What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2021 INFINITI Q50, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
I was driving home on the Veterans Expressway in Tampa traveling about 65 mph when a sound like a gunshot almost caused me to lose control as I swerved out of fear - thankfully no other vehicles were nearby. I pulled over at the next exit in a public place and discovered my sunroof class had a piece of glass missing and it looked like it was pushed upwards. I knew this is not normal and never had I had this happen in any other car I owned with a sunroof. I had very small slivers of glass inside the car which cut my fingers because they were not visible, along with the tempered glass. Since it was going to rain, I drove home and put in garage to avoid water damage. I called the dealership in Sarasota and they stated this was reported by another customer in recent months. There was no warning there was a problem with my sunroof, nothing hit it, and it had been opening and closing with no problems. I’m lucky not to have crashed. In addition, flying glass that broke free created an even more dangerous situation for other drivers - thankfully the road was empty - by the time I was able to get to a gas station closer to home, the majority of the glass was missing. I researched the problem online and discovered numerous reports online suggesting this is a frequent problem with Nissan/Infiniti - apparently there is already a class action suit, but not for my model. Please investigate this dangerous problem immediately and ask Infiniti to inspect and issue recalls on their sunroofs. Unfortunately I believe they know a problem exists and have not issued a recall for the safety of their consumers. The cost to repair is in the thousands and I am without a car plus there are glass shards inside my car. **I tried to upload pictures but wasn’t able to do it from my phone - I have multiple pictures to share

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
I purchased a new 2021 Infiniti Q50 from Infiniti of Cool Springs on September 28, 2020. There was an incident on January 13, 2022 due to a manufacturer defect that caused my car to accelerate on it’s own. I was parked at a car wash to vacuum my vehicle. I had my foot on the brake to move the gear shift into park when my car rapidly accelerated which caused me to crash through a metal fence that separated the car wash from the adjacent property. I have an added safety feature on my vehicle to prevent a forward collision with emergency breaking that also didn’t implement. There wasn’t any warnings, indications or symptoms beforehand. I had my Infiniti for 16 months with only 20,766 miles on it at the time of the incident. This malfunction could present a serious public safety issue. I or someone else could have been seriously injured in a different scenario. It was fortunate that I was stopped and no one was in front of the car. Nissan issued a recall on April 3, 2021 for the problem of rapid acceleration. The dealership without my knowledge completed the recall on my vehicle on April 1, 2021 which evidently didn’t fix the problem. Nissan and the dealership have been and are therefore aware of the problem. Infiniti Consumer Affairs nor the dealership want to assume any responsibility for the malfunction. An inspection has not been performed yet. Infiniti Consumer Affairs requires me to assume responsibility for the cost of a rental during the 6 - 8 week inspection of my vehicle along with the cost of any storage fees. The vehicle can be inspected at Infiniti of Cool Springs. It’s been there since the incident.

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
The contact owns a 2021 Infinity Q50. The contact stated that the vehicle was recently purchased from a dealer. When the vehicle was purchased, the tires were replaced. The vehicle was later taken to the dealer for maintenance, and while at the dealer, the contact was informed that there were nails in the tires and that the tires needed to be replaced. The contact checked the sticker on the door panel for the tire information. The contact stated that the sticker indicated that the wheels were 18-inch rims. The vehicle was taken to the dealer to install the new tires, and the contact was informed that the rims on the vehicle were 17-inch rims. The vehicle was purchased at a CarMax dealer, and the contact asked why the 17-inch rims on the vehicle. The contact was informed that the ride would be better with the 17-inch rims and tires. The rims were not replaced. The manufacturer was not notified of the issue. The failure mileage was approximately 44,000.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
