Hybrid battery testing, repair and replacement
Get your hybrid back to its real fuel economy and stop the engine from running all the time. We test the hybrid battery cell by cell, check the cooling fan that our heat clogs, and check what the factory still covers, since hybrid batteries often carry longer coverage than the rest of the car. Then you get a written price and real options.
Hybrid battery
- Test the hybrid battery under load and read the voltage of every cell group, so you know if it is one bad module or the whole pack
- Check the factory hybrid battery warranty by VIN before we quote anything
- Clean the battery cooling fan and filter, which pulls cabin air through the pack and clogs with dust and pet hair
- Replace single modules when the rest of the pack is healthy and the price makes sense
- Replace the whole pack with new or remanufactured units, with the price of each in writing
- Check the inverter, its coolant pump and the high-voltage cables that connect it all
- Clear hybrid system codes and confirm the repair on a road test
Signs you need this
- The check hybrid system or battery warning is on
- The gas engine runs more than it used to, and fuel economy dropped
- The battery gauge jumps from full to empty and back in a few minutes
- The car feels weak pulling away or on hills
- A loud fan noise from behind the rear seat
- The car will not start or goes into limp mode
The first step is a warranty lookup, because hybrid batteries are often covered longer than people think and we want the manufacturer to pay if they should. If it is out of coverage, you get a written price for each option before we start. Tax is on parts only. You choose the warranty on the job: 90 days, 1 year or 2 years.
