I just spoke to a rep from Furrion who was nice enough to return my support email with a phone call. Furrion is the manufacturer of the observation camera on my trailer.

 

This is definitely not a wireless interference problem. It is a GM power supply problem.

 

They have been getting dozens of reports of this problem with the Chevy/GMC 2019 trucks. From what they can determine, the "smart" power supply on the truck is not providing enough voltage or current, as many of you have suggested. Testing the voltage directly at the truck 7-way appears fine, but when you plug in your trailer, the "smart" feature kicks in and causes the problem. 

 

Keystone and some other manufacturers wire the camera to the running lights. Some other manufacturers do not, which is why they aren't having the problem. 

 

Furrion engineers are trying to find if there is a way to trick the truck into providing the proper amount of voltage and current. I am going to try some experiments of my own to see if I can come up with anything. 

 

The solution for now, is to hard wire the camera to the battery of the camper, as many of you have suggested you can install a manual switch or a relay tied to the running lights,  to power the camera. It is a pain to have to re-wire it, but it is a solution.

I may be facing the same issue with our trailer next month. We have a Lance trailer with rear-facing camera and dash monitor that plugs into a power outlet. Works well in our 2012 Silverado, but we're

Phil, you are sort of correct; a) is the key factor. With the trailer connected to any other vehicle, the system woks perfectly. With the trailer connected to the Silverado, the system won't work even

I am having the same issues with my Furrion camera on my 2019 Silverado. The problem is the Silverado uses a PWM signal on the trailer light circuit and it interferes  with the camera. Furrion is aware of the issue and supposedly working on a fix.

We purchased a  Furrion FOS07TASF 7" Vision S Wireless Vehicle Observation System: 7-inch Monitor and 1 Rear Sharkfin Bracket Camera from Amazon.  Not cheap!  We installed it in our Airstream ourselves and took every precaution to do it right.  It worked with our 2016 GMC Canyon PERFECTLY.  We took it on one trip and when we returned we traded the Canyon for a 2019 GMC Sierra 1500 Denali.  Camera WILL NOT WORK!  We are so frustrated.  It will pair when paired with the pigtail in the truck but even when the camera is on the back of the Airstream and the monitor is AT THE BACK of the Airstream (inside and plugged to 12 volt) it will not pick up a signal.  We are baffled.  We have spent hours (lights are on, etc), have unpaired and repaired... no picture and no signal.  Amazon says the "return window is up" (less than one month).  I guess a Voyager will not work, either?!

UPDATE: My husband and I have never received such customer service!  Furrion's "head of customer relations" called my husband and their engineers have a fix for this problem. It is a simple plug in that they have tested and it works. It plugs in the 7 way and boosts the voltage to the camera (ours is wired to our running lights).  To top it off they are overnighting it and sending it free. We are overwhelmed with the service.  It is not their issue (it is GMC's) and yet they have worked out a fix.  Rarely, if ever, have we had THIS sort of exemplary service.  Will update again when we receive and test the adapter. GMC, if you are listening (and you should be) why not RUN on over and patent this adapter now from Furrion?!?!?  (I have no affiliation!)

I have a Haloview MC7108 and ran into the same problem. I contacted Haloview and they're sending my a "boost module" to test. I don't have any more info than that so far, but I'll post an update after trying it out.

I got the module from Haloview, it's a small box that plugs inline to the power cord for the camera. Using my meter I measured around 10.2 volts at the marker light that I spliced into for power and the module brought it up to 14 volts. The camera powers up after a few seconds of turning on the lights and it worked fine for my first trip (about two hours from home. If anyone else with this problem has a Haloview I definitely recommend contacting them to get a module.

Furrion is now working on an adapter that fits in your 7 way.  It took care of our problem.  They sent us a prototype and we drove over 6,000 miles without a blip!  Contact their customer service department.

I’m with ASA Electronics and Voyager® is one of our brands.  In 2019, GMC & Chevy Trucks started using a PWM (pulse width modulation) power supply for trucks equipped with their smart trailer app that checks for trailer connection, light fault detection and security functions.  This PWM power supply is feeding the trailer light circuit and is what causes the camera to cycle ON/OFF continuously. 

 

We have been in development of an in-line filter solution for the past few months that will accomplish several things:  provide correct camera operation on the existing trailer light circuit; be small enough to pass through the existing hole for the camera cable; and not create any fault codes for the running lights within the trailer app.  As part of our existing relationship with GM and our iN·Command® Control Systems, we have been working directly with GM for testing.  We chose to filter at the camera rather than at the bumper connection as that would render the PWM light fault detection on the tail light circuit inoperative.

 

We are still validating this part and should have a launch date to announce in the near future.  I’ll be sure to update this thread when these modules are available and where to find them.

 

**UPDATE**  our filter is available for those that need it to solve the PWM issue.  There are two versions, p/n PWMBUT and PWMCEC, with the difference being in the connection type.  Our Voyager cameras ship with our CEC connector; however, in some applications this has been removed and have only the +12V (Red) & Ground (Black) wire connected to power source.  For these, the blunt-cut version is used.  For those with our CEC connector, the Voyager CEC version is needed.

Please consider that most cameras are mounted without a plug near the camera.  Having a dongle hanging from an Airstream rear camera would not be an appropriate fix.

Our solution will be inline with our proprietary CEC camera cable connectors.  On the trailer, the camera goes into the outside wall and meets the disconnect (male-female).  Our module is going to be small enough to insert through the existing hole on the Airstream trailer.  You will only need to pull out the existing cable, unplug and connect the new module inline, then push the module and cable back inside and reseal the hole.

I have the same issue- i purchased the 2019 trailboss earlier this year and only to find out after the fact that GM has not released any info to 5th wheel trailer manufactures on the new frame design and i could not mount a 5th wheel unit sometime in 2020. On top of that my 5th wheel also has the rear camera that will not connect and according to GM factory reps it is because of the software platform they are using and there is no fix. so i paid all the money in the world for whats supposed to be the top of the line CHevrolet product but in return GM has not done their research on the growing RV industry. I am stuck as the dealership is at a loss and the factory reps are no help!

I’m having the same issue on my 2019 Sierra SLT, which I bought specifically with the 6.2L engine to tow our camper that we can’t tow safely now. GMC is no help at all. The dealership is no help at all. Maybe it’s time for a lawsuit.

Is there any way to get updates on this?  Some of us would love to get a fix for this issue.

You do not need a back-up camera to safely tow a camper.  People have been safely towing for decades without them.

True, but it’s much safer to have one. I’ve seen plenty of examples where an accident would probably been avoided with one.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
