NHTSA Complaint #11613659 — 2016 VOLVO XC90

Started getting high coolant temperature warning, indicating to slow down and then after a short while to stop the vehicle. The vehicle now cannot be driven without the warning showing up after several minutes of driving after sitting. Of course comes on much sooner if it's been running before that. We had to pull over and wait several times during interstate travel. No codes are present using a code reader. It reads the temp at around 215 degrees when warning comes on to slow down. Continues to increase until warning to stop vehicle. I inspected the engine. A lot of symptoms were inline with a bad thermostat. Changed that with no luck. I again inspected the engine and found the broken tube. It was inline with where it's supposed to be attached, so it was missed the first time. I researched online and found recall 19V308 related to a previous version of the part. The newer version is installed (Volvo part 31238231), yet the same exact conditions are present that the replacement was supposed to avoid. Seems reasonable that if that's the case, it should also be covered by another safety recall. The pics also include coolant accumulation in that area as well as corroded plastic conduit for what looks like some type of wire for electrical component. I'm not sure what that part is, but I've sent a pic also of where it goes into the engine. Seems like the higher heat that the coolant can reach eventually melted/corroded the conduit. The wire inside is also not in good shape, but is intact still.
