Hello - I had three frustrating scenarios crop up this year, here's what I learned...

CAR DETAILS: 2018 Honda CR-V LX Automatic

1 - Sudden sequence of error messages flashing when starting my car: Road Departure Mitigation System Problem, Collision Mitigation System Problem, Adaptive Cruise Control Problem, and the Brake System light is illuminated.
Car didn't show any change in performance, took it back to the Honda dealership for diagnosis. Turns out the Wave Radar Sensor needs replacing - cost of unit and labor estimated at $3000. Found replacement parts online for about $400, but the YouTube vids show you have to remove a lot of flashing and the bumper to access the parts. I didn't attempt it. Dealership says there is no safety risk to operate the vehicle, but features like "lane keeping assist" (LKAS) and other radar-related features will not work.

2 - Car would not start - sequence of about six different error messages flashed on the display: All Wheel Drive System Problem, Vehicle Stability Assist Problem, Tire Pressure Monitor Problem, Hill Start Assist Problem, Electric Parking Brake Problem and others... this was a battery issue. Repair shop told me that the Honda CR-V uses an unusually small battery - and since there are a number of electric functions monitoring and performing upkeep (even when car is off and parked, ever hear it humming in your garage?), the battery gets A LOT of use. This leads to an overall shorter lifespan. Buy the best battery you can and you'll save yourself some frustration down the road.

3 - Tire Pressure Monitor Problem (TPMS) - This one is a quick fix - just check your tires and make sure they're not really losing air. If you're feeling good about their ability to hold air, get into your on-screen control panel and use the TPMS Calibration option. That'll just reset the sensor to accept the existing tire pressures as "normal." A sudden increase or drop in temperature can cause this, and I wind up having to "recalibrate" 2-3x each year.

All-told, this might be my favorite of the cars I've owned. But sometimes, the new tech "features" they jam into these cars only deliver more headaches. Hope these explanations will save a few people from banging their heads like I did! Good luck out there!

What were the end results of number 1 and number 2?
#1 - I decided not spend the $3k required to replace the radar. I'm happier driving without all the auto-assist features anyway. Dealer said it was no risk to just clear the errors every time I get in the car (although it is obnoxious).

#2 - Swapping the battery cleared all the messages.
