Just crossed over 55k on my 2017, so probably close to where I'd see issues. Coolant level is 1/2" below "low". Hoping it's normal consumption, but I'll top off and assess closely.
Cracked heads are not unusual for first gen programs running higher compression/ PCPs. I wish there were more specific details on the nature of the failure beyond "casting defects" which IMO is a cop out. Based on the warping comments, my money would be on coolant starvation as the primary failure mode.
There just doesn't seem to be a good definition of the coolant consumption spec, unlike what you see with oil. However, given my mileage and proximity to powertrain warranty running out, I decided to make an appointment with the dealer later this week. Though I've been doing my own maintenance for a while, I figured I'd at least get the coolant level issue documented and top up for the nominal fee they charge. With my spate of (bad) luck this month, I would not in the least be surprised if they called it.That's something I'm curious about, normal consumption. I'm not sure if the manual mentions this anywhere, but what amount of consumption would be considered normal?
Did the vehicle seem to be running ok on the way home? Can't think of anything except a fairly massive head gasket issue to explain oil and coolant leaking externally at the same time.... they verified that the engine is leaking oil AND coolant. ...
Could be many things other than a head gasket. My concern would be a poorly assembled engine.Did the vehicle seem to be running ok on the way home? Can't think of anything except a fairly massive head gasket issue to explain oil and coolant leaking externally at the same time.
I was assuming they ran it with the bottom cover off and would have seen leaks caused by loose fittings, before giving it back to the owner. But who knows - maybe that was too much to assume, so yes I suppose other mistakes might be possible.Could be many things other than a head gasket. My concern would be a poorly assembled engine.
Yes, car ran like new. I really enjoyed having it back.Did the vehicle seem to be running ok on the way home? Can't think of anything except a fairly massive head gasket issue to explain oil and coolant leaking externally at the same time.
You are certainly having a brutal experience, and I'll tip my hat to you for retaining your composure and not running around with your hair on fire over this. Not very many folks would be able to write this report as calmly as you did
Sorry to hear this. I got mine back after 3 and a 1/2 months and it was done perfectly. I guess its an issue with the new engine or the level of competency of the technician. Hope you get it back soon. I am still amazed at how great a vehicle the CX9 is......if you are more into style, performance, ride, build quality and even luxury. I wish it had come with a normally aspirated v6 like the Acura mdx which i seriously considered trading my cx9 on.... but then i read complaints about it being anemic at low rpms and a 10 speed transmission? And lacking a luxury vibe annnnd 53 to 57 grand to purchase...not going to do it......Mazdas torque and power early in the rpms is actually smart even with the dropoff at 5,000 rpm. I love the low end grunt this thing has...hopefully, the engine replacements that are happening with revision have cured the problem. I will find out or possibly buy the straight six cx9 if they make one!Yes, car ran like new. I really enjoyed having it back.
I'm driving a loaner, so I can't really complain. Yelling at service guy won't really help with anything. It's frustrating, but it is what it is.
The new engine is leaking somewhere in the back. They thought it could be a damaged oil pan - they put a new oil pan, but that didn't solve the problem. They're ordering a new engine from Mazda.
I’ve been in touch with corporate once before. They weren’t very helpful either at the time. Their solution for my misfiring was to offer me employee pricing to buy a new Mazda.There's definitely a leak somewhere. Press them with an explanation because a 40k mile engine shouldn't leak anything. If they give you the run around, contact corporate. Good luck.
