2013 Lexus Is

2013 Lexus IS 350C with approximately 56,000 miles experienced engine smoking on startup. The vehicle has been regularly maintained according to the manufacturer's recommended service schedule. The Lexus dealership diagnosed oil entering the combustion chamber and documented that the cylinder walls are scratched, allowing oil to pass the oil-control piston rings. Based on the internal engine damage, the Lexus dealer has recommended complete engine replacement. I am concerned that this type of significant internal engine damage at only approximately 56,000 miles could result in progressive oil consumption, loss of engine performance and potentially engine failure while the vehicle is being operated. The vehicle has not been abused or subjected to unusually high mileage and has received regular maintenance. Lexus corporate was contacted regarding the premature engine failure and a request for goodwill assistance was denied. I am submitting this complaint because I believe an engine requiring complete replacement due to scratched cylinder walls at approximately 56,000 miles warrants review to determine whether similar failures involving the piston rings, cylinder walls or oil entering the combustion chambers have occurred in other Lexus vehicles equipped with this engine.

VALLEY PLATE LEAK DUE TO THE FACT THAT TOYOTA/LEXUS UTILIZED THE IMPROPER SEALANT AND USED THE IMPROPER AMOUNT, LEADING TO THE HEAT EXCHANGER LEAKING COOLANT ONCE THE ORIGINAL, INADEQUATE SEALANT BEGINS TO DISENTEGRATE. THIS COULD CAUSE A CONDITION WHERE THE ENGINE COULD FAIL AND SOMEONE COULD GET HURT. FURTHERMORE, ALL ISFS WILL EVENTUALLY HAVE A CRACKED RH MANIFOLD ON THE #8 RUNNER. THIS CAN CAUSE A FIRE HAZARD IN ADDITION TO CARBON MONOXIDE POISONING.
