Car drove normally, except for a loud whine and a shudder when starting from a complete stop. OBD2 scanner showed excessive MG2 temperatures, so the shop replaced the motor assembly. (Repair cost is approximate) |

| 165850 mi | Water accumulated in spark plug well causing misfiring. Removal of coil, absorption of water with paper towels, replace parts and test. The water found it's way into the spark plug well because I'd been parking the car under a tree and falling leaves were blocking drains at the base of the windshield. When it rained intensely, water overflowed onto the engine. The rocker cover has a recessed area where the coil and spark plugs ate fitted - a good spot for water to collect! |
