  1. i30 & Elantra Touring Forum
    My cruise control is behaving very odd. To turn the system on I must press the CANCEL before I press the CRUISE button. Then to engage the system the SET button doesn’t work but the CANCEL button gets it to activate. The increase and decrease buttons sometimes work but also sometimes role...
  2. PHEV (2022+) Tucson
    Hi, I love adaptive cruise control, but recently I was in a traffic jam that had me going 70 mph and ahead of me was a complete stop. I didn't trust this feature, so I hit the brakes manually. Is this something that's supposed to work? Because it's pretty terrifying to leave braking at high...
  3. MD (2011-2016) Elantra sedan/coupe
    I've looked through several sites and posts and haven't found an answer, so I've come to this forum to see if anyone can help. I recently purchased a 2011 GLS Elantra. It's been a good ride, but there's one snag that I haven't been able to resolve. All of the buttons on the right side of the...
  4. ix20
    Hello and welcome, in this guide I will try to explain my best how to install cruise control on your hyundai ix20, as well as what is needed and if your vehicle is capable of retrofiting the factory cruise control system. First, let me explain my situation. I got my ix20 this summer from my...
  5. Y2-EF(1989-2005) Sonata
    03 Sonata 2.4L I have a weird issue that started post Covid due to driving a lot less. If I leave my car for a week, the cruise control master switch does not activate unless the car has been driven for about 4-5 hours, after which, it will just turn on, and the rest of the cruise control...
  6. LF (2015-2019) Sonata/i45
    Sorry for the long read, trying to provide as much detail as possible in the hopes of solving this problem! After about an hour of highway driving, my 2018 Sonata Limited chimes and shows "Smart Cruise Control Disabled. Radar Blocked" and then "Autonomous Emergency Braking Disabled. Radar...
  7. Sonata All Hybrid Models (YF/LF)
    When pressing resume the cruise control will sometimes bring the engine up to 100% power on level ground (even when there is no hill to climb). Has anyone had this issue addressed and resolved?
  8. i30 & Elantra Touring Forum
    Hi everyone, Last week the radar on my MY2018 i30 SR stopped working due to heavy rain, and since then the warning lights to check AEB and check adaptive cruise have been on and neither of these work for now. I have booked the car in to be looked at, but before then I am planning to go on a...
  9. General Hyundai Non-Model Specific Discussion
    I found that the Cruise Control in my 2014 Sonata is calm and accelerates gently. Even up hills it doesn't rev like crazy. However, my Sonata was in the shop for a few weeks back in August for the engine recall, and I got a new 2020 Elantra. The Cruise Control acted completely different. I...
  10. H-1, H-100, Starex & iMAX Forums
    Hello, I own the 2010 Hyundai Grand Storex diesel in Korea. I'm hoping to equip my grand storex with cruise control because of frequent long-distance driving but unfortunately my grand storex is the type that does not support cruise control in normal ecu, so I'm inevitably pondering aftermarket...
  11. LC (2000-2005) Accent
    My 2019 Santa Fe seems to have a serious cruise control problem. Sometimes it works. Sometimes it doesn’t work. Today, while driving on the freeway, it detected a car on the right front fender that wasn’t there and slammed down the brakes. Scared the crap out of me! Is this common?
  12. RB (2012-2017) Accent
    I apologize in advance if my questions have already been asked and answered. I want to retrofit my US spec 2015 Accent GLS with steering wheel mounted cruise and audio controls (but NOT Bluetooth). I’ve read many posts about adding a wiring overlay for the cruise functions. I do this kind of...
  13. Genesis BH 2009-2014
    My 2009 Genesis has been an very reliable car until about a month ago. The a/c has been used very heavily for 10 years and it was blowing air that wasn’t cold enough to be effective. I brought it to a very reputable garage and they had to replace the compressor. The problem now is that ever...
