What 308 owners told NHTSA about the 2024 Mazda Cx-90-mhev

"The steering wheel intermittently sticks and feels resistant when switching lanes or making turns, especially at highway speeds. It does not return smoothly to center, making it feel unsafe and unpredictable. I brought the vehicle to the Mazda dealership, but they stated they 'cannot replicate the issue' and refused to perform any repairs. This is a safety concern because the sticky steering can make it difficult to control the vehicle and could potentially lead to a crash. There are no warning lights or error messages displayed when this occurs. The issue happens intermittently, making it hard to demonstrate on demand, but it is recurring and worsening. Since this is a brand-new 2024 Mazda CX-90, I believe this could indicate a defect in the electric power steering system or related components."

While I understand that tires themselves are typically covered by the tire manufacturer’s warranty, this situation is different. Mazda equipped the CX-90 with Falken OEM tires that are inadequate for the weight and design of the vehicle, leading to premature wear at only 20,000 miles. This is not normal wear-and-tear. My claim is that Mazda bears responsibility for installing unsuitable tires on a heavy SUV, which created a safety hazard.

Decelerating behind traffic my Mazda cx90 shut the engine down. While still rolling traffic began to accelerate and I pressed the accelerator. The engine did not restart. I bottomed out the pedal with no reaction. I completely removed pressure from the pedal then pressed again before the engine restarted. This vehicle has already had a recall repair that seemed to be for this issue

The rear door seals on the vehicle do not seal which allows water and dust to enter the vehicle from the rear two doors. Mazda customer service has been contacted multiple times on this issue and they refuse to address the issue. The dealer it was purchased at said it was a known issue after we had already purchased the vehicle. You can look online and see a bunch of people reporting the same issue with no resolution.

My 2024 Mazda CX-90 brakes squeal very loudly at low speeds. Also when applying brakes it feels like the anti lock braking system is engaging.

The steering column has a stuck/ stickiness to it specifically when turning left. It’s extremely concerning because unless you’re jerking the wheel back the other direction immediately, it’ll stay in place allowing the vehicle to continue turning

Engine Malfunction have serviced. At least 3 times. One of the 3 (so called) repairs took 3 weeks. They said “Tariffs you know Japan”. When I get this warning my car engine seems to vibrate. I have only had my car since August of 2024. New vehicle I am the 1st and only owner. Today is June 22, 2025 and tomorrow will be another incident number 5. My car is doing this again. I am a [XXX]. Most of the time my car is in the garage. But I have to drive 188 miles on the turnpike to visit my son and come back. This is every 3 months or so. My other son drove to South Texas. These warnings always came on. Am I supposed to stay home and only go to the store. I pay over 700.00 a month. This is not good. I am now getting afraid to drive it. So tomorrow I will again have to drive to Edmond Oklahoma and have it repaired again. “Engine Malfunction have services”. I’m so disappointed. My son has a cx-5 and it’s a great car. I’ve had so many loaners. They have been fine. I am told this is a brand new model and we have to get the kinks out? This is at my expense, peace of mind. Please help me. Thank you.

I’ve been experiencing power loss and surges/RPMs drop for nearly a month now while driving at various speeds. Each time, the iStop indicator comes on. This is a serious safety concern. I am extremely worried that the vehicle could stall, especially while my family is in the car, while driving on a busy highway. Undoubtedly, this issue presents a significant risk to the safety of drivers and passengers. I am requesting your assistance in initiating an official recall from the manufacturer for this component failure. Based on my research, I am not the only one experiencing this grave issue. Many others have reported similar problems on forums like Reddit, which is proof that this is a widespread issue.

Brought vehicle into Dealer for Service due to Check Engine Light being on and Notification of a Malfunction of the I-Stop System. Service Tech indicates that this is a known issue with the Hybrid Battery in these vehicles that could cause the vehicle to unexpectedly stall. This safety issue is significant enough that they would not let us take our car home while we wait for them to obtain a battery, which are currently on backorder. Pursuant to a conversation with a Mazda Customer Experience Representative this has been a known issue since at least January. We have not received any correspondence from Mazda regarding this issue. It would appear that a Bulletin or Recall is warranted for what appears to be a prevalent issue with significant safety impacts.

On multiple occasions the vehicle has falsely detected collisions and suddenly braked while on highway leading to serious safety issues. On other occasions, while changing the lanes with blinkers on, the vehicle suddenly steered back into the original lane and triggered a collision warning even though there was no vehicle/obstacle nearby. This created a serious risk of collision. Even at slow speeds, the vehicle inaccurately triggers a collision warning creating unsafe driving conditions. This frequently happens when we are driving the vehicle in the parking garage, even in absence of moving vehicles nearby. The mild hybrid power train system had issue leading to hybrid system malfunction and iSTOP malfunction. This finally led to hybrid battery failure and the vehicle remaining out of service for over a month. Apple Carplay disconnects erratically creating hazardous condition especially when we are using Carplay for navigation. Such a disconnection requires the driver to suddenly reach over to the phone and input driving directions in the phone again. This is especially dangerous in city driving conditions needing frequent turns.

