1991 Pontiac Sunfire problems
The Pontiac Sunfire is a compact car by Pontiac that was introduced for the 1995 model year to replace the Sunbird. Not only was the name changed, but dramatic styling changes were included as well. The new styling was shared with the redesigned Chevrolet Cavalier. The J platform was updated structurally to meet more stringent safety standards for the 1996 model year.
The Pontiac Sunfire went through two facelifts in its 11-year run: a small redesign in 2000 featuring the heavy plastic cladding look that was prevalent with Pontiac at the time, and a more streamlined update in 2003. In the US, the coupe was the only model available from 2003 to 2005. The sedan continued to be sold in Canada and Mexico until the end of production on June 22, 2005. GM replaced the Sunfire with the G5 for the 2006 model year in Canada and the 2007 model year in the United States.

The base model had the 2.2 L engine from 1994 until 2002. The GT trim level had an optional, more powerful 2.3 L Quad 4 engine from 1994 to 1995, which was replaced by the 2.4 L LD9 engine in 1995. The 2.3 and 2.4 litre engines were optional in the 2 and 4 door LS trim level. In 2003, both the 2.2 L and the 2.4 L engines were replaced by the 2.2 L Ecotec engine, and would be the only powertrain available for the remainder of production. The Ecotec engine was also an option for the 2002 model year.
At the time of introduction, the Sunfire was available with a three-speed automatic or a five-speed manual. General Motors had envisioned introducing a new four-speed automatic with the new car, but the company's cash shortage delayed this option until the next year.
