Should You Buy the 2020 Porsche 911?

Reliability standing is good, and this year sits in the middle of the 911 lineup. It is the first year of the 992 generation. The 2019 rates better, with fewer complaints and only one recall. The 2021 rates about the same but drops to mixed reliability.

Owners filed just 3 complaints. The one with a mileage attached is a seat release failure, reported in the first 10 miles. The bigger story is recalls. Federal records list seven, covering the power train (two), back over prevention, visibility, hydraulic service brakes, suspension, exterior lighting, and structure. Repair costs run high too. Independent data puts yearly repair spending for the 911 at $1072, against $739 for its class.

Ask the seller for proof that all seven recalls were completed, especially the brake, suspension, and power train ones. Have the seat release checked. If you want fewer recalls on record, look at the 2019 first.

Compared to the 2021 Porsche 911, which scored 2 points lower. See also the 2019 Porsche 911 for an earlier comparison.

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.

SEATS

1 complaint

2020-05-01

The contact owns a 2020 Porsche 911 Carrera. The contact stated that the driver’s and passenger’s seat release straps failed to operate as intended to allow passengers in the rear of the vehicle to enter or exit as needed. The vehicle was taken to a dealer where it was diagnosed and determined that unknown parts needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 10.

MY 2020 PORSCHE 911 WAS TWO DAYS OLD WHEN I GET A "IGNITION LOCK ERROR-SERVICE REQUIRED". THE NEXT DAY THE TACHOMETER STOPPED WORKING. AFTER THE DEALER FIXED THE PROBLEM, I DROVE HOME AND PARK THE CAR FOR TWO DAYS. THE NEXT DAY THE CAR WOULD NOT START. I WAS TOLD BY THE DEALER THIS CAR HAS MANY PROBLEMS WITH IT'S COMPUTER WHICH MAKES THE CAR UNSAFE BECAUSE LOTS OF ITS FUNCTIONS ARE COMPUTER CONTROLLED. I ALSO JUST RECEIVED A RECALL NO.19V-878.

There is a fuel line above the engine that is leaking fuel onto the top of the engine and running down to the exhaust components. Car is giving off a very strong gas smell. Brought it to Porsche Jacksonville and they are replacing the fuel line above the engine. They have to pull the engine to do so. No warning messages at all, just a strong gas smell. You can pull the rear engine cover and look into the engine bay and find the fuel on top of the engine, or brownish discoloring from fuel.
