I purchased a new 2017 Tesla Model 3 in late 2017, drove it 135k miles and suddenly had issues with the battery cooling fan staying on all the time and the interior cooling not working. The Tesla service center found the condenser completely blocked with road debris. This was possible because of a design flaw in the condenser being horizontal and receiving unfiltered air directly scooped from the vent below the grill of the car. This design flaw is present in all Model 3 and model y as I can see but, the amount of debris scooped depends on many factors such as mileage, geography, highway vs local, etc. The result was damage costing $4k to repair and no way of preventing the design flaw from causing another failure in the future.
I am writing to file a formal safety complaint against Tesla, inc. Regarding a software update failure that has disabled legally required vehicle functions on my Tesla for over two years. For more than 26 months, my vehicle has been unable to complete a software update through Tesla's over-the-air (ota) update system. As a direct result of this failure, my vehicle's display screen does not function for the first several minutes of every drive. This prevents me from accessing my speedometer, turn signals, and other legally required safety features, rendering the vehicle non-compliant with federal and state motor vehicle safety standards during this period. I have made multiple documented attempts to resolve this issue through Tesla's customer support channels over the course of these two years. Despite these efforts, the issue remains unresolved. Tesla has now informed me that resolving the defect will require a paid service visit — despite the fact that the failure originates within Tesla's own software update infrastructure, not from any action or negligence on my part. I am requesting that NHTSA investigate this matter on the following grounds: 1. The software defect disables legally required vehicle safety functions, including the speedometer, turn signals, hazard lights, and more. 2. The defect has persisted for over two years despite repeated good-faith efforts by the vehicle owner to resolve it through the manufacturer. 3. Tesla's ota update system is manufacturer-controlled infrastructure. A failure within that system constitutes a manufacturer defect, not a maintenance issue. 4. Tesla is requiring payment from the consumer to correct a defect in their own systems. I believe this issue may not be isolated to my vehicle and could affect other Tesla owners experiencing similar ota update failures. I respectfully request that NHTSA investigate whether a broader safety defect exists and whether a recall or corrective action is warranted.
I had just finished supercharging my vehicle from 50% to 80% and when I entered the car to drive home two warnings showed up 1. Steering assist was reduced and it might be more difficult to drive; and 2. Lane departure avoidance warning was not working. I did a hard reset twice - (foot on the brake while pressing the two steering wheel 'wheels') and began driving the 10-15 minute home. After an incredibly scary and difficult drive down a circular driveway, and great difficulty turning the wheel to make a right turn in one try, I picked the straightest route to my home - stopping one more time to hard reset. Again nothing! luckily there was no traffic but I had to make 9 ninety degree turns to get there. I got home - taking 4 tries to maneuver the car into my driveway and garage. I left the car in the garage. Tesla service was closed for the weekend so I arranged for a tow on Monday. The next (Sunday) morning I did another reset and this time the steering assist worked, and I have to assume the lane departure avoidance was working as well because I only drove around the block and put it back in the garage. I understand other models of Tesla have been recalled for this very issue and I'm wondering why the Model 3 was not recalled as well since the software is the same is it not? I don't know if there was something wrong with the supercharger that created the problem.
Feb 25 around 4pm pt we were driving north on us hwy 101 using the basic cruise control feature of our Model 3. Based on our settings I believe this would be considered adaptive cruise control, but I'm not sure. Enhanced auto-pilot was not in use. On a largely open highway, in particular with no one in front of us, and thankfully, no one close behind us, the car suddenly started to lose speed, not brake, just lose speed. I pressed the right-hand button on the steering wheel and called out "report bug" so there should be an incident record with Tesla I believe. After letting it slow a bit, I pressed the accelerator to resume and it resumed speed ok. I have used the "report bug" several times on this issue so there should be records of other incidents. Feb. 26, around noon. Traveling on central expwy at 55, the car suddenly slowed to about 25 in the space of a few seconds before re-accelerating. No visible object to cause this. Thankfully, no one behind me which is why I let it drop speed to see what it would do. Again, this was using cc, not eap. This first happened on Jan 14, '22 using cc on s-bd us 101. I have video of this, but it's 19mb, so can't upload. I took to Tesla service and they concluded it was moisture obstructing camera view. Made no sense then as you would it expect to occur constantly, not intermittently. Presumably if this was a vacuum issue, they would have checked that. I think the 3 works cc by wire.
My rear glass cracked. However, there was no damage to suggest an impact of any sort. I looked carefully and saw there was no damage to suggest this was caused by an impact. I took the car to the Tesla dealership and they also examined the glass and agreed that there was no impact of any sort that would have caused the glass to crack. They then told me that they have seen this on multiple Tesla vehicles and believe it's a manufacturing defect possibly related to the defroster. They refused to cover it under any warranty as I was out of the warranty period.
