2012 Chevrolet Colorado Engine Problems

Your truck won't start when the security light is flashing. Disconnecting the negative battery terminal for 10 minutes allows it to start again. Using the remote lock causes the truck to fail to start about every third time or more frequently, so you've stopped using the remote. This happens several times per week.

You've been hearing an abnormal whistling noise from your engine that has gotten worse over several months. A mechanic diagnosed that your exhaust manifold has cracked down the middle, which is causing the noise. The exhaust manifold will need to be replaced to fix this issue.
