2015 Subaru Impreza wrx problems

General information about Subaru-Impreza wrx
Overview of popular issues

The Subaru WRX is an all-wheel drive sport compact car manufactured by the Japanese automaker Subaru, originally based on the Impreza created for the World Rally Championship in 1992. Subaru claimed the name WRX stands for "World Rally eXperimental". Starting with the 2015 models, the WRX lineup has been split from the Impreza, with a different body style that is not offered as an optional hatchback/wagon, being introduced as the separate Levorg model.

Impreza-based models (1992–2014)

The first three generations of the WRX, sold until the 2015 model year, were based on standard Impreza platforms, and replaced the Subaru RX hatchback and sedan.

The initial first-generation WRX models were based on the Impreza sedan (GC chassis code). They were followed by wagons (GF) in 1993 and the first upgraded WRX STi version, introduced in 1994. Several limited edition first-generation coupés were offered in the late 1990s and early 2000s which were never sold in the US and are highly sought after by Subaru enthusiasts.

The second-generation WRX (GD/GG chassis codes for the sedan/wagon, respectively) was brought over to the United States domestic market for model year 2002, with the STI being brought over for model year 2004. The initial "bugeye" front end styling (2000) was superseded by the "blobeye" in 2004 and the "hawkeye" in 2006. Under an agreement between Fuji Heavy Industries and General Motors, Saab sold its own version of the WRX, marketed as the Saab 9-2X, for the 2005 and 2006 model years. The 9-2X was available in both a standard (Linear) and performance (Aero) package, the latter was essentially identical to the second-generation WRX wagon, mechanically.

The third-generation WRX were sold as chassis codes GE (sedan) and GH (hatchback, replacing the earlier wagon version) initially; the third-generation WRX STI was sold with a widened chassis and was available only as a widebody hatch (GR). For the 2011 model year, the third-generation WRX sedan and hatch were moved to the GV and GR wide-body chassis variants, respectively, and a widebody sedan version of the STI (GV) was marketed. The Impreza was redesigned and the fourth-generation was first marketed for model year 2012, making it a distinct model from the WRX, which continued on the third-generation GV/GR chassis until 2014 in most markets.

The fourth-generation WRX were given the VA chassis designation and marketed as a separate model from the Impreza starting in 2015.
