Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Car starts with ease when it's cold but it's hit or miss when engine temp is at optimal running level.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

1 acknowledgements have no verified action link; they do not establish a repair result.

My car did that at one point, and a new starter fixed the issue for me (was actually covered under CPO).

POST 1 / ORIGINAL POSTEROriginal post

Any 996 owners experience hard to start 996 despite new battery? Car starts with ease when it's cold but it's hit or miss when engine temp is at optimal running level. The challenge with starting is especially troublesomey following re-fueling or a quick stop where engine is off for a few minutes or less. The car will restart If allowed to sit for a few minutes. No issues with check engine light and I recently installed a new battery. Very perplexed.....

POST 3Original post

Possibly the voltage regulator on the alternator.

POST 4Original post

I had the same issue and after two batteries and three testing of the alternator I replaced the starter and problem solved. Pull you alternator and have it tested, if it tests good consider replacing your starter. Lot of DIY information on it.

POST 5Original post

Several people have found the power line running to the starter deteriorates over time due to heat. It's difficult to see unless you have things apart. Do a search and you should be able to kick up some information. I recall a good thread in which the poster showed the damage.

POST 6Original post

Similar issue here, turned out it was the coolant sensor.

POST 7Original post

Does it crank and just not start, or does it fail to crank?

POST 8Original post

Quotes source post: 9602753

+1. Fairly common concern, even on the 997's.

POST 9Original post

Another possibility is the crankshaft position sensor (also known as impulse sender).

POST 10 / ORIGINAL POSTEROriginal post

Wow......Lot's to consider. I'm going to go down the line of suggestions including a new starter. I'll post my progress.

POST 11Original post

Mine has also been giving me a slow start when hot. IMO it's "heat sink" on the starter. All my cables are good,and just cleaned the engine to chassis ground. I'm gonna wrap the starter with heat shield and see if it works. If it does, it's only a band-aid as the starter is prob on it's way out
