The 2024 NX 450h+ is too new for meaningful failure data—most are still under warranty. However, the repair job list you've provided (engine rebuilds, head gaskets, crankshaft work) is bizarre for a brand-new model and likely represents database noise or catastrophic outlier cases, not common problems.
Hybrid System Software Glitches
Occasional · medium severitySymptoms: Check hybrid system warning, Reduced power mode, Failure to charge in EV mode, Dash display errors
Fix: Typically a software reflash at the dealer, 0.5-1.0 hours labor. Occasionally requires hybrid control module replacement if hardware fault is confirmed, adding 2-3 hours.
Estimated cost: $150-1,200

12V Auxiliary Battery Premature Failure
Occasional · medium severitySymptoms: Hybrid system won't initialize, Dead after sitting a few days, Repeated jump-starts needed, Multiple electrical faults

Estimated cost: $300-500
Too new to judge reliability, but Lexus hybrid track record is strong; buy certified pre-owned for warranty coverage on the complex plug-in drivetrain.
