3 Signs Your Car's Turbo Has Blown

November 5, 2025

If your car isn't performing as it used to, there might be an underlying issue that you haven't yet addressed. Turbochargers enhance engine efficiency and power, but when they fail, they can cause significant problems with vehicle performance and may require a visit to the mechanic shop. Timely detection and repair of a blown turbo can save you from costly repairs down the road. Today, we will explore the signs that indicate your turbocharger might be blown and what you can do about it.


1. Reduced Power 

One of the most telling signs of a blown turbo is reduced engine power. If you notice a significant drop in your car's acceleration ability, the turbo might be struggling to deliver the expected boost of power. This loss of power is often due to the turbo's inability to generate expected levels of compressed air. A well-functioning turbocharger is crucial for ensuring your engine can perform optimally; when it’s impaired, the entire system can suffer.


2. Strange Noises 

Unusual noises coming from the engine area are another sign that your turbo could be compromised. Often described as a loud whining or whistling sound, these noises occur when the turbo’s internal components have become damaged. The problem at hand is linked to durability, a concern that accounts for 80% of car repairs, according to Brandon Gaille. Components like the turbo are subject to wear and tear, and the issue generally escalates without timely intervention from a mechanic shop.


3. Exhaust Smoke 

Another telltale symptom of a failing turbo is excessive exhaust smoke. When the turbo becomes faulty, it can result in oil leaks which, in turn, lead to a noticeable increase in exhaust smoke. This smoke is often bluish-grey, indicating that oil is burning off somewhere within the system. If you observe this happening, it’s imperative to consult a professional mechanic promptly before further engine damage ensues.


Maintaining your turbocharger is essential to ensure your car operates at its best. By staying alert to signs like reduced engine power, unusual noises, and excessive exhaust smoke, you can address issues before they become costly repairs. Remember, timely action not only extends the life of your turbo but also contributes to the overall health of your vehicle.
