NHTSA Complaint #11488496 — 2012 VOLVO XC60

A faulty radiator anti-tamper device caused loss of communication to the engine control computer. The check engine light turns on and “charging failure-service urgent” message pops up during driving. Which cause the drivers worry even panic. I talked to local dealer several times. I was told to change battery everytime. But my battery and alternator were both tested fine. The message could pop up right after full charged battery. There are many complains at Volvo forums. Volvo knows the issue, but they decided not to recall it. The check engine light and messages pops up on and off by itself. The DTC codes are normally U0286 and/or B1087. I am already changed one battery. The problem is still there. It could cause accident because the message pops up during driving on highway and cause unnecessary worry and panic.
