general problems of the 2026 Honda Passport

The driver-side rear roof rail housing/bracket on my 2026 Honda Passport is loose. The affected section is exposed to wind while the vehicle is moving. The roof rail component has already been replaced once, but the replacement component is noticeably looser and appears to fit worse than the original component that was previously installed. The issue has therefore persisted despite a replacement, and the condition of the replacement is worse than that of the original part. I am concerned that the loose roof rail housing or bracket may become progressively dislodged under repeated wind exposure and vehicle vibration. If the component detaches while driving, it could create a road hazard or pose a risk to other motorists. I am requesting that NHTSA document this complaint and evaluate whether this condition reflects a recurring component defect, inadequate retention, or an installation or fitment problem affecting other vehicles of the same model year. The component has already been replaced once, and the replacement has not resolved the concern. I believe the recurring nature of this issue warrants further evaluation rather than treating it solely as an isolated cosmetic problem.

Like many others have reported on the internet, I am now seeing the tt04 message on the dashboard inidicating that a software update was interrupted and I must see the dealer. This is concerning in that this bug has been reported for years and Honda has failed to find a solution. What exactly is not working in the car with a failed update? what must a dealer do to fix the update and is the car safe until then? no answers from Honda in two years.

I just bought the brand new vehicle about a month and a half ago. Went on a vacation in [xxx] national [xxx]. I was cruising along xxx in [xxx], smooth highway, no one near me, great weather, and all of a sudden, there was a huge boom sound so loud, and glass fell down on me, I looked up and my sunroof had exploded and shattered, while the shade was open. I never saw any vehicle near me or bad weather or problem. Just cruising speed on an open highway. I read online and have been told this is a known occurrence with sunroofs in Honda Passports, and have researched online seeing it happen to others. I pulled over and called my Honda dealership. The recommended a crash wrap and to close the shade. I couldn't get it wrapped until I got home to [xxx], and my dealer did that. The shattering occurred on xxx about noon. It was scary, and I had glass in my hair, lap, and all around me in the car. No issues prior that I was aware of. I was looking straight ahead on the open highway when this occurred.

Driving from [xxx] to [xxx], just over 1hr into trip @ 100 miles out of town and on one of the many steep inclines on the route, the engine power seemed to pulse, as if increase and decrease of gas/acceleration, then has every single alert possible illuminated on dash with the bell sound: electric power steering system problem, steering assist reduced. Electric parking brake system problem, parking brake not available. Brake system problem, brake performance may be reduced. Brake hold system problem, apply brake when stopped. Vehicle stability assist system problem, reduced traction and handling. Trailer stability assist system problem. Hill descent control system problem, apply brake when descending. Hill start assist problem, vehicle may roll upon brake release. Adaptive cruise control system problem. Collision mitigation braking system problem. Road departure mitigation system problem. Low speed braking control problem. Emission system problem, avoid heavy acceleration and high speed. All wheel drive system problem, only front wheels may be powered. All alerts ending with 'see your dealer' the car then had reduced power which was a significant safety concern and driving risk when navigating hills and traffic flowing at 75mph uphill while this vehicle going slower and slower regardless of gas pedal pressure: 65mph, than 60mph, than 55mph, than 50mhp eating gas like crazy. Coasted into gas station to asses. At low speed there was a rattle upon pressing gas pedal coming from under the hood. The vehicle is 3 months old and has 4,197 miles. It is not simply that the alerts illuminated, those systems were all affected: braking, steering, acceleration, lane departure, cruise control etc. All were not working. Heavy acceleration and high speed were not even an option. Somehow made it back to [xxx] in limp/aux mode. Dealer has had vehicle for 6 hours and no update other than, 'it's not the battery' information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On 8/23/26 with 700 miles the panoramic shade would not close all the way. When used the button to retract, there was some loud clicking. I was able to guide the shade to close, but the shade has a sag on the front right.

