New Car Assessment Program

The 2015LEXUSRX carries 21 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 1 fire, 1 injury, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2015 RX is engine with 5 filings, followed by unknown or other (4) and steering (3). 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.

NHTSA currently has 3 investigation files overlapping the 2015 RX. 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.

Engine cut out suddenly while driving 45 MPH, followed by Battery Light, Check Engine Light, and Power Steering Light forcing hazardous emergency stop. Engine would no longer crank, and car had to be towed to nearest Lexus Certified Repair Facility. Technician scanned the system and found four Codes: P0335, P1603, P1604, P1605. After bore-scoping front three cylinders, technician tried to turn motor by hand and was unable to. The motor turned in reverse, but not forward. Technician removed oil pan to find pieces of valve spring broken and pieces of the piston rings and piston fragments from one of the rear three cylinders. Motor will need to be replaced or completely rebuilt after only 133,458 miles and regular servicing.

2015 Lexus RX450H with less than 60,000 miles Electronic Power Steering Motor needs repair or replacement. The Electronic Steering Motor has an internal 3 piece star-shaped green plastic gear in between two metal pieces used as a bushing/damper. That green plastic gear has become dry, hard, dehydrated, and has crumbled inside the electronic power steering motor. Diagnostic indicators include rattling and vibrations emanating from the steering column that sounds like something is broken inside the steering assembly. Which it apparently is. Moreover, I am particularly concerned about the implications of this denial. The faulty component in the electronic power steering system poses a significant risk, including the potential for complete loss of steering control. This not only jeopardizes my safety but could also lead to further damage to my vehicle or even bodily injury. Given these circumstances, I believe it is imperative that this matter be addressed with urgency.

It has the same engine failure problem as the recall for 2022 and 2023 vehicles. The engine just stalls when it wants with no check engine light or error codes. Then restarts just fine when put in park. Lexus repair could not even find a issue. Have documents to prove it.

One early morning in November, I opened the rear door on my RX to remove my rollator walker. I am handicapped. I opened the door using the switch under the door handle. The door opened normally, and I reached in to remove the rollator and the door jerked down about a foot then continued to close with several jerking drops. It scared me, but I was able to jump out of the way of the door as it dropped. The temperature that morning was in the lower 40’s which was perhaps the lowest early morning temperature we had seen this fall. I feel that the low temperature may have contributed to the problem. I opened the door again with the switch. The door opened fully but closed again in a similar manner as described above. I was able to hold the door up with one hand and removed my rollator with the other, which was rather difficult due to my limited strength. Later in the day, after the temperature rose, the door opened and stayed open as it should. I discussed the problem with my

I was told tread separation was issue. This dealer put my family at Risk! When the car went in for shaking they said the tire was defective. They replaced it and charged me $214, the tire only cost $150 new. I asked if the other tires were OK, the girl I paid said "the bad tire was from a different batch than the three remaining tires and they were OK." 2 weeks later 2 more tires go bad, putting us back in the car with defective tires put my family at risk. This dealer is dishonest and Dangerous. They charged me for 4 new tires total cost $492.35 when the set only cost $600 new and we only received 15% of the use of the tire, before they went bad. 1 tire going bad is unfortunate, 3 tires same problem is a Defect and they should have been replaced NO Charge. Anyway you need to get these tires
