I bought my CX7 Nov 2010 with 22583 miles and now I have around 40500 miles on it. last week it wouldn't accelerate and made alot of knocking noises. Took the car to the local dealership, they told me the motor needs to be replaced due to sludge. the car is still under the power train warranty, however, after providing adequate oil change receipts, they have denied my claim for the warranty. i have made several calls and sent emails, they simply do not care about the consumers. Of the total miles, I wasnt even the owner of the majority of them, why should I be responsible for someone else's failure to take care of the car.....I have my proof! DO NOT BUY FROM MAZDA!!

When you buy a used vehicle you assume, by default, the previous owner's "responsibility".
 
Not excusing Mazda building junk but "buyer beware".

It is really frustrating to see these emails and they all say the same thing. At the very least, Mazda could send out a notice about the type of oil to use and how often it needs to be changed. But that would be admitting fault, wouldn't it?
I just got my car back (after 8 weeks and one new engine) and they say every 3,500 miles change the oil and use synthetic oil.
Guess what, after paying the car down for the next year, it's going on the block to sell!

I think your comment is interesting. You are correct to some degree, but let's face it here.... These aren't typical situations for used vehicles. I have always purchased used, and NEVER in my life dealt with a breed of car as Mazda. I just dumped mine, thank God. Mazda should be held responsible for selling crap, just like any of us would be held responsible in our own lives. Your comment about "buyer beware" doesn't have a leg to stand on in this conversation forum.

Not to defend Mazda-but why are you attacking wwest? Depending on the price point, the state where purchased, and from whom... used cars are "buyer beware." no warranty for the most part. Assuming that the present owner has taken meticulous care of the Mazda cx-7.... how do you know that previous owner didn't run it low on oil or coolant?--(even once) and for the cx-7-- that is more serious than the average car because of the turbo implications.
 
I'know from experience with these cars because I myself am driving a 2007 cx-7 w/ 80,000 miles . Timing chain replaced at 55,000 miles --EGR valve and fuel pump replaced at 70,000 miles. I think all the newer vehicles are failing parts with more frequency due to to manufacturers making the vehicles (and their internal parts) lighter and lighter due to stricter pollution and gas mileage requirements.

#319 of 578 2007 CX-7 Engine Failure by flig_chris

Dec 23, 2011 (11:37 am)

Another CX-7 Engine Failure. The following was submitted to the NHTSA.
 
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 the dealership 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.

#320 of 578 reliability issues with earlier years, better for 2011? by biochemist

Hi, I'm in the market for a CX-7 but all these posts are making me wary of purchasing the vehicle. Has the reliability gotten better over the years since 2007 or pretty much the engine and powertrain has stayed same over the years and I will likely encounter the same problems several years down the line? Thanks in advance.

First off,,,we absolutely loved our 2007 CX-7. Had a relatively minor issue with the timing chain and it was repaired under warranty at about 21000 miles. However, I also became concerned after reading this forum and others and soon thereafter, traded in the CX7. It is my understanding that this timing chain issue and others are 2007 problems. Good luck...it is a nice car.
