After looking at the picture of the bolt a bit more, I would suggest you have the mechanic check the other similar bolts on you car. The corrosion pattern on that head indicates that a majority of the cross section of the shank of the bolt had been cracked for a while. The crack allowed water...

I would not use a Fumoto valve on a car that goes off road but otherwise it is a pretty low risk if some common sense is applied. In the cases I'm using it, the valve faces backwards and the oil pan would have to take a hit for the valve to be contacted. As far as used oil goes, another option...

A 19mm bolt to hold on plastic panels? Is that the size of the socket that fits on the hex or the overall diameter? A 19mm hex nut is more typical of something that is torqued to a high value (like a drain plug or suspension bolt). If it was near the tire, I'd take a look at the strut at that...

If you are on the fence about DIYing the oil, I'd recommend buying a Fumoto valve (google it) and installing it - this reduces the time screwing around with the drain plug to zero. You can get one with a drain tube that you can guide into the container you are using which reduces the chance of...

I would suggest climbing under the car and looking around. Normally smoke implies that whatever is leaking is landing on the hot exhaust and burning. There is so much oil on that cardboard that it looks like you have a leak at the filter or pump that is then getting blown all over the place as...

The FWD and AWD cars have different fuel tanks. I suspect the all wheel drive fuel tank has a hump in the bottom of the tank to accommodate the drive shaft while the front wheel drive tank has a flat bottom. In Subarus, for example, the tanks are shaped like a "saddle" with low spots on the...

You are correct. 123 are the difficult ones, 456 are staring you in the face when you raise the hood.

Without more information from Mazda it is hard to draw any conclusions from this. The issue appears to occur due to some combination of heat cycles and loading imparted by the weight of the exhaust on the cylinder head while going over bumps. Seeing cars with high mileage without head...

Mazda and Ford were also pretty tight lipped about the water pump issues on the old V6, so the silence is par for the course. It looks like Mazda sold about 120k CX-9s during the 5 year period the TSB references. Doing some back of the envelope math, the average dealer would have sold slightly...

How many do they sell in a week?

Mazda has nailed the "don't own it out of warranty" aspect of the German luxury experience, at least for me. I'll give them a few years to work out the kinks on this one.

As far as the turbo goes, it is 2022, not 1982. Turbochargers routinely outlast the rest of the car these days as long as they are maintained. For instance, I have a 19 year old Subaru with the original turbo that routinely seeds redline, full boost, etc. Further, I do not recall a single...

The TSB applies to every CX-9 made before June 2020. It's a design flaw.

If the check engine light is on because of a camshaft position error and there is no coolant in the reservoir, I am afraid you have experienced the water pump failure where coolant leaks into the crankcase. The coolant mixes with the oil, which caused the variable valve timing actuator to fail...

This site has monthly summaries of new car and used car inventory levels and prices: https://www.coxautoinc.com/learning-center/tag/inventory/ If you read a few articles, they call out brands with the highest and lowest inventory levels. The domestic brands tend to have more inventory and...

There was a summary article in Automotive News: - $10.6 billion dollar investment through 2030 - EV production in North America maybe in 2026-7, depends on how tax credits work out - Battery partnership with Envision AESC Group, a Chinese-owned battery maker - New hybrid system coming - Lots of...

The VVT actuators are driven by engine oil. If the oil is contaminated or low the VVT actuators can start to act up. The code you have can indicate an electrical issue with the cam position sensor or that the ECU is getting odd readings from the cam sensor. If there's nothing wrong with the...

What does the oil look like? When is the last time you changed it?
