2019 Hyundai Tucson

My 2019 Hyundai Tucson repeatedly shuts off while driving , without any warning. It rolls backwards while in park. The car could easily hit me taking things out of the trunk or hit my neighbors walking past my drive. The car has no power. It can’t get up to speed. It shakes and I have to get someone to add oil to it frequently. The first time this happened was in April of 2023. The engine seized up and it was towed to Driver’s Village in Cicero, NY. They replaced the engine block. But not the converter. Now, it is happening again. I have had 2 diagnostic tests done. One by my mechanic and the other by Advanced Auto Parts. Both tests say that the problem is the catalytic converter, but Hyundai refuses to fix the problem and will not honor my extended warranty. I have written and called them numerous times for almost 2 years now, about this and they say they will call me back, but they do not. None of the dealerships will even look at my car. I need someone to look at my vehicle. This vehicle is not safe. Other Tucson owners have the same problems with their cars, that I am complaining about. There is a federal emissions warranty that Hyundai claim they have never heard of, that would fix my car and make it safe to drive. I just want Hyundai to stand behind their warranty and fix my car before it kills someone.

Our Tucson was stolen in Charlotte, NC on [XXX]. The pax rear window was broken and the thieves broke open the steering column to start the car. It appears they used the well-known "Tik-Tok" method. I have record that our Tucson had the "software update" installed, at a local dealership, a year ago. This update (which should've been a recall) was supposed to address this issue. Despite this update, the car was stolen in less than 2 minutes (I have Ring camera pictures with timestamps). I have doubts now that the dealership actually did the update. Part of the update includes a specific window sticker that is to be applied to the driver's door window. That decal is missing. There is no evidence that it was ever there (I have pictures). The car was recovered but cannot be driven. It must be towed due to the damage. Another concern is the engine and drive train. Criminals were out joy riding in our stolen car on an almost full tank of gas. Because the car cannot be driven, I don't know if there is any damage to any part(s) of the drive train. We are now waiting for our insurance company to arrange to have the car repaired. I am very concerned now about the long term viability and reliability of this car.

I am writing to formally lodge a complaint regarding the recent theft of my 2019 Hyundai Tucson, which I believe was exacerbated by a software update provided by Hyundai. Several months ago, I had my vehicle updated with a software patch at a Hyundai dealership, specifically intended to address vulnerabilities related to vehicle theft. However, despite the update, my vehicle was stolen on August 8, 2024, and later totaled in a crash. I have been informed by police and insurance company officials that thieves are now exploiting a method involving breaking a window and popping the ignition, as demonstrated in online videos. This method remains effective despite the software update. Adding to my frustration, Hyundai placed a sticker on my driver’s window to indicate the software update. This inadvertently advertised to thieves that my vehicle was among those with the known vulnerability, potentially making it a target.

Lost power when accelerating up highway hills, it coded P0420, catalytic converter on Bank 1 is not operating as efficiently as it should. This code is often caused by issues with the fuel or exhaust systems, which can result in insufficient oxygen leaving the catalytic converter. Hyundai dealer changed the catalytic converter July 2023, 1 yr to the day my vehicle did the same thing and had another Hyundai dealer change the catalytic converter to which 1 week later my car is still showing the code and is still jolting as I try to pick up speed.

The components that failed are the engine and transmission and parts associated with the functionality of these parts. It is currently in the shop but will be available for inspection upon request once repairs are complete. My safety and others were put at risk when these malfunctions occurred (driving incredibly slow on the highway could cause an accident, accelerator malfunctioning that might break, broken down late at night hours from home, parts catching fire from leaking oil, etc.). The problems have been acknowledged by my warranty company and the two repair shops that have serviced it. My car was inspected by Geico Insurance Company after I got rear-ended and needed to file a claim, however, the inspection was not specifically on my engine/transmission. The warning dash lights didn’t seem to come on until it was too late, especially during the transmission issue. I was driving around for days leading up to this issue thinking it was acting weird because it was due for an oil change but when I got one and nothing improved, I knew something was wrong. The check engine light did not come on until the car started to actively shut down and not move when I pressed the gas. The full detailed complaint is attached and receipts for repairs are available upon request. Attached is an overview of parts and pricing from the warranty company for the two claims.

Intermittent starting problem. Sometimes it won't start at all after as many as 12 attempts. Sometimes, it starts after several attempts. The weather does not seem to affect the problem. The EPB light has come on an stayed on after a non-starting episode but it goes off again too. It is not safe to drive because I get stranded. After it gets towed, it ends up starting at the mechanic's shop. No one, including and especially Hyundai will try to isolate and diagnose the issue. The issue is mentioned often on Hyundai owner's posts on internet forums but definite solutions are not mentioned.
