Honda
Ridgeline

The contact owns a 2018 Honda Ridgeline. The contact stated that while driving approximately 50-55 MPH on I-40 Westbound to I-25 and making a turn in a construction zone, the passenger’s side air bag deployed without warning or impact to the vehicle. There were no reported injuries. The air bag control message was displayed after the failure. Two days later, the system indicators produced a failure with the road departure mitigation, collision mitigation, trailer stability control field assist, vehicle stability control, power steering, air bag system, and adaptive cruise control. The brake system warning light was illuminated after the parking brake was released. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was approximately 56,850.

My check engine light came on and within minutes there was a loud noise, smoke and my vehicle lost power. I was on Hwy 20 returning to Boise, ID from Bend, OR. Luckily this occurred just as I had cell service since I was without cell service just before this occurred. This happened in the evening on Nov 2, 2025. I had just had it serviced for regularly needed maintenance as recommended by Honda. 10/20/2025 I spent $2274.28 on service at the Honda dealership. Service included transmission service, oil change, strut service, replace front struts, wheel alignment, and resurfaced front rotors. I've had all my regular maintenance handled timely and at the dealership. I was 75 miles from the dealership and had to spend $521 to have it towed to the dealership. My truck lost power so fast after the check engine light leaving me on the side of the hwy 15 miles from the nearest town as the sun set. I waited in the dark for a tow truck. So grateful that I had regained cell service to call for help. The truck is currently at the dealership awaiting resolution. Dealership notes: engine oil leaking all over the engine assembly, used bore scope and inspected behind bank 2 catalytic converter and found a hole in the engine block. Recommend replacement of the short block with new heads or replace the engine. Service department suspects the problem a connecting rod bearing failed. We've had multiple phone and in person discussions regarding the matter as we try to resolve this. There is a recall on the 2017 and 2019, but not the 2018. There is an open probe regarding the 2018.

Multiple warning lights appeared and remained illuminated on my dash, all related to safety features (LKAS, ACC, CMBS AND ROAD DEPARTURE). The problem was confirmed by Capitol Honda Service Department. The vehicle was scanned and stored DTC was found at INTEGRATED DRIVER SUPPORT SYSTEM. U3000-49 MULTIPURPOSE CAMERA UNIT INTERNAL ELECTRONIC FAILURE. The DTC was set as hard code, unable to clear. RECOMMEND REPLACING MULTIPURPOSE CAMERA AND PERFORMING CALIBRATION. The estimate I was initially given for the cost of the repair parts and labor was close to $2,000. The repair was necessary because the inoperable safety features directly affects my safety on the road as well as the safety of others.

Infotainment system have a black screen

Engine started making a knocking noise on start up. Got progressively worse for the next 3 days before I stopped operation. Dealer states "engine has a rod knock likely due to a spun bearing". No warning lights or messages displayed.

Had a clacking noise that got louder depending on RPM's, scheduled a visit to the dealer same day to also take care of a B1 maintenance notification that appeared 2 days prior and on the way to the dealer from work the same day the clacking noise started, the engine light started to flash and then within a few seconds there was a complete loss of power to the accelerator and the RPM's dropped to zero; Had to pull off the interstate in a construction zone where there was no shoulder and just on a dirt slope. When towed to the dealer, dealer stated the engine had suffered Rod bearing failure and there were metal shavings in the oil pan. The car is available upon request, it is at the dealership at the moment and I am scheduling it to get an engine replacement. I contacted Honda because this is a Honda Ridgeline 2018 and they denied my request for goodwill consideration, I stated that this is surely apart of the ongoing investigation "RQ24013" as it sounds extremely similar and there have already been recalls issued under "23V-751". They stated the vehicle was not taken to dealers for maintenance before I bought the truck 5 months ago and that the truck has too many miles at 90k miles so therefore they will not help. This is an extremely dangerous car to own when the engine can die on you like that after only 1 day of a clacking noise, if you are on a bridge with no shoulder or like me in a construction zone, you will be a foot away from traffic moving at 70+mph next to you and stranded with no Hvac system. I was personally in my car for an hour and a half in the deep south in the middle of summer, so 90+ degree temps without A/C. Also I bought this from Carvana who did a "150 multi-point inspection" of the car and missed this and refuses to help in any way, they just stated "Oh sorry to hear that" and then closed the chat, so don't buy from Carvana, they won't help you at all.

The truck has a hard/rough shifting between 2nd and 3rd gear in an automatic transmission. No dash light indicating anything wrong with the engine or the transmission.

KEYLESS ACCESS CONTROL UNIT PART NUMBER: 38320-T6Z-A31 The vehicle headlights came on and dash lights flashed on and off. The alarm would also go off and on. This causes the battery to drain as well. Also I know of several other Honda Ridgeline owners who have had the same part failure
