Tire pressure monitoring system comes on. Tire pressure is exactly 34/35 PSI as door panel advises. Reset the TPMS system to fix the warning. Also, after driving 100 miles, the cruise control, lane keep, & collison mitigation system failed. Had to stop car, turn it off, and restart to get warnings to disappear
Keyfob range reduced drastically used to be able to remote start my car from over 200ft. Now I can't even do it over 30ft. Even one of the sale men said it was a problem because he was able to start his own Civic from over a 100ft.
Electrical fire within the driver door. A fire started while vehicle was parked outside and off at mall in toledo, ohio. Weather had been rainy. Came out to vehicle and the inside was filled with smoke.
2018 Honda Civic - ex-l infotainment screen (radio, heat, navigation system, A/C, etc controls touchscreen) will flash off and on while driving including during backup camera and navigation system use. Issue is intermittent and not predictable.
Honda Civic 2018 manual transmission. Bumping the keychain with my knee can rotate the key in the ignition turning off the car while driving. I have a standard size key ring with a couple car keys and work/home keys. They don't hang down very far but do so far enough to contact my knee when driving.
