Back on topic, here was our latest leak. And our mufflers were leaking exhaust, where the pipe goes into the muffler. On a cold morning start you could see the puffs of smoke coming from the failing welds, but of course they say nothing was wrong.
They even charged us $160 to look at the cracked exhaust, so they could tell us it wasn't covered. Thermal exhaust fixed that, because they refused to fix any exhaust problems with the extended warranty.
Output shaft seal.
