My daughter with her newborn infant had the vechile stall on them in heavy traffic. The car has 60,000.00 miles and is meticulous maintained. We brought to the dealership and was told it needs a new engine at a cost 9,000.00. I opened a case with mazda corporate case #1-290023-832 and was told that it is an 9 year vechile and they can only offer an employee discount on a new car or 1,5000. This is a safety issue and a manufacturer defective. My daughter and her child could have been injured. Please assist.

Tl* the contact owns a 2007 mazda cx-7. Months after the vehicle was purchased, the instrument cluster gauges flickered and the vehicle stalled. The vehicle was towed to the dealer.

Vehicle stalled in sams club parking lot. It did restart but started making a rubbing or grinding noise. Turns out the AC compressor locked up. According to internet postings it is a known issue with 2007/2008 models. Apparently it was addressed for 2009 model. I've ran 7 or 8 vehicles for 200,000 plus miles and have yet to have a compressor go out until this know anomaly. Where is the resolution from mazda?

December 2012 (at about 64,000 miles) dealer replaced timing chain under extended warranty but didn't do anything to correct intermittent power loss and engine hesitation that I had complained to them at the time. November 2013 (at about 78,000 miles), the car experienced severe loss of power, stalling and heavy white smoke from the tailpipe. Dealer claimed "oil sludge" caused engine and turbo failure and refused to bear any responsibility or cost to fix. Mazda USA also refused, claiming the problems were due to insufficient oil change by the customer. Since we change oil regularly, we don't buy mazda's claims, especially when they just opened up the engine less than a year ago to change the timing chain, and at that time didn't claim there was any "sludge" inside. Seeing many similar customer complaints on the internet, it seems mazda has been trying to hide a serioius design and/or manufacturing flaw by blaming the customers as the cause of it. ?

Vtt timing chain broke on this vehicle which could have resulted in a horrific accident if the car had been mobile. Mazda has acknowledged that this engine component is faulty, because they issued a warranty extension to 72,000 miles in january 2012. This sort of engine failure could lead, and may have already lead to numerous accidents if they vehicle stalls while on the interstate or other roadways. Mazda should recall the engine part and reimburse customers who have had to pay for this mechanical failure.

On may 18th I took my car to the mazda dealer in nj for a timing belt recall and was replaced. On may 28th driving on the highway the A/C stopped working, the warning lights came on and immediately the car stalled. I then had it towed to the same mazda dealer. The next day they told me that my engine was blown and it was going to cost me $7,476.79.I have always serviced my car every 3,000 miles, my car is only 6 years old and only has 57,040 miles. I took it to an engine expert and told me that the engine was defective. Mazda should recall all cx7s from 2007. It is obvious that all of them came out with a defect.

I was heading west out of denver on interstate 70 when my car completely failed and the engine shut off. I was in the left (passing) lane and was fortunately able to pull into the median to avoid a crash at high speeds. My four-month old son was in the back seat so I was shaken and frightened for his safety, and unable to re-start the vehicle. We were stranded there for an hour waiting for a tow-truck with other cars pushing past us at very high speeds. To add insult to injury, this is a known issue for this make and model of mazda. The company does not stand behind their vehicles--instead they are discontinuing the cx-7 b/c of it's poor engineering. They also offered an extended warranty for this issue (up to 70,000 miles so my car is not covered.) if they were a responsible company they should issue a total recall of this vehicle in order to replace the timing chains. Other problems with this car in the short time I had it (bought it at 53,000 and it has a dead engine at only 76,000) -mysterious electrical problems causing all gauges to go haywire when I accelerated or turned -leaking valves in the transmission (just paid $800 to have that repaired in october) -faulty air conditioning compressor (also extended warranty) basically, this car is a total lemon. If you have one that still runs--beware! If I had been 2 miles farther down the freeway I would have had no where to pull over and would have been stalled dead on the freeway in heavy traffic... With young son in the back seat.
