2019 Honda Ridgeline electrical system problems

“My wife and I had decided to empty our storage unit, so on Memorial Day we began moving everything into the garage. After five or six trips Honda, I pulled the car up beside the RV and close to the house for what turned out to be the last load. I unloaded my bicycle and nearly everything else, leaving only a few small items, and then removed the massage table from the back seat. The engine was off this entire time. That was when I noticed smoke coming from the engine compartment. At first, I thought the radiator had overheated, so I tried to open the hood, but it was too hot. I went into the garage for gloves and a fire extinguisher and tried again, but still could not get it open. Realizing the situation was getting worse and that I could not stop it there, I jumped into the car and tried to start it. To my surprise, it started immediately, and I drove it as fast as I could out to the street in front of the house. Only later did I realize that this likely saved my RV—and possibly the front of my house as well—from catching fire. We were so blessed that I was able to move the car to a safer location and no one was hurt. It was a miracle.”

“2019 Honda Ridgeline alarm started going off at random times. This is a safety concern because it causes drain on battery and could affect vehicles ability to operate . The part is the keyless entry unit located behind glove box. I had to go out to check the car in the middle of the night several times. This part has been reported and listed here under bulletin SB-21-055. Honda offered extended warranty and fixed some vehicles as reported by some Ridgeline owners. This random alarm was reported by 86 Ridgeline owners according to Ridgeline owners club. The repair cost me $957 including a $287 charge for labor- according to the NHSTA bulletin SB 21-055 labor should be .03 to .08 hours to repair - beware of over charge for labor. Courtesy Honda of Palm Harbor Fl. Offered $100 off when informed of the keyless entry unit history. I escalated to American Honda who offered nothing, not even goodwill discount. This is the keyless entry unit for bind Ridgeline and Pilots. There is a documented issue with this part (SB 21-055) it’s a safety concern considering the draw on battery power not to mention where you are when the alarm starts blaring. This part has a known…”
