Analyst Adam Jonas set a new price target of $134 down from $149.
Jonas expects the Southfield, MI-based electrical and automotive seating manufacturer's earnings will peak this year and fall 20% by 2021.
The downgrade comes amid Jonas' "big cuts" to U.S. auto industry sales forecasts, The Fly reported. He reduced annual unit forecasts between one million and four million.
High development costs, increased competition and potential lost market share all suggest trouble for electrical business margins.
Lear shares traded down 2.6% in early market trading.
