Odometer Fraud. The contact purchased a 2018 Infiniti Q50. It was discovered that there were three separate mileage discrepancies. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 50,370; however, at the time of registration, it was discovered that the mileage had been rolled back from 54,000 to 28,630 miles. The mileage before the vehicle was purchased was 47,650.
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!
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.
