2024 HONDA ACCORD Electrical System Problems

The contact owns a 2024 Honda Accord. The contact stated that on several occasions while driving at undisclosed speeds, the vehicle unexpectedly came to a stop without the brake pedal being depressed. The “BRAKE” message was displayed on the instrument panel. The failure occasionally occurred while the cruise control feature was activated. The contact received notification of NHTSA Campaign Number: 25V785000 (Electrical System). Additionally, occasionally the electrical system was inoperable, and the instrument panel failed to function properly, and the trunk and fuel door unexpectedly opened. The contact also stated that the automatic door locks failed to function properly, requiring several attempts to enter the vehicle. The vehicle was taken to several dealers; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failures, and the contact was offered a buyback option for the vehicle. The contact expressed concerns that, due to the multiple failures, the vehicle was unsafe to operate and created a hazardous condition, because the vehicle was almost in a crash with children inside the vehicle. The approximate failure mileage was 33,000.

Mileage: 33,000

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 telematics error appeared immediately following dealer service department 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.

Purchased new. Delivery date August 13, 2024 I've experienced an ongoing issue with the electronics since owning car. First issue was ECM failed. Currently having problems with the Lane Keeping Assist (LKAS). The car is alerting me that I'm not staying within my lane which isn't correct, the car then attempts to correct. The car attempts to correct, shows a lane departure warning but won't give any audible alerts as previous. During the time car alerts of road departure it clearly shows the car diagram within the road diagram. I have pictures taken showing such.

The Instrument Panel Display combined with the Front Sensor Camera failed. This risked my live as well as others lives on the road due to the ill ability to predict when it will fail as well as the difficulty to control the sporadic behavior. The Lane Keep assist system would also overcorrect and have very strong and hard to control corrections with the wheel. The Instrument panel would also turn off mid drive and I would not be able to see my speedometer. It has been seen by multiple diffferent Honda Service Centers and no one can figure out the issue. Camera issues have been recalled on previous models.

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.
