2006 Mazda 6 i 2.3 naturally aspirated 4 cylinder from North America


A++ This is a wonderful car; reliable, safe, sexy, economic, fun and luxurious all at once!


I haven't had any real problems with it.

When I bought it used at the dealership, after putting a few miles on it I started to have a rub/click when turning. All it turned out to be was insufficiently greased CV axle boots.. Took it to the dealership, and they covered it under the factory warranty.

Front suspension is a little squeaky at times, but nothing bad at all.

General Comments:

I really love this car, I bought it for $14k. It is fast and sporty, but at the same time it's a luxurious and safe family car.

I'm really impressed with the fuel economy as well as the cabin room; it is very spacious and comfortable.

It handles great around tight corners. The traction control and 4 wheel ABS system is awesome, it does very well on ice/snow.

It has a nice sound system.

It is quiet at highway speeds, and has very little interior noise.

My factory warranty expired Oct. 09, so I went and bought the extended warranty (10 years or 100,000 miles, whichever comes first.) It was well worth the money because I'm under warranty for the next 6 yr/70k miles!

I would definitely recommend this vehicle to friends/family. It is a great buy for your buck.

Would you buy another car from this manufacturer? Yes

You say or admit that your Mazda 6 is "..economical...". Good to hear that and congratulations. Enjoy your car.

Would you be extra kind to indicate for my education what are your real fuel consumption figures, the size (cc) of your engine and type of transmission (auto or manual? I'd greatly appreciate that as I am contemplating grabbing one.

Presently I drive a 4-door saloon '99 model 1.6 litre Mazda Protege with 4-speed auto. I dread, really dread the fuel consumption - nightmare! My best consumption in town ride with carefully regulated right foot and max 70km/h speed is 8-9km/l without the use of the AC. Surely I guess something must be wrong. Any one with ideas about overcoming this dread and nightmare?

Otherwise, no car beats Mazda reliability.

2006 Mazda 6 Mazdaspeed6 2.3 turbo DISI from North America


Took a deep breath and threw a party as soon as I saw its new owner drive away


I bought a "corporate demo" Speed6, which had been driven by the sales manager of my local dealership.

7,200 miles - Power loss after having the dealer install Sirius and upgraded alarm. Turbo had basically shut down, but car was cold when I picked it up, and I drove it 30 minutes home and 30 minutes back with no turbo at all. This was 7 days after purchase. Quite an omen.

10,000 miles - My brakes started squeaking badly. The pads and rotors were replaced under warranty. (see again at 32,000)

14,000 miles - Electrical issue; driver's heated seat will not deactivate regardless of switch position or even car being completely off with key removed. Caused numerous dead batteries.

32,000 miles - Brake noise reappears and after my insistence pads are replaced and rotors resurfaced under warranty.

32,500 miles - Turbo is blown; large plumes of white smoke pouring out of exhaust after idling. Like a Batman smoke screen. I was literally afraid to back up. Turbo is replaced under warranty.

32,501 miles - Metal on metal ping / significant stutter (gasp) from engine at 3500 RPM. While accelerating at moderate throttle (merging into freeway traffic) during 3rd or 4th gear car would suddenly loose power as if gasping for air and then surge. This was accompanied by a metal on metal clang that gradually got louder over time.

After seeing 4 different dealers, only one would acknowledge the problem, but it was never remedied. I was able to prove that this eventually lead to complete engine failure at 52,000 miles.

52,000 miles - Complete engine failure; rod bent in two places, causing piston to shatter and crankshaft to puncture engine block. Coincidentally it occurred while downshifting from 4th to 3rd gear while braking and slowing for a light. Car shut off just as it reached 3500 RPM.

After almost two weeks of "diagnosis", Mazda accepted liability and replaced the engine (including clutch) for what paperwork said was just under $13,000.

52,200 miles - Car fails to start, but all electronics (wipers, lights, stereo, etc.) are functional. Starter will not even actuate. Dealership blamed this on a bad battery that had been replaced by the dealer only 5 months prior.

52,400 miles - Car vibrates and shuts off while driving. Refuses to restart (identical behavior as issue above at 52,200 miles). This time it is diagnosed as bad coils on new engine.

