Water leaking inside near the right/passenger's side D-pillar. Water damage/staining on liner and continually expanding toward the C-pillar. Mazda dealership said it is coming from the panoramic sunroof and the only solution is to install a new sunroof ($4k). Started leaking around 40k miles. QUES: What component or system failed or malfunctioned, and is it available for inspection upon request? ANS: Sunroof (allegedly) and it is available upon request. QUES: How was your safety or the safety of others put at risk? ANS: Mold & air quality QUES: Has the problem been reproduced or confirmed by a dealer or independent service center? ANS: Confirmed by Mazda dealership, and is occurring with other 2023 CX-50's (online forums, reddit, facebook) QUES: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ANS: No, only the Mazda dealership's service techs QUES: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? ANS: No warning lamps or messages. Symptom of weird smell started prior to visible water damage, however, I didn't notice the water damage until the stain was visible enough to catch my attention. I'm not often visually inspecting that area, so I presume it had start long before the major staining started.

What 2023 Mazda CX-50 owners say
Most recent owner complaints, unedited.
My wife did a u turn to turn around in a parking lot and the left front axle snapped pulling back onto a very busy road and almost got hit by two other vehicles. Nothing has been confirmed by a dealer or inspected by a dealership yet since it just happened this evening on October 25th 2026. No warning lamps, messages or symptoms prior to the failure.
Fuel gauge permanently stuck on empty. Computer code = P0463 Occurred on Jan 30, 2026. Mechanic provided error code at that time. Unsafe driving conditions where distance-to-empty calculations are disabled, standard fuel level indicator showing empty (or stuck on full) risking an unexpected engine stall on public highways and roads. I have NO idea how much Fuel is in the tank nor how many miles are left on tank which could lead to unexpected and sudden stops in high traffic situations. Yes: code was confirmed by Advanced Auto, London Motorworks, and personal computer. Fuel sensor stuck on "FULL" in May 18 then again stuck on empty since May 21. Vehicle inspected by mechanic on Jan 30, 2026 Engine Warning light began on Jan 30, 2026 at 9:22amCT
Premature brake wear exacerbated by heavy stop and go traffic conditions.
On multiple occasions the vehicle has not acceleratedfrom a stop while pushing the accelerator pedal. Have noticed this is usually on warmer days, with AC on half to full, within 3 minutes, and within 1 mile from leaving work for the day after car has sat parked. I am worried this will get worse and cause a potentially dangerous situation when turning left against traffic and the car doesn't accelerate.
While driving 72mph on the interstate at 6am on 7/21/26 the sunroof exploded. No foreign objects made impact with the vehicle and there was no sudden temperature shifts. The glass had no previous defects and it shattered into tiny pieces, failing into the car. The sun shade was open at the time. The vehicle is being serviced at a glass repair shop who noted this is a common issue with Mazda sunroofs.
My rear differential is going out at only 40,000 miles. Ive heard from many other people that this is a widespread issue, and i feel requires a response from the company.
Rear differential failure, and side seat tear on 2023 Mazda cx 50
The temperature control dial on the climate control system behaves erratically and inconsistently. When turning the dial to increase temperature, the displayed temperature sometimes decreases. When turning it to decrease, it sometimes increases. The dial also jumps multiple units rather than incrementing one degree at a time. The behavior is unpredictable and occurs regardless of whether the engine is warm or cold. This issue has been confirmed by multiple other 2023 CX-50 owners in owner forums, suggesting a manufacturing defect in the encoder mechanism for the temperature control knob. The dealer confirmed the bumper-to-bumper warranty has expired but has not offered a resolution.
When adjusting the temperature in the car with the dial, it does not respond correctly. It either jumps up or down by multiple degrees. This causes to take your eyes off the road to try to adjust the temperature. No warning lights came on and pushing lighter or harder on the dial does NOT fix it. Only driver side is currently having this issue.
