Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hi this is dave with just answer and I'm here to help. is there any other information you can provide ie. any recent work done to the car, possible accident ect.
when do you notice the problem to most? is it a vibration or a rattle?
If the engine is running well and theres no vibration from the engine itself there is a good possibility something had broken or come loose in the dash. especially if the noise is less when the glove box is opened.
maybe someone has put a radio in the vehicle in the pas and didn't secure part of the dash and now over time it came loose. the most common cause of dash vibration is weak or broken motor mounts but if those have been replaced you will need to isolate the noise in the dash next
