2016 Mazda 3 with only 21,990 kms or 13,663 miles and I needed all 4 brakes done by Dealer that we leased vehicle through in order to get it certified, as we were buying it off its lease. I told them I wanted all the parts and I will get them checked by another technician as I have never seen a vehicle with such low usage need all the brakes done.

I have sent complaint directly to Mazda Canada and I urge people thinking about purchasing a Mazda to get something else.

This is ridiculous and I will never buy a Mazda again.

Went to Mazda for a new battery under warranty - at under 2 years of ownership the battery was about to die. 1.5 hours later I left with paperwork that said I needed new rear break pads at 30,000 miles. I took the car to an independent shop to verify the breaks would need to be replaced. The independent shop said the break wear they saw indicated a caliper hardware problem and suggested I take it to Mazda for warranty work. I took it to a different Mazda dealership and they looked at the break pads and found "nothing abnormal" and told me it is common for Mazda owners to come in for new breaks anywhere between 20,000 and 60,000 miles. I left frustrated and took it to a second independent shop to verify the findings of the first independent shop. The second place went into more detail than the first shop and said the left rear breaks were at 60% of life, the right rear inner pad is at 30% of life, and the right rear outer pad is at 60% of life. They wrote "suspect caliper sticking issue - rec go to dealer for warranty repair of rear calipers". I sent everything (from both Mazda dealers and both the independent shops) to Mazda Corporate and was told the opinion of the independent shops did not matter and since both the Mazda dealerships found no abnormal wear the issue was closed. Mazda refused to take ownership that this was a warranty issue.

At this time I have not had the break pads replaced. The second independent shop, which just happens to be within walking distance of work, said they would watch it for me to give me more time to deal with Mazda. He said right now there is not a safety issue but at every oil change the break pads should be inspected.

At about 25K the car would vibrate when I applied brake at low, medium, and especially high speeds. I didn't think it was time to have any brake troubles or excessive wear, but since it is a first tell tell sign of brake problems, I took it in to investigate. I had less than 15% left on all four brake pads. All had to be replaced. This is highly annoying as the mechanics also said that Mazda is known for early brake wear and generally new car brakes would expect to go up to 30-40 K before needing complete replacement. I trust their judgement, since that's what they do for living. I was also shown worn parts, so this was definitely a legitimate concern.

Car started to make occasional grinding noise last week from rear passenger. Sounded like something was locked up then freed up. Took it to dealer today and by pure chance it turns out there is a safety recall for rear brake caliper protective boot and possible rusting leading to the caliper being locked up.

Part 573 Safety Recall Report 17V-393

The problem is after 27K they want to charge $500 or so to replace the brakes and rotors which are scored. They refuse to acknowledge that the caliper lock up was the cause of the rotor being scored. The two things together seem really fishy to me. The front brakes are only half worn.

The grinding noise came out of nowhere, no other squeaking or squealing that usually indicates brake time.

I think others on here are victims of the same problem, but reported the issue before the recall which started mid 2017. I got mine today a full 8 months later.
