I have had three exhaust solenoid failures in the last 4 months. The first failure was after more than three years since I bought the car new. Looks like the solenoid is not the root cause. Any ideas anyone?

Mine have failed too

Unplug them, buy sharkwerks bypass.....be happy

Failure is quite common but 3 of them in 4 months?
Did they check the vacuum lines?
Maybe there is a leak and solenoids are working overtime?

I just replaced my port side exhaust solenoid, but its failure was apparently caused by smacking it when emerging from the exit tunnel at TX World Speedway. The parts guy at Sun Coast did tell me that they are selling quite a few of them.

I know this might be a bit off base but any chance that you're pulling in our out of a steep driveway on a regular basis? Seen those things smack the curb/road a good few times and bend/brake the heck out of them.

It's not uncommon for them to fail.. but three times so far is a bit much

how would you know if you have a solonoid failure. What tell-tale signs, also what does it sound like.

Yes does failure leave exhaust in quiet or sport mode (if sport i'll leave it broken).

You know the funny thing with these solenoids is that they are some how connected to the same harness or circuit that the engine coolant temp sensor is on. When I bought my car last August, it arrived on the truck, I drove it off and after not more than 2KM my temp sensor quit.

I had it replaced under warranty and it failed again a few days later. The dealer ended up calling for support (not sure where) and they tracked it down to one of the exhaust solenoids being on the same circuit. I think ultimately the solenoid failure was due to a vacuum leak...

I thought it sounded fairly loud when I first got it not really having been around these cars much before, and it had a sharky bypass so thought maybe thatsj ust how it sounded. So much quieter after the solenoids were replaced!

Never would have guessed an exhuast solenoid would keep blowing the temp sensor though.

If you plan to leave them 'broken' then beware that it can affect more than just the sound of the exhaust.

My port side was stuck open. The problem with leaving it broken is that only one side was open. This resulted in a rather raspy, not pleasant exhaust note. Luckily, they're easy to replace. I'll take a picture of the bad solenoid to show the damage that an otherwise inconsequential driveway scrape can cause.
