Radio static

Hello

I have a 2019 with the Bose audio and ever since taking delivery 3 months ago I get static on many radio stations. I even get static on Bluetooth when talking to someone. The static can range from slight to almost full static to the point you can’t even hear the music. I took it to the dealership a couple of times and just this past Friday they replaced the amplifier under guidance from technical support from corporate. It didn’t fix anything and in fact may have made it worse. Has anyone else had radio static issues or any issues with their radio, speakers in general?

Under warranty, let them replace the whole radio. Depending on your states Lemon Laws, bringing it back for the same issue multiple times and you are in Lemon Law territory. Check your state Lemon laws and let the dealer know you are ready to pursue it, it's in their best interest to correct it.

I wouldn't even take the time to take it to a dealer......as F.G. says "Crap is as crap does".



Curious, replaced the main Bose amplifier or just the antenna amplifier? Regardless - Of course a new amplifier didn't fix the problem - a new antenna amplifier won't either - these new gen radio/Nav heads even with the $1000 Bose system and amplifier option have crapo front ends (worse than my gen1) that require a strong signal to work properly. They even contain an antenna amplifier to boost the signal which I figure amplifies more noise than signal. I'm in the same boat living in a mountainous fringe area. A far cry from GM's predecessor radio/Nav head in my '16 Silverado whose $500 Bose system has a really strong front end - even has the HD radio feature - can almost pull in signals from Mars. Plus it can play mp4 videos via USB on the front Nav screen when parked whereas the '18 plays dumb and cannot find the same files.


Could also be an effort to save bucks on a cheaper radio or maybe to pump up sales of the XM service. Use locals stations for news only, otherwise load your albums on a chip and forget the radio.

Lemon law?.... only works when the dealer cannot fix the problem on repeated attempts. Surprised he even tried. Can't repair acrap[ system only replace with another piece of crap radio and still have it sound like crap....working exactly as designed.


Any complaint based upon something so subjective as listening quality, dependent upon the station, power output of the station at the particular time of listening, intervening topography, hearing acuity of the listener, etc. won't get you past an arbitration board relative to a complaint challenge - in fact probably give them all a good laugh.

The part that they replaced was the radio speaker amplifier.

Part number 84503667

Also to subjectivity I understand what you mean but I had a Ford Edge, a Chrysler, a Toyota Prius and other cars and never had static. I have traveled the same roads with the traverse and the static I have is quite severe. Even yesterday a station was so full of static that it just went silent. When I toggled to another station it was fine and then back to this station it was dead. Have it all on video. The dealer does not seem to know how to fix it and I would just like to use my radio

You have any devices installed in the car? Like dashcams or other electronics?

I use to have an issue with my HU on my previous car and I realized it was a dashcam I installed at the rear windshield to record out the back, whenever it turned on, its proximity to the roof mounted antenna would cause static and interference on terrestrial stations.

Excellent point. Many accessories can generate electromagnetic interference, even ballasts on some aftermarket lighting systems can cause feedback through the power supply system.


As far as weak radio signals and drop outs go the key component is the antenna which is where the gen2 s fail.....even the gen1s had a mini whip on the roof. These roof "wart" antennae might be great for XM and GPS microwave frequencies but they stink for FM where you need a rod antenna with a length designed to receive at least the length of the modulated frequencies. Then you wouldn't need an antenna amplifier which introduces more noise than signal......couple that to a radio with a weak front end and poor discrimination between stations and the signal will fade and pickup loads of interference. As I said my Silverado works great even with no antenna amplifier, because it has a 3 foot long steel rod real antenna mounted on the fender and no aftermarket wireless accessories to screw up reception.

Thanks all for the replies. Unfortunately I have no aftermarket additions anywhere in the car outside of my cellphone. Not sure what the next step should be. Don’t want them to pick apart the car to no avail.

Anyone have any suggestions?

Just a thought but I had a problem with inconsistent XM reception. I found the XM cable crossing (or very close to) the radio antenna. Once the two cables were separated slightly under the headliner near the wart antenna my problems went away. I don't know if the inverse was happening as I didn't listen to FM that much but maybe the XM signal can interfere with the FM signal. Like I said, just a thought.

Lucky you found it, very unlikely the dealer would have found that one.



This is a problem not just for radio signals but for many of the communication cables in the gen2 fly-by-wire systems. improperly bundling cables can lead to cross talk and introduce electrical gremlins that defy diagnostic attempts. Careless cable routing problems are nothing new, bundling the spark plug cables in parallel instead of returning each to its place in the standoff loom on the old V8s would induct a current and cause plug misfires.
