2019 Honda Ridgeline Electrical 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 history of being faulty, has been documented with NHSTA (SB 21-055) Ridgeline Owners Club has 86 different entries for that part alone and could effect lighting and driver assist functions considering the draw on battery power. The alarm goes off without warning or indication and happens randomly.

A failure with the "keyless entry/TPMS control unit" caused my alarm to go off randomly. Alarm would go off at random times, draining the battery & leaving the truck unable to be started. Also, while going off, the truck could not be used/controlled/started. Honda replaced the defective part, at my cost, without a manufacturer discount. This happened randomly from when the vehicle was about 2-3 years old, then reappeared at around 4-5 years. Honda knows about this problem and issues a TSB for it, TSB 21-055.

There was a following problem. The car began to turn on the ignition itself. It does not matter if the keys are inside the car or far away from it. This leads to a complete discharge of the battery. May trigger an alarm if the car is closed. Flashing malfunction indicators. A couple of times it was difficult to turn off the car. After pressing the start button to stop the engine, the engine continued to run. After repeating the attempts several times (4-5), the engine stopped. Also had trouble starting the car several times. The starter worked but the car would not start. Disconnecting the battery and connecting it again solved the problem and the car started. The car was taken to the dealer where it was diagnosed that Keyless access control unit is failing. After replacing the unit and at the moment the car is working as it should.

Honda dealership told me to bring my vehicle in for NHTSA 22V867. They checked parts department and told me they had ample parts in supply. At the dealership I was told the wiring harness was inspected by them and was fine and would not be replaced. I was provided an invoice that stated “recall performed”. The service manager explained they do what Honda tells them, not what the NHTSA says. I inquired directly to Honda and they verified they do not do what the NHTSA says, only what Honda says. I would like the wiring harness replaced per the recall, per the ample supply Honda told me they have. The dealership verified twice to me they have an ample supply.

Incident

Nov 19, 2022

The 2019 Honda Ridgeline truck has a tailgate that opens and closes vertically as well as from right to left with a hinge on the drivers side. The action appears to cause the wire from the back up camera to chafe causing a short circuit. Shortly after my 36,000 mile warranty expired by back up camera began to fail. Now the backup camera does not come on when put into reverse but the whole display screen (GPS, Audio, etc) does not come on unless the tailgate is opened and closed repeatedly. This presents a safety hazard as vision behind the truck is very restricted when backing up. My Honda dealer said that there is a TSB for this problem but no recall has been issued.

Incident

Apr 8, 2022

The backup camera stopped functioning due to a wiring defect. The backup camera is installed in the tailgate and wires go between the tailgate and the body on the driver's side. Due to a design defect, these wire are prone to wear, pinching, and being cut during normal operation of the tailgate. The copper in these wires on my truck is exposed and some wires are cut resulting in the backup camera no longer functioning. This creates a safety hazard for both the driver and other people, vehicles, etc. when the car is being backed up. This issue is being investigated on 2017-2018 Honda Ridgelines (NHTSA Action Number: PE22001) but is also occurring on 2019 models which are not currently included in the investigation. This problem first occurred on my truck less than one month and less than 1000 miles after the warranty expired.
