Mazda cx 5 lane departure warning not working

I recently purchased a new 2021 CX-5 Touring. All in all I really like the vehicle, but I have a couple questions about the lane keeping and alert system.

I took the vehicle on an 8 hour trip today, and after 5 hours of trying to convince myself that the active lane keeping assistance was doing something, I turned it off. I discovered that not only had it not been helping me stay centered in the lane, it was actively making it harder to drive on the highway. As the owner of a 2018 Hyundai Elantra that has LKAS, which is absolutely amazing, this is a major letdown to say the least.

Is there a factory calibration of the radar and camera system that was maybe not done, or done improperly at the dealership?

second item is more of a comment than a question.....the lane departure warning is totally useless and too soft to feel. You have to be way over the lines to active it, complete junk. Really sad that Mazda failed so badly on these important features.

Ya - the problem in the automotive industry is that there is no standardization in ADAS (Advanced Driver Assistance Systems) naming. Speaking of "Lane Keeping" - there are now 3 different types of systems available...

1. The old passive systems - detect lanes and warn you (only) when you drift outside of them, with no corrective steering torque being applied by the system.

2. The more recent *active* systems - detect lanes and attempt to correct you if you drift out of your lane. These systems do not try to "auto-steer" for you - but only try to correct your path by applying corrective torque if you drift into the lane markings. Often they tend to ping-pong you back and forth inside the lane.

(In the case of Mazda (the "Driver's Car"), Mazda tries to keep its LKA system "non-intrusive" (so it doesn't risk losing its "Driver" fans, who tend to want to be in charge of the "driving" and steering). The result with Mazda is you must steer all of the time - and as long as you stay more or less centered, the Mazda system will never interfere by applying any corrective torque. This is clearly their design intent. Unfortunately for Mazda, most other auto manufacturers have moved forward and also offer a newer *auto-steering" type of active Lane Keeping as described next).

3. The newest systems * (Lane Centering), detect lanes and attempt to completely *auto-steer* for you, keeping you centered between the lane markers. (Like Tesla Auto Pilot and Cadillac Super Cruise). These systems do not wait until you drift out of the lane, but apply steering torque continuously to keep you centered in the lane.

Unfortunately for we consumers, it is almost impossible to tell which type of *Lane Keeping Assist* a given vehicle has without actually driving and testing it yourself. And more discouraging, many auto journalists (and Youtube reviewers), don*t offer any detailed help, they simply report that a given vehicle has *Lane Keeping" and other safety assists.

What drives me crazy is listening to some of these so-called auto- journalists complaining that the Lane Keeping is *too intrusive*, when in fact (if it is really a Lane Centering system), of course it is intrusive, that*s what it is designed to do, steer for you! Duh! It's as if most auto- journalists are still unaware of the growing importance of these Driver Assist Systems, and are still locked into only testing zero to sixty and other ancient behaviors.

The Blind Spot Detection problem

I bought a 2021 Mazda Cx-5 from ramsey Mazda of des moines, IA. It offered comparable comfort & features. A selling point was the safety features touted by the salesman. Odd things occurred during the first few months but I attributed it to a learning curve.   Read details...

The Warning problem

The adaptive cruise control system (collectively including the lane departure warning, forward collision warning, Smart city brake support etc. ) on this SUV stops working abruptly and randomly while the car is in operation on the road.   Read details...

The Assist problem

Heading south doing 70 mph on 95 in the far left lane on a rainy day . . . . Came over a hill and started to hydraplayne. . . . . Seems like the automatic pilot took the car over ,,,,,I lost the fight with the steering wheel and did two 360s all away across 4 lanes of traffic to the grass   Read details...
