All 11 Known Issues
Variable Cylinder Management (VCM) deactivates 3 cylinders during light-load driving to improve fuel economy. When inactive cylinders reactivate, vacuum pulls oil past piston rings into the combustion chamber, causing excessive oil consumption (1 quart per 1,000-1,500 miles vs. normal 1 quart per 3,000-5,000). Oil burning causes spark plug fouling, misfires, rough idle, and accelerated catalytic converter wear. 2013 class action lawsuit identified 1.6 million affected Honda vehicles including 2006-2013 Ridgelines.
Common Symptoms
- Excessive oil consumption (1 quart per 1,000-1,500 miles)
- Engine misfire codes P0300-P0306
- Fouled spark plugs with carbon buildup and wet deposits
- Rough idle or hesitation
- Check engine light illuminated
- Blue or gray smoke from exhaust
- Excessive engine vibration when VCM activates
How to Fix
Disable VCM using aftermarket devices: VCMuzzler II ($81), VCMTuner II ($150-$200), or S-VCM Controller ($180-$250). Check oil level every 500-1,000 miles until VCM disabled. Use synthetic 0W-20 oil. Replace spark plugs every 30,000-50,000 miles instead of 100,000. Severe engine damage may require rebuild ($4,000-$8,000).
What Owners Are Using
Parts and tips from 200+ owners who fixed this issue
- UpgradeVCMuzzler II ($81) is most recommended for budget-conscious owners - simplest install, no power wire needed, 1-minute installation
- UpgradeVCMTuner II ($150-$200) preferred for newer models with automatic temperature sensing and overcooling protection
- TipMonitor oil level obsessively and keep 2-3 quarts in vehicle for top-offs between oil changes
- NoteInstall VCM disabler as preventive measure, not reactive - engine damage from oil consumption is permanent and expensive
- TipReplace spark plugs every 30k-50k miles instead of 100k - fouled plugs cause misfires that damage catalytic converters ($1,500-$3,500)
- TipDisabling VCM also protects engine mounts and transmission from excessive wear and vibration
The 3.5L aluminum engine with steel spark plugs experiences thermal stress due to temperature differences. Spark plugs back out (loosen) due to aluminum block expansion/contraction cycles, causing misfires and potentially breaking inside the combustion chamber. Loose spark plugs allow coil packs to melt and enter the engine block causing catastrophic damage. After 60,000 miles, Honda service bulletins specify spark plug torque should be double-checked. Affects all J35 engine platforms (Pilot, Odyssey, Ridgeline).
Common Symptoms
- Misfire codes P0300-P0306
- Check engine light
- Rough idle or hesitation
- Coil pack melting or burning visible in cylinder
- Complete engine failure if melted coil enters combustion chamber
- Engine won't start (broken/loose plugs)
How to Fix
At 60,000 miles: remove spark plugs and re-torque to proper spec (18 ft-lbs) using torque wrench. Inspect each plug for backing out or looseness. Use OEM Honda spark plugs only. Coil pack replacement if melted: $150-$300 per coil + labor. Engine head repair if melted coil damaged head: $1,500-$3,000+. Full engine rebuild if catastrophic: $4,000-$8,000+.
What Owners Are Using
Parts and tips from 65+ owners who fixed this issue
- TipUse torque wrench when installing spark plugs - do not over-tighten (18 ft-lbs spec exactly)
- TipAlways work on engine when completely cool - aluminum expands significantly when hot and causes incorrect torque readings
- TipCheck spark plug torque at 60,000 miles and every 30,000 miles thereafter as preventive maintenance
- UpgradeUse OEM Honda plugs at $3-$5 each - aftermarket plugs from different manufacturers may have inconsistent heat ranges
- NoteHave coil packs inspected immediately if misfire codes appear - replacing coils early prevents catastrophic $4,000+ engine damage
NHTSA investigation EA25-004 covers 2.2 million Honda vehicles including 2020-2023 Ridgeline for idle stop and go (ISG) system failure to restart engine after automatic shutdown at stop lights. Vehicle may fail to automatically restart when stop ends, requiring driver to manually restart by shifting to Park and pressing ENGINE START/STOP button. Honda released TSBs 23-008, 23-009, 23-010 with two-stage remedy: Stage 1 involves PCM software update; Stage 2 (if software fails) involves starter assembly or relay replacement with 10-year unlimited mileage warranty extension. Despite repairs, NHTSA continues receiving complaints of failures even on vehicles with TSB applied.
Common Symptoms
- Engine fails to automatically restart when traffic resumes
- Requires manual restart by pressing ENGINE START/STOP button
- Intermittent failures (sometimes restarts, sometimes doesn't)
- Check engine light appearing with starting system codes
How to Fix
Stage 1: Visit Honda dealer for PCM software update (free under warranty) - TSB 23-008, 23-009, 23-010 references. Labor: 1-2 hours. Stage 2 (if software doesn't resolve): Replacement of starter motor or related relays. Starter replacement: $300-$500 + labor. Relay replacement: $50-$150 + labor. Free if within extended warranty (10 years unlimited miles per TSB). Out-of-warranty cost: $350-$800.

The radiator internal cooler corrodes at seams and fittings, allowing coolant to mix with transmission fluid in a condition known as "SMOD" (Strawberry Milkshake Of Death). This coolant contamination destroys all clutch packs and friction materials in the 5-speed transmission. 2006-2008 models see highest failure rates, particularly in rust-belt states past 80,000-120,000 miles. Unlike manufacturer recalls, Honda did not formally recall despite numerous failures.
Common Symptoms
- No drive or reverse suddenly
- Transmission refuses to engage gears
- Pink or milky transmission fluid (coolant mixed with ATF)
- Rough shifting before complete failure
- Transmission overheating
- Loss of power during acceleration
How to Fix
Proactive radiator replacement at 100,000 miles as preventive maintenance ($300-$600). If SMOD has occurred: full transmission rebuild or replacement ($4,000-$6,000). Use Honda ATF 3.1 or equivalent. Many owners replace radiator every 100k miles as insurance policy.
What Owners Are Using
Parts and tips from 150+ owners who fixed this issue
- UpgradeReplace radiator at 100k miles with OEM or Denso radiator as preventive measure - $300-600 prevents $4,000+ transmission replacement
- TipCheck transmission fluid color every oil change - pink or milky indicates coolant intrusion and immediate service needed

The 10-speed automatic transmission (replaced 6-speed from 2017-2019) exhibits rough and delayed shifting, loud noises during gear changes, sudden harsh accelerations/decelerations, jerking at all speeds, and sudden loss of power. Class action lawsuit alleges programming defect where the transmission control module doesn't communicate properly with powertrain control module, causing gear shifting to be mistimed. Common complaint: transmission slip followed by hard shift from 2nd to 3rd gear occurring nearly every time under harder acceleration, hill climbing, or with weight in bed.
Common Symptoms
- Rough or delayed shifting between gears
- Transmission jerking or hesitation
- Loud clunking or banging during shifts
- Sudden loss of power or acceleration
- Transmission slip followed by hard shift
- Check engine light with transmission codes
- Issues worse when under load (towing, bed weight, hills)
How to Fix
Perform transmission software update at Honda dealer (may help but may not fully resolve). Transmission fluid change using Honda ATF (specific type for 10-speed) every 30,000 miles: fluid cost $40-$80 + labor $150-$250 = total $200-$330. Check for transmission recall status with VIN. Full transmission replacement if programming update and fluid service don't resolve: $4,000-$6,000. Class action lawsuit may provide compensation.
