2008 Toyota Sienna engine problems

“The head gasket that was repaired failed and the radiator system also failed. Im not sure if these issues are dealer related or manufacture related as i spoke to the previous owner and they stated they had the vehicle serviced at a manufacturer prior to doing a trade in with the dealer”

“The contact owns a 2008 Toyota Sienna. The contact stated while pulling into a grocery store, he heard an abnormal ticking sound. The contact stated upon parking and inspecting the outside of the vehicle, he noticed that engine oil was leaking onto the ground. Additionally, the oil dipstick was dry upon inspecting the oil level. There was no warning light illuminated. The vehicle was taken to a local Pep Boys where oil was added in the vehicle and the contact drove to his residence. However, the failure persisted while driving. The vehicle was towed to the dealer where it was diagnosed that the exhaust cam gear had fractured, causing damage to the engine and other unnamed components. The dealer diagnosed that the engine, the exhaust cam gear, and the timing chain needed to be replaced, and additional unknown repairs were also needed. The vehicle was not repaired. The contact related the failure to an unknown Toyota Extended Warranty. The manufacturer was notified of the failure and informed the contact that they could not assist due to the vehicle manufactured date. The failure mileage was approximately 204,000.”

“CHECK ENGINE LIGHT, VSC LIGHT AND TRAC OFF LIGHT ON AND OFF LIGHT INTERMITTENT. AT ANY TIME THE LIGHT GOES ON AND OFF. IT IS NERVE BREAKING KNOWING THAT THE WARNING LIGHT AND THE PROBLEM CAN NOT BE FIXED BY TOYOTA. I HAVE MY TOYOTA SIENNA 2008 AND IT HAVE A VERY LOW MILES DUE TO LIGHTS SAFETY REASONS THAT CAN NOT BE SOLVED BY TOYOTA. EVERY TIME WE COMPLAIN, WE WERE ALWAYS TOLD THAT BRING THE CAR IN WHEN THE LIGHT GOES ON. THE PROBLEM IS WHEN THE LIGHT GOES ON IT WILL BE OFF WHEN WE GET TO THE DEALERSHIP. WE NOTICED WHEN THE CAR REACHED APPROXIMATELY 98,000 MILES. THE CAUSE OF THE ON AND OFF LIGHTS ARE UNKNOWN.”

“WHILE DRIVING WITH MY AUTISTIC CHILDREN THE CHECK ENGINE LIGHT, THE VSC LIGHT AND THE TRAC OFF LIGHT ALL CAME ON AND THE WHEELS LOCKED UP ON THE RIGHT SIDE AND THROUGH THE VAN INTO A DITCH. THIS IS VERY DANGEROUS SINCE THIS VEHICLE WAS MADE FOR FAMILIES. I AM NOW KEEPING A LOG AND I DO PLAN ON RETAINING AN ATTORNEY AS NO ONE HAS ADDRESSED THIS ISSUE AS A SAFETY HAZARD. *TR”
