Updated on August 7, 2024

In the midsize sedan market, INFINITI has got sufficient popularity for manufacturing some of the best vehicles so far. The Q50 Pure, with a market price of $42,100 definitely comes under those sedans best known for their extraordinary performance and reliability factor. While it comes to reliability, the Q50 has some of the finest competitors like the Genesis G70 2.0T 4dr sedan that sells for $36,150, the Kia Stinger GT Line 4Dr sedan with a price tag of $36,290, and the Alfa Romeo Giulia with a starting market price of $42,950. Despite facing such challenges, the Q50 stands with a score of hitting a sales volume of 13,894 units in the respective year, with Stinger coming close by hitting a sales volume of 13,517 units.

However, the popularity of the Q50 is questioned by the NHTSA report that records 3 recalls and 1 complaint for the specific year. Users have raised issues about the vehicle’s faulty speed control causing the vehicle to accelerate even when it's in parking mode. Such issues compelled the manufacturers to replace and repair the faulty parts with a new ones for free of cost.

Safety Problems

Faulty speed control

Speed control issues are a major concern in most of the Infiniti Q50s. Users have found the vehicle starts accelerating on its own while resting the foot on the brake pedal to change the gear shift, triggering a crash by hitting the objects stalled in the front.

Engine and Mechanical Problems

Emergency brakes stop working

The emergency braking system in a vehicle stops working to prevent frontal crashes whenever required. Users have found the emergency brakes unresponsive while engaging them to prevent unwanted crashes. Instances like these may trigger unwanted accidents when there are passengers inside the vehicle.

The worst part is when the emergency brakes fail to deploy the car barely shows any warning sign or indication, as the driver realizes only after ramming up to something, leading to damage to the car body or causing injury if it bumps any human( if there’s any). Such instances should be taken into consideration and needed to be rectified soon.
