Honda Ridgeline loss of power problems

Filed Oct 30, 2026 · Electrical, Transmission · CA

My 2023 Honda Ridgeline (about 28,400 miles) repeatedly loses power while driving. The instrument cluster lights up with every warning light at once, the truck stops accelerating, and I cannot maintain speed. It has happened on the freeway above about 60 mph, which is extremely dangerous with surrounding traffic moving at highway speed. Disconnecting the battery for about 15 minutes temporarily clears the warning lights and lets the truck move again, but the problem keeps returning. I have taken the vehicle to a Honda dealer three times for this same problem: July 2026, late August 2026, and October 2026. At the August visit, the dealer scanned the vehicle and found multiple lost-communication codes and DTC U0401 (invalid data received from PCM). The powertrain control module (PCM) was replaced under warranty and relearn procedures were performed. The problem returned after the replacement, and the truck is again at the dealer for diagnosis. I have video recordings of the failures and repair records for all three visits. I am concerned this is a defect in the powertrain control or vehicle communication system that can cause a sudden loss of power at highway speed, and that other owners may be affected. Please investigate.

With no warning engine started making a loud ticking noise and within a couple of days it was a loud knocking noise. Flashing check engine light came on and engine lost power. Shut down and restarted engine, knocking noise still there but check engine light is not flashing. Knocking noise is loud and vehicle cannot be driven. Mileage is around 170000 but has had regular oil changes. Mechanic has confirmed the engine knock and said not to drive it. Can't afford to replace the engine.

I own a 2017 Honda Ridgeline with the 3.5L V6. The vehicle developed a noticeable engine knocking noise along with a check-engine light. I took it to a Honda dealership for diagnosis. The dealer confirmed abnormally low oil pressure, reporting approximately 6–7 PSI at idle on Bank 2, and recommended complete engine replacement at an estimated cost of approximately $9,000. To my knowledge, the dealer has not identified the exact internal component causing the knocking noise or low oil pressure. The vehicle and engine are available for inspection. This vehicle has a significant prior engine-failure history. At approximately 102,851 miles, the previous engine suffered a spun No. 2 connecting-rod bearing, crankshaft/connecting-rod damage, and metal contamination in the oil system. That engine was replaced with a used engine, which is the engine currently installed. Before the current diagnosis, diagnostic code P2651 was present. The related oil-pressure switch and rocker-arm oil-control solenoid were replaced and the codes cleared, but the abnormal engine knocking remained. I am concerned this condition could result in engine seizure, stalling, or sudden loss of power while driving. Because of the knocking noise and confirmed low oil pressure, I do not consider the vehicle safe to drive. I am aware the federal safety agency is investigating connecting-rod-bearing failures involving 2017–2019 Honda Ridgelines and other Honda/Acura vehicles. Given this vehicle's prior documented connecting-rod-bearing failure and its current knocking/low-oil-pressure condition, I am submitting this complaint so the federal safety agency can determine whether it may be related to the broader issue under investigation. The vehicle has been inspected by a Honda dealership, and I have contacted American Honda for assistance.

I am writing to formally report a serious safety concern involving my vehicle, which experienced a sudden engine shutdown while I was driving on the busy [XXX] toward the [XXX]. The engine unexpectedly stopped operating due to oil-related and engine issues, creating an extremely dangerous situation for me and potentially for other motorists traveling on the roadway. Having a vehicle suddenly lose engine power while traveling at highway speeds presents a significant safety hazard. The unexpected loss of power can leave a driver with limited ability to maneuver safely, increase the risk of a collision, and expose the driver and passengers to danger from surrounding traffic. In my situation, the engine failure occurred without warning while I was on a busy highway, placing my safety and the safety of others at risk. I am concerned that the circumstances surrounding this failure may indicate a potential safety-related defect involving the vehicle's engine or oil system. I respectfully request that the federal safety agency review this incident and determine whether similar complaints have been reported involving this vehicle, its engine, or related oil-system components. If a broader pattern of failures exists, I ask that the agency consider whether further investigation or appropriate corrective action is warranted. I would appreciate guidance regarding the proper process for submitting supporting documentation, including repair records, diagnostic reports, photographs, maintenance history, and any other information that may assist your investigation. I believe that sudden engine failure under these circumstances deserves serious attention because of the potential consequences for public safety. My intention in submitting this complaint is to ensure that this incident is documented and evaluated, and to help determine whether other vehicle owners may be facing a similar risk.

I own a 2017 Honda Ridgeline with approximately 128,000 miles. In late August 2026, I noticed a deep knocking noise coming from the engine shortly after an oil change. The knocking increased with engine RPM and continued even after the engine warmed up. The oil level appeared full, and there was no oil-pressure warning light. I brought the vehicle to Liberty Honda in Connecticut for diagnosis. Their technician investigated the noise, identified it as internal connecting-rod knock, and determined that the engine requires complete replacement. The dealership quoted approximately $19,210 plus tax for the repair. I have driven approximately 40,000 miles since purchasing this vehicle and have consistently maintained it. Oil changes were performed at Valvoline approximately every 3,000–5,000 miles using their premium oil service. Routine maintenance was performed by an independent mechanic, while major repairs were handled by Honda dealerships. The timing belt was serviced at approximately 84,000 miles. I am concerned because Honda previously recalled certain 2017 Ridgelines for connecting-rod-bearing defects, and the federal safety agency has separately investigated similar failures in 2017–2019 Ridgelines outside the original recall population. My vehicle has experienced the same type of failure being investigated This condition presents a serious safety concern because connecting-rod-bearing failure can cause sudden engine failure and loss of power while driving. I have avoided further driving because of this risk. American Honda denied my request for goodwill assistance toward engine replacement. I am reporting this failure so the federal safety agency can evaluate it alongside similar complaints.

just got on the freeway when car lost power, slowed down, check engine light turns on, and more lights start flashing. Potentially could have caused an accident if I was going faster on road. Went to mechanic, Code P0301, after diagnosis, fuel injectors failing. Mechanic was able to reproduce incident. Similar to recall for previous models, but not recalled on 2022 model. Need to replace fuel injectors. Had minor loss of power a few days prior, but not as severe

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.

I am submitting a safety complaint regarding my 2023 Honda Ridgeline with approximately 23,995 miles. My primary concern is an intermittent transmission/powertrain malfunction. While driving on the highway, the vehicle unexpectedly entered limp/fail-safe mode and experienced a significant loss of power and acceleration. This created a potentially dangerous situation because I was unable to accelerate normally while traveling with highway traffic. I am concerned that this could happen again without warning while merging, changing lanes, crossing an intersection, or attempting to avoid another vehicle. The electronic transmission selector has also intermittently stuck or failed to operate smoothly. I am requesting that the federal safety agency investigate whether other 2023 Honda Ridgeline owners have reported similar transmission warnings, limp-mode events, loss of propulsion, reduced acceleration, transmission-selector malfunctions, or related powertrain problems. The vehicle also has premature deterioration of both headlamp lenses, including fading, hazing, and cloudiness. I am concerned this may reduce nighttime light output and roadway visibility. Additionally, the engine produces an abnormal rattling noise during cold starts. Rust/corrosion is developing beneath the door weather seals, and the exterior window/pillar trim is prematurely fading and deteriorating. My most serious concern is the unexpected transmission malfunction and loss of power at highway speed. At only approximately 23,995 miles, I believe this condition warrants investigation because an unexpected reduction in propulsion can increase the risk of a collision.
