When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2021 Infiniti QX80
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202634411,868 units in Canada
Label
Issue: On certain vehicles, the compliance label may list the wrong gross axle weight rating (GAWR) information. This could lead you to overload the vehicle and cause poor handling or a tire failure. Note: This recall only affects models equipped with 22-inch wheels. Safety Risk: Poor handling or a tire failure could cause a loss of vehicle control and result in a crash. Corrective Action: The company will notify owners by mail and provide you with a new compliance label. If you'd like help to install it, you can contact a dealer to have it installed free of charge.
Recall 2021483247 units in Canada
Visual System
Issue: On certain vehicles, a software problem could cause the navigation screen/multifunction control touch screen not to work when the vehicle is started. If this happens, the rearview camera image will not appear on the display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear. Note: This can happen if the "privacy mode" feature is activated and the vehicle is not started in the following 14 days. Safety Risk: A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Action: Infiniti will notify owners by mail and instruct you to take your vehicle to a dealer to update the telematics control unit (TCU).
Recall 2021314726 units in Canada
Fuel System
Issue: On certain vehicles, the fuel pump could fail. If this happens, the engine could stall while driving. Safety Risk: A sudden loss of engine power could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct you to take your vehicle to a dealer to replace the fuel pump module.

VEHICLE SPEED CONTROL
I have been saying that my vehicle is a safety hazard since April 2022. I have had it to the dealer 4x since then in addition to opening up several cases with Inifiniti Customer Service, but nobody has been able to protect my family and I and remedy the situation. At times the vehicle will not accelerate even when I push the gas all the way down. Then it will kick in and surge forward. I also have told them that at times it feels as if someone has rear ended me. There is a recall out there for cars manufactured through April 2020, but mine was manufactured in September 2020. Infiniti's recall is #R21A3 and the NHTSA ID is 21V373. I have experienced the same exact symptoms as those covered under this recall. Now Inifiniti is telling me that my transmission needs to be replaced as a result of metal shavings in the oil. Again, this could all have been caused by this fuel pump issue which was on their radar in 2021 and 2022 when I brought my car in the first time. Infiniti has failed to help me in every step of the way beginning with their Service Tech not fixing the issue back in 2022 through 2024 when I have consistently expressed my concerns while the car was still under warranty.

POWER TRAIN
This is a 2021 Vehicle, and beginning in April of 2022, I have been telling my dealer that there is something wrong, but they haven't been able to fix it. When I am driving, there are times when the car will fail to accelerate. Also at times it feels like I have been rear ended and the car lurches. I have said this is a safety issue and neither the dealer nor Inifiniti Customer Consumer Affairs have taken this seriously and remedied the situation. They all say there is nothing they can do. I have taken it to the dealer 6 times and opened up a case with Infiniti back in 2024 with no resolution.
