. Over the last 7 months I have had my Sonic in four times for the same continued problem. I understand that it an intermittent problem and hard to catch it in the act of occurring and the service staff has been very attentive to looking into it, but I am beginning to get concerned as to whether this will ever get solved and when it may become a more severe problem. But let me first explain the problem. Usually in the morning as I am driving to work my display does the following: the LED display area flashes brighter and the speed, trip mileage, odometer disappear and return instantly, at the same time the Tachometer drops to zero, the LTP indicator light, and the anti sway light all flash on then off. This happens several times over a one to two minute period. When it stops the airbag light is on and stays on. It has also once disabled the AC (cooling only, which reset when the car was shut down and restarted), and it also seems to affect the speed of the turn indicator.
I have had the Service Dept. look at it several times and they have twice changed the Negative cable on the battery, as the computer throws a low neg. voltage code (DIDN'T FIX IT). Plugged and replugged every cable to the dash area to reseat the connections (DIDN'T FIX IT). Changed the BCM(body control module) (DIDN'T FIX IT).
I don’t know what to do now but I'm worried it may progress and cause a more fatal failure some day. So far it is still under warranty, but I'm afraid it may continue beyond the warranty and never get solved.
