Like other Honda models being investigated, this 2020 Ridgeline also applies the automatic braking system with on vehicle directly ahead (nearest vehicle is 2 lanes over). The date below is today, but events were in the past
1st time we were driving on a mountain highway at 70 mph, when the truck self applied the brakes and we were nearly rear ended by another truck, there was no vehicle directly in front of our car to cause this to happen. I took the truck to the dealer as soon as we returned home, they found nothing wrong! A few weeks later this happened again for no apparent reason however thus time no other car was near enough to cause a incident. I returned the truck to Honda Service after 1st calling Honda USA and having them document our concerns. Once more they could offer no reason or correction. This continues to randomly happen to thus day. I have 2 service documents to back up both times I returned to the dealer.
ON 12 OR MORE OCCASIONS THE TRUCK BRAKED FOR NO REASON. NOTHING IN FRONT OF ME. IT'S BEEN TO THE SHOP 3 TIMES FOR THIS. I HAVE DONE RESEARCH ON THIS PROBLEM AND FOUND OUT HONDA HAS SEVERAL LAW SUITES ON THEIR CMBS SYSTEM GOING BACK TO 2015. SO WHY HAVE THEY BEEN ALOUD TO KEEP THIS SYSTEM IN CARS AND TRUCKS.
Since new vehicle''s Forward Collision warning stating "BRAKE" will occasionally appear for oncoming traffic. Vehicle has attempted to brake as well. There is no fix from Honda Motor Co. Vehicle also has an issue with automatic high beams (which has no current fix) which has been filed separately.
