Exploding passenger side mirror

I am equating “incidence rate” only based on what I’ve found in public domain. There is clearly a defect with these mirrors, in my opinion as well as others. If something is defective, it should be looked into and not just dismissed as trivial and unimportant. And a primary reason why reporting agencies exist.

Lexus sold over 95,000 RX-350s in the U.S. alone, just in the year 2010, over 93,000 in 2009, over 84,000 in 2008, and over 103,000 in 2007. While the number of incidents you found on the internet may seem high, it may not be as high as it seems when put into context.

Repot it to NHTSA. If there truly is a high incidence of these mirrors self-destructing, that’s the agency that will compile the data and, if it deems it to be safety-related, act on it.

Then get it fixed and move on. It isn’t worth obsessing over.

And that’s not including the millions of other car sold with self dimming mirrors since around 2000 or so ( Audi, BMW, Mercedes, infinity, GM,) more then I can name. Like I said previously the percentage of failures of this sort (probably less than .001%) is not even on the mirrors’ manufacters radar much less the auto dealers.

As TSM said if it makes you feel better report it to the NHTSB and/or go up the Lexus chain with it. Then go to your local auto recycler and pick up the replacement glass for less than $50. I picked up 4 interior self-dimming mirrors with compass and temperature at mine for $60. I just wish I could find the exterior ones for my 02 Camry but it looks like they just are not made.

I appreciate all of your comments and perspectives and I have already done all of the above. As many folks pointed out to me, independently, what if someone is sitting in the seat with the window down when these types of explosions occur? Depending upon the severity of the explosion - shattered pieces of glass/mirror as well as other bits and pieces (as has been reported) could hit their face and cause significant injury.
Technology is a wonderful thing but issues do arise. I hope this forum has brought some awareness to this particular one. Thanks again. Cheers.

Thank you, db4690! :slight_smile: I appreciate your support and others in this forum for expecting to be treated with respect and not dismissed, especially from the dealership where said vehicle was purchased, coupled with the fact that someone in their service dep’t told me that it was covered under my extended warranty and to come in and get it fixed! When I brought the vehicle in, the service rep assigned to me was arrogant, uninformed (couldn’t even give me any details about what the extended warranty did & did not cover), and was just plain idiotic for what he said about both mirrors needing to have exploded & flying out of their casing simultaneously in order to be legit. As someone else inferred earlier in this forum, he should have just manned up and admitted his lack of knowledge about said issue.

They have already lost my business and I will never go back there nor to any other Lexus dealership. I had prior issues with them regarding the quality of their customer service, but I thought I would try & give them the benefit of the doubt with this particular issue. I was encouraged by the conversation that I had with the person over the phone and TRUSTED what he told me. That was my first mistake and the last one that I will ever make with them again. You live and learn… :slight_smile:

The Same Mountainbike: I am a scientist & genetic engineer and I am always interested and fascinated in trying to understand how things work & why things do what they do, especially when they fail. 90% of what we do as biologists fails; we get used to failure, trust me. Hence, I have a very natural curiosity about what is causing these sorts of explosions. In my case, I don’t know what happened first - i.e., did the mirror crack and the release of the liquid/gel trigger some sort of electrical short/explosion that caused the whole mirror to come flying out of the casing OR did the explosion happen first, which then caused the mirror to crack? I can say, that in the San Fran bay, temperature fluctuations are infrequent. The day this happened, it was a classical SF morning, ~57 degrees, which is the norm (high 50’s to low 60’s) year round.

I’m assuming your side mirrors are electrically heated to keep them clear in freezing weather? I’m wondering if the heating system malfunctioned and got stuck on, causing a large pressure build up in the liquid, and eventual explosion.

Ljohnson, it’s good to know there’s another naturally enquiring mind on the forum. At my age it seems like the only thing that delights me is making sense out of something that isn’t obvious. Often even when I apply everything I know, something still makes no sense. It’s hard over the internet because I can’t get my hands on the parts (and a SEM) to analyze and/or to run tests and experiments.

Most of science is failing. It is what causes us to know we still need to know more. It’s what shows us how little we know. It’s what drives us.

Thanks for posting.

@ oblivion - It’s a great question whether the heating system may have malfunctioned and I’ve wondered that myself. I’m not sure what would have activated it to turn on in the first place, though, as the vehicle hasn’t been in freezing whether since Thanksgiving.

can we find a production/mechanical/engineering drawing for this mirror?

This happened to me tonight. Defrost on full for the first time since I bought the truck. Boom!! Glass on road and backplate on side of road. Not a soul in sight and nothing to possibly hit. Not an ounce of damage anywhere. The heated mirror just exploded. Loud as hell. Freaked me out. Glad to see I’m not the only one but I’m thinking I may just buy the part because my dealer might think I’m a loon.

Geez had to go back to see what I said four years ago to get the OP upset. Haven’t changed my mind a bit. Shattering windows, mirrors, blow outs, loud noises, and other unexpected situations must all be handled without panic and driving off the road. Keep your cool and maintain control. Take a cue from how pilots react in an emergency situation with engines flamed out, etc. They don’t go nuts but try everything to maintain control.

Hi ljohnson,

I was one of those people searching on the internet today, to see if anyone else had experienced this exploding passenger side mirror. This past weekend, I experienced it, and I could not find any evidence I hit something in the road, or something hit me.

I have a 2020 Jaguar we just bought about 3-months ago. I was traveling down the highway this past weekend and after making a left turn I heard this same type of explosion as you did!

