are you asking if the Sorento will interfere with your radio? or if the radio will interfere with the Sorento? I think the only interference you might encounter might be if it's keyless, the fob might have issues depending on what you are doing. all depends on the frequencies and strength of the involved signals.

 

Cell phone have been reported to affect the immo, so some HAM frequencies may also.

I have a 2015 Kia Sorento LX and I run both a CB radio and a GMRS radio and haven't had any issues with any electrical interference. I originally had them just plugged into the cigarette lighter plugs, but have since hardwired them directly to the battery, no issues.

I have VHF, UHF, DMR and Yaesu Fusion radios in my 2017 V6 Sorento. Wired directly to the battery with an inline choke to prevent electronic noise getting to the radio. Antenna is mounted on the rear panel near the lift gate (custom mount in the gap between the lift gate and body of the car). With max wattage of 50 never had interference. HF may be different with more wattage but doubt it unless the RFI is really bad - of course if you are trying to run 1500 watts ?
Actually, if a radio interferes or the car interferes it is KIA's fault as these vehicles are used as police cruisers in many countries and should have to be FCC compliant.

Susceptibility tests are conducted using 'reasonable' limits. Dumping a KW of RF with tons of crappy harmonics due to sloppy finals near the vehicle's electronics aren't something that Kia would or should have considered in their design.

As we don't know from the OP about the bands in question, effective power, antenna location, etc., there's really no way to predict the results.

And the FCC doesn't deal in conducted or radiated susceptibility testing for vehicles (or anything else) - they only concern themselves on the emitter side. That would be a function of whatever CE testing Hyundai/Kia performs where such standards do exist.

 

Its a loaded question. The answer is pretty much it DEPENDS, on a lot of factors.
Amature bands are extremely broad scoped.

• freq and power ERP and harmonics for the ones in use are factors
• proximity of components to the antenna which require RFI shielding and/or engineering to resist side effects
• band pass filter on the transmitter maybe needed especially with high watt output.

Testing is the only way you will know as all vehicles may not be as tolerant as others.

 

I have a 2016 and I get massive interference on aviation and railroad VHF channels.

 

Of some note...

There was a recently abandoned plan by many of the auto manufacturers to scrap AM radio from their vehicles. Turns out that a primary reason behind this was the ongoing issue of interference by vehicle electronics, even at these lower frequencies. Makes me wonder if the manufacturers were somehow skirting CISPR 25 regulations since that should have limited unintentional emitters to a tolerable level.

 

@Paul B
Right on, balun, chokes, capacitors across or in series filter and/or bypass these intrustion placed in the correct place in circuits. Both are dirt cheap. AM radio been around since day one on communications and absurd to remove something so easily implemented in a product with todays circuits. I am sure there are areas where FM broadcast are very hard to get or don't exist. Norther Ontario rural areas of the Praries as well. People may not buy a brand not having it. I looked at a Honda Pilot when I was considering another SUV and ruled it out for various reasons but discovered SiriusXM was removed from their head units !!! Only specifiy models had it. LOL Why, everyone doesn't stream from their phone, I can select various feeds on SiriusXM but tinkering with a phone is distracted driving here in Ontario!!! Much harder to manage for sure.

I doubt anyone oem sound system is built by them someone makes the heads for Kia/Hyundai, GM, Chrysler etc and all subcontracted out. If you try and buy any of them outright. You'll find out the cost more than the best Kenwood or other deck out there which blows them away!! Just not a custom fit.
