Engine trouble light came on Nov. 2009. Talked to dealership they said the light had to be on at time of comp. Diagnostic. Came on again in Dec. 2009. Had diagnostic done at dealer & independently, the code indicated a cylinder misfire. The dealership ordered parts, which took two months to get (Feb. 2010). In the mean time the car was running with a cylinder misfire the whole time causing it to run hot, which created a large burn hole in the front exhaust pipe/converter assembly (which Suzuki attributed to a poor engine ground). The dealership "fixed" the cylinder misfire by replacing some 34 internal parts associated with the cam shaft or crank "tensioner and guide". two months later (April 2010)the alternator mounting bolt and pulley assembly (recall NHTSA # 10V25000)both broke. That is where the dealership notice the hole in the front exhaust and attributed it to a "poor engine ground" when an independent Firestone mechanic already told me that hole was a direct result of the engine running hot for so long due to the "cylinder misfire". now here it is a year later and the same problem is present. I believe there is a manufacturing quality defect issue.