My husband took it into my Jaguar dealership today and they indicated I must have hit something, or something hit me. I do not believe this is what happened but what else can I do, it is a professional word, against mind; for now, I need to get it repaired for safety.

But I am afraid this is an issue I believe should be investigated further; it really sounds like a defected parts issue. I was lucky I was not hurt or hurt someone else, but it was a very horrifying and nerve-racking experience. I really don’t want this to happen to me again or anyone else!

Nevertheless, the car dealers and the repair shops apparently don’t seem to see this as a big deal or an issue to be looked into. I have found from the research, on the web today, there are many others who have had this happen as well, which has helped me to realize I’m not going crazy! However, this is the only website where I could post this issue.

I am hoping if enough folks keep letting others know this is happening, evenly it will gather enough data to where this issue can be recognized as a problem and something can be done to make it safer for us all! One can hope!!!

One more case here. Happened 5/26/2020 My situation occurred exactly as the others have described. “Explosion” is the only adjective that correctly describes what I heard. The mirror housing is intact and suffered no damage. Here’s the twist in my case. I now have a 24 inch crease in the door of my month-old 1992 Acura NSX. The crease runs from near the front door gap to the middle of the door. The only other factor that I can think of is that it was raining and I was changing climate control, dealing with defroster and air conditioning… I will see my body repair guy shortly. Will be interested to see if he has experienced this in his many years of fixing vehicles. Wish there were some good explanation. ljohnson, you are not crazy!

Yours is the first case that has the same element that I had of fooling with the climate control at the time it happened. I’m almost convinced there is a ink between climate control and exploding mirror and it is an electric issue causing the explosion.

electric mirrors? even if they are I think that’s a stretch. I feel like that’s more likely to be a coincidence

Which means you HIT something or something hit you. How can a 1992 NSX be a month old? Do you mean you’ve owned it for a month?

I do not understand how people can make a fuss over a glass part that hangs off the car in a vulnerable spot but costs less than a hundred dollars to a few hundred to replace. Replace it and move on.

I have a 2018 Lexus Nx 300h, that we bought 2 years ago and had been bringing to the dealership for maintenance. Recently on August 31st, 2020 my right handside mirror exploded with wires hanging out and mirror popped out- luckily I was a block away from my house running about 5mph, or my mirror would have flown in the freeway and may have coz an accident.
Brought to the dealership but they said that I might have hit something since there was this thread like dent- (which could have happen due to the mirror popping out of its case.)
Still does not make sense to have a side mirror exploding. Its like if your car gets even the tiniest dent your mirror might explode.
The dealership claims this is not covered by my warranty due to what they claim something flew or hit the side mirror. I keep on telling them - I was the driver nothing hit the vehicle.
Hopefully this manufacturer take this seriously before any accident happen.

We are glad to see some posting about this incident and to support Ljohnson that this is really happening. Our Lexus 2018 NX300 H is another incident. I hope that the dealership will take this seriously that might cause an accident to some drivers. The sound of explosion is very loud like a .45 caliber gun shot. and the driver will be out of focus due to the explosion.

To those who have had this happen to them – it is very real. It doesn’t look like I ever posted a follow-up to what happened.

  1. As I summarized in various posts above, I posted my story to Lexus’ Facebook page, including how my car dealership responded (or lack thereof). They promptly replied asking me to contact them via their less public company website, which I did.

I then received this response from Lexus:

  1. In my case, they said they didn’t know whether the mirror cracked first and the auto-dimming fluid produced an electrical short that caused the explosion and the mirror to come flying out of the casing, or if the explosion happened first, resulting in the cracked mirror. The mirror was still attached via some of the electrical wires.

The fluid also ruins the paint so you have to get that buffed out and repainted. So the damage extended beyond the mirror, which resulted in the cost of the full repair to be significantly higher.

  1. As I was going through this, I was also told that dealerships generally make more money from their service/repair sector rather than from the sale of vehicles. In situations like mine, I was told that dealerships will make you pay for the repairs, and that they may also have the ability to submit their own claim for reimbursement, thereby effectively getting paid twice. The only way someone can uncover whether this happens is through the litigation discovery process.

  2. Your best recourse is to make the serious safety issue PUBLIC. Post to social media – both the car manufacturer’s and your own personal social media sites, AND tag the car manufacturer as well as the US DOT NHTSA and ODI (see point 3 above).

Please contact your local investigative news teams.

  1. Saving the best for last and finality – it is only because I posted to Lexus’ Facebook page that I ultimately was taken serious and they repaired the damage at their full expense!!

After 3-5 days, a Follow-up Specialist’ from Lexus contacted me. I took my car to another dealership in the bay area (I refused to go back to where I purchased the vehicle based on how they treated me), and they provided me a loaner vehicle to drive. Lexus then sent a team of people to that dealership and they thoroughly examined the mirror. They took my claim serious but also went into their investigation thinking they would prove I hit something and that I would be held responsible.

Well, their investigation proved that I did not hit something and no one shot my mirror.

They ended up repairing the mirror as well as repairing the paint on all of the damaged panels from the caustic fluid.

  1. For those who still doubt this is a very real thing, please do not.

For those to whom this very unfortunate thing has happened — please fight and make them do the right thing.

And please report to the US DOT NHTSA. Nothing will be done to help people and bring this issue to light if they don’t receive the complaints and can track trends.