The vehicle's infotainment system displays an ota software update error message on every startup. Honda dealerships are unable to correct this issue without further intervention and software updates from Honda corporate. Dealer has stated that this issue may interfere with reliable over-the-air software updates, including any potential safety-related updates delivered through this ota system.

Auto stop / start system. When engaged and engine turns off like at a stop sign, once I press on accelator engine will ratttle, sputter and sometimes steering wheel will briefly lock or turn all before it comes back on completely and is ready to drive. This has happened several times to me. Has almost caused a crash after I attempted to pull onto a cross road in traffic. The system cannot be permantely deactivated.

My passenger rear panel window just cracked out of nowhere. Nothing hit it, it just completely shattered.

The sunroof shattered without any impact issue, while we were driving down the road at approximately 65 mph. If the sunshade had not been closed the driver and two passengers would have been showered in glass risking serious injury. The driver would have been challenged to maintain control risking serious injury to those in his vehicle and others on a busy highway. High risk incident. I'm from iowa and purchased the vehicle in des moines. The sunroof failed in just north of greeley colorado, and I had to have the repairs completed in greeley, at the Honda dealer. The dealer claims that "glass is not a warranty item" unless I can prove a defect existed. Well, the sunroof essentially exploded and there's not much left to be able to prove the defect. My dealer in des moines would have supported a warranty claim. No one other than the Honda dealership in greeley colorado has inspected the damaged parts. There was absolutely no warning that the sunroof was about to fail catastrophically. We were driving at ~65 mph in hot weather ~95 degrees, when a sudden heavy rain shower occurred, along with a corresponding sudden drop in temperature; 15-20 degrees, and we heard a very loud bang on the sunroof, like a baseball bat hitting the roof, and then we could hear glass shards on top of the sunshade. I pulled off the road and examined to sunroof to see that it was completely shattered or exploded. Fortunately, the rain stopped as suddenly as it started, and we located a Honda dealer in greely and had them make repairs as the vehicle was not drivable with the sunroof shattered. Initial price quoted was $1,218 and the final price a week and a half later was $4,101. Honda denied my warranty claim, and insurance denied claim since there was no hail.

The seat memory of the vehicle will reset itself every few days. This is while using the same key fob and driver profile. Android auto does not stay connected wired or wireless. This is after the vehicle has been factory reset, new cables used and phone reset. Buzzing/ grinding noise while breaking blind spot sensors do not beep while the setting is activated to beep.

Only 4200 miles and receiving tt04 error which appears, from social media, has been ignored by Honda or just no fix and any fix by the dealer would be temporary. Very disappointed, Honda has always been my car of choice. My dealer is not convenient to me, especially if I have to continuously return to them due to same issue, in which Honda has no answer for.

Tailgate glass shattered spontaneously.

Purchased vehicle November 27th, 2025 took car to the carwash after owning a few months and noticed after the car wash the paint was chipping. Took to dealership was told "OH those are door dings or something to that effect", filed with Honda was told basically the same thing. So, started doing research and came across the NHTSA website to file a complaint as well as the ncds informal dispute settlement program. I have never had a new car or even a used car have the paint chip off when using a car wash. In doing my research it appears this particular make and model with the orange paint is a known issue. I didn't pay the price for this car to be unable to keep it clean. I am also filing a complaint with the state attorney generals office, this car is still under warranty.

The vehicle system keeps throwing code tt04 for a failed over-the-air update. The tech specialist indicated there is no current fix for the issue other than restarting the ota system, disabling the auto-update function, and not checking for updates. This issue has been going on for over a year. I would like to bring attention to this annoying problem that other customers are experiencing as well.

It’s not an incident. Looking out the windshield has a slight distortion, that looking through it, it seems like looking through a low grade prescription glasses. I have reported it to the dealership and they took note of it and mentioned that they will check it. In terms of safety, it puts some strain into my eyes while driving.

Tiny rock hit windshield and immediately cracked the windshield a foot long. Driver side internal upper door panel foam seems to have blistered and created bubbles/hump.
