Frozen Mufflers for Jeeps

Feb. 23, 2021

The customer might describe a crank/no-start condition in freezing temperatures.

This bulletin applies to 2015-2020 Jeep Renegade and 2017-2018 Compass vehicles. The customer might describe a crank/no-start condition in freezing temperatures. This condition might be caused by condensation freezing in the muffler assembly. Check to see if there is a weep hole on the end of the muffler. If no weep hole is found, use a 3mm (1/8-inch) drill to drill a hole no deeper than 1 inch into the bottom corner of the muffler.
