Any MS6 Problems?

2004 Mazda6S high idle when starting

Model: 2004 Mazda6S
Duration Owned:1 year
Mileage:49,950 (50 miles of warranty left)
Mods:K&N air filter
Fuel Octane Used:89
Problem: Idles over 2,000 RPM when starting
Conditions Under Which Problem Occurred: Always after sitting for a day min.
Steps Taken to Address Problem: taken to dealer, they claim it is normal
Resolution of Problem: none
Current Status: Sitting apart at dealer as they are replacing 3rd gear synchronizer and shifting fork and some other transmission issues. Last month it had the recall work done where they flashed the CPU and replaced the fan control mod. Also they replaced the starter because it would make a rearing noise when starting. I had complained about the high idle prior to this recall/warranty work. They claimed to not be able to be able to simulate problem. I took the car to another dealer and they also couldn't find any problems. I went in and showed them the transmission issue and the high revs. The mechanic made a confused face when the RPM was a bit over 2000 but the intake guy claimed it was normal. My question to him was if this is normal why had it never done this before 2 months ago. He explained that it will do it to warm the engine up in the winter or when it has not been driven in a while. However, again, it never did this last winter or after sitting for up to a week. I don't think this is normal but i don't know what to tell them to replace to fix the problem, that is if its a problem. Is this a problem? i have heard that the mazda supercharged cx-7 will do this but my car is not supercharged and it has had the K&N filter the whole time I've owned it. Can someone please help. Thanks

Problem: Trans doesn't want to shift properly...
Conditions Under Which Problem Occurred: Getting off of a highway and then merging onto another...


Any help here would be very helpful, I'm kinda nervous about going out and driving it right now. This morning I was on my way into work, and as I was getting off of one highway, and onto another... I was on the on ramp... and my car was staying in 6th gear. I was cruising around 40 mph, so I didn't think anything of it, but when it came time to re-accelerate onto the highway, I was pressing the gas, but my engine was not going along. Then, my trans tried to find where I was, and dropped down to 3rd gear, then it caught up with my foot on the pedal, shot up to about 5K rpm, but wouldn't shift up.

So by this time, I now have idiots flashing their lights at me, honking like I was doing something wrong... so I threw on my hazards and tried to continue to accelerate.

The car then started to do what I could best describe as someone who doesn't know how to drive a manual car... and its trying to stall, the car jerks forward and backward... but meanwhile.. it finally evened itself out... and started to slowly reaccelerate for me.

This happened to me 3 times this morning... so I pulled off of the highways and stuck to surface roads... and I had no problem. But then again, I was coming to a complete stop and it was able to drop back down to 1st gear.

Now, it was raining a bit last night, and I was pretty low on gas, so right before I got to work I filled up my tank, just in hopes that it could be water in the gas tank... but I'm not sure if those symptoms would make me believe it was water in the tank.

I'm going to take my car out at lunch time and see if it still does it when I try to get onto the highway...

Anyone have any other advice?
 
And yes, I know my car is not a speed6, but this seemed like a thread where others were giving some help for car troubles...

Problem: White smoke coming out of exhaust
Conditions Under Which Problem Occurred:after 45min of traffic and 10min at idle
Steps Taken to Address Problem: Inspected by dealer, could not reproduce the issue
Resolution of Problem: None.
Current Status: Waiting for turbo to explode/crack open under hood.
Future Plans: Find a Mazda dealer that will provide decent customer service.
 
You probably have a bad rod or syncro on your transmission. It won't cause "future" damage by driving, but not something I'd want to let sit for obvious reasons (can't shift, duh).

Happened to me in my old mustang. Of course everything broke at least once on that garbage.
 
