What owners wrote
“AC is NOT working and it is a SAFETY ISSUE as drivers can have HEAT STROKE and other heat medical issues especially with medical conditions like me. This is the car I am driving to for everything. I saw a lot of complaints online with the same AC issues related to Honda even under 50K miles only.”

“When driving and removing foot from the acceleration pedal, allowing my car to slow without hitting my brake, I have noticed a loud humming/vibration around the 40 mph speed. It is very dangerous because it distracts my driving. I have tried powering off radio and ac/heater, rolling windows down and opening sunroof. Nothing seems to stop the noise.”
