So much three time this week the factory alarm went off in the middle of the night. This taken place before and the problem just walk away. I have actually pulled the fuse for the horn so I deserve to at least gain some sleep.

Beware the hood sensor and tail door sensor - both are most likely suspects.I"d it is in interested even if it is you paid any special fist to the dash lights as soon as you went the end to disarm previously, or go you simply use the fob without acquiring in and checking the dash? There"s no one-of-a-kind indicator for the hood, but there is for the tail door if it"s still no latched by the moment you gain there. Sounds favor it"s much more likely when it"s colder, so when it is, but when the neighbors aren"t likely asleep, it would certainly be worth trying to provide a an excellent yank ~ above both the hood and also the tail door to watch if you have the right to trip the sensor on one of two people while they space (ostensibly) latched and collection off the alarm. Neither should respond..
I tried pulling on every doors hood and also tail gate and could not trigger the alarm. Ns did no check any type of of the dash lights. In ~ 2am my first goal was to revolve off the alarm.

I had the same problem with the alert going off randomly after that rained. Traced the problem to negative battery cable connection to the painted fender well. The link was thru 2 tiny screws the to be corroded. I scraped the repaint off and also cleaned the screws to deal with the problem. This additionally also addressed intermittent problems with external temp display.

deespersonIndeed, that negative ground can reason a entirety host of exciting gremlins, though ns think this is the first time we"ve heard the the alert system deserve to be one of the results. When Hyundai does no recommend scraping off the paint, ns do. After chasing the threads, cleaning it up, and taking off a bit of paint under the lug, simply be certain it"s goobered up with plenty of your favorite product that will prevent any kind of corrosion after ~ the fact. I regularly mask turn off the area and hit the with one of the commodities used because that "painting" battery terminals. Others use various species of grease.

I scraped the repaint from the ar where the an unfavorable cable joins the body, coated it through grease, fastened the lug and then an ext grease. I don"t know about any other effects, but it beginning quicker!

I had actually the same night alarm went off, uncovered the hood lock sensor to be wrong.Alarm system went off when the hood lock sensor detect the hood was open.Instead of change the sensor, merely I disconnected the sensor cable connector located just under the hood lock.
I thought about that together well. I disconnected it and it was fine because that one night yet went turn off the 2nd night. It would be nice if somehow you have the right to identify what sensor is triggering the alarm.
