Wow, I am shocked at the poor reviews. I only have a couple experiences, but they were not for anything all that major. When I changed the battery on a BMW it lost all the programing for the windows, etc. Called BMW and they said it would take 8 hours to re-program and $500.00. THey told me only a BMW battery would work in the car. I bought it from Autozone and JCI is the same mfg and same specs for half the price. The BMW forums confirmed that the service dept story was a crock. Jim, said it takes a couple hours tops and the programmer does all the work way less than $100 later all was excellent.\r

Not a problem with Jim's but find it really poor engineering that a car's accessories module would have to be re-programed after a battery installation. But many confirmed that was the case on a certain model and year range.
