ENGINE

Potential Consequences:

I first reported issues with my vehicle to a local Hyundai dealer January 16, 2023. I was advised I couldn’t get an appointment until March 8, 2023. Since March 8, 2023 I have taken my car to the dealer my numerous times for a series of testing over the course of 3 months. I was advised my car was burning too much oil of oil per 1000 miles. I was also advised that the transvalve and engine needed to be inspected by an adjuster to determine a faulty engine in order to get approval from the manufacturer. My car was at the dealer for almost a week. On June 15, 2023 the Hyundai dealership advised the engine was faulty. I was also advised warranty approved for a new engine due to faulty engine/oil consumption. I was advised to pick up my vehicle from the dealership. On June 16, 2023 I picked up my vehicle. I was told by the dealership to keep driving my vehicle until the new engine came in due. I was denied a loaner/rental at the time even though they knew the car had a faulty engine. Immediately after leaving the dealership dealership my car started smoking. I pulled over immediately got out. The car caught on fire and burst into flames. This was a very dangerous safety risk. It caused panic attacks, anxiety, headaches, and lots of sleepless nights. If I hadn’t gotten out sooner I could’ve been severely injured or dead. The car is with the insurance company. A field investigation has been done by the insurance. They determined faulty engine and total loss if the vehicle. It is still available for inspection if needed. There were no warning lamps or messages before the car started smoking or caught fire.

Potential Consequences:

When driving the car on the highway - "check engine - hybrid system" warning lights come on and indicate hybrid system issue and to shut car off immediately. Extreme safety issue as the car goes from highway speeds to 35MPH almost instantly. This has happened seven times now and Hyundai keeps indicating that technicians are following engineering guidance in fixing the issue related to the knock sensor. The seventh occurrence happened on May 23rd of 2023. First one was in December 2021. As Hyundai is unable to correctly fix the issue I have repeatedly asked for them to replace the car since it is an extreme safety issue but they will not do so. Still waiting for diagnosis of the latest occurrence from May 23rd. Hyundai does not acknowledge that this issue is of safety concern and just indicates that the issue has been fixed each time it occurs.
