I am having serious doubts about the quality of this product, and I am curious about if others have had similar experiences. I am now out of warranty (four years old), but the engine only has 140 hrs. on it. The exhaust elbow rotted out (galvanic corrosion) and caused the hose that is attached to it to leak. I replaced these items with parts ordered from Fischer-Panda, but immediately discovered that the genset no longer produced any AC current. The factory-authorized mechanic has made a preliminary analysis that all four capacitors have failed. There may be more issues as he delves into this. I also had a fuel pump failure at 20 hrs., as well as a relay switch and fuse failure later on. It seems ridiculous to have this many problems at so few hours, as well as the type of failures. Did I end up with a lemon or are my problems common with this product? The exhaust-elbow-hose design seems like a design failure issue, not simply a defective part problem. Also, why on earth should a new genset be deemed out of warranty after only 140 hrs. of use?
