Subject of Complaint: Severe odometer fraud, mileage tampering, and title misrepresentation by the selling dealership: Phenix Motors, LLC ([XXX]), operated by [XXX]. The Discrepancy: The vehicle was sold to me with a falsely represented odometer reading. Subsequent electronic diagnostics and vehicle history reports reveal that the actual mileage is severely discrepant from the mileage disclosed on the official bill of sale and title paperwork provided by Phenix Motors, LLC. The dealership has since explicitly refused to participate in state-level consumer mediation with the Mississippi Attorney General's Office.Current Status & Evidence Location: The vehicle is currently completely inoperable with a dead dashboard/ECM display. On XXX, the financing lender, Magnolia Federal Credit Union, executed a repossession of the vehicle. Under the FTC Holder Rule, the lender is fully aware of the fraud claims. The physical car and its electronic control modules (the core evidence of the fraud) are currently being held by the lender's agent: United Auto Recovery (Account reference partial VIN: [XXX]).State Action & Reference History:Mississippi Attorney General's Office: Consumer Protection Division File closed due to Dealer Principal's ([XXX]) formal refusal to mediate.State Licensing Authority Contact: [XXX], Mississippi Motor Vehicle Commission / Mississippi Department of Revenue (Title and Dealer Enforcement Division: [XXX]).Request: I am requesting a formal federal investigation into Phenix Motors, LLC for systemic odometer manipulation, and a formal safety/title flag placed on this VIN to prevent the lender or dealer from washing the title or liquidating the vehicle at auction before the electronic evidence can be audited.

NHTSA complaint #11744237 — an unverified report by a vehicle owner.
COMPONENT/SYSTEM FAILURE: Timing chain and timing chain tensioner/guide assembly failure. The timing chain has stretched prematurely, causing the vehicle to fail to start, loss of acceleration response, check engine light illumination, and audible rattling noise from the engine compartment. The failed components are available for inspection upon request at the dealership. SAFETY RISK: The vehicle would not accelerate when the gas pedal was pressed, creating a dangerous situation where the vehicle could not respond to driver input. This poses a serious safety risk in traffic, highway merging, or emergency evasive situations. Additionally, the failure to start leaves occupants stranded without warning. DEALER CONFIRMATION: The problem has been diagnosed and confirmed by an authorized Infiniti dealer. The dealer determined the cause is timing chain stretching and has quoted $6,500 for repair, which includes timing chain, tensioners, and guides replacement. PRIOR WARNINGS: Approximately one week prior to complete failure, the vehicle began exhibiting a rattling noise from the engine. The check engine light illuminated. Shortly after, the vehicle would not start and would not accelerate when the gas pedal was pressed. KNOWN DEFECT: This is a documented defect. Infiniti Technical Service Bulletin ITB19-027a addresses timing chain-related diagnostic trouble codes on 2017-2024 QX60 vehicles with the VQ35DD engine. The timing chain tensioner and guide failure on VQ-series engines is a well-documented premature wear issue affecting vehicles well before expected service life. At 80,000 miles, this failure is premature and indicative of a design or manufacturing defect, not normal wear. REQUEST: I am requesting NHTSA investigate this safety defect and consider requiring a recall for affected Infiniti QX60 vehicles. Nissan/Infiniti corporate has declined goodwill assistance despite the existence of TSBs acknowledging the issue.

While driving, the vehicle often brakes and accelerates without my control. I've reported this issue before. My brakes are fine, according to the vehicle status.
NHTSA complaint #11689590 — an unverified report by a vehicle owner.
2020 infinity qx 60 Bought car used in 2024 with 80,000. There is a hesitation when accelerating and sometimes seems to want to die when idling. There is also a knocking sound at times when accelerating. At times I feel transmission skips. When turning right or left or reversing, the wheels seem to creek and almost grind a bit. I am great about maintenance and called to determine if my vin was included in the current recalls. I am told no, but am experiencing the same symptoms described by infinity. Just want to know if there is a any action to take to ensure my 4 kids and I are always safe when traveling and dont end up with thousands in repairs.
NHTSA complaint #11674135 — an unverified report by a vehicle owner.
This vehicle started shaking and juttering at a lower speed and made it very difficult to drive. Then I could accelerate and it would not go faster. I took it to a repair shop and they were getting CVT codes for the transmission. I looked online a found that many other people had these same issues as well as a Class Action Lawsuit that was settled a few years ago for 278 million for these problems. I was never informed that this CVT was a problem and could have it replaced from Nissan for no charge. I am not sure why Nissan would allow an unsafe transmission to be installed into a vehicle that would make the car unsafe to drive.

In the beginning when I pull off the car shudders and jerks speed was delayed. Now in the middle of driving with some speed the car beginnings to strain and barely move although the gauge shows I’m going 40 miles the car is straining and going under 5 miles. This started maybe a year ago but now it is much worser.

