1978 Lincoln Mark v problems
The Continental Mark V is a personal luxury coupe marketed in North America by the Lincoln division of Ford Motor Company for model years 1977–1979, as the fourth generation of the Mark series. At 230 inches (5.8 m) in length, it was the longest two-door coupe Ford has marketed.
The Mark Vs were assembled alongside the Lincoln Continental at Wixom Assembly (1957–2007). For 1980, the Mark V was replaced by the Continental Mark VI, significantly reduced in exterior dimensions.
Chassis
The Continental Mark V shares its chassis with its predecessor, the Continental Mark IV, with curb weight reduced from 5000 to 4600 pounds.
In the interest of fuel economy, the 1977 Continental Mark V was equipped with a 400 cubic-inch V8. This engine was shared with the Ford Thunderbird/Mercury Cougar and Ford LTD/Mercury Marquis. Outside of California, the 460 V8 remained available as an option. In 1979, the dual-exhaust version of the 400 was discontinued; the 460 was discontinued in the Mark V (and in all Lincolns) by 1980.
The Ford C6 three-speed automatic was the only transmission offered.

Common 1978 Lincoln Mark v problems
The 1978 Lincoln Mark V, a luxury car produced by the Ford Motor Company, was known for its style and comfort. However, it also had several common problems that affected its performance and reliability.
One of the most common issues with the 1978 Lincoln Mark V was defective paint on the designer-series models. Buyers of these cars often had to wait up to eight weeks to receive their cars, only to find that they had defective paint that required complete resprays in the body shop. This problem was a result of American automakers' emphasis on making their cars big and fancy rather than well-made, leading to quality control issues.
Another common problem with the 1978 Lincoln Mark V was running rough. This issue could be caused by several factors, including old fuel, ethanol fuel, ignition coil, or carburetor problems. The car's exhaust leak, which sounded like it was coming from the front of the engine, could also contribute to the rough running.
The 1978 Lincoln Mark V was also known for having a trunk leak, which appeared to be coming from the topside upper left but was difficult to pinpoint. The leak could be caused by several factors, including the left drain plug, rear window area, or a drain tube on older models. Water could enter the car at one point and show up several feet away, making it challenging to diagnose the leak.
The Miles to Empty digital reader on the 1978 Lincoln Mark V was also known to work intermittently, and the problem was not repairable. The issue could be caused by the Fuel Sending Unit itself, and the best solution was to replace the module with a new one.
Finally, the 1978 Lincoln Mark V was known for having blower motor issues, with no blower operation in the heat selector position caused by the failure of the Electro Vacuum Relay module. This problem was common in the 1978 Mark V and could be resolved by replacing the faulty part.
In summary, the 1978 Lincoln Mark V was a luxury car that suffered from several common problems, including defective paint, running rough, trunk leaks, intermittent Miles to Empty digital reader, and blower motor issues. These problems were a result of quality control issues, wear and tear, and the car's complex design. Owners of the 1978 Lincoln Mark V could take several steps to address these issues, including replacing faulty parts, respraying the car, and using the proper FoMoCo manuals for maintenance and repairs.
