O2 Sensor

Our 2005 Elantra with 35k on it... had the Check Engine light come on...we
had the code pulled..Faulty O2 sensor...Is the sensor going faulty at 35K
pretty standard? and is 75$ for the Bosch O2 sensor a good price/ Thanks!

 

No, most sensors will go well over 100k, but stuff happens.

Not covered under warranty?

 

I didn't know sensors were covered under warranty? Are they?

 

Should be covered under the 5 year/60000 mile provisions below
http://www.hyundaiusa.com/global/warranty/warranty.aspx
Covers repair or replacement of any component manufactured or originally
installed by Hyundai that is defective in material or factory workmanship,
under normal use and maintenance.

 

To my knowledge, O2 sensors are 5/60 only. 8/80 covers ECM, Converter, an
not much else

 

HyundaiTech once said that O2 Sensors "may" be covered under the 8YR/80,000
emissions warranty. Has anyone had one replaced under warranty between
50-80,000 miles?
Come back HyundaiTech, we need you.

 

As far as the warranty, not sure. However, you can go to
autopartswarehouse.com and find the O2 sensor cheaper (or less expensive)
than buying it at either Hyundai or a local parts house.

On my sister's 99 Elantra it needed to be replaced at 55k miles.
