Within that volume, owners reported 19 crashes, 0 fires, 2 injuries, and 2 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 4/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2017 RX350 is service brakes with 9 filings, followed by unknown or other (8) and fuel/propulsion system (8). 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 3 investigation files overlapping the 2017 RX350. 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.

Mileage: 32,000
VEHICLE EXPERIENCED ROUGH TRANSMISSION MOSTLY BETWEEN GEAR NUMBER 2 AND 3 AFTER TAKE OFF. VEHICLE STALLED AROUND RPM 1200 - 1500 DURING NORMAL DRIVE AT HIGHWAY, THEN SUDDENLY SHIFTED FORWARD WITH EXCESSIVE FORCE. ENCOUNTERED VERY DANGEROUS SITUATIONS ON HIGHWAY ON MY RECENT TRIP. I ALMOST HIT THE VEHICLE AT THE FRONT FOR A FEW TIMES DUE TO CONSISTENT ROUGH SHIFT PATTERN. I HAVE TAKEN THIS VEHICLE TO LEXUS DEALERSHIP SEVERAL TIMES TO ADDRESS ISSUE IN THE PAST. UPDATED ECU SOFTWARE DIDN'T RESOLVE THE PROBLEM, AND ALWAYS KEEP COMING BACK. I BELIEVE THIS ISSUE COULD HAVE BEEN RELATED TO RECENT FUEL PUMP RECALL, BUT THE RECALL DIDN'T INCLUDE THE 2017 RX 350 MODELS. PLEASE INVESTIGATE FOR SAFETY ISSUE. THANK YOU.
