Replying to: interested_72 (Sep 19, 2009 1:06 pm) Give me your email address and I'll send you the pages from the CX-7 service manual. Unless you drive it under extreme conditions or tow equipment with it, the 7500 miles is Service. Here are the excerpts from the owners manual. Follow Schedule 1 if the vehicle is operated mainly where none of the following conditions apply. l Repeated short-distance driving l Driving in dusty conditions l Driving with extended use of brakes l Driving in areas where salt or other corrosive materials are used l Driving on rough or muddy roads l Extended periods of idling or low-speed operation l Driving for long periods in cold temperatures or extremely humid climates l Driving in extremely hot conditions l Driving in mountainous conditions continually If any do apply, follow Schedule 2 (Canada and Puerto Rico residents follow Schedule 2). For schedule 1, the oil should be changed every 7,500 miles. If you have truly only had the car a few months, you probably fall under the lemon law. Check the lemon law in Florida. http://floridadrivers.com/traffic_court/florida_lemon_law.php/ or http://autolemonlaws.com/florida/index.htm

Replying to: interested_72 (Sep 18, 2009 3:05 pm) It just dawned on me that it sounds like your car has a known problem that is addressed in the Mazda TSB 01-002/08. Noisy VVT Actuator Read this description and TSB below. The problem is just noise, not a bad engine (most likely). If this Mazda service dept refuses to review all TSBs, then take it to another Mazda dealer. MULTI-MODEL - VARIABLE VALVE TIMING (VVT) NOISE WHEN STARTING ENGINE - BULLETIN NOTE This bulletin supersedes the previous bulletin 01-043/07 issued on 11/29/07. The REPAIR PROCEDURE and PART(S) INFORMATION have been revised. APPLICABLE MODEL(S)/VINS 2007 Mazda CX-7 vehicles with VINs lower than JM3ER******166945 (produced before April 1, 2007) DESCRIPTION When the engine is first started, some vehicles may exhibit a loud ticking noise from the variable valve timing (VVT). This is caused by the lock pin of the variable valve timing actuator not fully engaging. Heat treatment has now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening. Here is the link to the full Mazda TSB (Technical Service Bulleting) http://www.finishlineperformance.com/pdf/cx7/bulletin/01-002-08-1896.pdf Also, here is a link to MANY other TSBs that Mazda service centers are obligated to repair free service for problems reported to customers. The 2007 CX-7 had a lot of problem (sorry, this happens with first year cars) but search this link for any others and mandate that they be repaired for free. http://www.finishlineperformance.com/store/pages.php?pageid=14

Thank you sooo much!!! This is very intersting news! I feel like I have a good chance at 'fighting' them now.  It all seems very wierd to me that last week it was a very faint noise, and now it is "not safe for me to drive." My oil nor engine light never came on, and even after double checking with the mechanic that did the oil change he still says that he did not notice anything odd at all. We will see, I will certainly keep you posted, and I GREATLY APPRECIATE your obvious car/mechanical knowledge ~with the proof of the owners manual to back it up! Thanks so much!!! pam email: ushulagirls  aol.com

Replying to: mtngirl34 (Sep 22, 2009 5:05 am) The VVT problem only causes a noisy engine as far as I know. Even after the fix, the engine is just down-right noisy still. not a problem...just noisy. Since you didn't mention the year or model of CX-7, I recommend you check several of the TSB sites such as: http://www.ford-trucks.com/tsb/tsb.php/m-MAZDA or http://www.finishlineperformance.com/store/pages.php?pageid=14 The best site for CX-7 tech questions is the really techie site http://www.mcx7.com/ There are many gear-heads and techies on this site that can answer most technical issues on the engine or eletrical. More than I want to know, but it's good to be prepared. Let me know if I can help MountainGirl |
