What Goes Wrong
Reported failures, each from a source listed below, as of October 7, 2026.
Symptoms
- The Lexus emergency response guide says a ground-fault monitor watches for high-voltage leakage to the metal chassis while the vehicle is running; if it detects a fault, the master warning light comes on and the display shows "Check Hybrid System".

Same Electrical Spec
These packs share this one's chemistry, voltage and module count. That is a spec match only. It does not mean the parts fit each other, so check with a technician.
Warranty
Lexus's 2011 and 2017 CT 200h Warranty and Services Guides list the hybrid battery under the Hybrid System Warranty (with the battery control module, hybrid control module and inverter with converter) for 96 months or 100,000 miles, whichever occurs first.
