6.7/10
1 walk-away risk, 4 serious faults, 3 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: j35 connecting-rod bearing recall. Score methodology.
The 2018-2025 Odyssey is a very useful minivan, but it is not the simple old Honda people remember. The costly traps are 2018-2023 MOST coax camera/infotainment failures, 2018-2020 instrument/network software recalls, 2018-2019 connecting-rod bearing recall exposure, 2019 timing belt recall, 2018-2020 seat-belt buckle recall, 2020-2022 mirror glass recall, and 10-speed or early 9-speed transmission complaints. The safest buy is a 2022-2025 10-speed van with closed camera, pump, mirror and seat-sensor recalls plus clean timing-belt service records. Owners should keep infotainment, recall, transmission-fluid and timing-belt records together because family buyers punish uncertainty.

Best years
2022-2025
Best buys
- 2022-2025 EX-L/Touring/Elite with completed MOST camera recall and regular ATF service.
- 2020-2021 10-speed van after network software, mirror and pump recalls are closed.
- 2018-2019 only with rod-bearing recall result, 9-speed behaviour checked, and full belt service.
Inspect hard
- 2018-2023 vans: reverse camera, CabinWatch, RES audio, popping/crackling, black screens, and MOST cable repair proof.
- 2018-2019 J35: rod-bearing recall 23V751 and timing-belt recall 19V298 where applicable.
- Any high-mileage van: sliding doors, water leaks, mounts, ATF colour, and family-interior abuse.
Avoid
- Van with blank reverse camera or infotainment network faults still unrepaired.
- 2018-2019 with engine knock, bearing recall uncertainty, or timing-belt recall open.
- Transmission shudder/whine with no fluid history.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which Honda Odyssey should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
3.5L J35Y6 V6 with ZF 9-speed
2018-2019 lower trims
INSPECT HARD
Early lower-trim vans used the ZF 9-speed. It can be fine, but shift quality complaints and software/fluid history matter. Combine that with 2018-2019 engine recall checks before trusting a cheap launch van.
3.5L J35Y6 V6 with Honda 10-speed
2018-2025 selected/high trims; all trims later
BEST POWERTRAIN
The 10-speed is the better Odyssey transmission, especially in later years. It still needs ATF service and road-test attention because a minivan works hard in heat, hills, and school-run stop-start use.
J35 V6 timing-belt service package
2018-2025 maintenance item
BUDGET IT
This engine uses a belt, not a chain. A used Odyssey near 100k miles without timing belt, water pump, tensioner and coolant records is not fully serviced, even if the oil changes are perfect.
VCM cylinder-deactivation system
2018-2025
WATCH MOUNTS/OIL
VCM improves fuel economy but can add mount vibration and oil/plug sensitivity on neglected J-series vans. Check engine mounts, plug history, and smooth cylinder transitions under light throttle.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2018
Fifth-gen launch. 9-speed on lower trims, 10-speed on Touring/Elite, early infotainment and seat-belt recall exposure.
Buyer: A 2018 is cheap for a reason. Check transmission behaviour, MOST issues, seat-belt recall and engine recall status.
Owner: Keep every infotainment visit documented; launch vans need proof more than promises.
2019
Timing belt recall affects some 2019 vans; fuel pump and bearing recall exposure also appear in this period.
Buyer: Do not buy a 2019 until timing-belt and rod-bearing campaign status are clear.
Owner: If the belt recall applied, keep the dealer belt record with the normal timing-belt service file.
2020
Instrument and central network software recalls affect Odyssey; mirror recall population starts.
Buyer: Test camera and cluster behaviour repeatedly. A clean software history matters more than trim level.
Owner: If camera delay returns after software, ask the dealer to check the MOST recall path.
2021
Facelift year; 10-speed is standard in North America, and fuel-pump recall exposure remains.
Buyer: This is a better year if recalls are closed and ATF service is documented.
Owner: Do not let ATF service slide because the 10-speed is expensive when neglected.
2022
Mirror recall and MOST recall coverage overlap; passenger sensor recall affects selected vans.
Buyer: A 2022 is a strong target after mirror, camera and OCS checks.
Owner: Close mirror and camera recalls before selling; both are obvious during a viewing.
2023
MOST rear-camera recall still covers Odyssey, while drivetrain risk is lower than launch years.
Buyer: Prioritise electronics and service history over mileage alone.
Owner: Keep screen/camera proof; buyers are now trained to test these vans.
2024
Mature production with fewer recall headlines, still same J35/timing-belt maintenance reality.
Buyer: A 2024 should feel nearly new. Any camera, door, or shift issue deserves a discount.
Owner: Document maintenance from new so the van does not get priced like an abused family hauler.
2025
Final stretch of fifth-gen with feature updates depending market.
Buyer: Nearly-new pricing only makes sense with flawless electronics and warranty transfer.
Owner: Preserve warranty value; avoid aftermarket wiring in a network-sensitive van.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
MOST coax rear-camera and infotainment recall
Affects
2018-2023 Odyssey under 23V431.
Symptoms
Blank reverse camera, popping audio, black screen, CabinWatch/RES errors, intermittent Bluetooth/USB.
Typical repair cost
EUR 0 recall; EUR 300-1,800 customer-pay network repair.
Codes / scan clues
MOST/network communication codes possible.
Root cause: Faulty MOST coax connector can interrupt camera and infotainment data.
Quick check
- Reverse camera several times.
