Hood Sensor/Alarm

[HungSloth]

Hello,

I currently have a 22' G70 3.3 and i think my hood latch/sensor is failing. The car/sensor thinks the hood is open when it is not. This can be pretty annoying to drive around with since its constantly beeping at you, this also prevents me from actually arming the alarm system on the car. I called two local dealers and the earliest appointments available are more than a month away. Does anyone know any fixes or work arounds i can do in the mean time? Will disconnecting the sensor remove the alert? Is replacing the latch assembly easy?

I really don't want to wait over a month.

Thanks!

Are you certain that the hood ajar switch is in the hood latch assembly?
On the 2018 G80 (at least), it appears to be a separate switch that is at the front on the right side (your left if facing the front of the car). Unplugging it should result in it showing the hood as always open, not closed. Normally such switches work this way so that someone cutting a wire won't disable the alarm feature, but will trigger it instead.

All newer vehicles have it integrated in the latch assembly, and you cannot adjust the sucker. But it's a super simple switch, so I'd remove the shroud, and investigate what could be amiss. But up to you. I'm sure the switch could be replaced, but not sure if it's sold separately or not. However, what you could do in the mean time, is disconnect it, and bridge the connector with a clip or something, so it thinks hood is closed all the time. But I'd definitely want that fixed, since I open the hood all the time. Good luck.

Hello,

Any luck fixing this?

I have the same issue with my GV60. The dealer changed the latch assembly but the problem was only fixed for few days before the akarm was acting again.

Thanks

FYI - I also have a 2022 G70 3.3 and just had the same problem. It was parked outside (undriven) for 4 days while my driveway was resurfaced and after I moved it back in the garage Saturday I got that same horrible alarm. I waited another day to call the dealership on Monday, and by then it had gone away. I assume it was caused by excessive condensation or something - Had some rain and a very dense fog.

This is not an answer to the poster. However I had a different vehicle in the past which woke me at night with the alarm and after the second time I consulted the owner forum for that model and found moisture at the trunk latch was the issue.

I just had this issue. To the left hand side of the hood latch (looking down from the front of the car, so passenger side), there is a small switch with a steel contact tab just under the latch. Under that steel tensioned tab, there is a button. When the hood is open, the tensioned tab is pushing down on the button, and when it is closed the tab is released allowing the button to pop back up. My issue was that the button was staying depressed even when the tensioned tab was released when the hood was closed. I was able to pull up the tab and then pull up on the button, and the hood alarm turned off, but only for a few minutes. Eventually the button fell back in to the 'hood open' position. By this time I was pi$$ed, so I bent the tab back, tore off the rubber jacket over the button, tore the button off, pulled the spring out, and under there was another smaller button. There was nothing I could do with that smaller button, it was buried inside the switch. There is no connector from the switch to the wire, it is one complete assembly that seems to disappear under the passenger side air intake filter. So, I just cut the wire just under the switch. Open circuit = closed hood. I pulled back the sheath to expose the two wires, put some heat shrink on each wire to keep them separated, then taped it all up with electrical tape, and then tied wrapped the cut wire to the hood latch. Alarm is now off, thank god.

In order to do all of this, I had to take off the 4 bolts holding the latch on the car, which allowed me to flip the latch around slightly so I could access the switch.
