Does ‘Honda Sensing’ Make the Vehicle Harder to Drive?

Honda's integrated suite of safety systems, known as Honda Sensing, can be thrown off by bright, sunny days. It also has multiple malfunction points as referenced in TSB #17-064

Honda Sensing is a group of modern safety systems aimed at helping to monitor changing road conditions. Honda describes it as “an intelligent suite of safety and driver-assistive technologies designed to alert you to things you might miss while driving.” That suite includes:

  • Lane keeping assist which adjusts the steering to help you keep centered in a detected lane.
  • Adaptive cruise control which maintains a set following interval behind detected vehicles.
  • Road departure mitigation which adjusts steering and braking if you cross a detected lane without signaling.
  • Collision mitigation braking assist which applies brake pressure when an unavoidable collision is determined.

Common Complaints About Honda’s Safety Systems

The system produces false positives on bright, sunny days and triggers warnings, particularly when driving towards the sun. This can also happen in heavy rain or fog. Additionally the system has been known to malfunction on extremely hot days.

The adaptive cruise control forgets to adapt when approaching other cars, which is a classic case of never rely on your car’s technology.

Others have complained that the system needs to be recalibrated after having the windshield replaced and that isn’t always covered under warranty.

Millimeter Wave Radar Software TSB #17-064

In August of 2017, Honda released TSB 17-064 titled MID Displays ACC, CMBS, LKAS, RDM, and Brake Warnings and Other Listed Symptoms.

The bulletin confirms many of the problems owners have experienced:

  • Front radar blindness due to severe weather conditions (rain, snow, fog, etc) may trigger a sporadic false “Radar Obstructed” message.
  • The vehicle speed fluctuates at highway speeds when adaptive cruise control is set.
  • The multipurpose camera unit temperature is too high resulting in error code DTC B2A60-98.
  • The millimeter wave radar malfunctions resulting in error code DTC U12B7-00

Other areas where the system may break:

  • If there’s brake actuator malfunction (error code U0416-68) the collision mitigation system might trigger a warning.
  • If the steering’s neutral position can’t be determined (error code DTC C0051-54) the lane keeping assist system might trigger a warning.
  • If the integrated driver support system malfunctions (error code DTC P2583-76) due to misalignment.

The TSB informs technicians to update the wave radar unit’s software for the 2017 CR-V EX, EX-L, and Touring.

CR-V Lawsuit

In May of 2018, a class-action lawsuit was filed on behalf of 2017 CR-V owners. The lawsuit says that Honda Sensing, which is standard equipment for the 2017 model year, makes the SUVs more dangerous to drive due to defects in the software.

Allegedly the systems regularly cause numerous warning messages to intermittently appear, and the CR-Vs fluctuate their highway speeds without warning when adaptive cruise control is set. In addition, drivers are allegedly alerted to hit the brakes immediately although no obstructions are present.

The lawsuit points to TSB 17-064 as proof of defects.
