CarComplaints.com Seal Of Avoid Like The Plague

CarComplaints.com Notes: The 2008 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems, continuing these defect trends from the 2007 model year.

Owners report problems with the 2008 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 2008 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.

This car is a total lemon. You only have to read the feedback on this piece of junk to see it had turbo issues. I took my Mazda with a 7 year extended Warranty, purchased brand new, to their repair centre for every service. The following year my turbo completely died. When I tried to call Mazda with the issue, they co-incidentally could not fit my car in for repair for 2 weeks and of course, the car could not be driven. I had my husband's mechanic take a look and he quoted AU 5,700 to replace the turbo with a re-conditioned turbo. He indicated this had been a progressive issue that should have been picked up a number of years ago. The oil was black and didn't look lilke it had been changed in years - I saw this myself. Clearly another story of Mazda shortchanging and trying to hoodwink their customers. When I called the customer service centre in Australia, I left a message for the case manager to return my call. After more than 15 calls over the next few months, I finally got in touch with.... Adrian. The poorest excuse for a manager I might add. He was too lazy to pick up the phone to the return the call, was rude, defensive and completely contradictory. Clearly he just didn't know his stuff. He indicated Mazda's don't have a turbo problem when I quizzed him, but then in the next breath, indicated the oil gets clogged in the turbo leading to failure which happens with the CX7. But.....Adrian......there's no problem with the turbo, Adrian!!!!!!! You have a very short memory Adrian!!! Clearly Mazda have taken no accountability for this absolutely appalling defect and had they been a reputable and ethical organization, perhaps they may have done the right thing by customers and recalled the piece of crap. Incidentally Mazda, I would strongly suggest that you consider employing people that have that white and grey stuff between their ears.

Our turbo charger went out, not even a year after we bought it used. It was in 6 months of driving it off of the lot. Extended warranty paid to fix it, but it was like pulling teeth for the covered parts, then we had to pay for the bolts??????!!!! thought bolts were needed for all parts to be replaced.

CX-7 Sport 2.3L 4

Had to fight Mazda USA to replace the turbocharger. The didn't even believe their own dealership that the turbo was the problem. Dealer had to send pictures of tailpipe smoke before they covered the problem under warranty.
