I Need Help

Asked by Bula1987 Jan 15, 2018 at 02:07 AM about the 2010 Chevrolet Traverse 1LT AWD

Question type: Maintenance & Repair

We have a 2010 Chevy Traverse Lt
AWD 102,000 miles on it. I was driving
and noticed a whistling, hissing sounds
coming from the car it was very quiet
at first. Then shorty after it got loud & it
seemed like the car didn't have
momentum like normal. Upon Taking
of from a red light. I knew something
was not right. Drove slowly till I could
find a spot to park it. Once my husband
had a look underneath there was
steam hissing out of a small hole in the
Flange Gasket in the front of the
exhaust we're it goes up to the engine.
We thought it would be a easy fix.
While taking the two bolts out one
broke off & what was weird was it was
welded. To make a long story short he
bipassed & cut that area off & used
straight pipe ect. Got it back on there
no more hissing thought problem was
solved. As he went to test drive it he
heard a Grinding noise coming from
somewhere as the RPMs went up, it
shifted gear & stopped.. Right now we
have been racking our brains trying to
think positive & hope nothing went into
the engine from the exhaust. Please
help.

Sounds very similar to what just happened with my daughter's 2011 Traverse... Not good! The entire engine has to be replaced. This is very common in the Traverse..Google it.
