I have a 2019 Honda Civic 2.0 liter cvt with 18,500 miles on the odometer. I hit a sidewalk curb going 1-2 miles an hour when I was parking. Can this cause any damage to the alignment or any suspension parts? Or is it nothing to worry about? Everything still feels normal when driving though
Suspension: no not at that speed.
But if you've got low profile tires then be extra careful. If you hit that curb going on an angle then you can scrape your rims or damage the tire. I just saw someone do this last week.
Just don't do it again or else the alignment can get knocked off
The only possible damage could be Curb Rash. Very common on Honda Accord Sport models, especially the rear wheels. Did you get the wheel protection package when you purchased the Civic?
