Fuel Pump Failure (Recall)
The low-pressure fuel pump inside the fuel tank may fail, causing the engine to stall without warning while driving. Symptoms include rough idle, hesitation during acceleration, and sudden engine shutoff. This recall covers a wide range of 2017-2023 Ridgeline models.
Honda issued recall 23V-858 to replace the fuel pump module free of charge. This expands earlier recalls 21V-215 and 20V-314. Contact your dealer to check VIN eligibility.
Est. Cost: Covered under recallRearview Camera Image Loss (Recall)
The rearview camera mounted in the tailgate has a wiring harness that can become brittle and break when exposed to cold temperatures and road salt. This causes the backup camera to display a black screen or no image at all when the vehicle is in reverse.
Honda issued a recall for 2020-2024 Ridgeline models to replace the rearview camera wiring harness with an improved design. The repair is performed free of charge at authorized dealers.
Est. Cost: Covered under recallAWD Warning Light from Rear Differential Water Intrusion
Water can intrude into the rear differential pump motor connector area, corroding the terminals and triggering the AWD warning light on the dashboard. The SH-AWD system may default to front-wheel-drive mode, reducing traction capability.
Honda issued a TSB to address water intrusion at the rear differential connector. The dealer will clean or replace the corroded terminals, reseal the connector, and clear the warning codes. A protective cover or sealant may be applied to prevent recurrence.
Est. Cost: $200 - $600 (may be covered under warranty)EVAP System Purge Valve Sticking (Check Engine Light)
The purge control solenoid valve spring can cause the valve to wear unevenly and intermittently stick, setting diagnostic trouble code P0441 (Evaporative Emission System Purge Flow Malfunction). The check engine light illuminates, and the vehicle may fail emissions testing.
Honda issued a TSB to replace the purge control solenoid valve with an updated part. The repair is straightforward and typically takes less than an hour.
Est. Cost: $100 - $300Cold-Weather Air Intake Icing
In cold weather, moisture can collect in the air intake system and freeze, potentially restricting airflow to the engine. This can cause rough idle, loss of power, stalling, or difficulty starting after the vehicle has been sitting in sub-freezing temperatures.
Honda issued TSB 24-085 addressing moisture accumulation in the air intake during freezing conditions. The dealer may install an updated air intake duct or baffle to prevent ice formation. Parking in a garage when possible reduces the risk.
