2 front oxygen sensors broke at the same time?
The check engine light up and dealer service had been visited. Just like to know: Could it possible that 2 fron oxygen sensors broke at the same time?

How did they fail? Contamination or burn out? How many miles are on them? How is your battery? The O2 sensors are heated, and low battery voltage will make them appear bad.
Did you see any OBDII codes? Have you used any chemicals in the gas tank or sprayed into the air intake?

Thank you for your questions. I found the "check engine" light on and brought the car to service. The readings showed they code P 207F- 001 G3/3 (left o2 sensor, before TWC) againg, correction variable, P 207F- 001 G3/4 (right o2 sensor, before TWC) againg, correction variable. Delay time too long (P-2096)
My c240 has 129000 miles on it. I did not use anything unless they pour something into my tankin the last maintenance service. I did not check my battery for the last 3 years. Maybe I should do it first? Thank you again and waiting your advices.
