Asked by gschiavo Sep 24, 2012 at 07:05 PM about the 2007 Hyundai Sonata

Question type: Maintenance & Repair

My 2007 Sonata has 42,000 miles and I've had two 02 sensors fail in the last 2 weeks.  Warranty expired
last month and each sensor cost $275.  I feel the sensors must be defective, but the dealership says
they aren't, and in fact, the other sensors may fail too.  What would cause this to happen?

The sensor itself might possible not have failed but something else contributed to the O2 sensor to light up the check engine light. Did the dealer specify what the replaced besides the O2 sensor? You might want to take the car to a independent local mechaninc now that the car is out of warranty for an honest repair.
