2017 Infiniti QX70: Common Problems and Issues to Know

The 2017 Infiniti QX70, a luxury crossover SUV, has drawn attention for its sleek design and robust features. However, like any vehicle, it has its share of issues that potential buyers or current owners should understand. Being aware of these concerns can help make informed decisions about ownership and maintenance.

Engine Performance Issues

The 2017 Infiniti QX70 is known for its luxurious appeal, but some owners have reported concerns with engine performance. A common issue is a lack of responsiveness during acceleration, particularly noticeable when merging onto highways or overtaking. This can diminish the driving experience expected from a vehicle in this class.

Another reported issue is occasional rough idling, which may present as vibrations or uneven engine sounds when the vehicle is stationary. While it doesn’t immediately affect drivability, it could indicate problems such as spark plug wear or fuel injector issues. Regular maintenance can help identify and address these concerns early.

Fuel efficiency has also been a point of dissatisfaction for some owners. The engine’s power may come at the cost of higher fuel consumption, especially in urban settings. Keeping the vehicle well-maintained with clean air filters and properly inflated tires can help improve fuel economy.

Transmission Concerns

The transmission system of the 2017 Infiniti QX70 has drawn mixed reviews from owners. A common complaint involves delayed shifting, which can disrupt the smooth driving experience and cause hesitation during gear changes, particularly in stop-and-go traffic or when accelerating from a stop.

Some drivers have also reported unusual noises from the transmission, such as whining or humming. These sounds may indicate issues with transmission fluid or the gearbox. Regular checks of transmission fluid levels and quality can help maintain smooth operation.

In rarer cases, transmission slipping has been reported, where the vehicle unexpectedly changes gears or struggles to maintain a gear. This can lead to a temporary loss of power, creating potential safety concerns. Addressing these symptoms promptly with a mechanic can prevent more significant damage.

Electrical System Faults

The 2017 Infiniti QX70 features a range of advanced technology, but owners have encountered issues with the electrical system. The infotainment system, for example, has been described by some as unresponsive or slow to start. These delays can hinder the use of navigation or audio controls. Keeping the system’s software up to date may help resolve such problems.

Some drivers have also experienced dashboard indicators and warning lights flickering or illuminating without cause. These issues may stem from faulty sensors or wiring problems, which require diagnostic tools to address. Regular inspections of the vehicle’s electrical connections can help prevent such disruptions.

Battery performance has been another concern, with some owners reporting premature battery drain. This issue may be caused by parasitic draws from electronic components that remain active even when the vehicle is off. Identifying and addressing unusual power draws can help extend battery life.

Suspension and Handling

The 2017 Infiniti QX70’s suspension and handling have elicited mixed feedback. The suspension system, designed for a sportier feel, can feel stiff over uneven surfaces, which may not appeal to drivers seeking a more cushioned ride.

Steering response has also been mentioned as a concern, with some owners finding it less precise than expected. This can affect driver confidence, especially during spirited driving. Ensuring proper tire condition and alignment can improve steering feedback and handling.

Interior and Comfort

Inside the 2017 Infiniti QX70, the cabin blends luxury with practicality, but some owners have noted issues that affect overall comfort. Over time, squeaks and rattles may develop in areas like door panels or the dashboard, which can detract from the serene environment.

The seating has received mixed reviews. While the leather seats are plush, their contouring may not suit all body types, leading to discomfort on longer trips. Additionally, the rear seating area can feel cramped for taller passengers due to limited legroom, which could be a concern for families or those frequently traveling with multiple passengers.

The infotainment system, though praised for its intuitive layout, can occasionally be hindered by responsiveness issues. However, features like the premium sound system and climate control generally enhance the overall comfort for occupants.

Exterior and Bodywork Flaws

The 2017 Infiniti QX70’s exterior design is striking, but some owners have reported concerns with paint quality. Premature fading or chipping can occur, especially in areas exposed to debris or harsh weather. Regular waxing and protective coatings can help preserve the vehicle’s appearance.

The bodywork’s design, with its curves and angles, has also been noted as more prone to minor dings and dents from road debris or parking lot mishaps. Maintaining the vehicle’s pristine look may require more frequent touch-ups or detailing.
