NHTSA Complaint #11601451 — 2013 SUBARU IMPREZA

In the morning of 7-11-2024, I started the engine to go to work as usual. I found the engine light on and noticed strange symptoms from the hood, such as unusual loud noise. Thereafter, I lifted the hood and confirmed loud noise coming from somewhere. Then, I immediately shut down the engine (no key in ignition), but still, the secondary air pump kept running. I thought it may be blowing up, so I immediately disconnected the battery. I touched the pump and almost burnt my hand. I did do this immediate action because I have some experience/knowledge on car maintenance, but I feel terrible if this happened to someone else, such as young drivers. Then, I googled for the similar symptoms, and found something matching my symptoms in the recall notification letter (NHTSA recall no. 16V738), in which the relay in fuse box can cause the issue. The letter appeared to be revised in 7-11-17, and it was supposed to be sent to me, but I did not receive this important letter at all. I think that this letter should be re-sent to all the owners again to avoid possible terrible incidents related to overheating of the secondary air pump.
