Turbocharged NX variants can experience hesitation, underboost or a check-engine light from intake leaks, sensors, ignition, fuel or boost-control faults.
How the concern should be evaluated
Check the specific engine and requested-versus-actual boost, inspect charge-air connections and evaluate fuel and ignition data before replacing turbo components.
When to contact a Lexus repair shop
