Many Chevrolet Trailblazer owners and drivers report a vibration when the vehicle has come to a stop, when backing up, slowing down, or for a split-second while accelerating from a stop.

This is commonly associated with the engine mounts.

Engine mounts are formed from composite rubber materials that are very tough, yet absorb vibrations very well. They separate the engine from the chassis, and reduce the vibrations caused by thousands of combustion events every minute.

When the rubber degrades over time, then engine will crush the rubber mount, become loose, and the vibrations are both amplified and transferred more easily to the chassis.

Please note, if the check engine light is on and these vibrations are present, the issue could be due to poor running conditions, and the vehicle should be inspected and diagnosed.
