1978 Pontiac LeMans

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1978 LeMans.

The 1978 Pontiac LeMans represents a specific model year within the LeMans nameplate's production history, with reliability data available through complaint tracking records spanning 1990 to 1993. During that tracked period, consumer complaints peaked in 1991 with 34 recorded incidents, while the following year saw the lowest complaint volume at 25 incidents. This complaint data suggests a notable variance in reported issues year-over-year during the early-to-mid 1990s, which may reflect either shifts in owner reporting behavior or underlying mechanical tendencies emerging as the vehicles aged. For researchers examining long-term dependability patterns, the contrast between the 1991 and 1992 figures offers a narrow but concrete window into this model's service history trajectory during its second and third decades on the road.
