FORWARD COLLISION AVOIDANCE: WARNINGS
Near a roundabout the car in front of me started moving and braked. My car didn’t give any forward collision warning or proximity alert before my car hit the other car from back. The speed was less than 12 mph.
NHTSA complaint #11688748 — an unverified report by a vehicle owner.
LANE DEPARTURE: ASSIST
The Mazda CX90 PHEVs i-activesense system that controls the adaptive cruise, lane departure and lane keep assist system disables at random times with a message "i-activesense temporarily disabled. front radar obstructed." There is never any objects obstructing the radars and no outside weather/elements affecting it. It will not turn back on either, even though it should turn back on if the obstruction is cleared from the radars/sensors. Since there isnt anything to clear when it happens, it stays disabled unless the vehicle is turned off completely and back on. I have had this vehicle for 2 weeks and it has disabled on the interstate traveling 70+ mph and on city roads in congested traffic over 15 times. When it happens with the cruise control enabled, it immediately begins decelerating quickly, causing a safety issue when on the interstate at high speeds. Was brought back to service 24 hours after acquiring the vehicle but Mazda cannot seem to figure out what is wrong with it. Its a huge safety issue when it all disables and the car quickly decelerates without any warning. Has happened on multiple dates, at least 15 times in 2 weeks, at various speeds with 75 mph being the fastest.

BACK OVER PREVENTION: WARNINGS
The backup camera did not beep as I backed into a mailbox. The emergency braking also did not activate. The following day when I used the backup camera it was displaying an image of somewhere I had parked prior (it was not the real time image). The wrong image stayed displayed despite turning the car off and back on multiple times.

LANE DEPARTURE: BLIND SPOT DETECTION
Blind spot monitors alert for things like light fog. I cannot trust a system that thinks water vapor is going to be an issue while turning or merging.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The vehicle does not slow down or reduce speed until the brake pedal is pressed at least 1/5 of the way down when using cruise control. The brake light turns on, but the car continues to accelerate.

LANE DEPARTURE: BLIND SPOT DETECTION
1. Gear Shift Issue in EV Mode: The transition from 1st to 2nd gear is not shifting properly in EV mode. At times, the gear jerks during critical situations, which compromises control. 2. Power Output on Highway: While driving on the highway, there are instances where there is no power output when flooring the accelerator to overtake. 3. Engine Malfunction Light: The engine malfunction light has come on and off three times. 4. Radar Malfunction: The radar system is intermittently not working or working improperly. The radar malfunction light also came on and off once (i-ACTIVSENSE system malfunction). The last safety recall was completed a few weeks ago, but the issues are still ongoing. Since then, I have visited the Mazda dealership twice, but they let me go, dismissing my claims and saying they couldn’t duplicate the problems. I have a case with Mazda corporation. Nothing done yet (Case Number: [XXX]). The name of the Representative is Candy. I would appreciate it if you could investigate these issues at the earliest convenience. Thank you for your attention to these matters. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

LANE DEPARTURE: ASSIST
steering wheel locks into the direction of turning (sometimes more than needed for the corner) and causes over-steering at all speed (from 20mph to 45mph). at low speed the steering can be forced to turn back, but at higher speed such as onramp or offramp, after fighting the oversteering, the steering disengages for a brief second while fighting oversteering which I think can/will cause inexperience driver to turn the steering wheel too much in the opposite direction. also the lane departure/centering feature also causes the steering wheel to jiggle while driving straight (incorrectly trying to move the car while going stright). this is going to cause accident.

LANE DEPARTURE: WARNING
with lane-keep assist /lane-centering enabled, the steering will try to straighten the car while turning. experienced this during on-ramp and off-ramp of highway. this is super dangerous. even experienced it at low speed in the neighborhood. steering wheel will fight me during turn and disengage for brief second - this is very disconcerting while making a turn. even with lane-keep assist disabled, I can still feel the wheel (very minor feedback) trying to change course while turning. this issue began immediately after dealer performed all active recalls.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Mazda Radar Cruise Control - while on [XXX] and passing a truck that is in the right-hand lane, especially on curves, my CX-90 PHEV system brakes, but there is no vehicle in front of me. It has difficulty determining what is in front as opposed to on the side, especially through curves. This happened more than once. I almost got rear-ended due to this issue.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On July 15, 2024 this vehicle at 50 mph on cruise control suddenly flashed white warning words indicating problems with the cruise control and immediately thereafter started flashing “hybrid malfunction” and to return to service dealer. At the time of the hybrid malfunction warning which was right after the quick cruise control warning, the engine operation, specifically the gas pedal no longer delivered power to vehicle, either electric or gas. Additional warning was to pull off to the side and stop and turn off vehicle. This occurred and vehicle was pulled to the side put into park and turned off. Waited approximately 3 to 5 minutes and restarted the engine which started in gas with no electric although there was electrical charge on the battery. Was able to continue to our final destination approximately 15 minutes later and no more than 10 miles driven. Hybrid malfunction was still visible on the dash to include the warning stating that vehicle needed to go to the service department. Approximately an hour later, vehicle was turned on again with the same warning about the hybrid malfunction, however, engine started in electric. Drove vehicle to dealership and stated what happened. Dealership the next day stated that this was a phantom code known by Mazda, but no problems associated with the code. Vehicle picked up per service advisors request two days later. Mazda dealership stated that headquarters had eyes on this particular vehicle. A day later after the pick up Mazda dealership requested vehicle be brought back for a “DC box” repair. Dealership stated this process would take a week or thereabouts to replace this component. Vehicle currently in dealership service.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My car senses a vehicle in a lane to the left or right of me as a vehicle in my lane and slams on the breaks. There is a recall on this with Mazda, but not for my manufacturing date yet. It's very dangerous. Occurs all of the time

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
When cruise control is active but slower than set speed vehicle will full throttle acceleration to get to set speed creating a situation where loss of control of the vehicle partially occurs. If this happened in wet or winter conditions loss of vehicle control is very possible.
