I have a thought I'd like to share. For those of you who have had your hood fly up, did you have a radar detector installed? Radar detectors these days are very powerful and in addition to detecting signals, they transmit signals as well. We never heard of the frunk issue while the test mules were being driven. Why? Maybe, just maybe, because they were not allowed to use radar detectors! Maybe the signal the radar detector transmits is the same, or close to, the frunk remote control frequency?

Since radar detectors have an oscillating current, all radar detectors not only pick up radio signals, they also transmit them. This means that any radar detector, whether it has a jammer or not, broadcasts a tell-tale radio wave whenever it is turned on.

In areas where radar detectors are illegal, police may be equipped with a device called VG2. The VG2 instrument is simply a high-powered radio receiver tuned to the frequency of the signals emitted by radar detectors. So while you're scanning the area for them, they might very well be scanning the area for you.

Another possibility is today's radar detectors take a lot of power to operate. Is there some type of backfed energy that goes back into the fuse panel and interferes with fuse 18?

I'd really like to know if any of you who have had the frunk issue had a radar detector installed?

Just some thoughts.

a key fob runs at around 911 MHz, I don't think radar detectors emit on the same frequency.

Shouldnt matter as far as the remotes because unlock functions are disabled by the BCM when the car is moving.
The CAN-Bus may be another matter. Say you wired detector power into a CAN_Bus wire thinking its just plain power.... no bueno.
Would it cause the observed behavior? Unknown.

Radar operates on:: 8-12 GHz, 24 GHz, and 33-36 GHz

Radar detectors put out very tiny amounts of RF energy--they try to put out as little as physically possible.

This theory can be proved/disproved if we could some of the victims to say whether they had a radar detector in their car or not.

This, more likely (but implies a striker wire breakage):

Would not have to break, just not be heat treated properly and not be as strong as designed and friction in the systems prevents it from fully latching or staying in the fully latched position!

GM probably has had some of the latches that caused the issue in their labs etc. We'll see what they find.

My theory is stray Tachyon pulses.

Interesting thoughts, I was thinking it was the button in the front malfunctioning. I was wondering did you ever get a C8 or going Z06 or just doing the Lamborghini thing? I am in the search for a GT3, or something exciting with a manual.

No radar detector plugged in when m hood popped open.

I’ve had a uniden R3 in my c8 since the day I brought it home. 3,000 miles now and no trunk openings.

Perhaps its tied to the way the emergency release for the frunk works. If it is pushed and the car is above a certain speed it will not open all the way, preventing the escapee from jumping out at high speed. Once the car slows enough it will open completely allowing the victim to safely exit the frunk. If a load shifted and hit the button it might not release fully until you were near a stop. Then when you took off again it would fly open once you had enough speed. I'm certain it should throw frunk ajar warnings. I think GM outsmarted themselves on this one, just make the frunk emergency release a simple pull handle instead of an electric button, you already have the mechanism in place for if the car loses power. That way you don't have to maintain battery power to the switch. Just a thought.

A front-hinged frunk-lid, in the original design, as with others... no catastrophe if it came open at speed.

Yep, reminds me of my computers! Type too fast and they remember the key strokes but only apply after whatever the CPU is managing after the time is finished and you wind up with three on the screen because you hit that key 3 times wondering why it's not coming up!

Yep could have used the simple mechanical safety latch I have had on all the FE cars with front opening hoods in the past 60 years! Could not remember for sure what I did on my '62 and '67 Corvair Frunks but found a video!

Thought so, we used a thing called a key! Didn't have a foolish thing like a child opening safety- but kids then didn't need such foolishness because were smarter! BUT today, since required by law, could have put a simple pull handle on the mechanical safety latch with an LED so they could find in the dark! Note from the video the Corvair had that 2 stop latch as he said his wife often engaged by turning the key half way!

We needed a 10th thread on this?

Panfish

Hope it gets definitively solved before the first fatality. After that, the game changes completely...especially considering the history.

C8-Vette

Watch what you put in the storage compartment on the drivers door. Yesterday I put my cell phone in and hit the frunk button. (i dont use the cell charge spot on the console)

theblackangus

Thanks!
Btw - Did you have any modification at all on your car, was it 100% stock? (I'll bet the answer is no, but this also rules out other types of modifications if many of the people with issues are completely mod free)

theblackangus

While this shouldnt open the frunk either. I would agree that it was a bad design decision to put it there.

range96

I guess you could also inadvertently push the button as you CLOSE the door...

If these happen I would expect a transmission interlock to not allow gear selection UNLESS overridden by a user action. And there lies a well designed and safe user interface we could all live with and love.
