After the weather drop to 45 degrees on October 5, 2014 I started my 2012 Toyota Sienna (AWD), I immediately notice that all light in the panel were on. There is warning in center view panel alerting me that I need to take the vehicle to dealership for ABS, vsc and brake system problem. The following day I drove the vehicle to the dealership and notice that the speedometer and gas gauge are not working. The speedometer hand is moving back and forth. The gas is always in the full mode. I also notice that the brake is always in on mode. Driving without working speedometer, brake system and gas range are really putting my life in danger. I am hoping that my dealership which superior Toyota can fix these problem. I am also hoping that warranty will covert the defective part.

When braking at normal speeds on the road or the freeway, the car vibrates/shakes. According to the dealership the rotors are warped. At 12,000 miles, this seems to be an under-engineered part on this heavy van, which appears to be uncorrected on the newer model (2013 and 2014) as well. The repairs are not covered under warranty. The only other option is to install aftermarket heavy-duty rotors, an expense that the consumer should not have to pay.

Sienna 6-cyl

  • 5,000 miles
Owner was driving and vcs and ABS warning lights came on and stayed on while driving as well as tire pressure light. Brakes on vehicle did not brake as well going down hill. Tires slipped and skidded in the rain on the hills in ventura county. Driver called Toyota and they opened up a case number. Toyota has attempted to fix the vehicle 3 times and cannot determine the reason why the malfunction keeps occurring. Owner has video of the warning lights continuously on while owner is driving. Owner feels this is an extreme safety issue, and believes they were sold a lemon car.
