Hybrid RX vehicles combine gasoline and electric drive components, with cooling and electrical architecture that differs by generation. Reduced performance or a hybrid warning may be accompanied by cooling, 12-volt or control-system concerns.
How the concern should be evaluated
Identify the exact RX hybrid variant, evaluate the 12-volt system and relevant diagnostic data, and determine whether the concern involves conventional cooling or high-voltage equipment. High-voltage work requires qualified personnel.
