One problem related to front suspension control arm has been reported for the 2004 Honda Insight. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Honda Insight based on all problems reported for the 2004 Insight.
Control arm cracked and split while pulling out of a gas station. This vehicle does not have an upper and lower control arm, only lower (made of aluminum for weight reduction). If this happened on the highway, I would likely have veered off the road and be seriously injured, or even worse, dead. This should never have happened.
