The car could have caught fire or stalled on the highway which is the safety issue. The vehicle was inspected by Tires Plus and got the P1327 code and also the Wallace Hyundai dealer in Ft. Pierce, FL which got same code.

The check engine light came on at 101000 miles. I took it to the shop and the mechanic said there was no oil on the dipstick and he put in oil and said we need a new engine because it is knocking. We have noticed the vehicle has a rough idle now.

I no longer have this vehicle, as I traded it in once I was able to lower some of my negative equity. During owning the 2020 Hyundai Elantra, a deer it the side of my vehicle and knocked me into the center of the road while I was driving. No airbags had come out, nor was any sensor activated. About 6-8 months later, I was driving down the same road and a deer had run across the road. The forward collision sensor did not alert me (I was paying attention to the road, but would have absolutely heard it), and my airbags did not deploy. My car suffered over $9,000 in damage and I had a concussion.

On January 1, 2025, I discovered my vehicle had been stolen after finding broken glass in my driveway and immediately reported the incident to the police, who arrived within approximately 20 minutes; neighbors later provided camera footage of the theft, and I also observed other nearby vehicles with similar damage, including a broken rear window and another Hyundai Elantra that appeared abandoned. The following day, police informed me the vehicle had been recovered, and upon inspection I found the rear driver-side window completely broken and the ignition area under the steering wheel damaged. Couple months later I received a recall notice for the antitheft system on my 2020 Hyundai Elantra (VIN [XXX] ). When I brought the vehicle to the dealership on April 1, 2026, I was informed that the recall cannot be completed unless an additional part is replaced, at a cost of approximately $1,178. This part was damaged during a prior theft incident. My vehicle was stolen last year and later recovered, and it sustained damage during that incident. However, I understand that safety recalls are required to be repaired at no cost to the owner under federal law. I am concerned that I am being asked to pay for repairs in order to complete a safety recall, and that my vehicle remains vulnerable without the recall remedy being performed. I am also concerned about the safety and legal compliance of continuing to operate the vehicle under these conditions. I am attaching supporting documents as proof of the vehicle theft, along with the reports provided by the dealer.
