2015 Tesla Model S 70D Engine problems

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.

In 6 years the drive unit has failed and been replaced. Multiple other tesla owners report similar issue. I have a Tesla S 2015. The car will not drive or will abruptly stop driving when the drive unit fails. First incident I was driving on 55mph road and abruptly stopped. Second incident I cannot recall. Third incident tesla provided no support and the car was experiencing multiple driving failures which would turn back on to allow the car to only drive 2-7mph. Tesla reports they know it is a problem with the...

On September 7, 2021 I was driving in heavy rain conditions. The rain was so heavy I could only drive at speed of 25 mph. My car displayed a message "Car may not restart - service required" I pulled under a canopy of a gas station and put the car in PARK. The car did not restart after that and was towed to Tesla Service Center. The next day I was told that a RAPID MATE vehicle side connector failed due to water ingress and that HV battery needs to be replaced due to same damage. I was presented with a $23622.54...

Tesla has reduced the charging capacity and charge rate per: re: nhtsa action number: dp19005 - investigation subject : battery management software updates prior to this software update, the charge rate was double the shown rate.

The mcu went out. Turn signals, brake lights, backup camera, hvac controls, all went with it. Car would drive, but would not

Tl* the contact owns a 2015 tesla model s. The contact stated that there was a loud sound coming from the engine while the vehicle was plugged up and charging. The contact disconnected the charger in fear that the battery or the engine may explode. The contact stated that the vehicle failed to be fully charged. The vehicle was not diagnosed nor repaired. The manufacturer was contacted and notified of the failure. The failure mileage was 65,874.

The mcu failed while we were traveling, which basically locked the climate control, access to suspension, speed control, autopilot, navigation, radio, turn signals, and back up camera.

My 2011 chevy equinox ran out of oil in between regular oil changes due to the oil consumption issue with the incorrect sized piston rings. This escalated quickly and destroyed my timing chain which destroyed my engine.

The touchscreen in my 2015 model s has completely failed. I've attempted all of the resets that tesla recommends to restart the system to no avail. The car is nearly useless, none of the electrical features of the vehicle work, including heating/air conditioning, charging features, audio or turn signals. The car worked fine yesterday, today the screen was just gone.

With the recent news on nhtsa investigating tesla model s touchscreen unit problems, I like to add my experience for the record: on 01/31/20, my computer screen died which limited the car's functionality (e.G. No hvac, radio, bluetooth, etc). On 02/06/20, tesla came out to inspect my car, and verified I needed to replace the computer. The technician admitted how bad the problem was for productions with mcu v1 computers. But before the technician left, he performed a battery disconnect which made it worse. ...

The mcu v1 is known to fail. It's become sluggish and black screens. Not acting as it should.

Tl* the contact owns a 2015 tesla model s. The contact stated that the media control unit touch screen was inoperable. The contact stated that while attempting to recharge the battery, the system flickered and failed to charge. The contact stated that the back-up camera was also inoperable. The vehicle was undrivable. An independent mechanic went to the residence to inspect the vehicle and the contact was informed that the media control unit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 89,586.

Re: nhtsa action number: dp19005 - investigation subject : battery management software updates starting with a software update in may 2019, tesla capped the max voltage the high voltage battery would charge to. They claim they did this "out of an abundance of caution" after several non-crash fires happened to these models. Tesla took action to downgrade horsepower and range along with all other aspects of performance through a total voltage cap after claiming to be releasing a fire-safety update, but officially...

Starting with a software update in may 2019, tesla capped the max voltage the high voltage battery would charge to.

This change happened while the car was parked in my garage and...

Driving down the freeway at maximum speed limit (65) needed to remove wallet from back pocket. Unbuckled seat belt why still moving at maximum speed limit. Upon unbuckling seat belt engine immediate shut off and vehicle came to involuntary stop within approximately 5 seconds. Fortunately, the vehicle following was alert and stopped in time to avoid serious rear end accident. Very concerning if this occurs and owners are not notified of the danger we experienced.
