Suzuki Forenza owners have reported 2 problems related to o2 sensor (under the electrical system category).
Oxygen sensor was bad 3 months after buting car, both airbags in dash are defective. Sensors are lighting up and it says can deploy at any time get car serviced. My dealership acts like they don't want to help me.

I own a 2006 Suzuki Forenza and have had numerous problems with this car. Since purchasing new in 2006, I have had the gas gauge, gas tank, radio, center console, front door handles & catalytic converter replaced. The factory tires went bad within a year, and because it is an odd tire size cost over $400 to replace. Currently the check engine light is on stating there is a problem with the catalytic converter which was just replaced about 3 months ago. I left the car overnight at the dealer & got a rental car (which cost $75) and the dealer and Suzuki tech support can not figure out why the catalytic converter error continues to show up. The power steering light is also on & I was told that it requires a sensor - not covered by warranty - that will cost over $300. I have had a problem with the engine jerking and slipping gears on acceleration. It would also stick in neutral or not change gears and hesitate to the point of moving very slowly. I was told this was an oxygen sensor which cost me over $300 to replace. I have had this problem once since. The struts - front and back - also need to be replaced which is a $1200 repair because they are leaking. Currently both front door handles are broken causing me to have to open the windows to open the doors. I have had them replaced once before under recall, but now it will cost over $200 a piece to replace. I didn't even know there was a light to indicate that the daytime running lights were working until it just appeared one day. The daytime running lights indicator won't stay on - it comes on, then goes back off. I think Suzuki needs to make good on these cars because there are so many problems.
