Automatic transmission failure: very sluggish or hard shifting, failure to shift out of park, complete failure requiring rebuild, often at low mileage (e.g., 85,000 miles); flashing Overdrive (O/D) Off light is a common warning sign. Frequency: very frequent.
Cooling system problems: persistent overheating, coolant leaks from the reservoir, suspected clogged radiators, thermostat failures; issues often exacerbated by using air conditioning. Frequency: very frequent.
Electrical and sensor issues: intermittent turn signal failure, alternator/voltage regulator problems causing battery drain, rough idle and stalling linked to faulty sensors (MAF, O2), malfunctioning neutral safety switch. Frequency: recurrent.
Engine running problems: rough idle, stalling when cold, hesitation on acceleration, misfires; often related to fuel delivery (pump, injectors) or ignition components despite replacements. Frequency: recurrent.
Structural and body issues: susceptibility to rust, particularly in older generations; noted as being rust-prone in certain climates. Frequency: isolated.
