Example complaints
One per model year, chosen for length and detail. Personal details are removed. They are consumer reports, not findings.
2006: “Upon detailed internal inspection of engine, it was determined that the balancer chain tensioning assembly had failed. Evidence showed that the spring (poorly made) had been broken for quite some time. It was also evident that had the spring not broken, the very poorly made tensioner quadrant would have broken instead leading to catastrophic engine damage and most likely a crash at the time of engine failure. The factory parts were replaced with upgraded aftermarket parts.”
