How much does it cost to replace a battery in a Lexus RX400h?
The cost to replace the battery in a Lexus RX400h hybrid vehicle can range from $1,000 to $6,000, depending on the specific battery and labor costs involved. The RX400h uses a high-voltage nickel-metal hydride (NiMH) battery pack that is essential for the hybrid powertrain, and replacing this battery is a significant expense for Lexus owners.
Factors Affecting Lexus RX400h Battery Replacement Cost
Several key factors influence the total cost to replace the battery in a Lexus RX400h:
- Battery Type and Capacity: The RX400h uses a large, high-voltage NiMH battery pack, typically ranging from 288 to 345 volts. Replacement battery packs from Lexus can cost $3,000 to $5,000 or more, depending on the specific model year and battery capacity.
- Labor Costs: Replacing the battery pack is a complex process that requires specialized tools and training. Labor costs from a Lexus dealership or certified hybrid mechanic can add $1,000 to $2,000 to the total replacement cost.
- Battery Warranty: Lexus provides an 8-year/100,000-mile warranty on the hybrid battery, which can help offset replacement costs if the battery fails within the warranty period.
- Aftermarket Options: Some owners may be able to find lower-cost, refurbished or remanufactured battery packs from third-party suppliers, which can reduce the overall replacement cost.
It's important for Lexus RX400h owners to be aware of the potential battery replacement costs and to plan accordingly, as this can be a significant expense during the vehicle's lifetime.
