Identical to complaint #10114548
my event happened January 6, 2005 with less than 10,000 miles on vehicle. Now, at 35,750 miles, I have O2 sensor problems on a routine basis(3rd sensor on order from dealer right now). I am very concerned that these problems will continue past warranty, I have little faith in this vehicles safety and performance -every day I cross my fingers that nothing else goes "brakes" while driving with my 2 small children. This needs to be investigated.