52,440 miles - Grinding noise in first gear and whining noise in second gear appears. Dealer diagnoses as a "shifted engine mount causing engine to ground out." Whatever that means!

52,441 and on - Dealership tells me that the rear differential is binding. They blame it on different brand tires on front and rear (even though a Mazda dealer gladly installed them and I have the invoice in hand).

What I found appalling is that they use that excuse, yet somehow did not notice this problem in the 6 previous test drives for the other problems in the 3 weeks prior.

I bought a new car a week later, and sold the Speed6 privately for a significantly reduced price, while disclosing all this history and transferring Mazda extended warranty into the purchaser's name. I did run into him a month later though, and he mentioned that the car would occasionally refused to start for hours at a time. It looks like the problems I suffered at 52,200 and 52,400 are still open issues.

I have owned 6 cars now (3 imports and 3 domestic), and have never had any problems even close to this magnitude. I do think many of the problems were exacerbated by poor training of Mazda technicians. I often knew what was wrong while they were still trying the "PCM reflash", which was done a total of 4 times. Only once was it effective.

General Comments:

This car was an absolute neighbor, and actually became a joke to my co-workers and my neighbors because it was usually in the shop about once a month. In addition to the many major mechanical issues above, there were always some minor irritations.

Advanced Keys are worthless and work only about 80% of the time, often causing my car to unintentionally stay unlocked in unsafe areas or refusing to let me in during a downpour. The one good thing is they will never let you lock your keys in (as long as they are working that day)

Rattles - The navigation system rattled incessantly whenever open. It was more pleasant to close the screen and just listen to the speech prompts.

The moonroof rattled since a few days after I picked up the car, but only on hot days. I complained about this at 10,000 miles, but no one attempted to address it until 37,000 miles, and it turned out to be a loose bracket at 42,000 miles. Some follow through huh?

The passenger side dash vent sticks and then rattles. This can be rectified by leaning over and moving it slightly, but it's still annoying.

The speakers in the Bose system always sucked.

Tire wear was pretty bad, but not as bad as some experienced.

The radio system is so outdated that the song title will not clear when a new song comes on. So if you are listening to Kings of Leon and then MGMT comes on, the radio will display "MGMTs of Leon."

The POSITIVE - I did enjoy this car, when it ran. I thought it was very good looking and performed great. Although I bought it for the all-wheel drive, I never expected it to perform like an EVO or WRX. It always felt very solid, and for the limited trunk space, I managed to pack a ton of stuff into this thing for many road trips. It was definitely the car of choice for trips among my friends. I thought the front seats were quite comfortable, but I am slender. I have sat in them for 10 hours straight.

Two other design oversights that frustrated me every time I was given the dealers loaner 3. Why does the 3i get a one touch moonroof and a trip computer, but we don't? That car costs HALF as much. I think I actually enjoyed driving the 6S wagon they also had as a loaner vehicle.

Would you buy another car from this manufacturer? No

Sounds like a serious problem with your dealer. It's funny you hear these stories in the US but not Australia. Or you hear stories about Australia but not he USA. I guess they are different batches with different problems. I guess that's why these are personal reviews and you can't judge the whole car on a few of these issues.

I had a 06 Speed6. I was with it in the shop about every month. Bought a used 03 Cobra and haven't looked back. Poorly built car for Japanese. I expected reliability.

Buying a demo is like buying a rental. They'll tell you some older executive had it, but anyone who gets a hold of this type of car is going to beat it when they can just dump it and get another at no cost to them. I used to sell cars, and the salesmen were the most abusive drivers. I'd never buy a demo, no matter what the discount, as you are just asking for problems.

Not saying that caused all of your problems, but it may have been a factor for a blown turbo and other premature engine failures. Glad to hear you at least told the new owner of all the problems. I would have traded it in and let a dealer deal with it myself, instead of putting another owner in the position I was in.

While I've not had your other issues (feel so sorry for you), I went through the same situation with the engine. My dealer could never fix it either. It died shortly after shifting into 3rd on a 35 MPH road with no warning before it happened. Close to 60,000 miles. Hadn't considered liability. Thanks. I'm going to look into that.
