Trailer Cameras Not Working

Here it is- April 19, 2021.  I spent the whole day at the GMC dealership.  GPS doesn't work or is intermittent.  Rear trailer camera doesn't work or is intermittent.  I have had this problem for some time since it was new- July 2020.  The technician said there was an GPS error code and replaced the GPS antenna.  It worked great when I left the shop- but failed before I got home.   I called the service rep- He said push ON-STAR.  I did a welcome call- bingo- GPS started working.  Sample of 1 time.  We'll see how well this works.

 

At the same time I noticed the trailer brake lights after locking the truck with the FOB.  This is the theft deterrent mode.  The lights were flickering... I unlocked the truck and re-locked with the door lock.  The lights behaved normally with a single flash every 30 seconds or so.

 

The techician said there was an error code for the rear camera.  They will order another one. I'm not optimistic at all.  The whole Infotainment system is very complex with complex firmware.  Seems like there is not sufficant diagnostic error catching codes to trouble shoot problems.

My quess is tomorrow I will check out the camera and it will work.  If it does, I still lose the calibration.  That means I will need to remove the rear trailer tire to re-calibrate.  YES- It doesn't calibrate with the rear tire mounted.

These problems need to be elevated to higher hardware, software and firmware engineers. How can they fix these things if they are not in the middle of the trouble shooting battle ????

I hear the camera can be used as a simple rear camera without using the transparent trailer feature.  I have a 5th wheel so it won't work anyway.  Has anyone done this and how do you program it or does it even need programing?

You can use it on any trailer as just a backup camera.  Just plug and play if your truck has one of the systems that accepts trailer cameras.

So i have been all over the internet trying to find some guidance. 2020 Silverado with trailer camera package (no the invisible trailer). FIRST camera worked intermittently. Sometimes it shows connected, sometimes connected by no option for the camera in the camera screen, sometimes it worked. It finally failed completely.

 

Second camera, same thing, except I have never been able to get video. It shows connected, but that's it. My dealership is clueless about this option. I am very frustrated that I bought an option that should be plug and play and am getting no assistance. I too have tried every combination of plugin procedures, asleep, hot, everything. It is a very nice function when it works, but it is very sketchy. My dealership wants me to bring the RV in so they can install it ($$). I don't want them anywhere near my RV after their displayed knowledge of the situation. I'm at the end of my rope!!!

Have you tried plugging your trailer into the in-bed connector?  If you have an in bed connector.  I got mine installed last week on my 36' 5th wheel and it's working great.  It seems to know if you use the in-bed connector that there is no invisible trailer as it won't even let me go into the setup for it.

I have a 2020 GMC 2500HD Denali with the Trailering feature.  I had my GMC dealer install the rear trailer camera on a new 2021 travel trailer.  They did a great job.  It worked intermittently for months and would lose calibration.  I had to take it back to the dealer many times to have the technician troubleshoot to problem.  Finally, they replaced the camera.  BINGO.  All has worked perfectly for months now.  I'm thankful I had the dealer install and backup the warranty.  There may be a reliability/yield issue with camera.

 

The only problem with the GMC now is the GPS.  It has always been intermittent since new.  The California Lemon law is being persued.

I'm not even sure I have in-bed connectors. I don't have a camera right now as I sent the new one back, and am trying to get some resolution as to exactly what's going on. I.e., is it the camera or the truck. I might try another camera at some point, but right now all I have is frustration...:banghead:

I bought my 2020 GMC Sierra AT4 brand new. With a complete camera system, camera never worked. GMC did nothing to help. Trying to find another wiring harness and connector so I can rewire the camera to see if I had a faulty wire but I can't find the parts. Hopefully an aftermarket part if they're available.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
