Mazda Engine Repair Cost – Avoid buying the Mazda3!

Mazda 626 

The Mazda 626 was first used in the 1970 model year and stayed in production from Mazda for over 3 decades. Designed originally to compete against other similar cars like the Honda Accord, Toyota Corona, and Ford motor vehicles, the Mazda 626 was also called the ‘Mazda Capella.’

Auto Repairs Are EXPENSIVE

Spanning over six generations, the Mazda 6 was a popular vehicle on the market, offering compact class size and a mid-size layout after 1987. Despite the popularity, the Mazda 626 has had safety and reliability concerns throughout the years – especially focusing on the Mazda engine repair cost.

The worst model years of hte Mazda 626 are the 1998 model due to the severity, prevalence, and a number of issues, with the most-reported problem being the transmission failure in the 1998 Mazda 626. The worst categories of concern are the transmission, engine, cooling system, and exhaust system. 

The main engine issues focus on the cracked head gasket, the car running roughly, and the car not starting when the engine is warm. The typical repair cost to fix the cracked head gasket is around $1,000, with the average mileage coming to around 135,000 miles. A cracked head gasket is a severe issue that needs to be fixed after noticing the problems to avoid a higher Mazda engine repair cost.

Mazda CX-5

The Mazda CX-5 is a compact crossover SUV with a 5-door body style and a front-engine, front-wheel-drive, or front-engine, four-wheel-drive layout. Sharing a platform with the other popular Mazda 3 and Mazda 6, the Mazda CX-5 is the first car produced by this company to use the SkyActiv technology.

SkyActiv technology is a mechanism that increases the fuel efficiency of the car and engine performance. Despite using this technology to reduce emissions and reduce fuel consumption, the Mazda CX-5 had its fair share of concerns regarding engine reliability and a high Mazda engine repair cost. 

The worst model years of the Mazda CX-5 are 2013, 2014, and 2016 years. The 2016 has the most-reported issue of the daytime-running LED, causing electrical failure, also making this the least reliable and worst model in terms of owner reviews. 

The 2016 Mazda CX-5 had top problem categories focusing on the interior accessories, lights, windows and windshield, brakes, transmission, electrical parts, and the engine. Owners cited issues with the faulty oil filter screen, excessive oil consumption, and high RPMs while driving the Mazda. 

To fix the faulty oil filter screen, the most common solution is to replace the faulty oil pressure sensor at just below 2,000 miles, making this a very early-on problem that can lead to a high Mazda engine repair cost if left untreated.

Furthermore, fixing the excessive oil consumption typically occurs at around 62,000 miles, with owners stating that the car is in a non-operating condition and the engine does not perform as it should.

Mazda CX-7

The Mazda CX-7 is a midsize crossover SUV produced by Mazda, with the car shown publicly for the first time during a 2006 Auto Show. Produced from the model years 2006 to 2012, the Mazda CX-7 uses either a front-engine, front-wheel-drive, or front-engine, all-wheel-drive layout.

Equipped with a variety of engine types like the 2.3-liter MZR L3-VDT turbo l4, 2.5-liter MZR L5-VE l4, or the 2.2-liter MZR-CD l4 diesel, this type of vehicle has many performance capabilities. However, this car is prone to engine difficulties, resulting in a higher Mazda engine repair cost for your Mazda CX-7.

The top three concerns across all model years include the engine timing chain malfunctioning, the turbo going out in the 2007 model year, and the engine failing in the 2008 CX-7 at around 107,000 miles.

The other most severe problems in the engine category are the turbo going out, the car losing all power while driving, the engine making a ticking noise, the timing chain breaking, the check engine light turning on, the car dying while driving, the car stalling and stuttering in rainy conditions, and the turbocharger failing due to the engine cooling system.

Replacing the engine timing chain is an expensive fix, with the most common solution being to replace the entire mechanism at around 80,000 miles for nearly $2,700. Owners state that the car sounds very loud while driving, the car has trouble accelerating, and the VVT and timing chain catch during use. 

The other severe problem in the 2007 Mazda CX-7 is the turbo going out during use, causing the owner to replace the entire turbo mechanism at around 87,000 miles and costing the car owner nearly $3,000.

Fixing the water pump failure costs nearly $4,000, with owners stating they have to replace the entire unit with a rebuilt or used engine at around 102,000 miles. Unfortunately for Mazda CX-9 owners, replacing the engine is the only fix to solving this issue, resulting in an expensive Mazda engine repair cost.

Available in either a 4-door sedan or 5-door hatchback, this car is the fastest-selling vehicle in the company’s history, reaching an impressive 6 million units sold. However, this does not mean it is without its concerningly-high Mazda engine repair costs. 

The worst model year of the Mazda3 is by far the 2010 option, with the year having the most-reported issue of clutch failure and the most severe concerns. In addition, the top three problems across all of the model years of the Mazda3 focus on the clutch failing and the gears grinding in the 2010-2012 years.

Ownes state that the car continually revs high during use. The car unintentionally accelerates while braking, the car chokes after firing up, the engine stalls and dies while driving, and the valve VVT system fails. 

Owners state the high revving can be fixed by replacing the throttle body at around 11,000 miles and costing owners around $630 to fix. This is a relatively inexpensive Mazda engine repair cost.

Developed together with Ford and based on the Mazda 626 vehicle, this Mazda TRibute was a cheaper option for those looking to buy the Ford Escape.

With two generations, the Mazda Tribute reached its peak sales year in 2002. However, the Tribute soon declined and saw owners staying away from purchasing the vehicle due to the high Mazda engine repair cost. 

The worst model years of the Mazda Tribute are the 2001, 2005, and 2008 years, with the 2005 having the most-reported problem of the wheel well area completely rusting after use.
