2012 Honda Crosstour Electrical System Problems

An aftermarket ignition interlock device (Intoxalock eLERT model) installed in my vehicle repeatedly malfunctioned and disabled the vehicle’s ignition system, preventing the vehicle from starting and operating normally. The device was installed on October 6, 2025 as part of a state ignition interlock program. The first malfunction occurred only four days later. The device has malfunctioned multiple times since installation. The most serious failure occurred in March 2026 when the device would not power on at all. Because the device controls the ignition relay, the vehicle could not start and became completely inoperable. The vehicle had to be towed to the service center that installed the device. The component involved appears to be the ignition interlock handheld breath testing unit and relay system that communicates with the vehicle ignition. When the device fails to power on or function properly, the vehicle cannot start even when the driver is sober and compliant. This malfunction created a safety concern because the vehicle could not be operated or moved when needed, leaving the driver stranded and unable to safely transport family members. The problem has occurred multiple times and appears to be related to the device itself rather than the vehicle. The equipment has been returned to an authorized service center for inspection, and the device should be available for inspection upon request. There were no warning lights from the vehicle itself prior to the failure. The primary symptom was that the ignition interlock device would not power on or would malfunction during operation, which prevented the vehicle from starting. Because the ignition interlock device directly controls whether the vehicle can start, repeated device failures create a situation where the vehicle becomes unexpectedly disabled.

An aftermarket ignition interlock device installed in my vehicle requires “rolling retests” while the vehicle is in motion. During these rolling retests, the device alerts the driver and requires a breath sample within a short time window. To complete the test, the driver must physically pick up and handle the handheld unit and blow into the device while driving. This requirement creates a driver distraction because the driver must remove at least one hand from the steering wheel and divert attention from the roadway in order to complete the breath test. This procedure appears to conflict with Pennsylvania’s hands-free driving law, 75 Pa.C.S. §3316 (Paul Miller’s Law), which prohibits drivers from holding or manually using an interactive electronic device while operating a vehicle. Although the ignition interlock device is intended to promote road safety, the design of the rolling retest requires the driver to manually interact with a handheld device while the vehicle is moving. Drivers may feel pressured to complete the test immediately because failing to do so can be recorded as a violation or trigger lockout procedures. This creates a situation where drivers must choose between complying with the device requirements or maintaining full attention on safe vehicle operation. In my experience, the alert can occur while driving in traffic, which forces the driver to handle the device during active driving conditions. Because this equipment directly affects vehicle operation and driver behavior while the vehicle is moving, I am submitting this report to raise a potential safety concern regarding whether rolling retest procedures create unsafe driver distraction and whether they conflict with hands-free driving safety laws.
