2018 INFINITI Q50 Complaints

My car wouldnt start and when it did, it would start shaking and every time I accelerate, The speed wasnt going any faster but only the RPMs were

I was driving down the highway leaving the barbershop and my car wouldnt go over more than like 55 mph and I got a flashing green symbol beside my check engine light which had just came on when the AUTO (Stop/Start) light did. once I got home turned it off and turned it back on the for a second the light doesn’t come on but once you drive it maybe a quarter of a mile or less it come back on and the car wont function properly again

Car has white smoke coming from the exhaust and the oil level keeps decreasing. Car stalls and takes time to accelerate P0106 code pops up from engine. There’s a rattle and whine noise coming from the engine bay. Also the gas was stuck accelerating. Had to switch the car to neutral so it does continue accelerating. After switching to neutral I was able to decrease power to the wheels and had to pull over on the road.

The contact owns a 2018 Infiniti Q50. The contact stated that while driving at an undisclosed speed, the "Low Oil Pressure - STOP", message was displayed, and the contact stopped driving the vehicle. The contact stated that while starting the vehicle, the engine was abnormally loud. The contact stated that the low oil pressure warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the timing chain. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 107,000.

The locks on the car automatically keep locking all day long and drain my battery, I have had to have my car jump started and recently towed to Infiniti dealer and they are stating there have been known issues with this electrical problem with rain getting into the sunroof and deteriorating the lines that short out the other systems. I have a bumper to bumper warranty that I took out with the Infiniti Dealership but they are stating only part of the repairs will be covered by the warranty and not the sunroof part and that will cost me $1,300 to fix. If this is a known problem, how is this not a recall and why do me, the consumer, have to pay out-of- pocket for something that is a known issue with the sunroofs on these Infiniti's? Can someone please contact me regarding this issue asap. It started when my car was at Infiniti's body shop in September getting repaired from a hit and run to my vehicle that required replacement of rear left back panel and rear left back passenger driver door (that had nothing to do with this issue) and when I picked the vehicle up they had to jump start my car. They had my car for a month and nothing prior to this was wrong with my vehicle. I don't know if someone left my sunroof open and it rained or what happened since this repair, but now I am having the issue with the car locks automatically/continuously locking and draining my battery. I read online that there is a button that should be available on the dashboard to shut off the automatic locking system, but the dealer has not mentioned this and is stating I need all this electrical things done to my car that will cost over $3,000 and that the sunroof part is not covered. This is absurd and not trusting what I am hearing from the dealership. Please advise asap. Thank you for your time!

I was driving down the highway and my car started to shut down and started to make a knocking sound inside the engine bay, putting at risk other drivers, so i turned on my hazards and pulled to the shoulder of the road,the car wouldn’t turn on so i called a tow truck. Took the car to dealer and stated engine is seized

I was in my car waiting my for complex security gate to open when I heard a loud noise. I got out of my car to see what it was and turns out my sunroof exploded. For no reason. No rock or item hit my car nor was the car in motion. It was also not from the heat as it was 60 degrees outside. I called my warranty and they refuse to cover it because it is glass. I am reading many others with this same issue. How does a 6 year old car have the sunroof explode??

The airbag passenger light is illuminated causing air bag system to remain off until resolve. The vehicle was taken in for inspection and dealer confirmed diagnostic results found Occupant sensor malfunctioning. Under warranty, the sensor was covered, but after installation the system also found that wasn’t the only thing to replace. It’s a handful of sensors and harness that is integrated within the seat frame with the ONLY solution to replace the entire chair/seat frame. This item does not fall under warranty. My concern is the safety of my family riding in the vehicle. This issue was happening to 2016 and 2017 models that were recalled for the same issue. Unfortunately this vehicle may have been manufactured in 2017, but holds the 2018 year on paper found through carmax.

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.
