problem #10

Sienna 6-cyl

  • 32,124 miles


Started to notice this back in Nov 2013 when going downhill or 65 mph. My van steering wheel started to shake and rattle. Brought over to dealership and they didn't find anything except to charge me $125 for diagnostics. Says more likely rotor need resurface. My van still under btob warranty but we're told not covered under warranty. That's ridiculous. Time past 4 months later, still rattling. Brought over to dealership to get it brake/rotor replaced and resurface 3/27/14. Still rattling......very disappointed with Toyota knowing they know the workmanship defects and not accepting it.

Sienna 6-cyl

  • 11,000 miles
While driving 35 mph on a city street, I lost brake function. I was able to coast to a complete stop, thankfully avoiding other traffic and obstacles. Once I was stopped, I found that there was a long bolt on the floorboard underneath the gas pedal. When the towtruck driver arrived, he reached in and pulled the gas pedal completely off - there was nothing fastening it to the car. He was able to reinstall the bolt, but said there was "a piece" missing, and towed it to the Toyota dealership. The dealer found that two pedal pivot bolts were missing, and the one that was present (which had ended up on the floor), was not secured by a nut. They said that they were not sure why this happened - that it could have happened in the factory - but said that they replaced the three bolts and torqued them properly, and that it was safe to drive. We asked to speak with a manager for better explanation, and the manager avoided all of our attempts to contact for several days.

After pulling out of the driveway and driving forward less than 100 yds, the vehicle began to pull left and right as if vehicle stability control were taking over. Very shortly after, the vehicle came to an abrupt stop with brakes seemingly applied on their own (power brake assist?). the screen lit up with the following warnings, "check ABS, " "check vsc, " and "check brake system, " followed by "have your vehicle checked by dealer." The ABS, vsc, emergency brake, and check engine lights on the dash came on as well. Upon taking a look under the hood, we also discovered what appeared to be an oil leak at the head gasket. The vehicle was taken to the dealer and a Toyota engineer was flown in to help diagnose the problem. The result was they cleared the codes, wiped up the oil, and said there was nothing wrong with the car. About a day and a half later, the exact same thing happened again with the vehicle pulling, warning lights, etc. This time, the dealership said that they found "hard" codes and that the floor wire harness needed to be replaced. The vehicle has now been out of service for 16 days. We shall see whether the wire harness fixes the problem. The dealer said they put dye in the engine oil to try to detect a leak. Not sure why they didn't investigate the problem while the oil was sitting there. It was very obvious where the leak was.

  • 10,000 miles
The contact owns a 2011 Toyota Sienna. While driving approximately 10 mph and coming to a stop, the contact heard a loud banging noise in the rear of the vehicle. The contact stated the failure occurred at different speeds and more frequently when driving on the highway. While driving at highway speeds the vehicle began to shake violently. The vehicle was taken to the dealer where the technicians were unable to determine the failure. The technicians suggested the rear brakes, rotors, and calipers be replaced. After the repairs were performed the rear passenger side tire locked twice. The vehicle was taken back to the dealer where the technicians stated the vehicle showed extensive wear and over heating of the parking brake due to driving while the parking brake was engaged. The contact stated the parking brake was not engaged while driving and the overheating only occurred to the rear passenger side brakes. The vehicle was not repaired. The approximate failure mileage was 10,000.

  • 3,900 miles
The contact was driving a 2011 Toyota Sienna. While driving 20 mph attempting to apply the brake pedal, it extended to the floor; however, the vehicle did not stop. He continued to apply the brakes and eventually they started working properly. Two days later while driving the vehicle and depressing the brakes the warning lights illuminated. The vehicle was taken to the dealer who stated that there were fifteen error codes informing them to contact the manufacturers engineering department. The dealer informed her that there was a metal bracket that covered the brake sensor and when the brakes were depressed the sensor informed the computer to turn on the hydraulic brakes in order for the brakes to function normally. The metal bracket on the vehicle was damaged; therefore, the computer did not work properly. The manufacturer was contacted and advised the contact to take the vehicle back to the dealer since they were responsible for the repairs. The vehicle was returned to the dealer who exchanged back her old vehicle to her. The failure mileage was 3,900.
