When researching 1980 BMW 7 Series reliability, the key theme is that these cars can be dependable classics when sorted, but age-related wear and deferred maintenance drive most “1980 BMW 7 Series problems.” The following are among the most common issues owners report: 1) Cooling system weaknesses and overheating: Radiators, hoses, thermostats, and especially the water pump can fail from age. Overheating risk rises if maintenance history is unknown, commonly showing up anywhere from 60,000–120,000 miles depending on prior service. An overlooked cooling system can lead to head gasket trouble, so prevention is critical. 2) Fuel injection and drivability issues: Bosch injection components (sensors, injectors, fuel pressure regulator, and vacuum lines) can cause hard starts, rough idle, hesitation, or poor fuel economy. Vacuum leaks are especially common on older E23s due to brittle rubber lines. Problems often appear after long storage or around 80,000+ miles, but age is the bigger factor than mileage. 3) Electrical gremlins and charging problems: Alternators, voltage regulators, aging grounds, and fuse/relay issues can create intermittent no-starts, dim lights, or accessory failures. Power window switches and central locking components may also act up. Many “common issues” stem from corrosion and old wiring rather than a single defective part. 4) Suspension and steering wear: Control arm bushings, ball joints, tie rods, and steering components can loosen, causing vibration, wandering, clunks, or uneven tire wear. Expect suspension refresh needs as mileage climbs past 100,000 or on cars that have sat, since rubber degrades over time.
