On certain vehicles equipped with a 1.6L engine, the cylinder head cup plug (freeze plug) may become dislodged, resulting in a significant loss of coolant which could cause the engine to overheat. Under certain circumstances, water in the remaining coolant mixture may vaporize, resulting in a higher concentration of glycol (antifreeze). A high concentration of glycol could become flammable and, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the cylinder head. If the cup plug is dislodged or leaking, the cylinder head assembly will be replaced. If the cup plug is not dislodged or leaking, a wicking sealant will be applied to the plug and a cover plate will be installed over the plug with adhesive.
On certain motorcycles, in extreme cases, engine heat could cause the exhaust butterfly Bowden cable to melt or burn, which could cause property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will replace the cable with an updated design.
On certain motorcycles, a porous engine crankcase could allow oil to leak from the machined area at the starter mounting point and pool on top of the crankcase. The oil could then spill onto the rear tire, which may render the vehicle unstable. This could result in a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will apply an epoxy sealer to the affected area of the engine crankcase.
On certain vehicles, the turbocharger turbine wheel may have been incorrectly manufactured and could fail. Turbine wheel failure would result in a noticeable decrease in vehicle performance. Continued vehicle operation could cause the turbine shaft to also fracture. If the fractured shaft moves out of a bearing, oil may be drawn into the exhaust system, which could result in a fire causing property damage and/or personal injury.
On certain vehicles, the engine crankshaft may have been incorrectly manufactured and could fail. If this occurs, the engine could seize, suddenly rendering the vehicle inoperable. Loss of vehicle propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will either repair or replace the engine, depending on the vehicle owner's preference.
On certain motorcycles, the connecting rod bolts could loosen and separate from the connecting rod. This could cause the rear-wheel to lock-up if the engine fails and seizes creating the risk of a crash. Additionally engine failure may also cause oil to leak in front of the rear tire which may render the vehicle unstable. These issues could result in property damage and/or personal injury.
Safety Risk
No risk description available.
Remedy
Dealers will replace connecting rod bolts and apply a thread-locking agent to the bolts.
On certain scooters, the ignition control unit may not function correctly during engine starting, which could cause an engine backfire into the airbox. This could result in a vehicle fire causing property damage and/or personal injury.
