Customer Complaint/Technician Observation: The engine/exhaust
ticking/rattling/ringing concern customers may report on the TRX is inherent to the
exhaust manifold and catalyst design that ultimately helps achieve the 6.2L supercharged
engine's horsepower and torque levels. The high level of exhaust flow and pressure,
which the exhaust system is designed to withstand under the harshest of conditions,
causes this metallic sound especially during a cold start-up. This sound is amplified by
the ground clearance and height of the TRX in comparison to other vehicles with the 6.2L
supercharged engine. It is considered a normal operating characteristic of this vehicle.
