Known issues on the 1993 Sonoma. Four recalls are recorded. The one with the widest reach is an automatic transmission whose low and reverse clutch wears until the park pawl cannot engage, so a truck left in park can roll away. Two more cover service fuel parts that can leak: a return line missing its bleed valve, and a poorly sealing replacement filter. The fourth is an antilock system misreading which drive mode the truck is in and stretching a stop. Brakes lead the 73 complaints, ahead of power train and engine cooling, and all three have diagnostic sections here.
