2017 Hyundai Sonata: key fob or push-button start problems

Filed Feb 20, 2026 · Electrical · WA

Here is your updated review with that included: ⸻ I am very disappointed with Hyundai Motor America and the service I received at Hyundai of Renton. I own a 2017 Hyundai Sonata and received a letter about a required software update and ignition cylinder protector due to known theft issues. I went to the Renton dealer for the recall service. They performed the software update and were supposed to install the ignition cylinder protector. Unfortunately, my car was later stolen because of this exact issue. The ignition was damaged during the theft, and I had to replace it myself just so I could drive the car. When I returned to the dealer, they refused to install the ignition cylinder protector, saying the ignition was broken. It was broken because of the theft — which happened due to Hyundai’s known defect. After the recall software update, my key fob also stopped working properly. I went back to the dealership, and they refused to fix or properly reprogram my key fob. On top of that, the service manager, John, was very rude and unprofessional. This has been the worst experience I’ve had with a vehicle and a dealership. Because of this situation. Very disappointed.

The contact owns a 2017 Hyundai Sonata. The contact stated that the trunk failed to open with the key fob or while depressing the trunk release button inside the vehicle. The dealer was notified of the failure and advised the contact to take the vehicle to their location to be repaired under warranty. The vehicle was taken to the dealer who advised the contact that she would be responsible for the cost of the diagnostic test and the repair because the vehicle was out of warranty. The contact received a recall for the federal safety agency Campaign Number: 21V619000 (Latches/Locks/Linkages). The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was 61,000.

The car was stationed in my garage, came home from shopping, hit the trunk button on my key fob, just starting hearing some clicking noises, tried to press the the truck release from inside, continue to hear clicking noises. I had a mechanical to look at it, they had to pull my seats in the back down to look inside the trunk and they said it look like a malfunction on the trunk box inside.

The trunk latch would not open. It would not respond with key fob, interior button, button under the handle or with the key. Forced it open once and then had to force it closed. Stayed closed until repair could be made. Hyundai would not cover cost or repair. There was no damage, short or anything else that would explain why this part failed except for cheaply made plastic part that wore out.
