Notes: The 2007 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems.

Owners report problems with the 2007 CX-7's Variable Valve Timing (VVT) & timing chain failing, causing major damage to the engine — Mazda uses an interference design so typically the valves are bent & the entire engine needs to be replaced. Mazda dealers typically quote $9,000 for an engine replacement.

There is also a trend of the turbo failing at low mileage.

Finally for the 2007 CX-7 there is a clear pattern of A/C compressor failure at relatively low mileage. Owners report smoke & occasionally the serpentine belt catches fire when the A/C compressor clutch seizes while driving. Mazda extended the A/C warranty to 60,000 miles, however many owners report their A/C compressor failed very soon after the 60k mark.

In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering turbocharger oil leaks & excessive timing chain noise — an early sign of timing chain failure. However coverage under the program requires perfect documentation of all required maintenance with other stipulations. Buyer beware.

Purchased used in January of 2014. Noticed red plastic housing for brake lights melting above actual lightbulb. Brake lights now shine clear/white on top (where melted), instead of just red. Searched online and found several similar complaints. Checked other Mazda Cx-7's and can see they all have the same issue. I replaced lightbulbs to make sure they match manufactures requirements, they were correct and had melted plastic all over the bulb. Took to local mechanic who said it's probably a wiring issue. Took it to Mazda dealership, they said there was nothing they could do and had never heard of this issue before. I asked them to contact Mazda to see if they would replace light assemblies with unmelted units, they claimed they were told that Mazda would not replace.

Exterior headlight assembly gets cracked due to poor construction and whole assembly requires replacing in lieu of simply replacing the headlamp. This is quite pricey at approx $700 each for both driver's side and passenger side respectively.

I pulled from my driveway onto a highway decided to turn on headlights because of heavy tree cover coming up, it was almost full dark turned knob on lever no lights hit breaks thank god those were still where I remembered them hit fog lights they came on. Went to high beam fogs shut off (correct) high beams at least worked much to other drivers slowing swerving an just all an all pissed off. My high beams seem to turn the clock back to about mid day. Scared the hell out of me though an cost me a shift so I'm into this off the get go 735.00$ lets see how much more its going to cost. So much for giving this rig for my 16yearold in two months should have stayed with Chevy or Nissan.

I was driving down the road at night and headlight on passenger side went out due to condensation see sb-09-003-13 Mazda is fully aware of this issue and refuse to do anything about it. I ordered oem parts at a cost of $1400 from Mazda and had them installed at certified body shop and within two weeks light blew out again, had to replace just the bulb this time, they said they couldn't cover this cost because a Mazda dealer didn't install light. Mazda said the only way they would do anything is if there was a safety recall. What does a recall consist of when you are driving down the road at night and both headlights go out at the same time and have an accident or hit someone else head on causing fatalities. This is about as unsafe as anything I can think of. Again I reference sb-09-003-13. I hate to know there might be fatalities with this problem and everyone ignores it. I told Mazda I would do everything in my power to try and make them responsible for this defect, I guess they have no concern for human life, this is why I am filing this complaint. Just think of all the lawsuits that will happen and the monetary cost involved when this does happen and I think it will since it has already happened once, also lose of life, I don't think there is a price to put on this. Thank you for your time.

2007 Mazda Cx-7. consumer experienced several problems with vehicle the consumer stated shortly after she purchased the vehicle, she noticed the headlights pointing toward the ground and it took 3-5 trips to the dealer before it was properly fixed.

Algae forms between the rear taillight clear lens and moulded gray inner housing. Because the 2 pieces are glued together a person cannot get to the algae to clean it. The algae forms where there is missing adhesive to bond the 2 pieces together.
