Dealership maintained Cx-7 experienced major failure while driving. Engine died and major oil leak was noticed. Car had to be towed to the dealership. The dealership first indicated that there was some type of failure regarding the #3 cylinder. Dealership said that the probable cause of failure was due to turbo overheating. Later the dealership stated that the #4 piston failed and caused catastrophic damage to the engine. The cause of failure was never determined. The engine, turbocharger, thermostat, egr valve, intake manifold, starter and O2 sensor were replaced. Total cost of repairs (labor, parts, and misc charges) prior to tax was $10,557. 49. Prior to engine failure we informed the dealership that the check engine light was constantly on but stated that it was due to the gas cap not being properly put on. They never scanned the computer despite the car being under warranty. Additionally a ticking noise has been previously brought to the dealership's attention but was told that the engine noise was normal for this particular engine.
The ac compressor on the vehicle seized causing smoke and sparks to come off of the belt. The ac compressor and the belt both need to be replaced.
After driving down the expressway the air conditioner stopped working. I brought it to the mechanic and was told the air compressor kit went out and it is $2,300 to fix.
Bought my 2007 Mazda cx7 with 76000 miles not even kidding but 12hrs later my motor mount and the vvt went out. A month later radiator cracked and now it had a bad oil leak and loud knockin noise it sounds like an old truck very bumbed out I have only had it for five months.
(March/2011) light came on around 65k miles. Took it into dealership and they said oil was low and yvt needed replacing. Cost was around 2500. No reason why oil was low and last changed by Mazda less than 7500 miles before. Also full service was done at that time. (June/2011)while on highway at high speeds the car lost acceleration, emittied high pitch whirring. And became difficult to control. Towed to dealership and it is being blamed on bad turbo. No reasoning behind failure other than saying oil change issues. The problem is that Mazda is the only entity that has ever worked on this car at least twice per year for check ups. There also appears to be others with same reported problems to both turbo and yvt.
Another driver turned in front of me, failing to yield the right-of-way. I was doing the speed limit (45 mph) upon entering the intersection. When my Cx-7 made contact with the passenger side of her minivan, none of my airbags ever deployed. My shoulder, neck and hip (I still need surgery on all 3 areas) were injured in this accident.
Timing valve replaced at 34,951 miles, then engine replaced at 41,060 miles on July 24, 2008.
