If the local dealer is prepared to replace the AC compressor and the fan, that's a big bonus. Parts and labor puts that job at over $2 grand. And the replacement compressor will be a newer version that hasn't been prone to heat-failure.
Third party reporting agencies provide limited, basic info, only what the insurance agencies provide to them, and any online shared maintenance databases. A lot can and will be left out. Case in point, when we sold my daughter's car for her, I printed out the Carfax to provide prospective buyers. The report indicated that the car had never been in an accident. It actually had been rear-ended by a drunk driver on the freeway, causing over $6,000 in damage. Not a peep on the report. Intrigued, I ran a carfax on our old Jeep Cherokee, which had been T-boned by a red-light runner - $8,000 in repairs. Again, nothing at all on the Carfax. I have the carfax on all the service done on my i3 since 'new'. I also was able to print out the actual BMW Dealer service records on the i3, from the Connected App, before they 'improved' the app and locked that feature out. About a third of the service visits on the BMW service database are missing from the Carfax report.
One other thing can damage an i3 battery pack - leaving it parked for an extended period of time with an almost flat HV battery. So much so, that if you drive and deplete the battery, when you get close to the bottom of the charge, the car throws up a warning to change the HV battery as soon as possible.
But since you have a 30 day warranty - put it through a week of drive/charge cycles, and see what's up with the car. If the mileage in the guessometer stays low, worth a shot at getting BMW to evaluate the HV battery pack - could be a couple of dead cells in the pack that need to be replaced, BMW will charge around $300 to do the test. If the battery fails, they rescind the charge.
