2021 INFINITI QX50 Complaints

The contact owns a 2021 Infiniti QX50. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the engine compartment, prompting the contact to discontinue driving the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the engine bearings, resulting in damages to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling). The VIN was included, but the vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was later informed that the manufacturer would not cover the cost to replace the engine because the failure failed to meet the requirements for engine replacement. The failure mileage was 80,000.

Without any warning or indicator light on the dash, the vehicle lost power when pulling out of our driveway - we live on a main road and were very lucky not to be hit by upcoming traffic. The car went into limp mode and would not accelerate past 20mph. We have been fighting with Infiniti for the last three weeks as no one can find the problem and they finally said a new engine was needed. There is on 35,000 miles on this car and we had to fight to have this replacement covered under warranty. Now that parts are back ordered and we are not receiving any help. We are three weeks without a vehicle and have no loaner vehicle. No one at Infiniti can give a timeframe for the resolution of this issue, what caused this issue and we are now very fearful that this will happen again - even with an engine replacement. This was very scary for our family and we are amazed that there was no indicator light or warning. The car didn't make any noises and was running great and then all of a sudden it would not go. Very alarming to say the least!

I purchased this 2021 QX50 Infiniti on [XXX] and have experienced consistent engine knocking. In checking out this problem, I have found that it is apparently a widespread problem with the engine in 2021 QX50 vehicles and can possibly lead to engine lock up and engine failure. The engine thus far has not locked up or failed. I have reported the issue to the dealership, Infiniti of Gwinnett located at 3090 Satellite Blvd, Duluth, GA 30096 and am scheduling to have the dealership investigate the problem. Needless to say this is a major concern and if there are ongoing NHTSA investigations and findings I definitely want to be made aware of same.

The contact owned a 2021 Infiniti QX50. The contact stated that while driving at 25 MPH, he collided with another vehicle on the rear driver's side of the vehicle. As a result, the vehicle was thrust off the roadway, coming to a complete stop after colliding with a pole, and the front passenger side wheel disconnected from the axle. The air bags were deployed. A police report was filed, and injuries were reported. The contact was later treated for various nondescript injuries. The vehicle was towed to a tow yard and declared a total loss by his insurance. The manufacturer was not notified of the failure. The failure mileage was unknown.

While driving on a clear day with no traffic in front of me or debris on the road at approximately 45 mph, a master warning light appeared on my dash with an accompanying warning signal and simultaneously the emergency braking system engaged and brought my vehicle to a sudden stop. As quickly as it started, the warning and braking ceased and left me stunned and terrified. Had I been in traffic or on a highway, I am quite certain that I would have been rear-ended. Luckily, that was not my fate yesterday but this defect is serious and dangerous. I have contacted the dealer and dealer service department. The service department informed me that they could inspect the vehicle in 4 weeks. The dealer said that there are multiple computers in the vehicle and that computers can be glichy. This vehicle has had multiple computer issues since I first leased the car starting approximately 5 months into my lease. I have received a malfunction warning on numerous occasions and have had it in for service where they told me that they inspected the vehicle and all systems seemed to be working fine even though I showed them multiple pictures of the warning. The dealer told me that I should disregard the warning and that customers complain about it often but that it just indicates that there is snow, ice or debris covering the sensors. This is not consistent with my experience.

This vehicle is equipped with a push button to start and stop the vehicle engine. The button is mounted horizontally next to the gear selector switch near the driver. Twice now, while traveling at highway speeds, the vehicle engine has stopped when my dog taps on the switch. I usually secure my dog while traveling with him, but there are occasions when his seat belt needs to be released, usually due to him getting tangled up. If you own a dog than you know that he will tend to want to climb on top of you as soon as he is released from his leash, so putting the button in that position represents a pretty significant safety issue for me. I have called and reported this to Infiniti, and the agent told me I needed to fashion some sort of cover for the button, and ask my dealer if there is a software solution.

Picked up the car on 5/25, on 6/4 sitting at a red light, forward collision warning and lane assist malfunctions showed up on dashboard. Called Faulkner willow grove where my company leased the car, the set up an appt on 6/17. the next day, 6/18 both malfunctions came back, I called and said I don't have time out of my day to drive back and forth for you to not fix my car, he told me to go somewhere else and found Holman Infiniti, they scheduled me on 6/25, they found I needed a new camera but the part was on a national backorder no eta. on 7/6 my car auto breaked with nothing in the way on a clear sunny day, called Holman they told me this happens all the time just accelerate, the engineers know its a problem, there's not current fix and you can't turn it off and he told me to call customer assurance to open a claim which I did, on 7/7 customer assurance called me back assigned me a case manager, on 7/8 Holman told me my camera part was in stock, scheduled an appt on 7/15, on 7/18 the forward collision sensor blinked the entire drive home.

there was a problem with safety recall a week after I took the vehicle test! I went to the dealer in Las Vegas many times, but they didn't find the mistake, they told me that the car was in order! There are no warning lights on the dashboard! Everything seems fine, but I don't know why he still writes it safety recall, don't clear this and why no one can clear this and help me!
