I had taken my camaro to the dealer and to another shop but no one could figure it out. I bought 3 battery’s total which they said would fix the problem. NOPE. I took it to Dealer Alternative and with in 5 hours they found the problem. They told they may have to replace the computer bet they would do their best to keep the cost low. And they did. Also the service advisors are very professional and informative. They called me on every step of the repair. This is my go to shop now.
