Reliability is a key factor every consumer considers when buying a car. However, even reputable manufacturers like Hyundai, General Motors, Audi, Ford, and Subaru have had their fair share of engine issues.

In this article, we’ll delve into the engines to avoid from these manufacturers. Learn more here!


  1. Hyundai/Kia: 2.0-L & 2.4-L Four-Cylinder
  2. Hyundai and its sister company, Kia, have faced significant challenges with their 2.0-L and 2.4-L four-cylinder engines. These engines have been known to spontaneously seize, leading to potential engine failure.

    The problem arises from metallic debris left behind during the manufacturing process, which restricts oil flow to connecting rod bearings, causing them to wear and fail. This issue has resulted in a recall of 1.4 million cars and SUVs and has affected various models, including the Hyundai Santa Fe Sport, Sonata, and the Kia Optima and Sportage.


  3. General Motors: 2.4-L Four-Cylinder
  4. Another engine to avoid is the 2.4-L four-cylinder engine used in particular General Motors vehicles, such as the Chevrolet Equinox and GMC Terrain. Owners of these vehicles have reported significant issues with the engine, including excessive oil consumption and timing chain failure.

    Excessive oil consumption can lead to engine damage and even complete engine failure if not addressed promptly. Some owners have reported consuming as much as a liter of oil for every 1,600 kilometers traveled.


  5. Audi/Volkswagen: 2.0T Turbo Four Cylinder
  6. Audi and its parent company, Volkswagen, have faced legal challenges due to defects in their 2.0T-powered models. These turbocharged engines have been found to consume oil at alarming rates, leading to potential engine damage.

    Approximately 126,000 Audis with turbocharged engines have been affected by this issue, with models such as the Audi A4, A5, and Q5 being particularly problematic. The defects in these engines can cause rapid oil consumption, resulting in failure if not addressed promptly.


  7. Ford: 1.6-L EcoBoost Four Cylinder
  8. The 1.6-L EcoBoost turbo direct injection engine used in certain Ford vehicles has been plagued by overheating and coolant leakage issues. Owners of Ford Escapes, Fusions, Fiesta STs, and Transit Connect vehicles have reported coolant leaks and coolant mixing with engine oil. This can lead to engine overheating and, in some cases, engine fires.

    Ford has issued recalls for these vehicles to address the coolant leakage issue, but the problem persists for some owners.


  9. Subaru: 2.5-L turbo Four Cylinder
  10. Subaru’s 2.5-L turbocharged engines, particularly those used in the Subaru Impreza WRX and WRX STI models, have been the subject of a class-action lawsuit.

    The engines have been found to overheat or malfunction, leading to power loss, stalling, and potential engine failure. Drivers have reported sudden loss of power and engine stalls due to overheating and seizure of internal engine parts. This issue has raised concerns about the reliability and safety of these vehicles.  


Top Signs of Engine Failure

Engine failure can be an expensive and frustrating experience for any car owner. Awareness of the warning signs can help you take prompt action and prevent further damage. Here are some common symptoms of engine trouble you should watch out for:

  • Unusual noises – Knocking, ticking, or grinding noises from the engine can indicate internal problems 
  • Excessive smoke – Blue smoke from the exhaust means burning oil, while white smoke may indicate coolant leakage. 
  • Poor performance – Reduced power, sluggish acceleration, and decreased fuel efficiency can be signs of engine trouble. 
  • Overheating – If your engine consistently runs hot or frequently overheats, it may be a sign of underlying issues. 
  • Warning lights – Illuminated check engines or oil pressure warning lights should never be ignored. 
  • Vibrations – Excessive engine vibrations or shaking can indicate imbalances or mechanical issues. 
  • Hard starts – Difficulty starting the engine, especially when combined with other symptoms, may signal a problem. 
  • Increased exhaust emissions – Dark or unusual exhaust emissions can indicate engine difficulty. 
  • Loss of power – Sudden loss of power or stalling during operation may point to engine issues.