Speed6
Ongoing issue for over a year

Between 2500-3500 rpms, and gears 2nd through 6. While under normal acceleration, not hard acceleration, engine sometimes clicks or knocks like a knock sensor going nuts. Sound comes from right side of engine, just behind glove box area. Once it clicks/knocks, dark white smoke comes out of back end. Sometimes it'll click/knock a few times, others times it's a dozen clicks. Can not accelerate during noise, lift off of throttle stops the noise, and doesn't return again for some time. Seems to happen after just going up a hill, or just coming off of a hill. Happening more lately. 30,000 kms on car.

Dealer has been arsing around for a year or more. The problem is, it never happens when they test drive it. No CEL shows, even rode around with mechanic with computer connected and sure enough, no obvious issue. Guessing fuel pump issue, waiting for more "tests" to be ran. I did just this week get the mechanic ( nice guy wanting to help) to hear the noise very briefly so at least now they take it serious.

Will update again later on.

Seems to be similar to quite a few other MS6's on this forum and others. Seems to be a rather large problem effecting hundreds if not more. Of course Mazda again denies it to be a real issue.
 
i had a loss of power on my car yesterday. like i was giving my friend a ride cuz i just got my car and it felt like the car was not as powerful as it was the first day i got it????

Fuel Octane Used: 93
Problem: Hesitation/Bucking, Lack of Power, car stalling at idle
Conditions Under Which Problem Occurred: started at 14,000 miles
Steps Taken to Address Problem: Car has been in and out of dealer continuously for the past year.
Resolution of Problem: Going back to 2007 work that has been done
1. Reflash per TSB(completed on more than one occasion) issue continued
2. Found 2 bad coil packs (replaced) bucking came back
3. Replaced Swirl Valve per TSB (replaced) bucking came back
4. Replaced MAF and O2 Sensor (replaced) bucking came back
after all of this, then the car started stalling anytime clutch was fully depressed....so then
4. Fuel Pump TSB (replaced) stalling continued
5. Clutch Type A TSB (replaced) still stalling
6. Valve replacement (replaced) still stalling
7. Solenoid replacement due to CEL (replaced) still not right
and finally after 48 days straight in the shop.....and 3 technicians
8. BRAND NEW ENGINE AND TURBO!!!
My dealer had stated that engine had no oil pressure, and even before this was found had stated that Engine from numerous road tests felt "tired" and needed to be replaced. My dealer was great through the whole process, kept me informed daily, but home office was making them jump through hoops to get the engine ordered and installed.
Current Status: Car finally back home, and drives like the day it was driven off the lot with 7 miles on it. (A new engine should do that!)
Future Plans: Hope the car never has to go to the shop for any problem again.

One of the guys I know around here has a Speed 6 that had a similar issue, and it sounded like knock, and he couldn't get the power out of the motor.

After being to the dealer several times they actually found the issue. It was a problem with the fuel system, Fisrt being a bad injector, and second was the high pressure fuel pump. THey replaced, and tested under more aggressive conditions. It's been fine for about 10 months now.
 
0o0oo0oh one more thing.. big problem i'd like everyone to check out...

whenever it rains real hard my trunk leaks water into the little space where your jack goes. I guess it is a bad body seal..anyone else have that problem??

Yes. I've had my MS6 for five years and, just this month, noticed water in the space by the jack and under the donut. Several inches of water and there's a decent amount of rust on the jack. Checked it again this week after a light rain and there was about 1/4" of water.

I can't figure out where the leak is.

Off to the body shop or the dealer?
 
to tell you the truth I haven't noticed any water build up in there in the past few months. funny thing is i have tried to simulate hard rain with my water hose and it never leaks into the trunk.

i would say to take out all the fabric panels around the jack area and wait and watch to see where it comes from.
if anything it is a bad seal and you could probably use caulk to seal it if your see where it comes from.

good luck

Sounds like a leak in one of the rear wheel wells. Water being propelled from one of the tires is probably leaking through an unsealed seam. -if I had to guess without seeing the car.
 
or a broken drain somewhere else that is redirecting to the trunk. the wife had an issue like that in her old car, was leaking from the moonroof, but she only saw water at the back window (in a hatchback)
