I have a 07' Toyota Camry (bought new) with approx. 60k miles on it (mostly highway). My driving habits are sedate. I haven't abused the car and have only taken it to the mountains once. The roads that I drive are relatively free of potholes, but there is one tall hill that I have to climb daily during my commute. I brought my car in for routine service and was told that all 4 struts were leaking. Is this unusual given that all 4 seem to have been affected and I do not abuse my car (cruise control set at 65) during my drives? Has anyone else experienced the same problem with their Camrys?