- Test CabinWatch/RES/audio.
- Drive over bumps while listening.
- Verify 23V431 invoice.
Buyer note
A van with intermittent camera or audio faults is not fixed until the exact MOST repair is documented.
Owner note
Record failures on video; intermittent network faults are easier to dismiss without proof.
Fault 2
Instrument/control network software camera recalls
Affects
2018-2020 Odyssey under 20V439 and 2019-2020 Odyssey under 20V440.
Symptoms
Cluster blank/delayed, camera missing, warnings delayed, screen reboot.
Typical repair cost
EUR 0 recall; EUR 150-900 software/module diagnosis.
Codes / scan clues
Network/IPCM codes.
Root cause: Incorrect software in instrument/control network can prevent required displays.
Quick check
- Run VIN.
- Cycle ignition.
- Check cluster, gear display and camera.
- Review software campaign records.
Buyer note
A 2018-2020 van with display weirdness needs campaign status confirmed before purchase.
Owner note
Mention both software recall numbers when booking; the symptoms overlap with MOST faults.
Fault 3
J35 connecting-rod bearing recall
Affects
Certain 2018-2019 Odyssey under 23V751.
Symptoms
Engine knock, low oil pressure, metal debris, seizure risk, recall notice.
Typical repair cost
EUR 0 recall; EUR 5,000-12,000 engine repair outside coverage.
Codes / scan clues
Oil pressure/misfire possible.
Root cause: Manufacturing error may cause rod bearing wear and engine seizure.
Quick check
- Run VIN for 23V751.
- Listen cold and hot for knock.
- Check oil/filter records.
- Avoid any bearing noise.
Buyer note
A bearing-recall Odyssey without a clear Honda result is too risky for family transport.
Owner note
Do not ignore knocking; engine seizure is the failure mode.
Fault 4
Timing belt tooth separation recall and normal belt service
Affects
Certain 2019 Odyssey under 19V298; all 2018-2025 need belt service by age/mileage.
Symptoms
Recall notice, rough running, no-start, engine damage if belt fails.
Typical repair cost
EUR 0 recall; EUR 900-1,800 timing belt/water pump service.
Codes / scan clues
Cam/crank correlation or misfire if timing slips.
Root cause: Recall belts may have tooth separation; normal J35 belt ages with use.
Quick check
- Run VIN for 19V298.
- Check belt service sticker/invoice.
- Listen for tensioner noise.
- Budget water pump/tensioner together.
Buyer note
A high-mile Odyssey without timing-belt proof is under-serviced.
Owner note
Do belt, water pump, tensioner and coolant as a package.
Fault 5
9-speed or 10-speed transmission shift/whine complaints
Affects
2018-2019 9-speed lower trims; 2018-2025 10-speed if fluid neglected.
Symptoms
Harsh shifts, delayed engagement, whine, shudder, clunk under load.
Typical repair cost
EUR 200-450 ATF/software; EUR 4,000-8,000 transmission replacement.
Codes / scan clues
Transmission pressure/ratio codes possible.
Root cause: Software, fluid degradation, torque converter or internal wear depending unit.
Quick check
- Cold D/R.
- Light and medium throttle shifts.
- Confirm ATF service.
- Check mounts and axle noises.
Buyer note
The 10-speed is preferable, but neither gearbox should be bought blind.
Owner note
Regular ATF service is cheap compared with van transmission replacement.
Fault 6
Front seat-belt buckle recall
Affects
2018-2020 Odyssey under 23V158.
Symptoms
Buckle difficult to latch, release-button interference, SRS/belt warning.
Typical repair cost
EUR 0 recall; EUR 250-700 buckle.
Codes / scan clues
SRS/belt codes possible.
Root cause: Buckle channel manufacturing issue can block proper latching.
Quick check
- Run VIN.
- Latch/unlatch both front belts.
- Check SRS lamp.
- Confirm repair invoice.
Buyer note
Family vans need belt recalls closed before handover.
Owner note
Complete the recall even if the buckle only sticks occasionally.
Fault 7
Side mirror glass detachment recall
Affects
2020-2022 Odyssey under 23V174.
Symptoms
Mirror glass loose, vibration, heated mirror backing separation.
Typical repair cost
EUR 0 recall; EUR 150-500 mirror glass.
Codes / scan clues
None.
Root cause: Heater pad bond may fail, allowing mirror glass to detach.
Quick check
- Run VIN.
- Touch mirror glass gently for looseness.
- Test heat.
- Confirm recall completion.
Buyer note
Easy to fix, but open mirror recalls show poor maintenance admin.
Owner note
Replace before it falls off; the part is safety related.
Fault 8
Sliding door, water intrusion and family-use wear
Affects
2018-2025 Odyssey, especially high-use family vans.
Symptoms
Door reverses, beeps, wet carpet, erratic interior lights, ADAS warnings after leaks.
Typical repair cost
EUR 150-800 door/roller/switch; EUR 500-2,500 leak/electrical repair.
Codes / scan clues
Door control, body, ADAS communication codes.
Root cause: Door roller/sensor wear, drains/seals, and interior moisture affecting body electronics.
Quick check
- Operate both doors many times.
- Lift mats/cargo floor.
- Check rear quarter trim for dampness.
- Scan body modules.
Buyer note
A clean-looking van can hide wet carpets and door faults under child seats.
Owner note
Fix leaks early; moisture turns small trim issues into module faults.
