I had a local tire shop install it for me. It took 15 minutes at most. No issues at all. They actually left the car running, disconnected the old battery and hooked up the new one while the car was running. Nothing need to be re-programmed. No Active Steering Errors, kept my seat and radio settings etc. THIS IS NOT A RECOMMENDED PRACTICE. You need to be very careful as one spark during this process could cause a short in your electrical system. I found about this after the fact. But no harm was done, so I was happy. The dealerships charge way too much for the install. I was quoted $116 dollars just to install the battery. I bought the battery and had it installed for under $200 dollars. OEM Fit and quality. Be sure they re-connect the vent tube for the battery once installed.
