More than 95,000 Hyundai Sonata Hybrid sedans and Tucson SUVs from the 2017 model year are being recalled because their engines may suddenly stall or even catch fire. This is part of an ongoing series of recalls by the automaker for similar problems.

Hyundai says that the connecting rod bearings, which allow rotation for the piston to move in and out of the cylinder, could prematurely wear out in these vehicles’ engines. This could result in a knocking sound from the engine, along with the illumination of an oil pressure warning light.

If the condition is not addressed, the engine could become damaged to the point where it will stall during operation, increasing the risk of a crash. In some cases the engine block could become damaged to the point of causing an oil leak onto hot engine surfaces, risking fire.

Drivers whose vehicles suffer from this condition may notice any one of these warning signs:

  • Abnormal (knocking) noise from the engine
  • Reduced engine power and/or hesitation
  • Illumination of the Check Engine warning light
  • Illumination of engine oil pressure warning light
  • A burning smell, oil leaking, and/or smoke

According to NHTSA documentation, Hyundai is aware of 45 fires that are related to this problem. There are no reports of crashes or injuries related to this recall.

Check to see whether your vehicle has an open recall: NHTSA’s website will tell you whether your vehicle has any open recalls that need to be addressed.

If you plug your car’s 17-digit vehicle identification number (VIN) into NHTSA’s website and a recall doesn’t appear, your vehicle doesn’t currently have any open recalls. Because automakers issue recalls often, and for many older vehicles, we recommend checking back regularly to see whether your vehicle has had a recall issued.
