The 25 vehicles with the most reports

Each row is one model year. The bar is its count of turbo problems reports; the share is how much of that car's complaint file this problem takes up. Bigger sellers draw more reports, so read the share alongside the count. Red dots mark crashes and fires in these reports; amber marks a recall on the same system.

What it is and what to do

A turbocharger is a compressor that forces extra air into the cylinders so more fuel can be burned. The government's fuel economy site explains that's what lets automakers use smaller engines without giving up performance.

It's a small group, about 1,650 complaints across the vehicles on this site, with a median mileage of about 62,000. The 2018 Honda Accord and the 2017 and 2018 Honda CR-V are at the top. About one owner in eight mentions a loss of power or hesitation, around one in eight mentions boost or a boost code, and one in eleven mentions smoke. Firestone ties blue or gray exhaust smoke to burning oil, and a malfunctioning turbocharger is one of the ways oil gets into the combustion chamber.

NHTSA's files show how a turbo problem can hide behind a service bulletin. Its 2013 investigation PE13-018 looked at 95 complaints of reduced power during hard acceleration on 2011 to 2013 F-150s with the twin-turbo 3.5L EcoBoost, after Ford had already issued three service bulletins about moisture collecting in the charge air cooler. On some Nissan VC-Turbo engines the trouble went deeper: investigation PE23-023 led to recall 25V-437 on some 2019 to 2024 Rogue, Altima and Infiniti models, where defective engine bearings could cause engine failure, and the remedy is new engine software.

Expect a scan for stored codes first, Firestone's standard step for a warning light, and ask whether any bulletin covers your engine. Tell the shop exactly when the power drops (full throttle, merging, climbing a grade, in humid or cold weather) and whether you saw smoke.

Losing power while merging or passing is the hazard. If the engine goes into a reduced-power mode, get off the highway and have it checked rather than driving on at low power. A flashing check engine light is Firestone's signal to stop driving.

Run the VIN on NHTSA's recall site and look at the manufacturer bulletins NHTSA posts, since a fix may already exist, as it did for the F-150s. If you're still under warranty, get the fault on a repair order; the FTC says a defect reported during the warranty period has to be fixed even if the warranty expires before the repair.
