My daughter went to pick up my 2018 boxster (with 10k on it), after less than a mile drive she called to report smoke coming out the vehicle. She called the dealership and the salesperson came to drive the car back to their lot. After a day they reported that everything is fine. My son got the car back to his sister who still noticed the smell from the previous incident. However, after a return visit to the dealership, the technician said everything is OK. We decided to have someone drive the car and bring it to Columbia from Houston, TX. After driving through north Texas and part of the Oklahoma , (in Tulsa) the clutch gave up with no resistance. Now the dealership that sold the car to my wife doesn't even want help pay for the tear down to figure out the cause of this problem. They are informing us that they were 13 Revs, whatever that is, and will not do anything to help. Can you please help me figure out a course of action? I don't know what to do. Thanks in advance.

Maybe 13 over-revs? Meaning rpm’s exceeded redline, which could certainly destroy a clutch. The dealership can run a DME report and get that information from the computer.

how could RPMs themselves destroy a clutch? redlining in gear i don't think would affect the clutch adversely. conversely, reving even below redline and dumping the clutch could destroy the clutch.

 

[Pavanseth]

Is the car pdk? If so it should covered under warranty. If not, dealer could argue that the clutch was ridden causing wear and failure.

 

[jimmuller]

smoke = burning clutch disk? Could be. Could a fluid of some sort have sprayed or dripped into the clutch?

 

[socablo]

Thank you for the feedback. At this point the dealership in Tulsa doesn't know the cause. They will be doing a tear down to check. It is the dealership in Houston that is hanging their hats on Rev count. This vehicle was purchased three weeks ago. To my knowledge the vehicle is not pdk.

Hummm. I don't mean to be rude, but how could you have bought a car without knowing whether it is a manual or pdk? I'm curious.

Gentlemen, @socablo lives in Columbia, MO and just purchased this car for his wife from a dealer in Houston; he posted in the New Members forum. Let's cut him some slack and help him out, OK?

Some questions:
- Did you buy the car new or used? IIRC, you just bought the car for your wife, and the dealer in Houston is where you bought it from.
- If used, was the car CPO (Certified Pre-Owned) by the dealer?
- Does the car have a manual transmission or an automatic transmission?
- Who has driven the car regularly since you purchased it? Sounds like only your son and daughter? Are they both proficient with driving a manual-transmission car?

I know this next thing is hard for a father to do with offspring that he trusts, but you need honesty regarding how your daughter (and, to a lesser extent, your son) have driven the car. If there were a lot of over-revs on that engine before it was sold to you, it would not have passed the CPO certification process unless the dealer itself is fudging that process -- which means the over-revs occurred after that certification.

I would have the Tulsa dealer verify that the over-revs are on the car's ECU -- it's operational computer, if you will. If possible (not sure the ECU logs this), but have the Tulsa dealer note dates of occurrence of the over-revs. That bit of data will be telling regarding who caused the issue.

Good luck, and keep us up to date.

My wife can drive both manual and auto, however, most folks have a strong preference one way or the other. I'd want to get my wife what she wanted in terms of a transmission, especially at this price point, but that's just me. I can't wait to hear the rest of the story and I hope this gets resolved for him/his wife quickly! I'm sure his wife will be surprised and elated, regardless. BTW, it is used with 10K miles. Yes, please keep us posted!

Overrevs would pretty much indicate a manual trans. Even one overrev from down shifting into the wrong gear can destroy a clutch in short order, not to mention causing engine or trans damage. They don't call them the money shift for nothing.

 

[socablo]

My wife bought the car for me. I was not involved in the process. It was a gift as I indicated in my introduction to the forum.

My mistake; got that juxtaposed from your New Members post.

Nevertheless: If I were you, the information I would need the most is when those over-revs occurred. That will almost certainly red-flag whoever's liable for the car's current condition. Ask the Tulsa dealer to help you determine that. Thankfully, you've got the car at a dealer without potential culpability, so you should receive a straight answer from it.

 

[socablo]

My son and daughter can both drive manual. The vehicle was bought used with 10, 500 miles on it. The count according to the Houston dealer was one on April 8. The folks in Tulsa have not sent it their report yet.
The bottom line is that I have conflicting opinions from the two dealerships. Tulsa is not sure of the cause before a tear down and Houston is certain it is the Rev. I will find out more from Tulsa by Tuesday at the latest.
Thanks everyone for engaging my post.

 

[socablo]

Here is the report from Houston.

On my previous 987 you could figure out when the over-revs happened as they were stored with the number of hours then engine had been run at the point the over-rev occurred. The total number of hours the engine had been run were also stored. So you'd be able to get a pretty good idea of when the over-rev happened. I assume the 718 would have at least this level of detail for its over-rev recording.

Looks like that's what @socablo has from the Houston dealer in the post just previous to yours. Interesting that the five over-rev instances after the initial ones don't have an hours-mileage tag. I wonder if that's because they all happened at once?

I'd compare that Houston report with whatever the Tulsa dealer comes back with. The Houston report's mileage translates to 10,397 miles, though it doesn't indicate if that's the mileage at which the over-revs occurred or when the report was generated. That said, the 224 hours that the engine had been run corresponds to that mileage if the average speed is about 46.4 MPH. That seems high to me, and is an indication that the car has mostly highway miles on it.

 

[trusted]

He had one (1) range 1 over rev at operating hour 223 and change. Nothing in range 2-6. That is totally and completely normal. Technically over rev range 1 is not even an over rev because it just indicates hitting the rev limiter. I'd ask the dealer if they think I'm stupid or if they are stupid? Don't go back there and let the other dealership figure it out. Over revs are not the cause of your clutch issue.


Good luck

Over-reving causes excessive friction and creates a lot of heat and tension in between the clutch plate and flywheel- beyond what the clutch is rated for.

 

[Porsche2018]

Agree with @trusted.

I would love to buy a preowned Porsche but I always get cold feet before pulling the trigger because the history is always a big question mark. After I dropped off my 2019 3RS with 3500 miles the general sales manager drove the car for another 500 miles and I can only imagine what he may or may not have done. The 3RS when I dropped it off was broken in properly and absolutely never tracked but after that your guess is as good as mine.

 

[RotorOver]

Over revs are not the cause of your clutch issue.

This report was from the Houston dealership he picked the car up from not the dealership in Tulsa that saw the car after the issue began. We can infer the issue occurred after this DME report.
