2021 Mazda Mazda6 problems
The Mazda6 (known as the Mazda Atenza in Japan, derived from the Italian attenzione) is a mid-size sedan produced by Mazda since 2002, replacing the long-produced Capella/626.
The Mazda6 was marketed as the first example of the company's "Stylish, Insightful and Spirited" design philosophy, followed by the Mazda2 in December 2002, the RX-8 in August 2003, the Mazda3 in January 2004, the Mazda5 in the summer of 2005, the MX-5 in October 2005, and the CX-7 in November 2006. The 2003 Mazda6 is essentially the seventh-generation Mazda 626, part of the 'G' model code family.
First generation (GG1; 2002)
The first-generation Mazda6 was launched in Japan as the Mazda Atenza in May 2002. The model lineup consisted of a four-door sedan, a four-door hatchback and a five-door wagon, marketed in North America as the "Sport Sedan", "5-Door" and "Sport Wagon", respectively. In Australia, the lineup was first available in Limited trim, as a sedan; in Classic trim as sedan, hatch or wagon and in Luxury trim as a sedan and liftback — and Luxury Sports trim, as a liftback. In New Zealand, the lineup consisted of 2.0L GLX (sedan only), 2.3L GSX (sedan, liftback, and wagon), and 2.3L Limited (sedan and liftback).
The first generation was marketed as a 2003 model in the United States and as a 2004 model in Canada. In Europe, the luxury sports model was available as a 120 hp (89 kW) direct injection turbodiesel ("DITD") estate up until 2007. As of 2008, the European Mazda catalog listed only the "Sport" version of the 146 hp (109 kW) turbodiesel estate, while the "Luxury Sport" version had been dropped.
Drivetrain combinations included the Mazda MZR engine in configurations of 1.8 L (L8-DE), 2.0 L (LF-VE) and 2.3 L (L3-VE), initially with a five-speed manual or four-speed automatic transmission (with a sequential-automatic option, dubbed the "Four-Speed Sport AT"). In the US domestic market a 3.0 L Duratec 30 V6 engine was also available with a five-speed manual or five-speed automatic (with a sequential-automatic option, dubbed the "5-Speed Sport AT"). European and Australian versions also feature a four-cylinder turbodiesel that comes with a six-speed manual transmission and produces significantly more torque than the V6, with much improved fuel economy.
In North America, the 5-speed automatic optional on the V6 models were replaced by an Aisin 6-speed automatic for the 2005 model year. The four-cylinder model received a Jatco five-speed automatic in the following year. Power was directed to the front wheels in most markets, although full-time all-wheel-drive models were available in Japan, Europe, and Australia. Not all configurations were available in all areas – for example, the Mazda 6 as released in Australia was available in 2.3L four-cylinder guise only, when the 626 it replaced had been available with a choice of four- or six-cylinder engines. The MZI V6 engine was only fitted to vehicles manufactured at Mazda's Flat Rock Assembly Plant and destined for the U.S. and Canadian domestic markets.
Mazda's Hofu Plant in Yamaguchi Prefecture produced the Mazda6 for international markets from February 2002 to August 2007. In North America, Mazda6 production was handled at the AutoAlliance International plant in Flat Rock, Michigan. The first Mazda6 rolled off the AAI assembly line on October 1, 2002, one month after 626 production ended. There are also satellite plants building Mazda6 models in China and Thailand for local markets.
In September 2005, the Mazda6 received a facelift which introduced 5-speed auto and 6-speed manual transmissions, standard 16- or 17-inch alloy wheels, and minor bodywork upgrades.
In China, the Mazda6 was introduced by FAW Mazda in 2003. Despite the release of its successors, the first generation car, known locally as the Maliu (马六, "Horse 6"), continues to be manufactured at FAW's Changchun plant, having sold over 770,000 units as of 2014. This model is also used as the base for the FAW Benteng, also known as Besturn B70 or Hongqi C301.

