CarComplaints.com 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.
I have owned this Mazda CX-7 for about 5 years, maybe a little longer and it has been nothing but problem after problem after problem. Each month it is something new, starting in 9/2016 the transmission went out, paid for a new transmission $4k+, had an oil leak that was fixed back to back, check engine light came on for P0204 cylinder 4 injector circuit had it replaced and exactly one year later the check engine light came on again for the same code, power steering pump was replaced... i could go on and on. overall in 2 years i have probably put about $10,000-$14,000 into it and still to this day have issues. WORST CAR EVER!
Check Engine Light came on. Had it checked. Code was for crankshaft position sensor p0016. Had it fixed. A week later check engine light came back on. Same code popped up. Is there a recall for this problem?
