Windshield Wiper Motor Cold-Weather Failure

Electrical · severity: Moderate in the specific conditions where it occurs (NHTSA's own wording: reduced visibility increases crash risk). Real-world relevance for a South African-delivered/used vehicle is likely lower than in the US market, since the defect is specifically triggered by "certain cold temperature conditions" that are uncommon across most of South Africa's climate - noted honestly rather than omitted, since this is still a real, filed federal recall regardless of how often SA conditions would trigger it. · confidence: 82/100 · 3 cited sources
Applies to: 5.0L Ti-VCT V8 (4th-generation "Coyote") / 2.3L EcoBoost - not every engine this model has been sold with
ⓘ Not yet individually classified

Symptoms to watch for

  • In cold conditions, windshield wipers may function only at their high-speed setting (cannot be set to low/intermittent)
  • The windshield washer system may fail to function properly

What To Check

Only detectable in cold conditions specifically, which is uncommon on a typical South African test drive - check recall status by VIN rather than relying on test-drive observation.

Catalytic Converter Failure (PCM-Related)

Emissions/Exhaust · severity: Moderate - an emissions/MIL issue with a real, documented, warranty-eligible fix, not a safety-critical or drivability-threatening fault in most cases · confidence: 82/100 · 1 cited source
Applies to: 5.0L Coyote - not every engine this model has been sold with
ⓘ Not yet individually classified

What To Check

Not detectable on a test drive - this presents as a stored fault code and illuminated Check Engine Light (MIL), not a driving symptom. A pre-purchase OBD scan is the reliable check for a 2018-2019 automatic 5.0L Mustang built on or before 23-Apr-2019.
