Infiniti Q50 Years To Avoid: Problems In The Worst Years of Infiniti Q50 Sedans
The following section covers the points in the table and their solutions.
The first year of the Infiniti Q50 had several problems and had the most recalls. These problems included
1. Steering Problems
One of the notable features of the Infiniti Q50 was the Direct Adaptive Steering System (DAS.) However, it went on to be among the problems the car experienced that year.
The system can develop problems during startup, affecting the vehicle’s responsiveness and the turning radius. Thus, the power steering software is also known to disable the electric steering system when the temperature drops too low.
Consequently, there were two recalls regarding the steering problems. The dealership reprogrammed the ECU software controlling the steering, which solved the issues.
2. Air Bag Deployment Problems
The airbag deployment problem plagued the first three years of the Infiniti Q50. In case of an accident, the airbag on the front seat passenger would not deploy as expected.
Likewise, the Occupant Classification System (OCS) would fail to identify a person seated on the passenger and deactivate the airbags. In another scenario, the system would detect an adult as a child.
The solutions include reprogramming the OCS and the Airbag Control Unit (ACU.) Also, sometimes the Electronic Control Unit must be replaced to fix the problem. All these solutions were provided free of charge in April 2016 during recall number 16V244000.
3. Transmission Housing Problems
The transmission housing problem was common on the hybrid Infiniti Q50s of the year 2014. It involved cracks in the transmission assembly, disabling the vehicle.
These problems were caused by damaged housing during manufacturing that might have gone unnoticed. The manufacturer, Nissan, noticed the problem sooner and issued a recall number 14V582000. They inspected and replaced any transmission housing with cracks for free.
4. Sensor Problems
This problem was also on the Hybrid Infiniti Q50 year 2014 and involved throttle position sensors. A software error would cause any of the two sensors to lose signal.
With the signal lost, the engine control module (ECM) would go to fail-safe mode closing the throttle chamber partially. After regaining the signal, the throttle chamber would open, causing the car to gradually accelerate.
The solutions include reprogramming the ECM, which can cost between $150 and $300. However, Nissan recalled vehicles with these problems, including Infiniti Q50, and fixed the problem free of charge.
By 2015, some of the problems with the previous year of the Infiniti Q50 had been resolved. However, some new and previous issues plagued this model year. They included
1. Premature Tire Wear
The 2015 Infiniti Q50 standard tires wore out quickly, costing expensive replacements. The problem would occur as early as 10,000 miles with the common problem being splitting at the rim.
Solutions involve replacing the tires, which can cost anywhere between $350 and $650. To avoid frequent replacement, drivers should replace with other tire types which are more durable
2. Brake Issues
The brakes in the Infiniti Q50 are known to have several issues and also wear out fast. They can wear as early as 5,000 miles, and if not replaced, they can allow damage to brake rotors and calipers.
Moreover, the master cylinder is also known to leak internally, affecting the responsiveness of the brakes. This problem is known to appear after 100,000 miles but sometimes sooner.
Solutions include replacing the brake pads, which can cost as high as $300 each time they wear out. Master Cylinder replacement costs between $400 and $1,000, including labor costs.
