I went to Evo Motors to find a car and found a car filled out an application and had to return to the next day because they were closing There was already talk about a down payment but no credit transaction was happening yet. I didn’t even have an offer on the credit yet so I came back the following day and on the way there I got a phone call that the bank was requesting a down payment in the amount of $4500. The salesperson was requesting cash downpayment and I thought that was strange since that was a lot of cash to have on hand. Me and girlfriend had a decent score to acquire the car but the dealer insisted on the cash downpayment and told us the bank was requested the down payment in order to get the car. I was very uncomfortable but I needed the car as I had lost my previous car in an accident and I needed to get to work and was in a rental car. I demand my down payment back in the amount of $4500 plus interest and keep the car as the transaction was unconscionable. They took advantage of my position in the basic necessities and livelihood as I needed to keep working to survive. The added burden was that I had to call friends and family all day long to come up with a downpayment I didn’t have and I had to pay everyone back in a short time. I was so stressed that I got sick and have still not recovered from the transaction that took place that has led to the moment where it was not fair to extort funds I did not have to further benefit them even after had already enriched themselves with the sale of a vehicle that had a very high-interest rate for our credit profile. It’s obvious they had complete control over every aspect of this contract.

The Air bag system on a 2018 Infiniti Q50 AWD is malfunctioning. I’d like to get it checked out especially if this could be a tentative recall issue for myself and other owners of the same vehicle. I feel very unsafe for my family and I because the system was never tampered with, yet the light used to go away randomly. Currently, the light is permanently on, and passenger airbag light states the system is off from deploying in case of an accident. This would mean that I would be driving at a risk of airbags being non-deployable and that is truly unsafe. This problem was not addressed with a dealer or any other service center. The vehicle has never been inspected yet, but it is a concern that I’d like to move forward on. The passenger airbag light is illuminated on my dashboard as well as the light depicting that the system is off. I recently bought this car July 2022 and within six months from purchase the light started coming on randomly and disappearing. Now it is permanently on.

My coolant reservoir kept on going empty, I took to dealer for service they replaced the radiator fan module and told me my engine was not porous. I was driving and my engine ended up stalling, turned off while I was driving in the freeway at a high speed cause me to almost lose control of my vehicle because everything stopped working. It looks like an inner rod failed possibly because of the coolant going into engine.

2/1/2023 we took our 2018 Q50 to the Infiniti dealership and service center. The engine was having issues, increased RPMs while simultaneously experiencing loss of power/stalling. This was experienced by both my wife and I. Infiniti's determination was the Mass Air Flow Sensor and told us the issue was not covered by the platinum, bumper to bumper extended warranty they sold us due to the warranty only covering mechanical issues, not electrical. The service tech was able to get costs waived as factory warranty covered such events to 75k miles. We picked the car up on 2/8/2023. On 3/18/2023 the car was again towed to the dealership. The intermittent issue that was thought to be the Mas Air Flow Sensor and electrical, hit suddenly and with such force the car would not run whatsoever and stalled out on a very busy 50 MPH Parkway and my wife had to maneuver her way to safety with cars flying all around her. No obvious sign of electrical mass failure, lights still on, etc. On 3/24/2023 I received a call and was told the engine needed to be replaced, the cost was $32k, and that the warranty’s fine print says that the warranty will only cover up to the fair market value of the car, which they determined to be about $21k. I’m responsible for their faulty engine & poor mechanical workmanship? I was sent pictures of debris and springs sitting in the bottom of the dropped oil pan and a separate photo clearly showing a disintegrating cam shaft / lower engine area adjacent to the oil pan. Catastrophic and very avoidable failure (this is not an engine in a military vehicle or motorsports vehicle). I believe the problem was never the Mass Airflow Sensor, it was the alloys used in this area of the engine that were failing. This failure is not the first for Infiniti (have been reading forums)

ON 6/13/2020 THE DRIVE BELT SHREDDED WHILE DRIVING UNDER 30MPH, UNDER LIGHT ACCELERATION. AT FIRST, THE BATTERY LIGHT ILLUMINATED ON THE INSTRUMENT CLUSTER, FOLLOWED THE CHECK ENGINE LIGHT. WHITE SMOKE BEGAN TO COME FROM THE ENGINE. THANKFULLY, I WAS NEARBY MY HOUSE AND MADE IT THERE SAFELY. FURTHERMORE, THE ENGINE OVERHEATED DUE TO A COOLANT HOSE BEING KNOCKED OFF BY THE SHREDDED BELT. ADDITIONALLY, THE WATER PUMP AND A/C COMPRESSOR FAILED. THE PULLEY TENSIONER ASSEMBLY AND BELT WERE REPLACED UNDER MANUFACTURER'S WARRANTY, ALONG WITH THE AFOREMENTIONED FAILED COMPONENTS. ALL WORK WAS DONE AT GRUBBS INFINITI OF GRAPEVINE, TX AND THE REPAIR TOOK EXACTLY THREE WEEKS TO FIX. THE FAILURE MILEAGE WAS 28,660. PREVIOUSLY, ON MARCH 6, 2019, INFINITI OF VAN NUYS, CA, TIGHTENED THE PULLEY TENSIONER ASSEMBLY DUE TO A SQUEAKING NOISE I WAS HEARING WHILE ACCELERATING. VEHICLE MILEAGE WAS APPROXIMATELY 10,000. I WAS INFORMED THAT IF I HADN'T HAD THIS ISSUE FIXED BEFORE MY DRIVE BACK TO TEXAS, MY DRIVE BELT COULD HAVE SHREDDED. AFTER THE DEALER ADDRESSED THE CONCERN NO FURTHER NOISE WAS HEARD AT ALL. THE DEALER ALSO INFORMED ME THAT THIS ISSUE IS KNOWN AND HAS BEEN DOCUMENTED IN INFINITI SERVICE BULLETINS. ALTHOUGH, THIS POSES A MAJOR SAFETY CONCERN AS THE VEHICLE COULD HAVE STALLED AT HIGH SPEED RESULTING IN AN ACCIDENT AND OR LOSS OF LIFE. I WORRY THIS ISSUE WILL HAPPEN AGAIN. TWO TIMES, TWO MANY!

Jun 21, 2024

Nissan North America, Inc. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.

Consequence & remedy

Consequence: A broken driveshaft can result in a loss of drive power, or a vehicle roll away when the vehicle is in park without the parking brake applied. Both scenarios can increase the risk of a crash.

Remedy: Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact INFINITI's customer service at 1-800-662-6200. INFINITI's numbers for this recall are R24A5 and R24A7.

Consequence & remedy

Consequence: The lack of an image in the back-up camera display increases the risk of a crash.

Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated.
