Questions to ask the seller
- Were recall 11V538000 (visibility) done? Ask for the dealer printout, or check the VIN.
- Any slipping, hard or late shifts, or a transmission warning light? Ask for transmission fluid service records.
- Does it accelerate and hold speed smoothly, with no surging or stalling?
- Infiniti sent dealers 132 repair notes for this car. Was this one done: “The clutch pedal on an applied vehicle does not return to its normal (rested) position”?

How serious. Out of all 14 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 4K to 20K miles (6K to 34K km) on the car (12 of all 14 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
When I am braking and coming closer to a stop, my car gives a jerk along with an increase in engine speed. Sometimes when I brake I can feel the foot brake stuck for one second.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
