Mazda CX-7

The Mazda CX-7 sports crossover was announced at the beginning of 2006 at the Los Angeles Auto Show. First of all, the novelty was intended for the North American market. The CX-7 reached Europe in a year and a half. European versions stand out by the presence of repeaters in side mirrors, a protective skirt under the front bumper, a route computer and leather upholstery of the top of the interior of the doors. In 2010, the exterior and interior of the crossover were slightly “retouched”.

Engines

Most of the Mazda CX-7 was equipped with a 4-cylinder 2.3-liter MZR turbo engine, which was also used on the charged versions of the Mazda 3 MPS and Mazda 6 MPS. The European engine has a capacity of 260 hp and is tuned to 98th gasoline. For the Russian and American market, the engine was deforested to 238 and 244 hp, respectively, under the 95th gasoline. In 2011, a modification of the CX-7 appeared with a 2.5-liter atmospheric recoil of 163 liters. with. Diesel versions with 2. 2 / 173 hp. officially in Russia were not offered and in the secondary market are almost not found. The gas distribution mechanism with a chain drive of a 2.3-liter turbocharged engine presented many surprises. After 60-100 thousand km of run at launch could appear short-term "crack" for 2-3 seconds. This sound is a harbinger of the impending “trouble”, signaling the need to replace the actuator (also known as a phase rotator, aka the VVT coupling). The reason is the wear of the pin hole of the phase rotor lock. Due to insufficient heat treatment (quenching) of the metal, the hole broke, and the pin ceased to be completely removed. This led to a shift in the phases of gas distribution. Further operation of the engine contributed to the stretching of the chain, an even greater phase shift and the appearance of "diesel". The stretched chain began to rattle, touching the head cover of the cylinder block. The engine was not generally much lost in traction, and the Check rarely caught fire, so owners often paid no attention to the symptoms. Fuel consumption increased, sometimes significantly.

Transmission

The 6-speed manual transmission was only available on the European versions of the Mazda CX-7. There are few such copies in Russia.

The 6-speed “automatic” is the only option for a turbo engine. the 2.5-liter atmospheric was combined with a 5-band automatic transmission.

Serious problems with the 6-speed automatic TF-81SC Aisin usually do not occur. With age, solenoids can fail.

In the case of the 5-speed FNR5 box of Mazda’s own design, with large runs, there are episodes with wear of the planetary gearbox (about 23,000 rubles with work).

On the restyled CX-7 from the cooling circuit of the automatic transmission oil was excluded thermovalve. In severe frosts, this led to thickening (freezing) of oil in the cooling circuit, the break of the hose and complete "dehydration" of the box. After eliminating the “leakage” and filling with oil, the box’s performance was restored.

When running more than 80-100 thousand km, the glands of the transfer case and the rear gearbox began to “snot”. The reason for "fogging" of the dispenser can also be the "drying" of the sealant, between the halves of the body. For the elimination of leaks will have to pay about 20 000 rubles.

There are also cases of repair of the transfer case due to wear of bearings and gears.

After 120-180 thousand km, sometimes you have to face wear of the slits in the connection of the automatic transmission differential cup-intermediate shaft. For new details will have to pay about 30 000 rubles.

Walking

Front shock racks can be knocked after 80-130 thousand km (3-12 thousand rubles). By the same time, the supports of the front shock absorber are also handed over. The cost of one support is about 2-3 thousand rubles.

Ball supports and silent blocks of the front levers wear out after 100-150 thousand km of run. Ballroom changes in the lever collection - 21 000 rubles for the original or 4-13 thousand rubles for an analogue.

A little later comes the turn of the Silentblocks of the rear suspension. A set of rubber and metal parts will cost 6-9 thousand rubles. For work will be asked more than 3000 rubles.

The rear stage bearings could "buzz" through 50-90 thousand km. The cost of the original bearing, going in the collection with a hub, about 12 000 rubles. The analogue will cost less – 5000 rubles.

In severe frosts in winter, hydropower hoses often ripped off. The staff clamps could not withstand the increased pressure of the thickened liquid. The Mazda CX-7s assembled after October 1, 2010, were modified to have the clamps and the length of the cooling pipe reduced to reduce pressure. On previously released cars, dealers replaced the cooling pipeline and 3 reverse hoses.

The front brake discs often overheat, which leads to their "deformation" and the appearance of vibration when braking. Many had to change them after 25-30 thousand km of operation. The same goes for the front brake pads. Especially "lean" reached on the original drives up to 120-150 thousand km. A pair of new front brake discs will cost 6-9 thousand rubles. The rear brake pads reach 100 - 130 thousand km.

Typical problems and malfunctions

The chrome details of the body finish and “badges” can darken or “buzz” over time.

Owners of the restyled CX-7 faced cracking of the mirror element after turning on the heating of the side mirrors.

The Mazda CX-7 headlights are often foggy, especially with xenon lamps. Some dealers on warranty machines make replacement of headlights.

The taillights also differed, inside of which the bulb (basket) was melted from the heating of the lamp. The cost of a new lantern is about 11 000 rubles. To avoid this problem on a still-wide flashlight, many people changed a conventional lamp to a cooler LED. Later, Mazda announced a recall to replace damaged optics.

Salon Mazda CX-7, despite the fact that it is replete with hard plastic, is not prone to creaking. The most common places of appearance of "crackers" - the front panel, more often in the area of ducts, the front doors and the back latch of the rear seats. Many note the appearance of a “click” during the warm-up of the cabin in the cold season.

When running more than 100-150 thousand km can fail air conditioning compressor. The reason is jamming of the pulley bearing or failure of the electromagnetic clutch. After 200-250 thousand km, the compressor itself can be swayed.

The CD changer often stopped accepting or returning discs. Dealers in such cases made the replacement of the “head” of the audio system.

• The reason is the wear of the pin hole of the phase rotor lock.

• km turbo engine could go for major repairs due to the late piston rings, the destruction of the rings or premature wear and twisting of the crankshaft rod liners.
• The problem with the crankshaft inserts is more common.

The expense of a crossover with a sporty character, it is quite suitable for temperament. In the city it will be about 18-20 liters per hundred, calmer drivers it is more modest - 15-18 liters. On the track at an average speed of 100-110 km / h, the flow rate will be about 11-12 liters.

Given a number of disadvantages of the turbocharged engine, in everyday operation, the restyled Mazda CX-7 with an atmospheric gasoline engine of 2.5 liters is preferred. However, you will have to take into account the lack of all-wheel drive.

• Engines: The reason is the wear of the pin hole of the phase rotor lock.

Shows, bargaining and re-registration take time: buyers look, promise to think and disappear. Fair price after inspection closes the auction on the spot. If money is needed urgently, the purchase takes away waiting and repeat displays.
