NHTSA Complaint #11579338 — 2018 MAZDA CX-5

Head cracked at just under 49,000. Oil dripping on exhaust entering cabin continuously. This issue was identified by Mazda to dealers in 2021 via Mazda TSB SA-031/21. Despite having our vehicle serviced multiple times at the Puyallup Mazda dealership after that date, no mention was made of this noted defect. We drove for about a month inhaling the petroleum fumes often thinking it was from trucks ahead of us on road. Dealership replaced the head assembly but since car was 4 months out of warranty (we are the original owners having purchased it new from this dealership) the dealership insisted on charging us for repairs. We've been breathing fumes from a known issue and others may be as well due to faulty manufacturing the manufacturer and dealer refuse to take full responsibility for.what is clearly a defect.
