While driving 40 miles per hour a sudden explosion happened with no warning. Thought it was the engine due to the smoke coming out of rear of the vehicle but realized that engine was still on and steam was coming out. All coolant drained out of vehicle and on road. Vehicle was towed to a Porsche dealership in Duluth Ga. The coolant tank exploded causing minor body damage and sudden loss of all coolant. The dealer replaced the shattered coolant tank but found no cause as to why the pressure got so high to cause the tank to explode. INFORMATION R…

THE CARS AUTO IDLE OFF FUNCTION THAT SAVES FUEL BY TURNING THE ENGINE OFF AT STOP SIGNS AND LIGHTS IN INOPERATIVE. I HAVE HAD IT INTO MULTIPLE DEALERS 4 TIMES SINCE 12/2020 WITH THE COMPLAINT. IN MY OPINION THERE IS A TEMPERATURE SENSOR THAT IS MALFUNCTIONING AND NOT ALLOWING THE CAR TO GO INTO THE FUEL SAVING MODE. I AM TOLD THAT THEY ARE NOT ABLE TO MAKE THIS FUNCTION WORK PROPERLY. WASN'T THE CAR CERTIFIED FOR EMISSIONS AND FUEL ECONOMY WITH THIS FUNCTION IN PLACE?

Heard a ticking noise while driving. Pulled over, on freeway. It was not a safe situation parked on side of a major freeway. Turned off car to look around the engine and found nothing. Started the car again and it died within 5 seconds. The electric system completely died after and would not crank. Got it towed to dealer after waiting for tow truck 3 hours. I was really scared sitting in my that someone would crash into me. Dealer has now the engine apart diagnosing it. It is a failed engine and will need a brand new motor.

1. Door panel Issue. I have a 2012 911, and have noticed last year that the door panels have popped up on both sides, it looks like the glue has given way. It seems that this is a common issue for Porsche 911. 2. Keyless Entry Issue. I was not able to lock my car by pressing by the door handle's button. I was able to unlock the car. I then tried on the passenger's side and was able to lock it. It's been going on for months, and every time it occurs I will have to spend minutes to get into the car.

My air conditioner/heater fan does not come on after car has been sitting for a few days in a humid climate. This problem is documented with a temporary fix on the static.nhsta.gov site. https://static.nhtsa.gov/odi/tsbs/2021/MC-10186302-0001.pdf The problem is it happens to me every week or so. There is no permanent fix. This is a safety issue because without the fan motor the defroster doesn't work and the windows can fog up creating a dangerous situation.

COMPONENT THAT FAILED: A high-pressure fuel injector (cylinder 2). The failed injector and engine wiring harness are available for inspection on request. The vehicle is currently at an authorized dealer. WHAT HAPPENED: While driving at approximately 35-45 mph under light throttle in normal traffic, the engine began misfiring without warning. The misfire worsened rapidly over several seconds and the engine ran roughly enough that I pulled off the road. A strong burning smell was present immediately afterward. The vehicle has continued to misfir…

Two separate instances of fuel line failure and fuel leak in the engine compartment. The first in March 2024 and the second in September 2025. The situations both resulted in fuel leaking on top of the hot engine components. Repair requires removal of the engine and transmission. In 2024 repair time was 9 weeks, in 2025 - 3 weeks. In the first case service was covered under warranty, the second partially covered by extended warranty. Repair costs approximately $6,000 per occasion. Leaking fuel on a hot engine clearly created an unacceptable haz…

Woke up one morning and noticed a very strong gas smell coming from the car while driving with the windows down, even at low speed. Once I noticed the smell I stopped driving and exited the vehicle and again noted the very strong smell. I immediately took the car to the nearest Porsche service dealership in Beverly Hills. The repair was covered by warranty, and the issue was found to be due to a leakage from the fuel supply line that runs from the fuel tank to the engine. This is a very serious issue that I find dangerous had I not immediately …

Cruising on the highway and a transmission error comes up saying that there's no reverse gear. Got off the highway and even gears aren't engaring, no 2,4,6 gears. 1,3,5,7 gears are engaging. Turned off and parked the car for about an hour. Turned it on car drove fine but start/stop wasn't available and sport modes are not available. Had the car diagnosed at the dealer and the same symptoms and codes are exactly as SB-10054511-7606. The 2012 model year needs to be included.

On XXX, less than 24 hours after an authorized Porsche dealer released this 2024 911 as a successfully completed repair with the diagnostic codes cleared and no root cause documented, the vehicle suddenly lost motive power while traveling at highway speed. It entered limp mode with severe deceleration and displayed a red engine control error, forcing an emergency lane change across traffic to reach a parking lot. After stopping, an active and significant fluid leak was observed trailing from the engine compartment, creating a fire risk. The 12-…

The door panels at the top wrap on my 2013 Porsche 911 and I understand this is a problem on Porsches 911 delivered between 2012 - 2019 A number of recommendations have been made for owners to glue the panel. This panel is designed to release in a side impact condition and any glue modifications to this panel would violate the designed operation. The manufacture is well aware of this issue and has replaced a number of them out of warranty for free, but you have to back them in a corner.

Both driver and passenger side door panels are failing causing them to raise due to failed seal and/or glue used in production. This has been inspected by the Porsche dealer and has been deemed a failure from the factory. This issue has caused for not only visibility issues and accessibility to door locks and windows, but could potentially impact the functionality and safety of the overall side airbag operation. This is a known issue based on the responses I have received from the dealership and Porsche factory representatives on the model 9…

Spoiler lift spring brackets on both sides are broken allowing the springs to get in the way of the normal performance of the spoiler. This could impede the deployment of the spoiler or the successful retraction of the spoiler, creating a reduction in downforce (grip) or creating a safety hazard of a non-fully retracted spoiler. This was identified by a third-party repair shop during maintenance work. In doing further research online I have determined that this is an extremely common issue on this model generation (991.1) that Porsche will n…

I am writing to express my significant frustration regarding the handling of NHTSA Recall 25V896. I dropped off my vehicle several weeks ago following the recall notice, only to be informed later that the software remedy is not expected until Q2 2026. It is unacceptable to request that customers surrender their vehicles for a recall when the manufacturer is not yet prepared to provide the necessary service or solution.

Tail light fall off the car while driving, catching it dangling from the car holding by only one wire. Upon inspection, they came off due to a broken plastic lug that was holding the taillights together. It appears that Porsche changed the taillight mounting design in the 991 after the 2013 model year, adding a metal piece to keep it together even after the plastic cracks, melts, or fails. Mine is 2012 so it will cost us a fortune for get it fixed, for something it was clearly a design failure from the beginning.

The tail light assembly mounting fastener failed and the tail light assembly fell out of the rear bumper assembly. There was no indication of a failure while driving. Apparently this is a known issue with the 991.1 version of the 911.

Both my rear break lights are showing stress cracks from movement of the frame of the body. There are other references to this happening online from other owners and it's a manufacturer defect. I brought to the dealer and was told that they should be replaced for $3000 each as they are allowing water to intrude and will cause a shorting out of the brake lights. No brake lights would be a major hazard. The cracks in both lights were not due to impacts. It is a design issue.
