Pilot vs Nexo

For the allowed model years, the 2019 Honda Pilot is affected by the defective connecting-rod bearing problem. Symptoms include engine knock, loss of power, and possible catastrophic internal engine damage or complete failure. Honda issued a recall and stop-sale, so check the VIN and confirm the recall was completed before buying.

The nine-speed automatic in 2019-2022 Pilots is known for rough or jerky shifts, especially at low speeds; through 2020 it was used on Touring and Elite trims, and from 2021-2022 it was the only transmission. Consumer Reports and MotorTrend describe this as a driveability and refinement complaint rather than a confirmed mechanical failure. During a test drive, pay attention to low-speed gear changes, but do not automatically assume the harsh shifting means the transmission needs replacement.

Within the allowed model years, the 2019 Honda Pilot is the reported year for auto idle stop/start failure. The engine can shut off at a stoplight and then fail to crank back up when the driver releases the brake, potentially leaving the vehicle stranded in traffic unless manually restarted. No repair-cost estimate is provided by the research, but it is a safety and convenience defect worth investigating before purchase.

Early fourth-generation 2023-2025 Honda Pilots had several recalls, which is common after a full redesign. The research does not itemize the specific defects, but an unfixed open recall can leave safety-related or quality-related issues unresolved. Check the VIN on NHTSA's recall lookup and confirm all recalls have been completed before buying. Recall repairs are typically free, so the research does not provide a dollar repair estimate.

The hydrogen fuel system leak recall affects 2019–2020 Nexo models, where a defective check valve or filler neck connection can cause a slow hydrogen leak. Symptoms include a 'Check fuel system' warning and a hissing sound near the fuel filler port when parked, creating a fire or explosion risk and potential automatic shutdown. Out-of-warranty repair typically costs around $1,850 for replacing the filler neck and valve assembly.

The fuel cell system fault, most common on 2019–2021 Nexo models, is due to failure of the air compressor bearings or coolant pump. It triggers a 'Check Fuel Cell System' warning, sudden loss of acceleration, and limp mode, possibly with a loud whine from the compressor before failure. Replacement of the air compressor costs approximately $5,250, with additional costs if the coolant pump also needs replacement.

2019–2022 Nexo models suffer from premature 12V battery failure due to BMS logic that fails to keep the battery charged when parked, worsened by telematics drain. Symptoms include a dead battery, 'Battery discharge' warning, and inability to open the hydrogen fill port, leaving you stranded. A replacement AGM battery and BMS re-flash typically costs about $525.

The hydrogen fill door actuator fails on 2019–2023 Nexo models due to moisture or cycling wear, causing the door not to open or close properly. This triggers a 'Fuel door malfunction' warning and prevents refueling. Dealer replacement of the actuator and lock assembly costs around $265.
