I've been around and driving GM cars my whole life. My father was a General Manager of a number of GM dealerships over his lifetime. GM radios always had excellent FM reception able to lock onto radio stations that others couldn't. Of course that's when the GM radios were made by Delco. Turns out Delco has a unique and optimum way of tuning FM stations (see the article "FM Tuners: The Present State of the Art of FM Reception" in http://www.biline.ca/audio_critic/mags/The_Audio_Critic_23_r.pdf . It's rather technical so not for the laymen.). This article is old but it gets the point across. GM needs to rethink their new vendor selection for the radio tuner.

 

I haven't gone to my dealer with this problem yet. I plan to when I take the truck in for the next routine maintenance. I'll hit up this GM Customer Service Representative as well for the hell of it.

I have to strongly disagree that GM tuners have always had "excellent" reception. My 2002 silvy had good reception but I also owned a tacoma and a jeep during the same time period and both would pick up stations that were further away than my 02 model would and the closer stations would be clearer on those vehicles.

I just signed up to see if there is still interest in this topic? I'm currently doing some testing on the 2016 radio that seems to be somewhat deficient on FM and a little on AM.

OK. I've done some testing and I'm going to do more. I've been in love with automotive radios since my Dad's 1956 Buick, his first car to have a radio. I hope to attract some engineering minds to this subject to fill in what I don't know so as a start, anybody that is interested might want to review the AMAX standards that were developed for stereo AM, there is a Wiki on it if you search "amax radio", and the NRSC-1-B standards for radios, pops up as a PDF on a search. If some of you are used to the new as well as the old radios, you'll notice the difference that these standards have made in radio performance.

 

I've been chasing poor radio performance problems for a few years now due to the 2007 Pontiac G5 GT that I also drive. It has a rear mounted antenna mast which causes similar problems to what I'm experiencing in my truck due mainly to the long length of shielded wire from the antenna to the radio. This results in increased capacitance in the "lead in" wire shunting or attenuating the signal from the antenna. Driving me nuts. I've improved the AM reception by adding a top hat to the antenna but I'm going to try an FM antenna preamp to improve the FM. This radio is not usable on weak FM stations. I've never heard a lot of complaints about these so maybe people are just getting used to poor performance, or maybe I have a really bad one. If you lived in a city with this car, you would not have noticed a problem.

 

The Pontiac problems may not apply to the Silverado radio problem just yet, but my testing shows that I may have a problem in my truck's antenna. I also found that maybe 2 feet of 100 Ohm coaxial cable, the Silverado antenna wire to the radio, is coiled up just under where the mast is mounted in the engine compartment. There is even a sticky cable holder mounted there to hold the excess. I would like to know if others have this on the 2014 and 2015s. This cable also measures 165 pF, (pico Farads), where a 5 foot cable should measure only around 68 pF. I've tested a 2001 GM truck radio connected to my 2016 truck antenna and, standing still, the FM sensitivity appears the same, AM a little better on the old radio. I have provisions to test them with a signal generator but didn't have time yet. I'm going to drive 25 miles away from the city transmitters today so I'll post the results when I get a chance. I don't have a lot of time to devote to this so bear with me.

 

Disclaimer: These are my opinions as the result of my testing on my vehicles and using my equipment. If anybody has any suggestions, please speak up. If I'm doing something wrong please tell me.

 

I understand how annoying a bad radio is and I would like to find out why it is bad or what is bad. I've owned my truck since February and have less than 3000 miles on it. I have a notice of a software update available to add an Android music app but haven't had that done yet. I have not complained to the dealer yet since I've read of the results of that, very little success. Maybe some of the guys with the 21014 and 2015 trucks can take a test drive and try the radio in a 2016 to see if the problem is the same. From reading the posts, some of the 2014s are really bad and maybe some are good or the owners just live near a city, probably impossible to sort that out.

My trucks have bad radio reception. One is worse. Lose hd signal 10 miles from the big city and the complete station within 15 or twenty miles. If traveling on vacation all you do is hunting for another station. Had the update and new radio put in my dealer but did not help. Asked GM for lifetime Sirius radio with no luck.I am now paying for Sirius. Works good. This issue is not important to GM just like the bad headlights. They wil not get another purchase from me and I tell anyone who asks about my trucks.

If GM got rid of HD in the '16's, that wouldn't be a good comparison..........right?

      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.
