The driver seat electric motor has failed on three separate occasions. 7/29/21, mileage 22,984 9/3/21, Mileage 24156 7/12/22, Mileage 34,414 When the electric motor fails the seat can not move forward or back. Depending on the seat position at failure, certain individuals would not be able to reach the pedals to safely drive the vehicle. This could create a serious safety issue requiring some one to drive without reasonable control. Each time the motor failed it was replaced by the dealer. No warning lamps or indication of failure happened prior to the three times of this severe safety failure. As of 6/18/23 the seat has been working properly. I was in contact with a case worker at Infiniti numerous times ( between 7/11/22 and 8/11/22) and she did not think this was a serious problem, as if I was the only person reporting this issue. This was very troubling to me because it seemed to be a very serious safety issue. The last time I was at the dealer for service work (earlier this year) they revealed to me that this same issue has happened in other vehicles besides mine.
2019 Infiniti QX50 electrical complaints
Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
Multiple repeated problems with electrical system. Repeated crash sensor failure. This mainly happens when it is warm or sunny. The dealership has had the vehicle four times and the problem is still reoccurring. The malfunction light comes on when the car is first started or while driving. The dealership stated that none of the crash sensors work when it is lit. They have replaced the module that was diagnosed to be the problem, however there is still the same issues. They are going to replace the module again. They have replaced a module to control the wipers twice. The wipers still come on randomly when it is sunny, and the delay for the wipers does not work when it is raining. The cruise control stopped working and is throwing codes. This morning`s new warning was shift system malfunction. It's been in three times for the air-conditioner. The cooling fan was stuck on high speed until they replaced a sensor. The car was inspected and the brake pads were okay, however when the car stopped, there was a very loud pulsation. The dealership told me it needed rear brakes, which we replaced, and $600 later, they were still pulsating. After the second time taking it back, the dealer then said it was the tires which were new. We took it to a private garage, and the problem was warped, factory front rotars because they could not support the weight of the car. They were replaced with performance drilled and slotted rotars, which corrected the issue. The dealership cannot figure out the electrical issues, so they keep replacing the same parts and returning it back in a dangerous state. Since the vehicle is throwing so many codes and has so many malfunctions that I feel unsafe driving it. All of these problems problems started December 2019, when the car had 8000 miles on it. It has been to two different infiniti dealerships, neither being able to fix it. We have photos of all the codes, but when we tried to upload, it failed over and over.
On may 4, 2019, I tool delivery of a new infinity, qx50 and after 2.5 months of ownership (july 26, 2019 to present), I'm having ongoing / unresolved problems / failures with; audio, lane departure, collision warning w/ sudden stopping, heated / cool seats, infotainment, audio, tailgate, remote door locks, both screens going blank, phone / bluetooth connection, awd, automatic shifting problems and extremely soft brakes that put me thru 2 controlled intersections. The dcu has been replaced 4 times and I still have the same ongoing / unresolved problems. I told the service manager (rudy), to start replacing all the sensors, cms and camera and he refused to do that. My qx50 has been in for service five times (including today, 04-21-2021), for a total of 6+ weeks. The mechanic at infinity, can't replicate any of my ongoing problems / unresolved problems and I have 25 videos, showing what the qx50 is dong and infinity can't fix it. I pay a lot of money for the qx50 and for all the driver safety features, other amenities and it still continues to fail miserably and does not perform as intended. Because of these unresolved problems and ongoing issues, my wife refuses to drive in the qx50 with me. I have asked infinity to buy back the qx50 and they flat out refused. I had to obtain a lawyer.
Tl* the contact owns a 2019 infiniti qx50. The contact stated while driving at 65 MPH, there was a loud, abnormal popping sound coming from the vehicle. Soon after the popping sound was heard, a bright flashed from the instrument panel. The instrument panel went blank had gone blank with a blue streak across the screen. The contact stated that the vehicle started to decelerate independently. There was also an abnormal odor inside of the vehicle. The contact attempted to open the sun roof however, the sun roof failed to operate as needed. The vehicle was driven to clear lake infiniti (14705 gulf fwy, houston, tx 77034) where after two weeks, the mechanic was still unable to duplicate the failure. The manufacturer was notified of the failure and a buy back was offered. The vehicle was not repaired. The failure mileage was approximately 7,000. The VIN was not available.
Stopped at night, at a red left turn light, 3 lane roadway. No one on road in front, passing me, or coming in opposite direction. Backup camera came on, the picture of the vehicle appeared on the screen, all warning signals came on for an imminent head-on, side-front passenger crash was about to occur. These warnings flashed, then screen totally black. Car was running, in drive, foot on brake waiting for green. No traffic on highway due to hour and location. The screen then flashed back on, same repeat warnings, black screen. Could not get screenshot, phone in purse. Light turned green, turned left across 2 more lanes, into destination parking lot. Screen came back on, stayed 'normal' rest of daytime driving, until 2 days later daytime driving on 4 lane highway, the imminent warning system did not come on when a vehicle in front hit brakes, 60 MPH traffic. I was distracted by a cell phone 'ping', looked down, then back up to see the brake lights, was abe to stop in time. Called the salesperson where purchased, after the first incident, on her recommendation, then service # at certified dealer where I was currently located, 4 + hrs away from dealership where purchased. Was told by this service center rep, 'never heard of this one, but we can get you in on aug 19th. (it was aug 10th at time of my call), if it happens again, get it towed either here, or dealership where purchased.' after the near rear-end crash, with no alert activated, my decision to return vehicle via notice to dealership sales manager was made. Dealership sales manager never responded to my email stating I was cancelling purchase of his vehicle. 2 salespeople were sent to drive it back, despite the recommendation of that out of town service rep. To tow it if 'another incident'. Concerned more incidents may occur with this vehicle, that it will be washed, waxed, returned for sale to another driver.
My wife opened the rear liftgate using the outside electronic door switch on the liftgate. The liftgate electrically fully opened. My wife started to load items into the rear of the SUV. The door electrically closed on its own. The door struck the back of my wife's head before she could get out of the way. The door did not stop or open automatically, or detect an object in its path. She tried to reopen the liftgate using the switch, and it raised about 5 inches and then immediately shut. She brought the vehicle home and told me what happened. I opened the rear liftgate using the exterior switch as she had. The gate fully opened electrically and without stopping it immediately closed. I tried to open the liftgate again and it lifted about 5 inches and immediately closed. She drove the car to the dealer and showed the infiniti of coral gables service department. They repeated the actions, the door opened and immediately closed by itself. I contacted infiniti customer service and they opened incident 36294200. They gave her a loaner car and have requested the dealer not repair the car until a specialist arrives. The car was parked and not running on all three occasions.
Backup camera and nav screen went blank. Couldn't use the backup camera backing up in garage.
