One problem related to o2 sensor has been reported for the 2007 Chrysler Sebring. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Chrysler Sebring based on all problems reported for the 2007 Sebring.
The car had a new set of spark plugs and a transmission service at 60,000 miles. The car was being driven at freeway speeds when it lost power and then was stuck in second gear. It was towed to a Chrysler dealer where they serviced the transmission believing that was the problem, because the obdii system reported no current or stored error codes. They returned the car and stated that it was running rough and should have a tune up. The car was driven about 180 miles at freeway speeds when it again lost power and was stuck in second gear. This time the car was driven along the shoulder to the next off ramp at which time the check engine light came on. The car was towed to another Chrysler dealer where the obdii codes showed that the catalytic converter and an oxygen sensor had failed. The dealer replaced these items. Fuel economy dropped from about 30 mpg to about 23 mpg. The local dealer looked into this problem but said that the obdii system is reporting no current or stored codes so there is nothing they can do per the factory, they also have noted that the engine is running roughly. Chrysler was contacted about the problem and agreed to refund the cost of the transmission service because it was not the problem. I mailed all the copies of the requested paperwork to them but they never responded back and have not paid.
