Example complaints

“As I was driving in my yard I happened to bump the ignition key and the motor cut out and died. This caused me to not be able to turn and avoid bumping a post causing some body damage, but I was able to avoid hitting my friend in the yard because he had moved from by the post a minute earlier. I have had one more time with this problem, but not had a problem since, but I am now experiencing an occasional rough running engine. Could this ignition switch on this year vehicle need to be recalled also?”
