Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My low beam headlamp system has now failed at two separate times, both during nighttime driving. The first was on november 2, 2009, at 37,600 miles, the left hid ballast failed; nissan repaired the failure under warranty although its time-portion had expired. The second failure was at 47,600 miles on december 1, 2011. Nissan/Infiniti consumer affairs were told and acknowledged that mileage warranty was no-where-near expired - but time had - yet, talked as though they would help with the repair. The quid-pro-quo was that I get an Infiniti dealer to verify problem and cost to repair. …”
