What Problems Does the 1985 Mazda RX-7 Have?
The 1985 Mazda RX-7, like many rotary-powered vehicles of its era, is known for specific long-term reliability concerns that owners should be aware of. The most significant and frequently reported issue revolves around the apex seals within the Wankel rotary engine. These seals are critical for compression and, over time and with improper maintenance or abuse, can wear out, leading to a loss of compression, rough running, and ultimately, a need for an expensive engine rebuild or replacement. While the 1985 model year itself didn't have major model-year-specific widespread recalls directly impacting apex seals, the inherent nature of the rotary engine means this is a constant vigilance item for owners.
Another common concern is overheating. Rotary engines generate a lot of heat, and a poorly maintained cooling system (clogged radiator, failing water pump, or worn hoses) can quickly lead to engine damage. Oil consumption is also a characteristic of rotary engines; they are designed to consume a small amount of oil to lubricate the seals. However, excessive oil consumption can indicate internal issues. Rust is a significant enemy of older cars, and the 1985 RX-7 is no exception. Common areas for rust include the wheel arches, rocker panels, floor pans, and the unibody structure, which can compromise the vehicle's integrity and lead to costly repairs. Electrical gremlins can also crop up in older vehicles, including issues with the fuel injection system, sensors, and the dashboard electronics. While Mazda made improvements throughout the RX-7's production, the rotary engine's unique design requires specialized knowledge for maintenance and repair, which can sometimes make finding qualified mechanics a challenge.

How long will the 1985 Mazda RX-7 last?
Estimating average mileage for a 1985 Mazda RX-7 is challenging due to its age and the enthusiast nature of many owners who may drive them less frequently or extensively rebuild them. However, a well-maintained RX-7 can certainly surpass 200,000 miles, though this often involves engine rebuilds. The rotary engine's long-term durability is directly tied to meticulous maintenance, especially consistent oil changes and vigilant monitoring of coolant temperatures. Weaknesses emerge over time primarily in the apex seals, which can necessitate rebuilds around the 100,000 to 150,000-mile mark if not replaced proactively or if driven hard without proper care. Rust also becomes a significant long-term concern as the chassis ages.
What Technology & Safety Features are Included?
The 1985 Mazda RX-7, reflecting its era, offers a relatively basic suite of technology and safety features compared to modern vehicles, but it was well-equipped for its time. Standard technology often included an AM/FM stereo with a cassette player, power windows, power door locks, and power mirrors. Optional upgrades for entertainment could include a more premium sound system with more speakers. There was no built-in navigation or advanced infotainment systems as we know them today.
Driver-assistance features were virtually non-existent. Modern amenities like cruise control were available, especially on higher trims like the GXL, and power steering and brakes were standard, enhancing the driving experience. ABS (Anti-lock Braking System) was not a common feature on the 1985 model; it began appearing more frequently in later years and on specific performance variants or as an option on some higher trims, but was not widespread.
Safety features were limited to seatbelts (three-point front, lap rear) and the structural integrity of the car's chassis. While Mazda engineers focused on weight distribution and handling for active safety, passive safety systems were basic. Airbags were not standard equipment in 1985 for the RX-7. Regarding crash-test ratings, specific official ratings for the 1985 RX-7 from organizations like the NHTSA or IIHS are not readily available or as comprehensive as they are for contemporary vehicles. However, it was designed with a sporty but robust unibody construction. The focus was more on driver control and preventing accidents through handling rather than mitigating damage in a collision through advanced safety systems.
