Replying to: phillauer (Mar 28, 2009 4:15 am) Tow car to dealer, think I am replacing a belt get phone call telling me compressor locked up and snapped belt....now it makes sense.... did some digging and found out design change on the following year, so that basically proves Mazda is aware they have a major problem... the more of us complain the more likely for a recall and thus justice as I paid out 1400.00 ..... My car has 39K just passed thru warranty in March 2009. Otherwise I love the vehicle, only other problem I have had is the white smoke about once every six months which the dealer tells me they have never seen.... I will be filling out the NHTSA info tonight... |

If you discover that the above is what is happening and/or is happening to often for your comfort, you can use the max cooling mode (adjust the blower speed manually to control your comfort level) to dramatically increase the A/C system's efficiency and thus avoid the "zone".

Replying to: wwest (Apr 22, 2009 10:22 am) I have experienced the so called "smoke," but that is simply condensation being blown off when humidity is high or the fans are run on low for an extended period of time. That happens in all vehicles under those same circumstances (I've owned GM, VW, Nissan, Ford, BMW) and is a physics issue, not a car issue. Also, all cars cool down much faster in recirc mode. All cars that I've owned struggle with the high temp/high humidity/non-recirc combo. Some better with others but all within a range I'd consider reasonable for that circumstance. For the record I live in the Washington, DC area. Mick |

Replying to: ihatemazda (Apr 14, 2009 10:46 am) I have had my POS CX-7 for 2 years. I bought used, it had only 4900 miles on it. We noticed a/c problems, took it in once and they adjusted, but never really fixed. Then in April of 2008 we were leaking oil and coolant. Turns out had blown seals on the transfer case. How many vehicles blow seals at 5500 miles? That should have been a wake up call then. Now, the wife and I were driving home from the store on 4/8/09 and same thing as you, heard the loud noise and car had to nearly crawl home. Had towed to the dealer on 4/12/09 and was told the very same thing, that turbo was blown, I didn't change my oil and now it needs a new engine. They want $9400.00 plus tax to drop a new engine. Hell with them if they think they are going to any more of my money. I still owe a buttload on the car.

Replying to: mazcrap1 (Apr 22, 2009 6:45 pm) If you happened to have followed the year to year development of this "new" F/awd system, say on the Ford Escape, you will know that early on there was a serious over-heating problem. At one point Ford had a temperature sensor in the system and advised drivers to pull over and let the F/awd system cool down before proceeding. So I'm fairly sure the need to cool the PTO arose out of that issue and I doubt that the overall cooling system capacity was considered before adding the additional cooling load. Add a towing load and REALLY get into trouble, the A/C would likely be disabled continuously. |

Go to Home Depot and purchase a water flow shut-off valve to insert in the water hose to the cabin heater. Close the flow during the summer when the A/C use is predomninatly for cooling and thereby increase the A/C operational efficiency dramatically. Much lower load on the engine cooling radiator with the A/C compressor not cycling on as often. But nothing will make up for ignoring the need for regular oil and filter changes, especially with a turbocharged motor. I would NEVER buy a used car with a turbocharger absent a discussion with the previous owner to make sure that the previous owners wasn't of the "boy-racer", or "like", mentality.

Replying to: wwest (Apr 23, 2009 8:18 am) With that said I am looking for some reassurance and advice: Yesterday (May 10th, 2009) my AC compressor clutch went out on my 2007 touring CX-7 Below I have listed the facts: 1. I am 300 miles over warranty 36,300 2. I had a full (top of the line) inspection at the top mazda dealer in Omaha before the warranty expired less than a month ago 3. The dealership feels bad that this has happened and offered to pay for all labor costs 4. I have to pay parts $1,200 for a new A/C compressor clutch My question are: 1. Should they have foreseen this problem? (I understand not all things are able to be foreseen) 2. Is $1,200 sound right for a new AC clutch? 3. Would I be safe with a used AC clutch? Thanks in advance for the help! CDCAMP UPDATE: my A/C compressor went out at 36,300 miles (300 miles after warranty). Dealership said they would pay for labor because I had a full inspection 3 weeks ago on the vehicle. Below is service sequence of events: Before I go into the summary of conversation I first want to say that all the dealership and Mazda customer service personnel were highly professional and very kind. I too was professional (IMO) and was not trying to flame them but, trying to reach a reasonable solution to the problem: 1. Dealership: Woodhouse Mazda - Omaha 1. They acknowledge that this is one of the main problems on CX-7's 2. They acknowledge that the old A/C unit is faulty (Because the new unit is a redesign) 3. They acknowledge that they do not check this problem as a "preventative maintenance" check (prewarranty) 4. They acknowledge that they have a significant markup on parts ($1,200) so "Free Labor" is just another tool used for customer service 2. Called Mazda customer service 1. They said that they might be able to file a "Post Warranty Claim" 2. While on hold he spoke to the warranty and they said the "district manager" knew the situation and approved "Free Labor" as the best they could do. 3. Mazda (Customer Service) then claimed that was the best they could do. So in conclusion, I am out $1,200 dollars because of a faulty (Poorly designed) A/C compressor. So not only was I on the side of busy highway switching my baby and baby's car seat into my surprisingly reliable BMW 5 series (with 75,000 miles) but, now I have to pay 30% margin on new parts.... But hey the Labor is Free!! Thanks MAZDA!! Be Warned: THIS PART WILL FAIL (Make sure it fails before your warranty is up) CDCAMP |

Replying to: cdcamp (May 11, 2009 12:52 pm) Exactly how would one go about doing that?  But seriously, I'm not sure there's anything you can do at this point except try to talk them into giving you a bigger break on the cost. Even if they had inspected the clutch, anything they might have discovered would likely have been designated as "normal wear." tidester, host SUVs and Smart Shopper |

Replying to: cdcamp (May 11, 2009 12:52 pm) Check with an aftermarket shop and you may get by with lower cost parts AND labor included. Just a quick check with Google indicates automotive A/C clutches sell for ~$100 and compressors for <&400. As the rabbit said as the combine approached "I'm about to be REAPED!"
