“I called my local Lexus three times prior to june, 2012 regarding lights suddenly illuminating on the dashboard. I had a recurring issue where the check engine and vsc warning lights would illuminate. Each time the customer service agent told me that the lights would go off when I refueled. Three times the lights did go off (after several days), but once I had to have the dealer reset them. The most recent occurrence resulted in the dealer telling me I needed the air fuel and air flow sensors replaced, a repair which cost over $750.00. …”
