Google search shows Mazda has common problem with their front sensing camera, people are reporting the issue for different Mazda models across the board for the last few years including newer models as well. My car display shows few malfunction warning messages. Following captured from mymazda app. 1. Forward sensing camera malfunction. I-activesense advanced safety and driver support systems may not operate correctly. 2. High beam control system is disabled. Automatic switching between high and low beams is unavailable.
Lane departure warning activated and attempted to correct during a gentle curve. The location had shifted lanes due to construction, so clear lines were visible but not the actual lane to follow which is a frequent occurrence in new york city. The system came close to steering me into the adjacent lane occupied by another vehicle forcing me to fight the correction. There was a lane departure warning on the dash and I believe the blind spot indicator was on (I. E. The adjacent vehicle was detected in some capacity). I considered this especially dangerous as in this zone also had very tight lanes so my physical correction could have also caused an accident. There was no malfunction of the physical components. No dealer or service center has reproduced the issue however I have discussed with other drivers of the same line (2020-23 Mazdas) who have had similar experiences leading to a decision to disable these "safety" features. Mazda provides a reasonable description of scenarios where lane departure and assistance will disable itself due to poor conditions or low confidence. I would recommend at a minimum requiring the system to detect and potentially differentiate lane widths, as city driving sometimes has extremely tight lanes (for example, the inner roadway of the williamsburg bridge where two adjacent lanes are perhaps 8-9ft with less than 2ft on either side to the wall). In these scenarios, any steering correction at all is more dangerous than if it were off.
