Power Steering Failed Problems of Tesla Model S

At ~5,000 total vehicle miles, our 2019 Model S performance had sudden and complete power steering assist failure at highway speeds, possibly concurrent with autopilot (autosteer) failure. Either I, or the autopilot system, turned off the autopilot feature at or near a slight curve on an interstate freeway. Immediate "startle" reaction was that the autopilot feature was "fighting" me for control as I turned the steering wheel to keep the car on the freeway, with extreme effort. The reality is most likely that this "fighting" was only the immediate impression caused by the massive amount of effort required to turn the steering wheel, despite being at speeds in the 60-70 mph range. Soon noted a scrolling series of warning messages: a. "steering assist reduced: steering may require increased effort. " [which is a gross understatement. ] b. "autopilot safety/convenience features unavailable: features may be restored on next drive. " [which, after the car had sat parked for ~30 minutes, were restored. ] user-visible mcu-display failure log revealed the following supplemental failure codes (with the probable times of failure):: 1. 17:26/app_w207: autosteer temporarily unavailable 2. 17:20/app_w264 autopilot safety/convenience features unavailable: features may be restored on next drive I feel very strongly that this sort of power steering failure would likely have resulted in a less experienced driver suspecting the steering had "locked up" and be causal to a major accident. Given the circumstances of the failure mode, and at these speeds, fatalities could be likely. Of note, this is at least the fourth time this has occurred to us, but the first with this car; all other events were in a 2017 Model S performance, also at very low total mileage. After a failed repair attempt, that Model S was traded in to Tesla for this Model S . . . .

Earlier today I sent in a complaint about steering rack/power steering qassembly failure. I made an error on the Tesla service bulletin #. It should have read correctly:sb-18-32-002 r3 January 11, 2019 (not sb-18-21-003) my error was in suggesting the TSB last 3 digits changed from 001, 002, and 003. They are actually all sb-18-32-002 r1 (and r2, and r3) sb-18-32-002 r3 January 11, 2019 the final TSB has vertical lines on the left margin to identify the revised note sentence. Additionally, I erred in the bulletin changing from 18 pages to 38 pages. All were in fact 18 pages. Revisions on sb-18-32-002 r3 were notated with a vertical line in the left margin. Please add this information to my complaint. Also, I can forward a copy of the email sent to Tesla on this issue, that was not answered by Tesla.

During all electrical fault failures the vehicle was stationary. I've had 6 service visits related to electrical faults causing mechanical failures. The steering rack failure was the most recent problem. Tesla replaced the entire steering rack. The Tesla owner's forum and Teslamotorsclub. Com owners say they've replaced only the steering motor and that 1 part fixes the power steering fault. The electrical charging port failed because of electrical faults. The 12-volt battery has failed twice during the last year. 5 door regulators have been replaced in the front 2 seats due to electrical faults. 3 window regulators have been replaced due to electrical faults. The power steering failed due to an electrical fault. I've paid $6,500 for electrical faults during the last year. The tires I buy are rated to 55,000 miles, but they keep wearing out unevenly, and often blowing out, at less than 30,000 miles. The service center cannot tell me why the tires are continually blowing out and wearing out unevenly after minimal use. I went to a Tesla service center for help resetting my touchscreen and installing a firmware update when I was thousands of miles from home. The service center forced me to get nearly $2,000 of new regulators. Parts were incorrectly replaced that were not malfunctioning. Parts that malfunctioned once or twice were replaced. Parts that were replaced the previous month, and were covered under the Tesla parts warranty, were replaced again. The battery pack that powers the vehicle instantly lost 50-miles of range, 16% of total available range after visiting a service center. During 5. 6-years of ownership, I lost less than 7% of total available range. I paid a $10,000 upgrade for range. I'm concerned it's a fault or that my vehicle was damaged or the battery was replaced with a defective battery without my knowledge.

Intermittent loss of electric power steering assist, leaving the steering wheel almost immobile, and very hazardous driving under the wrong circumstances. The problem started after an over-the-air software update from Tesla. Car has 33k miles on it. Tesla service says not their problem, please have it towed here (90 miles) and pay us to look at it. Power steering rack itself failed one year ago and was replaced under recall.

There is a thread running on Tesla motors club forum in which at least 5 different owners report that their steering box has completely fallen apart. Https://teslamotorsclub. Com/tmc/threads/power-steering-falling-apart. 100951/page-3 the latest complaint from an owner provides detailed pictures that show snapped bolts and damage to the steering box making it unsafe to drive. This particular owner lives in canada and has tried unsuccessfully to file a complaint with the canadian authorities. Here is a link to more photographs posted by that owner. . Read more...