Hybrid battery failure. Battery issue can cause car to lock up while driving. Dealer service department indicate they have at least 6 vehicles with this same issue. The vehicle has not been inspected by other than the dealership service department that I am aware of. While driving to the dealership for a routine oil change, the car made a quick odd noise then 3 alerts came on said Hybrid system malfunction have vehicle inspected, engine malfunction, system malfunction. Dealer inspected vehicle determined needed a hybrid batter replacement, indicated they could not say vehicle was safe to drive as it could just stop working. Considering they already have a number of cars with same issues in the shop I am concerned this could be a defect problem in many vehicles.

The vehicle displayed "Engine Malfunction have your vehicle inspected" on the dash along with orange lights. The vehicle would drive but without warning would not come up to speed. This caused an unsafe situation entering the interstate where the vehicle was below the minimum speed until we could exit the highway. There was no warning of the low power and inability to operate normally. This was a known problem and the vehicle had all of the recalls already performed. Dealer states there is a problem with the low pressure fuel pump. I am not confident the problem will be solved.

I've noticed ever since the car was new that it had a poor sense of straight ahead especially at freeway speeds. When the lane departure chime was active it would sound constantly{has since been turned off but lighted markers in gauge cluster still fire all the time}. When I take my attention off road for a second to adjust fan speed or temp, the car is close to going into the other lane. Lots of concentration necessary. I've mentioned this to one dealer who checked and adjusted alignment with no improvement and another dealer said they've had other owners of Mazda CX-90's voice the same complaint. There's also a long term test in Motor Trend on a CX-90 that complained about the same issue. I feel there is something wrong here that could be a potential safety problem.

Steering sticks while driving. Then, all of a sudden releases, and this causes a jerk in the steering and vehicle movement in the direction of steering. Vehicle recall 6524A/Jan 18, 2024 for "increase in steering effort" was completed in April 2024. This issue is very apparent at interstate highway cruising speeds to just maintain staying in traffic lane. Worried that steering may continue sticking and not be able to maneuver vehicle to drive safely avoid an accident. Turned off the vehicle lane assist feature to diagnose the issue, the issue still exists with the lane assist feature turned off.

The wires under the hood were chewed up by rodents. The cars wires are insulated with a soy based wiring coating. My car is at the dealership for repair and deemed undrivable. This is so unfair because the car is new and only has 6200 miles on it. I am now facing insurance deductible. The dealer says the vehicle is undrivable because it is a safety issue and the engine might catch fire

Bought this brand new CX90 Premium in October 2024! As of today Feb 11, the car has been in the dealership 4 x fir the same issue!! Dead battery after sitting for 2 weeks! They have replace one small battery and that worked for a month! Took it in last week for the same issue! Dead battery! We find that this is a very coming problem. They said they would now replace the 58 volt battery but it is on back order for 8 weeks. In the mean time I’m paying on this car and I have to drive a loaner which isn’t even close to my car! I’m finding out by talking to other customers this is a common problem! We didn’t get any notice or call! I am demanding this be considered “lemon law” as this is the fourth time it has been in for the same problem. I want all my money back that I paid and demand Mazda USA issue recalls for this issue. It is definitely a big safety issue! The dealer seems to be trying but they are frustrated as well! They are Olympia Mazda in Olympia, Wash, service manager is James Ellis Please respond!

I opened the rear lift gate. I turned around to grab a bag of vegetables. I leaned in to put them in the back of the car... The lift gate hit my head and continued closing pushing down on my head. I was finally able to twist out from under it and it closed all the way. I did not hear any warning beeps. My head and neck are sore. I worry this could kill someone.

When the gear shift is bumped it can go from Drive to Neutral by accident and without the driver's knowledge. I would assume this button needs to be depressed to change gears but on this car it will go from Drive to Neutral without depressing this side button.

The fuel gauge and range indicator are faulty. I was doing long-distance highway driving during the holidays. At 1/4 tank, the range indicator said 110 miles until empty. As soon as the needle dipped a fraction below 1/4 tank (about 20 miles later) the range indicator dropped instantly to 40 miles left AND THEN DROPPED ONE MILE PER SECOND UNTIL IT REGISTERED ZERO. The needle also fell at the same rate until I was driving on the interstate with zero range and a gas gauge buried below empty. All of this occurred within one minute. I pulled into the nearest gas station and filled up with 12.71 gallons (it's an 18.5 gallon tank). So I actually had 5.79 gallons left (or 156.33 miles of range at 27mpg on the highway). Not being able to rely on the gas gauge/range indicator is a safety issue.

I am concerned about a serious safety issue with my CX-90. Both of the rear doors have consistently malfunctioned, failing to latch properly when closed. The door handles get stuck and do not fully return to their original position, preventing the doors from locking securely. As a result, the doors have swung open while the vehicle was in motion, putting passengers, especially children in the back, at significant risk. This is a critical safety concern that needs immediate attention. This issue goes back mid November 2024.
