Vehicle has 51,126 mi as of this writing. When new (June 2020) 250 miles of freeway range was typical in typical California weather for an efficiency rating of 280 wh/mi for 100% to 1% state of charge (soc). This was tested repeatedly, numerous times, on multiple road trips. At ~12k miles into ownership, oem tires were swapped as they were dangerously useless in rain and snow. Repeated calculations confirmed ~10% range loss. This meant that average wh/mi consumption went from about ~280 wh/mi to about ~308 wh/mi, for a real world freeway range reduction to about 227 from say 250 (again 100% to 1% soc). This was expected and accepted. Last 2 years were spent in new england during which freeway range started to drop precipitously, reaching a low of 166 miles (100% to 1% state of charge; about 420 wh/mi) at freezing temperatures; verified across two identical road trips. Cold weather range was expected, but in retrospect, this was far too much of a drop. Now back in California, range has dropped even further and settled at about ~150 miles -- or an abysmal 450 wh/mi -- I. E. , a 40% drop from the oem tires, and a 34% drop from the new tires. All charging stats (and Tesla's remote tests) show the battery is at full capacity (69 kwh is a 1% to 100% recharge and the battery is rated at 70 kwh). Tesla claims no faults, and assign blame to driver (high freeway speeds; sentry mode; climate control; etc). Tesla now threatening -- as indicated in recent class action lawsuit -- to charge $275/hr if I continue to press the issue, even though I have explained rental Model Y vehicles have vastly better range. I have insisted on several options: (a) pay for a loaner to test. - no (b) I will rent another Model Y from hertz and report back with data. - no (c) acknowledge the problem, I want to pay to fix it. - no (d) acknowledge the problem, but you don't know how to fix it. - no it is clear I am now being strong-armed by their diversion team.
Without any warning, the display on my car froze up when my car came to a stop, and I could not accelerate. It seemed to say I was going 15 mph, when in fact I was stopped, and the display was completely unresponsive. Stepping on the accelerator did nothing. I could not use my turn signals, activate my 4-way flashers. No one was injured, since this happened on a quiet residential street, and I was able to wave to other motorists to go around me. After about 3 minutes, my car seemed to have reset, and I was able to drive it normally. I would gladly make my vehicle available for inspection upon request.
Heating / defrosting unit failed. While driving to work in 1 degree freezing weather my heating / defrosting unit would not provide a clear fog free windshield so I could safely see outside. Dealer has me scheduled for a date for repair but this is the second time this has happened. First time 9/2021 and now 1/2022. No inspection has happened yet. Warning message displayed saying that the climate control has failed.
Incident: car shutdown and power failure with little warning. Time/date/place of incident: 9/7/2020, approximately 5:20pm in livermore, CA. While driving at a speed of approximately 45 mph eastbound on w jack london blvd (past wolf house drive), the car's computer displayed an "unable to drive" message (error code di_a137) and instructed us to pull over. Since we were on a 2-lane road with no shoulder we proceeded to the nearest driveway (turning left to a driveway at ~1105 w jack london blvd). The car vibrated violently then shutdown. The estimated time between the initial warning and shutdown was only about 5 to 10 seconds. Other error codes/messages displayed were "power reduced" (dir_a126) and "vehicle shutting down" (di_a063). We called Tesla roadside assistance from the vehicle and were instructed to power cycle the car by having all passengers and driver exit the car, close all doors, then have the driver enter and step on the brake. We did this and the car restarted as normal. We drove home for about 45 minutes without incident, but we were obviously concerned that this could happen again, so we kept to the right lanes whenever possible and limited speed. Other information: about 20 minutes prior to this incident we had charged the vehicle at the livermore Tesla supercharger. It was also a record hot day (111 f). This is a new car purchased in July 2020 and at the time the odometer was approximately 1,300 miles. The earliest service appointment I could get is scheduled for 9/17/2020, so I do not have any additional info from Tesla on why this happened, or how this will be repaired. The service agent mentioned a firmware failure as a possible cause. We were fortunate to be able to get off the road before the car completely stopped but if this happened on a freeway, we may have been in a high speed crash with a stalled car.
