Retired Bob

I have a 2014 LT and had all 4 tires wearing severally on the outside edge of the tires. I took pictures and along with a polite letter contacted the tire manufacture. I was asked by the mfg to have an independent tire dealer inspect the tires. The tire dealer agreed that the tires were wearing abnormally and they contacted the tire manufacture. The manufacture agreed and offered me a new set (4) of tires (any tire I wanted as long as it was their brand) at 1/2 price with no install costs. The new tires have worn normally. No, I choose not to identify the US brand of tires. The problem tires were OEM.

Is this the same concept? https://www.amazon.com/AUXITO-Canbus-Bright-Lumens-Reverse/dp/B07FYH2V4J/ref=au_as_r?_encoding=UTF8&Make=Chevrolet|47&Model=Silverado 1500|491&Year=2014|2014&ie=UTF8&n=15684181&newVehicle=1&s=automotive&vehicleId=1&vehicleType=automotive

Hopefully you've contacted Fluid Film directly and talked with their technical staff: https://www.fluid-film.com/

Ah so, this concept is not new (but it was to me) and may not apply to my Silverado, yet reading the excellent 'comments' above and doing a 'search' on words like "which new cars need a battery registered" or words like that will provide some useful information (mostly for BMWs, but knowledge is knowledge). Also suggestions like, if you want to skip the registration, at least get a battery as close to the original specs as you can.

Saw this 'article by Consumer Reports' on the Web: https://www.consumerreports.org/car-batteries/how-hot-weather-affects-your-car-battery-what-to-do-about-it/ <cut> In some cases, owners can replace an AGM battery with a flooded one to boost longevity in hot climates, Barron says, but it’s best to consult a mechanic first. Many cars come with AGMs to support an increasing array of electrical components, and the charge system may be configured specifically for the charging needs of the AGM. Cars and their batteries are becoming more capable and sophisticated. This can add complication to the once-simple task of battery replacement. Barron points out that some recent models from Audi, BMW, Ford, Mercedes-Benz, and others require the battery to be registered by the car, so it can optimize charging and usage. This typically requires a mechanics’ scan tool, a professional-grade device that interfaces with the car’s computer system. Even older vehicles can require some level of reprogramming by a mechanic when a battery is changed to allow all systems to work. Ultimately, this means that many DIYers may find that they need assistance from a professional. <cut>

For those with truck vibrations, possible refer your dealer to this article to see if a new request to GM following these instructions might be helpful: TAC Assistance with Vehicle Vibration Diagnosis Posted on December 13, 2018 https://sandyblogs.com/techlink/?p=10581

Push to Talk Button Operation Posted on July 8, 2018 by blogadmin The push to talk button on the steering wheel (Fig. 9) is used to answer an incoming call or activate voice recognition with the infotainment system on some GM models. However, on other models without built-in voice recognition, the push to talk button will only connect to OnStar or the voice recognition of a connected mobile phone. Fig. 9 2018-2019 Sonic, Trax, Terrain; and 2019 Encore, Regal, Camaro, Colorado, Cruze, Equinox, Malibu, Silverado, Canyon and Sierra models equipped with Infotainment 3 systems (RPO IOR) do not have voice recognition capability with the infotainment system. The voice recognition commands are dependent on the phone paired to the vehicle. The push to talk button will answer OnStar hands-free calls. This is normal operation for the IOR infotainment system. In addition, it may appear that USB names cannot be deleted from the infotainment display after a USB drive has been removed from the USB port. The infotainment system displays the last three sources on the audio screen, such as AM, FM, SiriusXM, a Bluetooth device streaming music, or a USB drive. (Fig. 10) The last three sources used will be listed even after the source is removed from the system. The name of a USB drive that was connected will be removed from the audio screen after three other audio sources are selected, such as AM, FM, SiriusXM, etc.

QR Code on Certification Label Offers More RPO Codes http://sandyblogs.com/techlink/?p=9801 Beginning with the 2018 model year, a QR code was added to the Certification label (Fig. 3) on all Buick, Cadillac, Chevrolet and GMC models. The new QR code includes the Vehicle Identification Number (VIN), RPO codes and other information that identify the content of the vehicle. In previous model years, the Service Parts Identification (SPID) label, often located in the trunk or glovebox of a vehicle, included this information.

You might consider sending an email to GM. Give them all the info (VIN #, etc) and how you use the truck (drive off-road, city, highway) and ask them what routine you should follow. If they reply, you will then have a written answer should you ever have need of proof.

GM has such a great opportunity to learn from the work/testing done by people like you and so many others responding to this subject, it's a shame they void your warranty rather than contacting your and working with you to help solve this vibration issue. Shame on GM!
