Save Money on Hybrid Error Code Diagnostics
If you have a light or lights lit up on your dashboard, don’t start out at the dealership for a diagnostic report ($79 to $129) that your local auto parts store can provide you for FREE. For example, stop in any trusted auto parts store and ask them to put a “scanner” on your car. They will do this for FREE and give you any trouble code(s) that your car has.
Below, we have listed some of the more popular codes that come up on hybrids. The check engine light needs to be on for a 'major issue' to be active on the vehicle and codes may not be able to diagnose the issue if the light is not on. If you have any hybrid battery failure, the dealership is once again going to be a very expensive option (hope you are sitting down….$3K to $5K)! This is for a new replacement hybrid battery that only comes with a 1-year warranty.
Hybrid Battery 911 is here to save you thousands of dollars by coming to you and installing a fully revitalized hybrid battery for around one-third of the cost AND a written limited lifetime warranty.
