I've had my 2005 Mazda 6 into the shop so many times that I am embarrassed to admit. All for the same issue - the car will downshift really hard when you're doing about 45mph and you want to slowly slow down. The RPM's go up and it shifts from 5 or 6th gear to 4th. Of course, the technicians don't ever see the problem - probably because they are driving it on the freeway. I've also got the problem with it shifting hard from 1 to 2nd gear, especially when you are at a stop sign and don't come to a complete 5 second stop. This car is no longer under warranty and I've told the service rep that I'll NEVER buy a Mazda again, and that I'll tell everyone else to NEVER buy a Mazda!

I traded my crappy Pontiac for a 2006 Mazda 6i in 2-07. I think I should have kept the Pontiac!

The problems I have so far

1. Rattling noise in front end while driving

2. Transmission that either won't shift at all or slips out of gear

3. Pulls to right (sometimes hard)

4. Valve cover leaking

5. Brake squeak

6. Knocking/ rattling from engine

Last week it turned over 50k so no more warranty.

Time to trade it off ASAP.

That rattling noise no one can figure out. The transmission pops out of gear or just won't even shift at all. When I test drove the car it pulled to the right and was told it just needed an alignment. So I bought the car and took it to get alignment. To this day I have taken it in 4 times and had 3 alignments, and it still pulls mild to hard to the right. I changed the oil yesterday and noticed the top of the engine is covered with a mist of oil, and what looks like a leaky valve cover.

I am now worried about the engine. I heard a horrible rattling noise from the bottom end. Sounds like piston slap or bad crank bearing? It only has 50k miles! I think Mazda is turning out a crappy cars now.

The only good thing about the above problems is that I found out and fixed the brake squeak. On mine the squeak was the brake pad shims on the caliper. I fixed that and no more brake noise.

I have taken the car to the dealership and they have an I don't care attitude about it, and refuse to take it back. I have contacted Mazda and spoke to them, and they didn't seem to care either. So I am at wits end. If it breaks down on me, I won't and wouldn't want to pay to have it fixed, and I won't be able to trade it either.

Fingers crossed it lasts till I can trade it on something other than a Mazda!

I bought a 2005 Mazda 6s new, and cannot believe that I just found this website. I have had ALL of those problems and one more.

I have had the car die suddenly, losing all electrical power. Lucky for me, unlike like some of the above people, I was stopped at a gas station. It was like the car had an electrical storm, lights were flashing things were buzzing, the dash was going wild. It took the dealer 2 weeks to fix my car, in the end telling me it was a dead battery.

A week later I noticed the fog lamps were burned out, I really think they were blown during the electrical madness that occurred however they told me, not possible and not covered under warranty.

Next, several months later when the car was 2 years 6 months old, I noticed rust on a door window part. I was 171 miles over 50000, I was told sorry not covered, your over 50000 and it's not a part covered under the rust warranty.

Latest issues is, I notice rust along bottom edge of all four doors, the hood and wheel wells. Brought car to dealer, car is now 3 years 4 months old. Again, not rusty enough to be covered under 5 year rust warranty.

Just went and bought a fully loaded 2008 Audi A6 and dumped the Mazda. Last Mazda I will own.

I own a 05 Mazda 6, blew the engine @ 24827 miles! $4800!

For as long as I have been driving; 30+ yrs. I have always checked my oil every other wash; twice a month.

I currently have 35114 miles on the "new" engine.

Less than 1000 miles after the dealer changed the oil, I'm low 1 quart!! Anybody have similar problems? My past vehicle, a Nissan Maxima, I maintained & drove to 300k miles.

I have a 2007 Mazda 6 V6 and only has 15000 miles on it. I have had the same problem with it losing about a quart every 3000 miles. Took to the Mazda dealership (sorry to say) and they told me that they can't find any reason why it is loosing oil. It is getting worse by the month, and if the problem does not get fixed, bye bye zoom zoom. (thanks to the Colorado lemon law) I will never own another Mazda again!!!

I have a 2006 V6 ATX, last week the car stalled in stop and go traffic. I have noticed that the transmission has been shifting unusually, but not enough to convince the dealer. Wish I had got a manual instead, everything else about the car is great.

I own a 2006 Mazda 6 V6 automatic and I too have the same crappy transmission issues you've been talking about. Both the jump from 6th to 4th gear when braking going down a hill, and a transmission that slips gears and doesn't shift half the time.

My latest adventure happened when I was merging into 70 MPH traffic on the NYS thruway and the car wouldn't shift, RPM went to zero, car shut off so I lost power steering and power brakes. Lucky for me the 18 wheeler was able to swerve and miss killing me.

Have 47000 miles and have brought to Mazda several times. Maybe when I get killed my family will get some money from all my troubles. Thanks a ton Mazda.

I have been having the same "jolting" problem with my 2005 Mazda 6. When I am trying to pass on the highway or going up a hill, it also jumps out of gear, and you have to let off the gas in order for it to kick back into gear. It is in the shop as we speak, and I dropped it off on Tuesday and they tell me it won't be ready until the next Tuesday or later. They are replacing the transmission. They told me that there are a lot of broadcasts out about this problem so basically Mazda told their dealerships to take care of this problem by replacing the transmissions. Mazda really screwed up on the '05's! Otherwise, I love my Mazda and can't wait to get it back.
