Any updates Carbuff? Or Kinshi?
So when I got my car back two weeks ago, the 12v battery was dead when I tried to leave work later the same day that I got it back. This pissed me off as I had asked the dealer to check it like 2 months earlier, and asked again when I picked up the car. They'd said the 12v battery tested good. I stomped off to the nearest hardware store, luckily only 1/2 mile away and bought an overpriced jump starter that luckily was fully charged. I put in a new battery rather than waste more time bothering the dealer .
Monday this week it was raining, I drove through some puddles, and just as I got home the yellow wrench showed up. Here we go again I thought. I shut off the car in the garage and slept fitfully with visions of that dreadful red SSN box. Luckily in the morning the wrench was gone, no more rain and all is well since then.
After reading triangles' suggestion about the HV connection in the left rear wheel well, I'm thinking I could fabricate a watertight box and glue it in place over that connector with liberal amounts of caulk window sealant. Preferably before the next time it rains. Would that work?
