Check engine light kept coming on and they had to replace the o2 sensors and cats

I just recently got the truck back from having both cats and the o2 sensors replaced. I drove it for about app.50 mi. and the check engine light came back on. So needless to say the truck will be going back to the dealer for it's fifth trip to have what i'm sure is yet another cat and o2 sensor replacement. The dealer has accepted to replace parts even though the 3 year 36000 mi. warrant has expired...... due to the vehicles exhaust track record. Good luck to me, ya right!!!!!!!!!!!!!!!

The fourth time at 36,756 catalytic converter and o2 sensor failure. Every time dealer has replaced all relevant parts, as per my warranty coverage. This most recent problem was not covered by my 36000 mile warranty. The dealer seeing the on going history of the exhaust problems has elected to repair it AGAIN! with out charge to me.

The third time at 35,121 mi. o2 sensor again!!

I have had multiple problems with my 1500's exhaust system. The second time was at 15,150 miles. Check engine light on again indicating 1 upstream o2 sensor faulty.

I have had multiple problems with my 1500's exhaust system. The first one at 8,062 miiles. The check engine light came on and was revealed by the dealership that the catalytic converter had failed.
