2017 Hyundai Sonata — Known Issues & Recalls

Your engine started knocking, then stalling, and eventually stopped running completely. You found a recall on the Hyundai website that matched your symptoms, but the dealership claimed your vehicle isn't covered under that recall and is charging you $4,926.53 for repairs. The service department blamed inadequate oil changes rather than acknowledging the potential recall issue. The repair will likely involve engine diagnostics and potentially engine component replacement or rebuild.

Your engine suddenly failed while being driven, after making a knocking sound beforehand. No warning lights appeared before the failure. The dealer confirmed this is a known issue with your vehicle but refused to repair it because your service records were incomplete. The manufacturer was notified, and this happened at around 95,000 miles.

My 2017 Hyundai Sonata Hybrid has a permanent and recurring DTC P1326 (Knock signal range/performance) from the Knock Sensor Detection System (KSDS), indicating potential connecting rod bearing wear in the Nu 2.0L engine.

My 2017 Hyundai Sonata is exhibiting a severe metallic knocking noise and metal debris in the engine oil—primary indicators of the Theta II engine defect (NHTSA Campaign 17V578). These symptoms indicate imminent engine failure, posing a significant stall and crash risk. On or around 8/20/25, I took the vehicle to Earnhardt Hyundai-San Tan.

The 2017 Hyundai Sonata has had an ongoing engine malfunction defect that is causing engine knocking, stalling, and smell and rapid depletion of oil. The continuous issues are concerning especially when the car is not driven on a regular basis as it is utilized as a second vehicle. This has been a noticeable issue for quite sometime now.

The contact owns a 2017 Hyundai Sonata. The contact stated that the vehicle had experienced excessive oil consumption, caused by engine rod bearing failure. The engine rod bearing failure caused excessive oil consumption and premature spark plug fouling, requiring the frequent replacement of the spark plugs.

I have a 2017 hyundai sonata sport,it started using a lot of oil,one day I was driving and it just lost speed and the car just started jerking. I checked the spark plugs and oil had gotten on them. I changed the spark plugs,drove it for about 2 weeks and it did it again.

My car stayed with up to date oil changes and everything. One day I noticed it was leaking oil and had to stay on top of adding oil. When took to a mechanic they said my motor was blown and needed a new one.

Please see the attached paperwork and I have more if needed. I am not receiving any help from the local Hyundai dealership in which I purchased the car, and I have reached out to the main Headquarter. This is the 2nd Hyundai I purchased, and I was not made aware of the oil consumption issue.

Car just sputtered and then the engine stopped working in cyclinder 2

While driving around 45 MPH, the steering wheel locked up and car came to a hard stop. Luckily cars swerved to avoid me. This was the second time it happened.

Was just driving and lost steering, basically very hard to turn the wheel. Traction control light and a red steering wheel light came on.

Your driver's side seat belt isn't locking securely and loosens unexpectedly while you're driving, which means it won't protect you properly in a crash. You've reported this to both the dealer and manufacturer, but the vehicle hasn't been repaired yet. The seat belt retractor mechanism may need to be replaced or serviced to restore proper locking function.

My vehicle has a documented excessive oil‑consumption defect. After a 1,000‑mile oil‑consumption test performed by a Hyundai dealership, the engine was found to have consumed 2.8 quarts of oil, which is far above normal and poses a safety risk. The dealer referenced TSB 23‑EM‑008H and recommended a chamber cleaning but could not guarantee it would resolve the issue.

I was involved in a severe motor vehicle collision in a 2017 Hyundai Sonata. The airbags failed to deploy during the crash. I sustained serious injuries and was transported from the scene by EMS.

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.

This car is becoming more of a headache than it’s worth. Turned the car on, My car started shaking and my check engine light came on. then I got this message “A possible condition with your engine control system has been detected on a 2017 Hyundai Sonata”
