Infiniti’s defect patterns track two pieces of hardware: the JATCO continuously variable transmission and the VC-Turbo engine. The CVT — shared with parent Nissan — generated years of shudder, hesitation, and whine complaints in the QX60 and older sedans, with repeat fluid services and valve-body replacements that often did not hold. The 2.0-liter VC-Turbo in the QX50 and QX55, the industry’s first variable-compression engine, has drawn complaints about rattles, stalling, and outright failures. Model-by-model detail is on our Infiniti problems and recalls hub.
The InTouch dual-screen infotainment system rounds out the complaint file — freezes, reboots, and backup-camera dropouts that produce the “could not duplicate” repair orders familiar to any electronics case. Infiniti models have also appeared in federal campaigns for backup cameras and brake components.
Infiniti’s warranty is four years or 60,000 miles basic and six years or 70,000 miles powertrain — a longer window than most rivals. A QX60 that keeps returning for transmission shudder inside that window is a textbook repeat-repair case: insist each visit’s order describes the symptom in your words, and keep the stack complete.
If your Infiniti has been in the shop repeatedly for the same warranty problem, or has spent weeks out of service, you may have a lemon law claim. Get a free case review — it costs nothing unless we recover for you.
