2024 MAZDA CX-90 Complaints

Vehicle is in normal mode with EV mode engaged, car is going 70mph and suddenly accelerator stops working and decelerates to ~60mph until vehicle suddenly aggressively switches to gas mode and accelerates again.

Both lower front control arm ball joints squeak when turning vehicle at slower speeds. Squeaking sounds were noticed at 970 miles. Dealer applied grease as a temporary fix per Mazda TSB #02-002/23. This is a family SUV and I take my wife and kids in it. I am concerned that this is a safety issue as there is a high chance of the lower control arm ball joint failing resulting in inability to steer vehicle in the proper direction. Please look into this issue. Thank you.

CX90 PHEV Premium Plus new purchase 12/2023. 1/24/2024: "Hybrid System Malfunction, Have the vehicle Inspected " On a busy freeway with big rigs and other cars during rush hour traffic (5:25pm), going about 70 MPH. Only 1700miles on car so far. 50-60 degrees Fahrenheit outside. 2mi left on charge, full tank of gas. Car completely unable to accelerate all of the sudden on busy highway once this light came on. Was able to pull off to shoulder, albeit challenging as unable to accelerate and navigate through fast cars in right 2 lanes. Was able to restart car, and go at limp speed but unable to get fast enough to merge back. Called tow truck. Car towed to Mazda dealership. Then unable to get off flatbed of the tow truck as would not go into reverse. Tow guy called me and the staff at Mazda called their Service Manager, had to reset that code. (Something glitch kicked in and locked the car from being able to shift gears). Mazda Service was responsive, worked on and got diagnostics the next day. Stated that it was a computer system glitch. So they restarted the whole system. light is gone and car drives during their testing. They can't explain it. So computer and electronic glitch and system misread leads to a MECHANICAL malfunction that stops the car to be able to be accelerated on freeway. I am a mom of 3 young kids, and lucky I am alive.

What component or system failed or malfunctioned, and is it available for inspection upon request? "Hybrid System Malfunction. Stop Vehicle in a Safe Location." Car completely inoperable. Had to tow to dealership as would not start or go out of park. Hybrid and High Voltage battery issues reported by multiple owners. This happened less than a month into owning the vehicle and with less than 1200 miles. How was your safety or the safety of others put at risk? Car deceleration on highway specific to this error reported by multiple owners. Has the problem been reproduced or confirmed by a dealer or independent service center? Uknown. Currently being serviced by dealer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Currently being inspected by the Mazda dealership I leased the vehicle through. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? "Yes, just a week into having the vehicle (at 300 miles) a "Hybrid System Malfunction" error message appeared to "Have the Vehicle Inspected." Dealership had it in their Service shop for over 2.5 weeks and said nothing was wrong with it.

The car has an "Engine Malfunction" emergency light that goes on. I brought the car into the dealer right away - the car had $1k miles and is brand new, so it's quite scary to get this message. They cleared the error and told me not to worry about it, but were unable to provide a solution. It recurred immediately (within 1-2 days). I reached out to the service department and they told me to ignore it (that there is no fix in progress). My car is unable to change the Mi Drive mode (so it can only stay in Hybrid mode). This is unsafe and goes against the intended use of the car. For example, on a very cold day like today, I wish to warm the car in sport mode (aka not hybrid or electric) and I was unable to change the mode.

When driving on the highway next to a large truck or semi and on a curve, the adaptive cruise control thinks that there’s a vehicle in front of you and slams on the brakes. This has happened a few times with my vehicle. Thankfully, there were no vehicles immediately behind me, or the results could’ve been tragic.

Vehicle engine suddenly loses significant power, the car violently shakes and the engine starts knocking. When attempting to bring the car to a safe location, the vehicles brakes wouldn’t work. Then the car displayed a bunch of errors, like “Engine Malfunction” and “Hybrid System Malfunction”. The car has been in service twice for this issue and they haven’t found a fix. This malfunction has happened twice during our commute with our children in the car.

Driving to work the dash lit up with warming signs stating electrical leak detected, Malfunction to hybrid system stop car immediately and contact dealership. Once stopped the car locked up. It would not start would not engage in to gear. There is no neutral gear bypass. We were stranded. Called Mazda roadside assistance and it took 9 hours for a tow truck to arrive. Tow truck had to drag the car up onto flatbed since there was no way to put it into gear. We we're in the city limits not out in the middle of nowhere. The car is currently at the dealership awaiting parts.

During cruise control engagement when passing a larger vehicle the system sometimes will execute aggressive braking potentially causing an accident with a vehicle following behind. Have to be ready to disengage cruise control during all situations with other vehicles in proximity. It will always perform the aggressive braking maneuver when passing a semi-truck on a curved highway.
