2019 Acura Rdx

On February 7, 2024 I called insurance and filed a claim for my vehicle that was sitting in my driveway at the time of the incident. Upon getting in my car, the rear windshield, which had no chips, breaks, lights, etc. imploded into my vehicle. They stated they believed this happened due to the defroster. It was repaired using insurance at a certified local glass repair shop. Today, 11/14/25 I was making a turn from a stopped position and yet again the rear window imploded into my vehicle. The rear window had no issues at the time of implosion and is parked safely inside a garage to prevent weather effects. This is a VERY clear safety issue as I have a car seat in my back seat that are all rear facing and the window has now imploded TWICE. Acura acknowledged this, and as provided so hasn't the NHSTA. But the safety concern is refusing to be fixed and I cannot continue to have a vehicle that the rear glass implodes within two years causing potential harm to children, and back seat passengers.

On Wednesday, November 5th, the rear glass on my 2019 Acura RDX spontaneously shattered without warning. I brought the vehicle to Safelite for repair; however, they were unable to assist due to the technical complexity of removing and replacing the glass. I then contacted an Acura dealership by phone and was advised that I may be required to replace the entire rear hatch, rather than just the glass. I have since learned that Technical Service Bulletin (TSB) 22-014 acknowledges an issue affecting rear-glass failure, but it is limited to certain 2019–2020 models and VIN ranges. No recall has been issued, despite numerous reports of this same defect. Additionally, there is an ongoing class-action lawsuit related to this issue (Tyzcko & Zavareei LLP). I am submitting this complaint because Acura is refusing to repair or replace the shattered rear glass despite its being a known design defect. This failure represents a serious safety hazard, as occupants seated in the rear of the vehicle could be severely injured if the glass were to shatter while in motion. I believe Acura must be held responsible and required to issue a recall, as well as provide repair coverage, especially for vehicles now out of warranty. I respectfully request that NHTSA investigate this issue due to the clear safety concerns and growing number of similar incidents.

We have owned our 2019 Acura RDX for about 4 years. Roughly 2 years ago my wife called me panicked that the car had lost power and the check engine light was on as she was exiting the freeway. It was a rainy day, she had our kids in the car on the way to a soccer game. I called off work with an emergency, drove an hour to where she was and scanned the car. No codes popped up on my scanner, I started the vehicle and it seemed to run like normal, no check engine light. I had it towed to Honda of Gresham, OR and after a week or so they called and said they couldn't find anything wrong with our vehicle. I paid for a oil change, a tow and a dealer diagnostics and was told they could not find anything. $500 later no answers. Fast forward 2 years Oct 26th 2025 I was driving the RDX this time, in the rain on the freeway. Wife and kids in the car. Went to accelerate past a slow driver and the car went into limp mode. Check engine light flashing and limited to 40 mph or so, I put the hazards on as I was on a single lane bridge with traffic behind me. I pulled over after the bridge and turned the vehicle off. After 5 minutes or so I started the car again and everything seems fine, no check engine lights nothing seems off. I continued on down the freeway without any more incident. I started researching what is going on and find many many reports of this same thing. Acura has a tsb for a front mount intercooler as the fix, but when I took ours in for the stated problem they couldn't find a problem. This car looks beautiful, but it's a safety hazard on the freeway when moisture is present, we live in the PNW and it rains 7 months out of the year. I have owned 10-12 hondas in my lifetime and this 2019 Acura RDX is the worst. Absolutely a safety hazard to my family. Disappointed this will be the last Honda we buy.

Upon exiting my car, I heard a loud crashing sound. The rear windshield had completely shattered upon closing the driver side door and glass was everywhere. Had my rear windshield decided to spontaneously implode 5 minutes earlier while driving on the interstate, I most likely would have had a bad car accident. Acura has a service bulletin out regarding this, as it’s a known issue. They refuse to cover cost or do a recall on this known safety issue. Someone is going to get killed when their back windshield blows out driving and they think they’ve been shot. Absolutely terrible and irresponsible on Acura/Honda’s part.

On July 12, 2025 my husband, the driver, and myself, owner of the vehicle and passenger this day, were driving on the freeway at approximately 7:00am in the middle lanes of the freeway. Without any codes or warnings beforehand, we heard the car make alarming beeps and automatically loss all power to the engine while traveling at highway speeds. This situation put my husband and my lives at risk and in a dangerous situation as there was traffic on a busy freeway and lost all power to the vehicle and made even maneuvering off the freeway a dangerous action as we had no warning beforehand there was something wrong. My husband was able to get us safely out of harms way. After being diagnosed at a mechanic, it turns out this problem happened due to a cracked cylinder head and had no previous warnings of an issue and no warning lights on the vehicle alerting to a problem, I will have the cylinder head in my possession and the mechanic I took my vehicle stated it cannot be ruled out this could be a manufacturer’s or casting defect. I tried contacting Acura Corporation about this situation but was told that since I did not take it to a dealership and have a certified tech look at my vehicle, there will be no case and no type of remedy or reimbursement for this situation.
