VCM (Variable Cylinder Management) on V6 cars can raise oil consumption and cause vibration.
- Typically appears
- 60,000+ miles
- What to inspect
- Check oil level and look for aftermarket VCM disablers; feel for vibration at cruise.

The ninth-generation Accord is a strong, efficient used buy, but the V6's cylinder-deactivation system and a few electronics quirks deserve a look.
Compiled & reviewed by the VehicleFaults Research Team · last reviewed July 2026
The most commonly reported faults on the 2013–2017 Honda Accord are Intermittent no-start condition or a loud clicking noise when attempting to crank the engine, VCM (Variable Cylinder Management) on V6 cars can raise oil consumption and cause vibration and V6 automatic torque-converter judder. 1 of the documented issues are rated high severity · inspect these first.

Steering pulls to one side on a flat road or feels notched and heavy off-centre due to Electronic Power Steering (EPS) rack issues.
Humming, droning, or rumbling noise from the rear of the vehicle that increases with road speed due to premature wheel bearing wear.

Build my inspection planVery — it's a top-rated used sedan. Watch the V6's VCM oil use and infotainment glitches.
The 2.4L four is trouble-free and efficient; the V6 is smoother but adds the VCM oil-consumption risk.
The 2013–2017 four-cylinder uses a CVT that is generally durable; keep up with fluid changes.
It depends on the engine fitted. The 2.4-litre four-cylinder engines utilise a durable timing chain that generally lasts the lifetime of the vehicle with regular oil changes. Conversely, the 3.5-litre V6 engines are fitted with a timing belt, which mandates replacement every 60,000 to 100,000 miles or seven years, alongside the water pump.
Yes, the 2.4-litre Earth Dreams engine uses direct injection, which bypasses the intake valves with fuel, preventing the natural cleaning effect. Over time, carbon deposits can accumulate, leading to rough idling, misfires, and reduced fuel economy. Dealers should check for a smooth idle and recommend an intake decoke service if rough running is detected.
A brief, harsh rattle lasting a few seconds on a cold start is typically caused by a faulty Variable Timing Control (VTC) actuator. The internal locking pin fails to engage properly when oil pressure drops overnight. While it rarely causes immediate catastrophic engine failure, the actuator must be replaced to prevent long-term timing chain wear.
