2018 MAZDA CX-5 Complaints

Cylinder crack. Recently got a oil change and driving to work couple days after and smelled oil burning into my cab and smoke coming from underneath my hood. Got to work and opened my hood and noticed large amount of oil on belly and leaking oil from my cylinder. I got this vehicle thru a dealership and when contacted, they stated if I pay $7,500 I could get a trade in!!! After numerous searching, I've found a lot of owners with the 2018 Mazda CX-5 are having the same issue with cylinder heads and no corrective actions. Now I have to pay Mazda (after their defective parts) for their mistakes

Ghost Screen, a very well know issue for Mazda. The screen change on its own, no way to fix it. Mazda recalled all their 2014-16 screen, and the 2017-18 are affected by same issue but they are not taking responsibility for it. Dealership wants to replace the screen, that's over $1,000 repair. Please make Mazda earn their mistake.

The radio (aka infotainment system) goes crazy sometimes- changing radio stations, fliipping around to different settings, stations, etc, all on its own- like it's possessed. this causes a distraction to the driver and is unsafe. its also really upsetting for this to happen on a card i've only had 3 years.

This vehicle has stalled out while driving at least 4-5 times since purchasing it in 2018, although issues started about 2020 or 2021. It usually starts with the radio console either malfunctioning or going dead completely while I’m driving and several minutes later (usually after stopping at a red light but sometimes while actively driving) the car stalls out in the middle of traffic. It starts up after few minutes but it’s a very dangerous situation. It also sometimes hesitates when putting my foot on the gas, as if there’s a fuel injection problem. I already got all the recalls fixed but there’s obviously other significant problems with this vehicle. If it causes me to get injured I will be taking legal action.

SRS Airbag light went off and ODB-II reader indicated passenger side supplemental restraint module error. We called Mazda October 20,2023 as the vehicle was nearing end of warranty period for the airbags system (warranty ended October 30, 2023). Mazda stated they could get the vehicle in on November 12, 2023, which is after warranty period and we would be required to pay to fix the car. An online search quickly resulted in seeing many other people with the same model of Mazda having the same issue for the passenger seat. I called national Mazda today, December 15, 2023 and they said that the vehicle is now 45 days out of warranty and no longer their problem.

The contact owns a 2018 Mazda CX-5. The contact stated that the vehicle was taken to the dealer for a scheduled service appointment. During the inspection, the contact was informed that the vehicle had a cracked cylinder and the cylinder head needed to be replaced. The vehicle was not repaired. The contact was informed that the repair would not be covered under the warranty due to the warranty being expired. The manufacturer was made aware of the failure. The failure mileage was approximately 84,000.

Two bolts simultaneously dislodged brake caliper which, in turn, disconnected brake fluid hose resulting in loss in brake responsiveness.

Defective cylinder head resulting in oil leak. Confirmed and inspected by dealer. No warning messages or symptoms. Just smell of burning oil.

I just had my vehicle in for routine maintenance and oil change and three days later it started leaking oil, staining my driveway, with the leak getting progressively worse then my check oil light went on, and the day I brought it in, and it was smoking under the hood. My safety and the safety of others on the road was at risk. At the routine maintenance visit they found no issues with the vehicle. After bringing it into the dealership they diagnosed it as a cylinder head crack needing replacement. We had another dealership look at the diagnostic video and explain that this is poor manufacturing. It’s just over 60,000 miles but is still within our warranty from a timeline aspect. Upon research we found this is happening to many people with a Mazda’s from year, 18 to 21. There are many forums about this. Upon an online search we found this problem documented as tsb SA-031/21. I am disappointed that the Mazda company is aware of the faulty cylinder heads in this vehicle, and now I am responsible for the maintenance charge.

Was driving at low speed and out of nowhere the warning lights came on , smart city , abs, among others. It's caused by this vehicles front facing camera and or front radar emblem malfunctioning causing the vehicle to slow down , low power , and steering wheel jerking making mechanical sounds. There's a tsb as well.
