2021 Honda Ridgeline Reliability Score & Common Problems

Owners report that the 2021 Honda Ridgeline frequently experiences power train issues, particularly involving the vehicle unexpectedly shifting to neutral or going into limp mode. Complaints frequently mention the vehicle shifting to neutral while driving or when stopped, often accompanied by a transmission failure alert. Another common issue occurs after extended highway driving, especially in cold weather, where the vehicle enters limp mode, limiting speed to 30-35 mph and causing the engine light to flash. These issues typically emerge at low mileage, often under 10,000 miles. Safety implications are significant, with owners describing situations where the vehicle's loss of power occurs in traffic, potentially leading to dangerous conditions. Additionally, multiple reports note the inability to manually shift the vehicle into neutral without a specific tool, which is not readily available, posing a risk if the vehicle stalls in traffic.

Owners report that the 2021 Honda Ridgeline's forward collision avoidance system frequently issues false warnings and engages automatic braking unexpectedly. Typical symptoms include the vehicle braking for cars in adjacent lanes, issuing alarms and flashing "Brake" alerts, and activating on two-way roads and curves. Multiple complaints describe this occurring despite no obstacles being present, with some owners noting it happens on roads with slight curves or when another vehicle is in a turning lane. These occurrences can lead to sudden braking, posing a risk of rear-end collisions. Some owners have attempted to adjust sensitivity settings or disable features to mitigate these issues, but reports suggest persistent problems since early 2021.

Owners report several structural issues with the 2021 Honda Ridgeline. Complaints frequently mention distorted side view mirrors following a recall, causing discomfort and nausea. Additionally, there are reports of the tailgate unexpectedly opening while driving, without triggering a warning light. Another issue involves front fender flares detaching at highway speeds due to inadequate fastening, leading to potential loss of control. One injury is noted from a sharp edge on the truck bed lid, which cut an owner's finger. These issues appear across vehicles with various mileages, including as low as 2,000 miles, and may pose safety risks.

Owners of the 2021 Honda Ridgeline report issues primarily related to engine failure and the Auto START/STOP feature malfunctioning. Common symptoms include the vehicle entering LIMP mode, abnormal knocking and popping sounds from the engine compartment, and low oil level warnings. Complaints frequently mention that these problems occur at mileages ranging from approximately 50,500 to 102,000 miles. Engine failures often require significant repairs, such as engine replacement, due to issues like disconnected connecting rods and low oil levels. These issues can lead to vehicle stalling or inability to restart, which may pose safety risks, particularly if they occur while driving.

Owners of the 2021 Honda Ridgeline report issues related to airbag recalls, primarily concerning delays in obtaining necessary parts for repair. Complaints frequently mention difficulties in scheduling and completing recall repairs due to parts unavailability, with some owners noting this issue has persisted since at least September of the previous year. The symptoms described by owners mainly involve frustration with appointment cancellations and lack of resolution, rather than specific airbag malfunctions or failures. No incidents of crashes, fires, or loss of control are reported in connection with these airbag issues. Prospective buyers should be aware of potential delays in recall-related repairs and check the availability of parts if considering purchasing this model.

Owners of the 2021 Honda Ridgeline report issues with vehicle speed control, particularly involving unexpected deceleration. One complaint describes a failure to accelerate above 30 MPH after slowing down, requiring the driver to pull over and restart the vehicle, with the issue self-correcting thereafter. This incident occurred at approximately 22,000 miles. Another complaint highlights a problem with the adaptive cruise control system, where the vehicle continues to slow down even after the car in front changes lanes, posing a potential risk of rear-end collisions. These issues suggest potential safety implications, particularly in traffic situations, and may be relevant to prospective buyers considering this model.

Owners of the 2021 Honda Ridgeline report issues related to the service brakes, with one incident involving a crash and injury. Complaints frequently mention a lack of braking effectiveness, as one owner describes an inability to slow down in time to avoid a collision, with no skid marks left on the road. Another owner reports the "BRAKE" warning flashing on the dashboard without any apparent cause or actual braking action. These issues occur in varied driving conditions and do not specify a particular mileage range. The reported crash and injury highlight potential safety implications for prospective buyers.
