NHTSA Complaint #11705720 — 2019 MAZDA CX-5

On 12/10/25, my 2019 CX5 NA had major oil leak after smelling a burning smell for a few days. Took it into local mechanic and he couldn’t find the leak, did an engine wash and additional testing before identifying a crack in the cylinder head; the leak was coming from the exhaust manifold. There was oil all over the engine and the underbelly of the vehicle; according to the mechanic, I was lucky the car didn’t start on fire with the amount of oil. I was informed that this is a common problem with the turbos and the NAs but the extended warranty only included the turbo engines. Contacted Mazda customer experience and set up an appointment. Vehicle went to the Mazda dealership on 12/15 and it was confirmed that there was a crack in the cylinder head and received an estimate of $11,000 needed for repairs. $7000 of that was for a new cylinder head. This was after an independent mechanic inspected my vehicle and stated everything looked good besides the main issue and needing new rear breaks in the next few months. 12/15-contacted Mazda customer experience and and case file was opened. 12/16-contacted customer experience back due to not receiving a call and received the name and extension of the assigned case manager. 12/17- still had not received a call back and left voicemail for case manager. Requested a call back to myself and the dealership; received a call back a few hours later and I was never asked what happened but was informed that Mazda corporate could not help me due to the warranty being expired. I am now required to pay over $250 to the dealership for an inspection of the vehicle I never requested. There were initially no warning signs but then the low oil light came on after 3 days of smelling something burning.
