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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Porsche 911 Targa 4s Heritage Edition verdict →
