NHTSA Complaint #11661029 — 2017 HYUNDAI TUCSON

1)Component that failed: Engine 2)Driving 75 miles on the interstate in traffic and suddenly losing speed was very dangerous. 3)Yes, the issue is still occurring, even worse now as my vehicle shakes just starting the engine. 4) The mechanic has inspected, diagnosed and attempted to repair. However due to the condition of the engine, and the cost of replacing it; fixing may not be an option. 5)The engine light began flashing and then went off; then back to steady on. I purchased this 2017 Hyundai Tucson used just 4 years ago. Everything seemed to be working just fine, I've had regular oil changes. On Saturday, May 10, 2025, as I was driving on the Interstate with my cruise control set, I began to lose power and my speed slowed. I took my car off of cruise control and pushed on the gas pedal to gain speed and my car started to shake and it struggled to pick up speed. My mechanic has changed the spark plugs and performed a BG upper engine induction cleaning; did compression testing and leak down testing. He found that cylinder 4 has no compression. In addition to that, he noticed there was oil on the spark plug. I had my oil changed 3 months ago, and less than 3,000 miles - my engine is burning up the oil to the point where the oil level is extremely low. I have now found out that this is a known issue with this type of vehicle. I'm told it's $10,000 to replace the engine. I have no warranty coverage since I'm not the original owner. I was not aware of the class action lawsuit that was settled last year. I'm extremely upset that Hyundai has not recalled ALL the engines for this make and model of vehicle as it seems EVERYONE has had engine problems.
