auto sliding door suddenly can't close ( closed in half way then stuck ), we must use wire tied with the B bar to secure the door. It's very shock why this door is malfunction without notice, made the passengers in dangerous situation while driving on a city street. With a warning light flash and driving slowly to back home, then have Toyota dealer check the problems. Toyota said the cable and motor jam together and just pass extend warranty ( 9 years or 120000 mile when which coming first ) I have pay for expensive repair ($1800). I would say the auto sliding door must have some method to make it close by manual to ensure customer safety.

The airbag sensor light comes on and flashes. It will shut off and turn on randomly. The wire harness under the seat becomes loose or damaged as the seats are moved and airbags are not detected. The light stays flashing and airbags are non-functional. Toyota knows about this but tries to charge thousands of dollars for them to replace their faulty wires.
