“My power steering belt snapped off. Prior to that, my brake pedal was loose enough to move it up and down roughly a 1/4 of an inch with my foot. The only way to engage the cruise control was to hold the brake pedal up with my foot, then in order to keep the cruise control engaged was to keep holding the brake pedal up with my foot because it would sense that the driver slightly tapped the brake pedal to disengage it if I stopped holding it up manually. I had to have the brake pedal bolt tightened. …”
NHTSA complaint #11190493, filed 2019-03, 72,000 miles“First instance: while driving on the highway going 60mph my car powered down, preventing me from controlling the car. The gauges and lights inside the car went dark and MPH went to 0. I lost electrical power and after 1 minute the car is back to normal. Second instance: as I was pulling into a driveway and went over a bump the car lost power and powered down, I naturally pressed the gas before I understood what was wrong, the car powers back up as I'm pressing the gas and caused me to almost hit another car.”
NHTSA complaint #11255221, filed 2019-09, 53,000 miles“I am experiencing software related issues that have become increasingly dangerous. In sum, the Infiniti software shuts down or locks up forcing me to become an it technician while driving.

Here's an overview of my experiences for the past 3 years: randomly, the software will shut down leaving me without my instrument panel (speedometer, tachometer), climate control and audio control. …”
NHTSA complaint #10992920, filed 2017-06, 38,000 miles“Traction Control did not function when needed. I had my breaks and rotors replaced two days prior to the accident, which may have had an impact on the performance of the vehicle. Insurance representatives did look over the vehicle, as it is now in their possession. However, I do not feel as though they took the time to look into my concerns. There was no warnings on the Dash.”
