I recently came to see mazda with my car key not working to unlock the vehicle and most importantly; my steering shaking while applying brakes on the highway. They neither fix the steering nor changed the battery of my key. While i was about to pay the bill; they said the vehicle is fine and i havent addressed the key issues before though i did twice. This had happen to me so many times here and seriously disappointed this time as my steering control has gone worst day by day and takes me so long to unlock my vehicle. I regret i came to essendon mazda. This has been a serious issues on me as i mostly travel on highways. They dont even have a facility of giving hire car at all for customers who come to service their vehicle frequently. Thanks for your time and effort but never going to be back again
