The 2021 Infiniti Q50 has generated 2 NHTSA complaints for this defect category. If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “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” (NHTSA Complaint #11563968)
Advanced driver assistance system (ADAS) defects — including malfunctioning forward collision warnings, lane keep assist failures, and erratic automatic emergency braking — can create dangerous driving conditions. The 2021 Infiniti Q50 has 2 NHTSA complaints for this defect type. Owner reports include: “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.” (NHTSA Complaint #11460324)

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2021 Infiniti Q50:
Once the presumption is triggered, the burden shifts to Infiniti to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Infiniti must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2021 Infiniti Q50 qualifies as a lemon under California law, Infiniti may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Infiniti a reasonable opportunity to fix the defect. Visit different authorized Infiniti dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Infiniti pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Infiniti a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Infiniti is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
