Safety and diagnosis
Can You Drive Before Repair?
Exhaust and emissions faults vary in urgency, but exhaust entering the cabin, severe power loss, or overheating needs prompt attention.
Stop driving or get urgent inspection if:
Exhaust fumes enter the cabin.
Power loss is severe or the converter glows or rattles after overheating.
A misfire or fuel smell could damage emissions components further.