ENGINE PROBLEM
- Date Of Incident: 2022-07-13
- VIN: JM1GL1WY7M1
- Components: ENGINE
- Summary: The low oil pressure light had turned on shortly after my first oil change (roughly at around 6k miles). I had the service done at a trusted service shop back in April 2021. I wrote it off mentally thinking that it was just a one off thing and that the shop may have made a mistake and underfilled the engine because of unclear specifications between the mazda6 Turbo version vs other models within the same lineup. I measured the oil and confirmed it was low and topped it off with over a half quart of oil and never bothered with it again. Six months later I return to the same shop for an oil change at 11k miles. I had no issues up until the 17k miles month mark when I am about to schedule the oil service the low oil pressure light turns on once again. I top it off and go online to see similar experiences with the same issue experienced by other drivers.

Great seats, comfortable ride, good acceleration and accessories!

Very responsive, handles like a dream, and you won't see many on the road. This is a rare beast!!

I hope you're doing well! I wanted to share my experience with the Mazda6 sedan. It's a great car that's comfortable, reliable, and inexpensive to run. The ride is smooth and relaxed, making it perfect for long drives. Plus, it's got enough sport and zoom-zoom to make back-road forays enjoyable. Our Mazda6 is one level above the base, so for less than $28k, we get a naturally aspirated and responsive engine that's proven to be reliable. We expect to get a decade or more of low-hassle performance from it. It's not an SUV or a jacked-up truck, but it's perfect for our needs. The only negatives are the infomatics (but Car Play works well) and sound quality, which could be better. There's also a bit of wind and tire noise at high speeds. Overall, it's a good car from one of the industry's top-rated brands that will last and continue to work. Thanks for listening!

Sporty handling with a smooth ride and a great interior.

Great car! It feels like a luxury vehicle.

Are you having problems with your 2021 Mazda Mazda6?
Arely Harber 2024-08-09
I recently leased the 'carbon edition'. Although it is a Japanese made car, I did not check out the technology it came with. If I had, I doubt that I would have leased it. My biggest complaint is that it does not have a touch screen, unlike my 2018 Charger and 2019 Mustang which both have touch screens. The screen itself and toggle switch are not user-friendly and have not been updated in this 'special' model. If I am driving and want to change a destination, I have to pull over, put the car in park, put the emergency brake on, and then change where I want to go. On a positive note, the car is quick, handles like a dream, and is comfortable. However, it is way behind in terms of the technology used. If you are looking for updated tech, consider something else.

I hope this message finds you well. I wanted to share my recent experience with my new 2021 Mazda 6 Touring Plus. During the point of sale, I noticed some paint chipping on the hood and side panel. The dealer has kindly offered to touch it up, but I have since learned that this is a common issue with many Mazdas. Although I am a bit concerned that I may have purchased a lemon, I am happy to report that the car drives well. Thank you for your time and attention to this matter.

Hi there! It seems like there might be an issue with the fob as the trunk keeps opening on its own even while driving.
Reymundo Jenkins 2024-06-12
I always wanted a Mazda 6 Grand Touring. I finally bought a brand new 2021 Mazda 6 GT, but I am disappointed with my purchase. The engine has a 0 to 60 time of 7.1 sec and lacks the power I was hoping for. Additionally, the vehicle feels heavy and unsporty, making it difficult for me to get in and out of the car. While the infotainment system looks outdated, I do appreciate the center knob near the shifter. Overall, I am considering trading in this vehicle for something that better suits my needs and preferences.
Jessy Hamill 2024-05-11
I went to test drive this car, but unfortunately, it did not meet my expectations. Although it looks beautiful and well-made, the interior seating, even with the signature comfort seats, was too firm for my liking. The back seats were also uncomfortable due to their straight and hard design. Additionally, the technology and interior seemed outdated compared to other options in this price range. I have driven a Kia Optima from 2015 that was more comfortable, had better technology, and was easier to drive. Considering the price of the Signature, there are much better options available. I did have a minor issue with the salesman driving the car for 5 miles before handing it over to me, but in hindsight, it gave me ample time to realize that this car was not the right fit for me.
