Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Your form doesn't work for me. All systems were affected. I totaled my car while driving up a hill, in cruise control, and I hit a puddle. The car accelerated into the median. I was no longer a driver; I was a passenger.”
NHTSA complaint #10903580, filed 2016-09, 36,000 miles“I have a 2015 Infiniti Q50. I believe I'm experiencing the same fuel pump eco mode problem as the 2016-2017 Q50. Me, my wife and newborn daughter were on our way home on the express way during rush hour in eco mode with approximately 35 miles before empty, we were about 2 miles away from the nearest fuel station. We were traveling east doing about 40 MPH due to heavy traffic when all of sudden my Q50 started to bog down and then eventually stalled . Luckily we were right next to the shoulder. I pull over pop the hood looked everything over and all seemed fine. …”
NHTSA complaint #11246705, filed 2019-08, 76,000 miles“Engine and/or transmission lost torque power. Since 2016 while car only had 11,000 miles all of the sudden car lost torque power while accelerating. Check engine indicator has never light up and dealer consult scanner has never found the issue. Still car doesnt have same acceleration nor torque while going 0-60mph. Already I've seen so far 4 cars of the same year with speed sensor problems and replacement. Mechanics say it begins by loosing power until stops working and car wont move.”
