#ElectricalIssues

While alchemy has famously spent the better part of recorded history trying to transmute lead into gold, the automotive industry has repeatedly managed to achieve the lesser-known act of sorcery where water is converted into fire. This usually occurs when humidity ends up corroding an essential electrical component, resulting in fire risk that becomes the deciding factor in a recall campaign.

This week’s corporate conjurer is Nissan, which has decided to call back 793,000 Rogue SUVs in the United States and Canada.

Sajeev,

Tonight, while driving on the interstate, the tire pressure warning light came on in my ’15 Honda Fit, then the ESC light came on, then the power steering warning light came on, and then the info display said to check the charging system. Everything seemed to be working just fine, though. I pulled off to check the serpentine belt, which was intact so I started searching on the internet for the symptoms.

According to the forums, it’s sort of a known problem that’s due to glitches in the electrical system causing erroneous fault codes. Dealers usually try replacing the alternator, which doesn’t help. The alternator harness, the ABS sensors, and the injectors/coil packs have all been mentioned in the forums as fixing the problem.

I’ll check all the connections in the morning, but in the meantime I’m leaning towards a faulty ABS sensor, since those are used for the TPMS in my car, not an actual pressure transducer, and the first light that goes on is for tire pressure. Also, the check charging system warning was intermittent.

What do you think?

Toyota announced a recall of roughly 49,000 vehicles in the United States on Wednesday. Affected models include the 2016 Toyota Prius, the 2016 Lexus RX, and the 2015-2016 Lexus NX crossover. The safety issue involves the airbag systems that could fail due to an electrical problem.

Unlike the scary Takata recalls, the biggest danger here is the non-deployment of the front or side-curtain inflators. Toyota claims an open circuit could develop within the system’s sensor. If this were to occur, the airbag warning light should illuminate to indicate a failure.
