Compare Infiniti Q50 loss of power repair quotes from specialist garages

The Q50 - a mid-sized premium executive saloon introduced in 2014 - is a standout model in Infiniti's lineup. It offers luxury, technology and style, resulting in a model that is easy on the eyes and capable of competing with class-leading rivals like the BMW 3 Series and Audi A4. Top speeds range between 120 and 155 mph.

In the US, where Infiniti is much more prominent, the Q50 is multi-award-winning. In 2021, for instance, it received the AutoPacific 'Vehicle Satisfaction Award' in the Standard Luxury Car category. There is a known problem with the brake pedal feeling spongy in some Q50s; this issue can be resolved by replacing the master cylinder.

Few things are as frustrating for a driver as realising your car doesn't have as much power as it should. Small changes in performance matter and are most noticeable during acceleration. Your car may suddenly lose and then regain power or feel sluggish all the time; either way, it's clear there's something wrong.

A loss of power can often be traced back to a problem in the fuel system, such as a clogged fuel filter, faulty injectors or a malfunctioning MAF sensor. Running a cleaning additive through the system every so often can help prevent issues like these from developing. However, the fuel system isn't always to blame.

As discussed in this guide, an ECU error or a clogged catalytic converter can also make your car lose power - that's why you should take note of any other symptoms that could help pinpoint the cause. These may include unusual exhaust smoke (blue, white or black) and rough idling.
