Check engine light came on. Dealer diagnostic report showed a failure code of p0136 oxygen sensor malfunction. Dealer advised that sensor should be replaced at a cost of $230. 00. If part was not replaced the engine or emissions system could be damaged, and the car unsafe to drive due to possible failure while driving.
Charcoal canister failed at 13058 miles. Parts and labor under warranty, however, out of warranty cost would have been at about $500. Known issue for Toyota as service bulletin issued. Dealer recommended to purchase extended service plan to cover component after original warranty expires. Parts and labor should be covered for this component after original warranty expires as issue is known to Toyota and has failed in enough new cars to issue a service bulletin. Faulty charcoal canister will cause a no pass on smog check for California and will pollute the environment until replaced. Thank you.
