2015 TESLA MODEL S Complaints

I had been driving in the rain and the battery got wet. This was found to be due to corroded umbrella valves which allowed water to get in. The car had not been submerged or in deep water, simple driving on the interstate. The car gave me a warning "Service is required-car may not restart." I started out for the service center and the car failed after 65 miles. I thankfully was in a safe place when it happened. I had to be towed from Portland, Maine to Londonderry, NH for service. The umbrella valves were replaced at my cost $1,871.12). The umbrella valve problem is occurring on many models and Tesla is repairing them on the newer models, free of charge. They are not calling it a recall (it's a Service Notice) but I think I should be reimbursed for the repair since they should repair this potentially dangerous problem on all models, not just newer models.

My 2015 tesla model with less than 55000 mi had the front suspension broke on [XXX] when i pull out of the driveway. I heard a hard noise from passenger front tire that is scraping on the fender liner.The car was not drivable and had to be towed to a tesla dealership in cherry hill NJ > Quoted bill is $1800 to replace. With the low mileage , I never expected the suspension to brake unless there is a defect on the cars manufacturer front suspension fore link. I read on the NSHTSA that there was an investigation for the several complain for the 2015 - 2017 tesla model S . The service car representative took a picture of the broken suspension fore link that is holding the suspension front tires. I forgot to ask him to forward the picture to me.Maybe I can ask him when I pick up the car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

was driving Tesla when warning light appeared “ charging declined “ . drove car home battery no longer charging . Tesla stopped working after only 68,000 miles . Tesla wanted $15000 to replace the battery more than the car is worth.

An investigation has been conducted into a persistent and widespread defect affecting the 2015 Tesla Model S and other early models equipped with the first-generation Media Control Unit (MCU1). This defect manifests as the physical degradation and spontaneous leakage of a sticky adhesive substance from the edges of the vehicle's central infotainment screen and instrument cluster. The leaking substance is not merely a cosmetic issue but presents a credible safety risk to vehicle occupants and the vehicle itself. The substance is a source of Volatile Organic Compounds (VOCs), a class of chemicals with a low boiling point that are known to off-gas into the ambient air, a problem exacerbated by high temperatures. Exposure to these compounds can lead to both acute and long-term health consequences, including respiratory irritation, headaches, and in some cases, serious chronic illnesses. Furthermore, the presence of flammable solvents and components within the adhesive, combined with the heat generated by the electronic components of the MCU1, creates a potential fire risk. This report is submitted to the NHTSA to provide a detailed, technical analysis of the adhesive degradation and leakage in the 2015 Tesla Model S. The purpose is to formally document this specific defect as a safety issue that warrants regulatory action, separate from but related to the manufacturer's previous recall for the MCU1's eMMC memory wear. It is essential to demonstrate that the adhesive failure is not a cosmetic inconvenience but a distinct material failure with serious implications for occupant health and vehicle safety. This report aims to provide the necessary evidence and analysis to support a formal investigation and a comprehensive recall that fully addresses this physical defect.

What happened? While driving my 2015 Tesla Model S, the main touchscreen (MCU) began intermittently going black, disabling access to essential vehicle controls, navigation, climate settings, and rear-view camera display. At times when the MCU was functioning, the rear-view camera feed would still display a black screen upon shifting into Reverse, leaving me without any rear visibility. Component or system that failed: Media Control Unit (MCU1) / eMMC memory failure Rear-view camera and/or associated wiring harness Safety risk: The intermittent blackouts of the MCU and loss of rear camera feed created significant safety hazards, especially when reversing or attempting to adjust driving settings while in motion. The loss of rear visibility increased the risk of collision with pedestrians, cyclists, or obstacles. The MCU failure also limited access to defrost/defog controls and turn signal audio feedback. Problem reproduction and confirmation: Tesla Service has confirmed both the MCU1 hardware failure and the rear-view camera malfunction. The problems occurred repeatedly before being inspected. Inspection: The vehicle has been inspected by Tesla Service Center technicians, who diagnosed both the failing MCU1 and the defective rear-view camera. Warning messages or symptoms prior to failure: For MCU: slow system performance, frozen screen, then intermittent complete blackouts while driving. For rear-view camera: black or distorted camera feed when in Reverse, even when the MCU display was otherwise operational. These issues began occurring in June 2025 and became progressively worse until Tesla inspection on July 6, 2025.

A few times the steering control has shut off while I am driving. Steering failure lasts a few seconds and then returns to normal function. The car makes a VERY loud alarm sound when the steering is inoperable. I have not seen any failure messages on the screen or in the Service menu. I took the car to Tesla for service yesterday. They did some sort of remote scan of the fault codes and told me that there is nothing wrong. They told me to continue to drive the car and record when the steering stops working again. This sounds like ridiculously bad advice to me. While the steering control has always returned in just a few seconds, that does not mean that it will in any future failure. I am concerned about driving this car. Tesla wants $275 an hour to investigate the problem, which also seems ridiculous to me. I have seen that there has been a recall for similar problems in newer Tesla Model S vehicles. It seems logical to me that these problems may be related and deserve additional investigation ... at Tesla's expense.

Many air bubbles are appearing towards the bottom of the instrument panel on our 2015 Tesla Model S. This started a couple of weeks ago and the bubbles are increasing in size and number and they are moving upwards. The bubbles don’t presently obscure important driver information such as the transmission mode (drive, park, reverse, neutral), remaining battery range (e.g. 80%), car speed (mph), parking sensor distance, brake light status, car door open, frunk open, tailgate open, time, outdoor temperature, car lights on/off, warning lights, etc. However, the bubbles likely will do so in the future. Much of this information is vital for safe driving (e.g. transmission mode, speed (mph), remaining battery range, brake light status, and warning lights). As such this display should be replaced by Tesla at nominal or no charge to the owner. According to the internet, the cause of these air bubbles is a failed seal around the instrument cluster that allows a lamination fluid between the LCD display and the cover glass to leak out. It is a very common problem with older Model S’s. It is a critical safety problem.

Large drive unit that has previously been replaced by Tesla failed due to coolant ingress leaking through rotor seal. Known issue per 3rd party technicians.

Hi, my trunk won't open when I press the button. This is the second occurrence that jas happend. When inside the trunk compartment the emergency cable to open the trunk is also not responsive and can not open the trunk. I think this is a big safety concern as the safety cord is there for a reason and in both cases id did not worked.

Steering: While driving today (7/5/2025), all of a sudden and without warning, "driver assist" (power steering) became disabled. Steering wheel immediately became heavy in the sense that it was extremely difficult to turn. Motor: Also, on 02/22/2024, while driving on the freeway at freeway speed, all of a sudden and without warning, the rear LDU (large drive unit) failed and the car became inoperable. At that time, the car had approximately 45k miles on it.
