The picture
Is the Acura ADX or Honda Accord more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Acura ADX
The Acura ADX is a low-volume, newer model with only 5 complaints over 2 years and no recalls on record. The reported issues cluster around the panoramic sunroof—shattering glass and water leaks—plus inconsistent walk-away door locks. With so few complaints, it's hard to call any pattern definitive, but the sunroof problems are the most concrete owner-reported failures.
Honda Accord
The Honda Accord is a high-volume vehicle with 4,524 complaints over 10 years, 38 recalls, and reports of crashes, injuries, and deaths. Owner complaints span engine stalling, electrical failures, and forward collision avoidance malfunctions. The sheer number of reports and recalls suggests a more complex ownership experience with a wider range of potential problems.

Owners report the panoramic sunroof glass spontaneously shattering and blowing inward while driving, and water leaking through the roof speaker. These are the most frequent complaints and could mean costly repairs and water damage if not addressed.
One owner reported the automatic walk-away door lock feature operated inconsistently and sometimes failed to lock the vehicle. This could leave the car unsecured, which is a daily annoyance and a security concern.
The same walk-away lock issue also appears under latches/locks, reinforcing that the automatic locking system may not work reliably. Buyers should test this feature thoroughly.
The sunroof glass shattering is also categorized under structure, indicating a potential body integrity issue. A shattered sunroof can be dangerous and expensive to replace.

Owners report sudden loss of power, multiple warning lights (brake, hill descent, ABS), and rattling noises during acceleration. These symptoms can indicate serious engine or hybrid system faults that may lead to breakdowns.
Complaints include simultaneous failure of electronic power steering and braking at highway speeds, and tire failure after TPMS service. Electrical glitches can compromise critical safety systems.
Owners describe the system failing to prevent collisions, with incidents occurring under similar conditions. This suggests the driver-assist technology may not always perform as expected.
There are reports of persistent rotten-egg/sulfur odors and fuel pump issues. These can indicate fuel delivery problems that might affect performance and emissions.
