2019 MAZDA CX-9 Consumer Reviews

Bought this used from a dealer as a certified used car from a lease turn in. Great condition and low miles for the year. Runs great and I love the way it handles. The trunk space is a little small if using the third row seating, but that’s to be expected.

All service done at the dealership. Most hiway miles.. taken care of. All work. Plus sunroof. Always clear. We'll taken care of when it come to maintenance service required by Mazda manufacturer. On point with service.

I loved my CX-9 Signature until the engine failed at 95k miles. I maintained this car by the book up until it overheated out of nowhere. After spending one minute doing a Google search, I discovered cracked cylinder heads are a feature of many Mazda's late models. Even though there is a Technical Service Bulletin and this is a fairly widespread issue, Mazda will not cover the cost of repair. Expect to pay about $8k for a new engine. Other than that, the car was wonderful. This was my 3rd Mazda and last.

Performs great, comfortable both day-to-day and for road trips. No issues thus far, purchased new but good value for the price (these days anyway). Zero regrets.

We love this suv and when we brought it home are kids loved it just as much if not more i will NEVER Own anything but this Top of the line cant go wrong

Even at 90k miles, our CX9 drove as well as the day we bought it. Only maintenance included oil, filters, rotations, spark plugs, and brakes. Performance was always plentiful and handling was great compared to competitors.

I am a Mechanical Engineer with 40 years of experience in automotive manufacturing (GM, Ford, Nissan, Toyota, BMW, and various suppliers). I am also one of the 100's of owners of the 2016-2023 CX-9 that has experienced the 2.5 Liter cracked engine cylinder head with coolant leaking out of the engine. (I'm convinced there more engines with this issue but the crack is just leaking internally while it continues to grow and will someday experience the external coolant leak.) In my opinion, these engines are ticking time bombs for this problem. All CX-9's from 2016-2023 have experienced this issue. Many engines had to be replaced by Mazda under warranty because they didn't even make it to the 60,000 mile mark before the leak was big enough to cause engine failure. If you're buying a used version of this car, you may already be on your second engine. The replacement parts have also been known to fail eventually. They don't think it's enough of a problem to improve their design. The 2.5 liter engine is also in the CX-5 and Mazda6 and believe it or not, those cars experience the same crack. The turbo charged version of the engine in the CX-9 apparently fails more often than the non-turbo versions because the added weight to the engine increases the stress at the exhaust manifold where the crack occurs. Over 40+ years of driving and working on cars, I've driven many vehicles over 200,000 miles and have never experienced a cracked engine. We bought our CX-9 GT AWD with 112,00 miles and within three weeks, it wasn't running right and then started leaking coolant from the rear of the engine. I was already aware of the issue but had falsely believed cars that made it to 80,000 miles without cracking were probably going to be ok. Now I know better. Mazda has issued a TSB (technical service bulletin - not a recall) for this issue (in 2021) and hides behind their 60,000 mile/5 year warranty stating repeatedly that a TSB is NOT a recall. For cars beyond the warranty, Mazda quotes you $8,500 to $10,000 for the fix. (Easier for Mazda to replace the engine than have to rebuild it with a new head while a customer is waiting to get their car running again. Those engines can then be rebuilt and used in other failed engine swaps.) Independent auto mechanic's should be able to replace the cylinder head with Mazda OEM parts for about half the Stealership's price. (And still make a profit.) Cause of the issue as identified in Mazda's TSB basically points to a weak design and/or parts that weren't manufactured right as if that makes it someone else's fault, and nothing Mazda can fix. Seriously!? I was excited about saving a little gas money with this engine because of the improved economy (over the 2011 CX-9 it replaced). The cost of this repair just took wiped out that plan! Coulda' got a Nissan Armada for less overall cost! What I find amusing is the extended warranty Mazda issued for the 2016-2017 CX-9's with "CRACKS" in the Infotainment screen (they will replace it at no charge), but refuses to acknowledge any responsibility for the "CRACK" in the engine on the same model! "Hey Mazda - The Customer is ALWAYS right." You are going to lose a lot of customers over this before you figure out how this works... Mazda has lost me as a customer and my new hobby is spreading the word so others will think twice about falling for the "Zoom Zoom" line.

This CX-9 has been fabulous, lots of power, no mechanical problems, just regular maintenance. This by far my favorite car to drive other than my motorcycles.
