Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2005 Q45 is electrical system:ignition with 1 filings, followed by tires (1) and air bags (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 7 investigation files overlapping the 2005 Q45. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

WHEN CRUISE CONTROL IS SET, AND THE NEED TO PASS OR SPEED UP IS REQUIRED, IF YOU PRESS THE GAS PEDAL TO THE FLOOR THE CAR TAKES OFF AND *THEN STOPS RESPONDING AND DROPS BACK TO SET CRUISE CONTROL SPEED WHILE YOU ARE STILL FLOORING IT. IT BUCKS BACK AND FORTH. I SPOKE TO SEVERAL OWNERS ON A INFINITI OWNERS SITE AND THERES PERFORMS THE SAME. ITS DANGEROUS IF THE NEED TO SPEED UP OCCURS. THIS IS A PROBLEM IN THE CODING OF THE PARAMETERS IN THE ECU AND COULD BE DEADLY WITH UNEXPECTED PERFORMANCE. THIS HAPPENED ON I40 IN KNOXVILLE TENNESSEE IN HEAVY TRAFFIC. THIS CONDITION CAN BE REPEATED BACK TO BACK MULTIPLE TIMES.
