Hi, I would like to seek opinion on how to proceed with my FWD issue. Background information: I took delivery in late September 2016. On my delivery day the driver side FWD failed (it scraped the quarter glass trim), so the DC took it back and gave me loaner. It was repaired and driven back to me. Not a good delivery experience but that's that. Around February 2017, my driver side FWD started to detect phantom object in extremely close proximity (red line next to the door). Obviously when this occurs my driver side door will only open few inches only. It has progressively gotten worse since then. For example, I can't even open the driver side FWD with the FOB, it would just "beep beep beep". I cannot open it via the touchscreen either. The only way to open it is to physically push on the door handle, and then it would open few inches requiring an override if I want it to open more. I've finally attributed to high heat under the sun because every time it occurred the driver side FWD was facing the sun directly. Service center information: In April I've finally got enough of this so I took it in local SC to fix this and other issues. They've replaced the sensors and that was it. Corrections: Door Trim General Diagnosis Perform inspection of vehicle logs for diagnostic trouble codes or alerts. Inspection revealed ultrasonic sensors required insulation for proper operation. Corrections: Replace Rear Door Ultrasonic Sensors I continued to have the same issue so I took it again. Corrections: Sensor - Ultrasonic - Rear Door - LH Perform removal and replacement of ultrasonic sensor assembly for drivers rear door. Tested and is now operating as designed. Ok so I went to pick up the car. I had to transfer the stuff from loaner back to my car and guess what, the FWD faulted right there. I couldn't even open it. I called the tech over and have them witness it. He said it could be from reflection of the wall. Bring it in again if it happens again and will get engineering involved. So 3rd time's a chime? Corrections: Sensor - Ultrasonic - Rear Door - LH Perform review of vehicle logs for diagnostic trouble codes or alerts. Inspect ultrasonic sensors for proper reading and communication. Performed removal and replacement of 2 ultrasonic sensors along with installation of foam tape. Tested after repairs and is now operating as designed. Nope, still happened. What happened to getting engineering involved? Finally, 4th attempt: Corrections: Door Trim General Diagnosis Performed inspection on rear door ultrasonic sensor. Inspection revealed ultrasonic sensor and tripod replacement recommended. Corrections: Sensor - Ultrasonic - Rear Door - LH Perform removal and replacement of ultrasonic sensor on drivers rear falcon door along with tripod assembly. Per engineering department replace all pads for falcon door assembly. Updated firmware for vehicle. Left vehicle out in heat for 2 consecutive days under various temperature conditions with no faults in detecting false objects. Vehicle falcon door is operating as designed. They kept the car for 2 weeks this time. They finally got engineering involved. The advisor was saying they might need to get the whole door replaced but need approval. Instead of replacing the door engineering told them to replace tripod assembly and all the seals etc. They kept the car for more days since it's not always replicable as it needs sunny day and high temperature. It doesn't happen on cloudy day. They know my issue alright. Finally SC called to say it no longer produces fault and they checked the temperature on the door (120F or so?). I took the car back and it has worked much better. I think there were still once or twice where a less severe fault happened (gray line next to door, not red, with nothing on the side, parked under the sun). I didn't pay much attention to that as it wasn't severe. Current state: Fast forward to October 2017. I took my kids to the library with a roof top parking. It was 10AM and the outside temperature was about 90F. There was no car next to the driver side at the time. The FWD fully opened at this point. When I returned to the car, I opened the driver FWD with the FOB. There was no car on the side and it only opened half way. I said to myself, oh no not again... needless to say the dreaded phantom object detection came back. The line is there on the screen. It didn't go away until I drove for 5 minutes. I immediately sent an email to SC, the advisor, and Tesla support asking for next step of action. I have not heard back from anyone. Today my wife took the kids to the same library and she told me the driver FWD only opened half way again when they got off the car, again with no car on the side. Question: Do I ask Tesla for a replacement? Do I file the lemon law? I've given them 4 tries and according to California Lemon law, it's already a lemon with 4 attempts on the same issue. Besides this dreaded FWD fault I am happy with the car, but I can't live with this fault for the next X years as it could potentially be dangerous if I need to unload my kids in an emergency situation. Not to mention the inconvenience this is causing me whenever I use the FWD. I am also worried as the weather is getting cooler in the coming months they will just tell me there's no issue. I don't know if I will put myself in a disadvantageous position if I wait til next year where I imagine the problem is more easily replicable in summer. Thanks in advance.
