Henry Anderson - Schaumburg route. Toyota and Lexus hybrid battery calls only. No oil changes, no brake menu, no guess-and-swap work. Typical visit: the owner reports a red triangle, a sudden MPG drop, or a Check Hybrid System message after the car has been running normally all week. Henry starts with the HV pack, not with a parts quote. Module pairs are compared under load. Fan activity and temperature spread get checked. If the traction battery is the cause, the replacement plan is written down before the install begins. Most appointments stay near Schaumburg, Arlington Heights, Palatine, Elk Grove Village, and the I-90 corridor. Prius and Camry Hybrid jobs are common; Lexus RX and ES hybrids show up often enough that Henry keeps the safety routine the same every time. The rule is plain: prove the battery problem first, then replace the pack cleanly.
