#66 of 89 2008 CX-9 GT - Check Engine Light? by tammye Aug 05, 2008 (7:45 am)
Has anyone had their CEL light come on? Mine came on with 4,740 miles and has now been in the shop for 8 days. They replaced the mass airflow sensor; picked up car at 5:30 pm after 3 days; parked car in garage; drove 1 mile the next morning and light came back on; car was back at shop at 9 am. I am pleased that Mazda has given me a rental. GMC would not do that. Any suggestions? They have spoken to 4 Techs at Mazda and no one seems to have a clue.

Replying to: tammye (Aug 05, 2008 7:45 am) tammye, Since CEL is on, there must be error codes thrown in OBDII. The tech can scan them and debug the issues from there. In the Workshop manual (they all have one), it lists all the possible causes for certain code. They just have to check all the possibilities. Apparently, their 1st try failed (they thought they did it). Since you have a loaner, let them do the job.   Did you go to a Ford/Mazda dealer? I would recommend an independent Mazda dealer if possible. They usually are more competent when it comes to Mazda vehicles. That is just my opinion.

Replying to: ceric (Aug 05, 2008 9:24 am) It is at a Mazda/Hyundai dealership. They have reported to me that they have checked all the codes and can not figure it out. I was just wandering if anyone else with this model has had a problem. I have found out the CX-7 has had this problem. I'm wandering if it could be the same thing on the CX-9. Thanks.

Replying to: claireb (Jul 30, 2008 8:49 am) Well, we decided to take it to the dealer we bought it from and they fixed it straight away.   My husband is very impressed with the service we were given - they even cleaned the car! Not that it was dirty, but it was a nice touch! Replies to this message: tidester (May 14, 2009 9:25 pm)
#70 of 89 gas and oil by cry1ray May 14, 2009 (9:01 pm)
Just bought an 09 CX9 and wondering should I put super unleaded gas and also should I use synthetic oil. Any thought anyone??   Thanks Replies to this message: ceric (May 14, 2009 10:52 pm)

Replying to: cry1ray (May 14, 2009 9:01 pm) Regular 87 octane is what is needed for the our MZI 3.7L engine. Going upward will not gain anything since the compression ratio of 10.3 is not that high for the engine to benefit from higher octane.   Synthetic oil may help a tiny bit on the MPG, and can prolong the oil change interval up to 15,000 miles (i.e. 3X longer). It also helps reduce wear on cold starts. However, the oil is nearly 3X as expensive. You might also void your warranty if you decide to change your oil at 15,000 interval should anything bad happen to your engine. My advice is that do synthetic after the OE powertrain warranty runs out. After that, do whatever you want (synthetic or not). It is a matter of trade-off.
#73 of 89 Car won't start by staggs May 21, 2009 (6:15 am)
I turned off my 2007 CX9 while in gear last night. Realizing this I put it in park. When I went to restart it approximately 5 minutes later it would not start. Battery is fine, fuses are all good, don't know what to do next. Replies to this message: eua (May 21, 2009 7:21 am) ceric (May 21, 2009 9:03 am) ceric (May 21, 2009 9:05 am)

Replying to: staggs (May 21, 2009 6:15 am) I do the same by mistake time to time on my both cars and do not have any problems. I think your problem is something else. Call your dealer and let them fix it. Do not say anything about what you did before. They can be very mean and blame you that everything is only your fault and try to make you look stupid. Let them investigate the problem on their own. I really do not think that switching gear on not moving car with engine off can hurt.

Replying to: staggs (May 21, 2009 6:15 am) "would not start" needs more clarification. If there is no cranking, I am betting that the interlock is somehow at fault. The system prevent one from starting engine at any gear other than P. That is obviously for safety reason. Yours somehow may be broken. Therefore, the system still think it is NOT in P position. Just my guess.
