Gmc Sonoma Years to Avoid
The 1994 model year is the worst Sonoma to purchase, with fuel pump failures, transmission problems, and ABS brake issues dominating complaints. 1991-1995 models suffered from Central Sequential Fuel Injection spider injector failures causing rough running. 4L60E automatic transmission failures were common in towing and heavy-use applications. Lower intake manifold gasket failures on 4.3L V6 engines caused coolant leaks and overheating. ABS module failures left owners with expensive repairs.
Best Gmc Sonoma Years
The 1990 model year predates the Sonoma name, but 1996-1998 models with the improved Vortec 4.3L V6 are more reliable. 2000-2004 final years represent the most refined Sonoma production. The simple 2.2L four-cylinder is the most trouble-free engine option.
