2024 HONDA ACCORD Unknown Or Other Problems

The vehicle's infotainment system displays error code TT04 on every startup, preventing over-the-air software updates, including any potential safety-related updates delivered through this system. The TT04 error appeared immediately following completion of fuel pump recall service (NHTSA campaign 24V-763) on 4/12/2025. The vehicle exhibited no infotainment or telematics issues prior to this recall service. This suggests the recall repair procedure either was performed incorrectly or has an inherent flaw that damages the Telematics Control Unit (TCU) communication system. When I returned for subsequent recall service (NHTSA campaign 25V-785), the dealer dismissed the issue as 'normal' and refused repair, only offering to address it after I filed a formal complaint with management. This pattern suggests dealers are aware this is a consequence of recall work but are systematically dismissing customers rather than correcting their errors.

OFFICIAL COMPLAINT — HONDA RECALL NOT BEING FIXED Subject: Urgent Safety Complaint – Recall Cannot Be Performed by Any Honda Dealer To: American Honda Motor Co., Inc. – Customer Relations I am submitting a formal complaint against Honda because I have an open safety recall on my 2024 Honda Accord Sport Hybrid and no Honda dealership is able or willing to perform the recall repair, leaving me driving a potentially unsafe vehicle with no timeline for resolution. Summary of the Issue •I originally scheduled the recall repair with Braman Honda of Lake Worth, and they canceled my appointment the day before, stating they could not perform the recall. •I then attempted to contact Ed Morse Honda, who did not answer multiple calls. •When I called Honda Customer Service, I asked to escalate to a supervisor, and was denied. •Honda assigned a case manager, but scheduled a repair appointment for me without confirming my availability, at a time I could not attend. •When I called Ed Morse Honda to reschedule, they informed me that they cannot perform the recall because the software required for the update is not working. •I was told to simply “wait,” with no timeline, no workaround, and no assurance of safety. Safety Risk This recall involves a system failure that could cause the vehicle to stall or shut down unexpectedly. I am now: •Driving a car with an unrepaired safety recall, •Receiving warnings from my insurance company that the recall must be completed, •Feeling unsafe and potentially liable for an accident if my vehicle fails due to Honda’s inability to perform the recall.

When making a left turn, my car suddenly bucked up onto the air feeling like I ran over a big obstacle which was not the case. Car came to sudden stop and I was thrown forward over steering wheel. Thankfully no one was behind me or it would have been catastrophic. The first week I owned the car, when going through a car wash, the car started jumping up and down and wouldn't move forward. Had to back out of carwash. Dealer told me it was the collision mitigation system and to turn it off before going in. The "brake" light on dash periodically flashes when no cars are in front of me. I am truly afraid to drive this car which only has 5,800 miles on it. Dealer can't find a problem. I am turning off collision feature every time I drive, but what if I forget? I believe this is an extremely dangerous defect and should be looked into. It doesn't always happen, but when it does...

I get an error message every time I turn start my car up, the error message says there is no software updates available every since I purchased the car. On numerous occasions the sign reader have read 85/95 mph on different occasions.

The car a few moments after starting up will say its not able to perform an System update, the dealer said this was due to a issue communicating with the servers in Japan, however this issue has been on going for about 2 months with little sign of it going away.

Purchase New Delivery date: August 13, 2024 On Saturday June 7, 2025 after temperatures reached 93⁰ I noticed a cracking in windshield starting from plastic cover near windshield wipers. The cracking rapidly spread upward which is currently about 8 inches in length. This windshield hasn't been struck by any object. If windshield is replaced with any windshield other than a OEM from Honda it will void warranty on camera system. To replace with a OEM from Honda I was quoted over $2,000.00. This cracking has started due to poor materials used in the production of windshield or is either too thin. There is numerous reports of such on Honda 11th generation forums.

This has to do with the wireless phone audio system. The quality is extremely poor as the internal microphone seems to pick up every sound in and outside of the car. There appears to be zero filtration of outside noise. This is a safety problem as it forces the driver to pick up their phone in order to use the speaker.

I was driving down the highway when my sunroof exploded out of no where. No debris hit my vehicle. The explosion was extremely loud and spontaneous. My safety was put at great risk as there is nothing I could have done to prevent this problem. As I am going 75 miles an hour with vehicles behind me, my glass exploded. This glass could have fallen onto me while driving, seriously injured ,or even, and killed me. Luckily my sun shade was closed. The debris from my shattered sunroof could have seriously injured the vehicle behind me.

On Wednesday, Oct. 2, 2024 at approx 7:45 am, I started this car with approx 3,900 miles and every available warning light in the dash cluster illuminated (see photos I’ve attached). I immediately shut off the vehicle and waiting several moments, then restarted. It appeared even more lights illuminated. I attempted to immediately drive the car to nearby honda dealership but the car’s shifter was locked in park, the steering wheel was also locked dead center. Had it towed to dealer and it has been there one week now. Honda has no answers. They told me honda North America is involved and even they do not have an answer. Right now I have serious safety concerns, specifically will steering lock at interstate speed? That situation with an entire family onboard would be tragic.

2024 Honda Accord EX 11th generation Due to poor design and engineering and the use of low-quality plastic pipes to carry gas fuel vapor to the (evap system) and brake fluid to the braking system, these pipes have resulted in safety issues, both involving the possible loss of braking and high chances of fire when they are compromised. All these pipes run parallel to the exhaust system, which gets extremely hot. Due to the plastic brake, gas line, and evap line being exposed to road hazards, it's allowed direct contact with road debris, in which I encountered in my 2024 Honda Accord EX Turbo. The Honda engineering team should have known, reasonably expected leaving such thin plastic pipes exposed under the undercarriage of the car would most likely result in costly repairs in which they would, therefore, deny any responsibility for damages occurring. The local Honda dealership can't repair these damaged pipes due to liability issues. The pipes can't be coupled together, so the entire length of these pipes must be replaced at a cost of $7,035.52. American Honda has calculated the repair time and charges for any necessary work need, these charges are universal throughout all Honda dealerships in the United States. Due to car being under warranty one is unable to seek repairs elsewhere without violating the the 3 year/ 36000 factory warranty for other covered parts. Having to report and claim such damages on my auto insurance policy shouldn't be an option. An insurance company shouldn't have to pay to replace damaged fuel and brake lines due to the poor engineering of an auto manufacturer. The financial burden on owners is significant, and having such issues as this increases all our insurance costs. This could have resulted in me losing brakes and fire starting as both exposed fluid lines run parallel to the exhaust and have no cover/ guard to aid in protection. I've contacted American Honda, they absolutely refuse to accept any responsibility for damages.

The 2024 Accord EX front passenger seat sits too low and has no height adjustment. Many adult front passengers are positioned extremely low to the floor with zero height adjustment. I believe the airbag may not effectively protect or even cause injury to these passengers as many can not see over the dash. This abnormal low position also causes leg discomfort and cramps during longer trips. I recommend that Honda provide a seat adjustment alteration or install optional seat-jacking spacers to restore passenger height to a safe and or normal position.

Bought a brand new Honda 2024 at a dealership, since picking up the car we noticed it was black and white and not clear, assumed it was a setting issue so paperwork was completed and we took the car home. It was a safety issue as having it black and white and reversing it was hard to see and several close calls on collition when backing up due to camera malfunction. Issue persisted, notified dealership and appointment was made to replace camera. Issue was confirmed by dealership and camera replaced. About to exit the dealership, put car on reverse and issue persisted.
