“My vehicle's warranty which I purchased separately had just expired but I still went back to dealer as the noise I had reported to them under warranty was now more apparent. Turns out it was due to broken off exhaust header bolts.now I am out of warranty, dealership will not fix. I have 1 broken on drivers side and 3 on passenger side. Now my check engine light is on showing an oxygen sensor failure or catalytic converter. After researching the internet this problem is affecting thousands of people. Something needs to be addressed !!”
