2016 LEXUS RX

VISIBILITY/WIPER

As I was driving southbound on I five in the state of Washington in Stanwood area 8:00 AM my sunroof exploded, causing me to swerve into other lanes and a distraction for other drivers There were no warnings. The sunroof was in a close position, not being used. The vehicle went into repair today being August 1. We did take pictures. Had there been cars directly on either side of me accident would have occurred.

UNKNOWN OR OTHER

I was driving and pressed the button to close the sunshade on the panoramic sunroof when I heard this like a grinding noise. The cloth sunshade stopped moving. Then I heard a pop noise, and the sunshade came down, and it hit me more on the back of the neck. Then I heard something fall on the floor behind me in the back seat area. I couldn't pull over right away, stopped at a store, and there was a black, plastic and metal piece that was on the floor in back. The sunshade itself was partly hanging off the ceiling where it came from. It didn't hurt but of course it startled me. This happened on Friday going to work 7/18/2025. I haven't used the sunroof for a while because it has been too hot but Friday I wanted some natural air, and opened it up. Researching I see that it is supposed to be all one piece, and everything which includes the entire panoramic sunroof to be replaced which is close to $3,000. I found online that a lot of people have the same problem for years 16-22 on the RX. I found out where the dealers are telling people excessive heat melts the glue holding these adapters in place, and it eventually give way and break. Most people including me park outside, I don't have a garage, and it's summer, this is defective, and it should be covered my Lexus. Since it just happened yesterday, the vehicle wasn't inspected by nobody, there were no warning signs that this was happening either. The safety issue is when it hit me on the back of the neck while I was driving. Thank you for your time.

ENGINE

Timing Cover gasket leak. Apparently this is very common problem with 2016 Lexus RX 350 due to a bad design by Lexus. Lexus is quoting ~7000 to fix

STRUCTURE:BODY

I am formally submitting a vehicle defect complaint regarding my 2016 Lexus RX 450h, which is experiencing premature and extensive paint degradation, including clear coat peeling, flaking, and fading. This issue is not due to environmental exposure or neglect, but rather a clear indicator of a factory defect related to substandard paint application and adhesion failure. This concern directly aligns with known and previously acknowledged factory paint failures affecting both Lexus and Toyota vehicles. Numerous Customer Support Programs (CSPs) and Technical Service Bulletins (TSBs) have been launched by Toyota Motor Corporation to address: •Faulty clear coat adhesion •Improper surface preparation during manufacturing •Delamination and premature degradation of factory-applied paint, particularly in white pearl and other finishes Despite wide acknowledgment of these issues in prior campaigns (such as CSP ZKC and others involving Lexus RX, ES, and LS models), my vehicle’s VIN was not included—despite exhibiting identical symptoms. Given the extensive documentation of these defects, I am requesting the following: 1.A formal investigation into the paint failure affecting my Lexus RX 450h. 2.Written acknowledgment of this known issue and confirmation whether this VIN has been or should be included in past or upcoming CSPs. 3.Immediate corrective action including paint restoration or full vehicle repaint at no cost. 4.Clarification on why Lexus has failed to expand prior paint-related CSPs to include other affected model years and VINs despite continued customer complaints. This message is being concurrently submitted to the National Highway Traffic Safety Administration (NHTSA) for independent review under potential consumer safety, quality compliance, and warranty oversight. I expect a formal response within 10 business days of receipt. Failure to act appropriately will prompt further legal and media inquiries to ensure transparent processing.
