Today I experienced a serious problem with my brand new RL. After driving for 5 minutes at 35 mph, the dashboard instrument panel lit up like a xmas tree, and error messages began displaying on the multi-display screen. All messages displayed in amber and were preceded by a warning tone. They began with ACC Adaptive Cruise Control Problem, then AWD All Wheel Drive System Problem, followed by the VSA, CMBS, and others. The messages were constant and would loop continuously. The vehicle still seemed to drive normal, but I had no way to verify that the various systems were working. Blind spot monitoring still worked on both sides. I purposely tested the LKAS feature and it did NOT work. Soon I reached a location where I could pull over. While attempting to shut off the vehicle, it took 4 presses of the start/stop button to turn off the engine. A single push started the engine, but the error messages began displaying again. It seemed like for every instrument panel icon illuminated, a corresponding warning was displayed in the multi-display screen. I contacted the Honda dealership and they told me to bring the truck in. Drove into the repair bay, left the vehicle running so they could see the looping error messages, showed them the attempts to shut off the engine, then restarted the truck so the errors could be viewed. A technician said it might be the battery, or the start/stop button. They didn't know for sure b/c they had never seen anything like this before. I voiced my concern that the truck was brand new, with 463 miles logged. I also engaged in a conversation with my salesman explaining my disappointment, and the need for something to be done to make amends in some way. I left the truck and returned home in my wife's car. Soon the repair guy called and said after they hooked up the truck to the computer, they were able to clear all the messages, but two remained. The wheel sensor and speed sensor. Nothing had displayed on the dash with re: to these conditions. The tech said they are messages that appear in their diagnostic testing. Replacement sensors were ordered and be would over-nighted to the dealership. They will call Friday to let me know if these sensors were the culprits. So now I'm left to fess up to the wife that I may have been premature in buying too early as many on this forum had warned. My VIN was 1691. I will post the resolution when it happens. Damn!
