2018 Honda Ridgeline problems

ENGINE

The vehicle was being driven under normal highway conditions while towing a boat within the vehicle's rated towing capacity. The driver observed the oil pressure warning light illuminate and continued driving normally for approximately 20-30 minutes, at which point the engine lost power and stalled. The vehicle would not restart. Upon inspection, engine oil and transmission fluid were both found at proper levels with no signs of contamination, and the crankshaft was confirmed to be fully seized (will not rotate by hand). There was no prior knocking noise or warning sign before the oil light illuminated. The safety of the driver was put at risk due to the possibility the bearings could eject from the engine. The engine seizure has been confirmed by Right Honda, 7875 E Frank Lloyd Wright Blvd., Scottsdale, AZ 85254. The vehicle was inspected by them and they produced a diagnostic.

UNKNOWN OR OTHER

I had been hearing a ticking or clicking sound from the engine. When I brought it to a Honda dealership that I had used about a year ago for the 100,000 mile maintenance, I was told that the truck had a rod bearing failure and that I needed a new engine. I was told that if I kept driving it as is, that I could have catastrophic engine seizure without warning at anytime. This is a disaster waiting to happen. I saw that the same part on both the Ridgeline models of 2017 and 2019 had been recalled in 2023. The truck only has 110k miles and I have faithfully had routine maintenance. For an expensive $9,500 engine to fail at only 110,000 miles is not right. I will try to upload a picture of the invoice in a separate email. I hope this information will be part of the second investigation of the initial recall and also the present lawsuit against Honda in the state of California, thus sufficing as more evidence that the 2018 Ridgeline should be included in a Second Recall.

ENGINE

Catastrophic Engine Failure. Reported to NHTSA on 10.11.24 for Recall 23.097. Investigation (RQ24013) which no issues were allegedly determined. Now a new investigation has opened PE25008: We had our engine replaced for a used one and are concerned that this engine still has the issues realated to Recall 23.097. Called Honda to ask if they can confirm whether or not this used/salvaged engine had been checked to see if it has rod bearing issues related to Recall 23.097 or was from a vehicle that was related to the recall. They said they had not. Furthermore, we provided the motor serial number so they can check and they said they were not able to. They have systems in place to quickly cross reference VIN and motor serial numbers, so it was surprising they would not be able to provide this information. Furthermore, why would Honda not have systems in place to ensure they are not installing a faulty motor given the absurdly expensive pricing for a used unit. Our families life was at risk previously with the first engine failure and now it could be again, and this was their response.

ENGINE

Truck only has 40,500 miles. Was driving down road and made a clunk noise and engine seized up and wouldn't start. There were no warning signs. I had it towed to Honda dealership. Their official repair estimate states verbatim "Bearing on a connecting rod went bad and the rod snapped." The bill is $7800 for a remanufactured engine or $13500 for a new one. I had just had the vehicle's 40,000 mile inspection done at the same Honda Dealership 2 months prior, and no issues were found.

ELECTRICAL SYSTEM

I had the backup camera harness recall performed on my 2018 Honda Ridgeline on 09/06/2023 by Honda of Escondido , CA. (See attached invoice of recall work performed.) On 01/27/2026, the backup camera failed to appear on the dash screen when the vehicle was in reverse. I restarted the vehicle and the camera view was still not visible on the screen. I drove home and parked the vehicle in my garage. I turned the ignition off and then on again and put the car in reverse with the brake applied. This time the camera view was displayed on the dash screen. Appears to be an intermittent problem. (See attached two pictures of rear camera view not projected to the dash screen and one picture of my vehicle"s mileage, 50,518 miles.)

ENGINE

While driving the vehicle to the dealership to have them inspect the vehicle for a knocking noise coming from the engine at startup, the engine stalled. The engine locked up and had to be towed approximately 10 miles to the dealership. Upon inspection by the dealership after pulling the oil pan and inspecting for evidence of rod bearing failure, it was confirmed by the shop manager that there was indeed evidence of this in the oil pan.

ENGINE

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

ENGINE

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.

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

POWER TRAIN

We were traveling up the freeway just like any other day. Out of nowhere the low oil light flashed and next thing we know a loud clanking started to happen. We were able to make it to the exit as it was right there thankfully because once we stopped I shut the engine off got out and checked the oil and it was full. I tried to start it again, it started but turned it off fast because the noise it was making was horrible. I’ve contacted Honda regarding this issue because the Ridgeline from 2017 and 2019 are covered under a recall but the can’t explain why the 2018 is exempt from the recall seeing it’s the same engine.

POWER TRAIN

The transmission lost power on the highway. Whit smoke poured out from under/behind the vehicle making it difficult for drivers on the highway to see the road. The vehicle lost power and I costed three lanes to the right to get the vehicle off the highway. Transmission fluid was running out under the vehicle. A tow truck was called to get the vehicle removed from highway.

SUSPENSION

The vehicle’s front suspension system failed, specifically the driver’s side and passenger’s side front strut assemblies and the driver’s side inner and outer tie rods. These components have been identified by the dealership as needing immediate replacement. The defective components should be available for inspection upon request, pending completion of repairs. The vehicle exhibited wobbling and a dragging sensation from the front left tire, which raised concerns regarding control and steering safety. A loose or faulty suspension or tie rod can significantly impair vehicle handling, stability, and steering precision, particularly during acceleration, turning, or driving on inclines. If these components had failed while driving, it could have resulted in loss of control or an accident, posing a serious safety risk to both the driver and other road users. The issue was confirmed and diagnosed by a Honda dealership service department on March 18, 2025, and a detailed repair estimate was provided indicating strut and tie rod failure. The issue was inspected by a Honda-certified dealership service center, but not by the manufacturer, police, or insurance representatives at this time. There were no warning lights or messages on the dashboard. The only symptoms were a wobbling or loose feeling in the front left tire and a dragging sensation during acceleration on inclines, first noticed approximately two days prior to the March 18 service visit. Upon visual inspection, I also observed what appeared to be oil on the suspension, suggesting a possible strut fluid leak.