Vehicle looses power randomly. No engine or warning lights. RPMs will rev but car will not go into gear or drive. I can shut off the vehicle for a couple hours then restart and will drive fine until randomly happens again.

The vehicle shudders and the transmission shifts up and down and has a high squeal when driving. The transmission does this cold and at operating temperature.

NHTSA complaint #11524768 — an unverified report by a vehicle owner.
The car jerks forward when accelerating from a stopped position which throws everyone in the car forward and it could potentially hit something or someone. The car does not stay in position when put in park or even turned off. It rolls back 2 feet and it hit my daughter and knocked her down from the rear and the car door hit my mother because it rolls back too far. Also, it has a major hesitation when trying to accelerate. When trying to pass a vehicle I almost got hit from a car behind me. These problems happen in every 2023 Infiniti QX60. My car is currently in the shop trying to be for the second time but each loaner car has the same problems. One infiniti service manager said the jerking forward is a “global problem” in this model.
NHTSA complaint #11515597 — an unverified report by a vehicle owner.
FEB (sensors) display on our Infiniti QX 60 dashboard - this occurred within several months when we received the car. The car was inspected by their Infiniti Repair dealer and was told the problem was solved. It was not and the same issue appeared after several miles of driving. Reported to Consumer Affairs at Infiniti and was informed its an Infiniti Dealer issue. Further electronic defects occurred as I was not able to change gear from Park to Drive. Infiniti towed the car to their Dealer and purportedly they corrected. The same issue continued and placed several more calls to Infiniti Consumer affairs. Was told "we are sorry but we cant help you". Eventually brought this issue up to the highest level at Infiniti to [XXX] - head of Nissan North America. No action yet again - and was called by an assistant and thanked me for bringing it to his attention. informed Infiniti via email to [XXX] that it can be catastrophic at Front sensors are defective and do not function. I have video's and written correspondence to Infiniti. I am available for a Zoom call or can be contacted at [XXX].

NHTSA complaint #11486977 — an unverified report by a vehicle owner.
The car does not accelerate or accelerate with jerky motion. Occasionally, the vehicle disengaged out of drive mode and would not accelerate. There seems to be some transmission issues as the vehicles is making jerky movement upon acceleration. Almost cause accident on a turn as it could not move forward out of cross traffics!

NHTSA complaint #11459851 — an unverified report by a vehicle owner.
The vehicle on at least 4 occasions has stopped accelerating when driving the vehicle (first time I believe was fall 2021, this last time was Spring 2022). Most of the times that the issue was noticed, the car was was moving at slower speeds (35 or less). The engine remained running but pressing on the gas pedal didn't make the vehicle increase it's speed. The first time it did this we took it to the dealership to inspect. They could not replicate the issue and they said that no error codes showed up. We left with no repairs or answers. It happened 2 more times after that. Each of those times we were able to stop the vehicle and get it to go again or it would start to respond to pushing on the gas pedal and would accelerate. The 4th time this happened I was in the middle of an intersection turning and it wouldn't accelerate. I was able to slowly roll into a gas station. I tried stopping and turning the vehicle off and on again to see if the problem would go away, however each time the car only slowly inched forward. I parked and then the vehicle started acting weird. The AC shut off and the steering wheel locked. There were three error lights that came on. The first said "FCW Malfunction See Owner's Manual" and second was "IBA OFF" and then the "! inside a triangle" appeared. These appeared only after stopping the vehicle for the last time right before it wouldn't start again. The vehicle was towed to the dealership. The error reading they got was c1601 and they believe the alternator needs to be replaced. This doesn't seem to line up with the issues we have been having nor the error warning lights that appeared. The last time this happened my child was in the car with me. Had we pulled out to turn and the car wouldn't go we could have very easily been hit by oncoming traffic. It is very troubling that the dealership doesn't seem to really know what is wrong with the car.
NHTSA complaint #11458867 — an unverified report by a vehicle owner.
I bought a 2014 INFINITI QX60 and after one week, my vehicle started to jerk after resuming from a stop sign or stop light but was just annoying at first. Later that day, the check engine light came on and I took it to auto zone to get the code which displayed "P1715 - Input Pulley Speed Signal" and secondary DTCs were P0776 (Pressure solenoid B performance/stuck off. When I am driving, I cannot make it a mile without having my RPMs skyrocket and my vehicle become inoperable and makes me turn my flashers on and find a place to pull over, shut off my vehicle, and restart it. This repeats over and over and over if I continue to get to the grocery store for essential needs but it is not safe to drive and will for sure cause a collision if it keeps happening. There are so many issues with this make/model and needs to be addressed for the safety of others on the road and myself/children as it is unexpected and very scary.
