Symptom: Whining, a CVT overheat warning on long climbs or hot days, loss of power or limp mode.
Likely causes
- Fluid and cooling. Patriot owners report fixing whine with a correct fluid and filter service at the proper level, and fixing overheating by replacing the cooler bypass or adding a cooler.
- Wear. Repeated limp mode with codes often means the CVT is failing.
