2021 TESLA MODEL Y Complaints

5YJYGDEE2MF161659 VIN 2021 Tesla Model Y AWD with basis cruise control This last weekend we drove from our home in Arroyo Grande CA to the Mammoth Lakes area. Enroute, we experienced a number of unneeded emergency braking events while on the highways at speed (65-72 mph). While this happened about a dozen time, 5-6 of them were significant slow downs and could have caused us to be rear ended. In none of these events was there any reason for the emergency braking. One happened when another car was approaching from the rear quickly to pass. These events led us to stop using the cruise control entirely for the last 2 hours of our trip home. I have not yet contacted Tesla about this which I will be doing right after I submit this report. Prior to this, the adaptive cruise control had functioned normally with very few unexpected emergency braking events in the last year or so. We did disable the feature of “automatic emergency breaking” but that had no effect at all. This is a serious issue that need to be addressed immediately.

Using normal cruise control in the highway, my car brakes randomly and suddenly. This phantom braking has happened over 10 times in the past two weeks! It's very dangerous.

My Tesla model Y has been braking for no apparent reason when using the adaptive cruise control. Sometimes there may be a car coming in the opposite direction, but most times there is no other cars within miles. Several times the braking has been extremely aggressive causing me to have to hit the accelerator hard to avoid somebody behind me running into me. This has happened many times on long,straight, flat roads in the middle of the Arizona desert.

The contact owns a 2021 Tesla Model Y. The contact stated that the vehicle was taken to the local dealer for a wheel alignment, and at that time he was informed that the lower control link subframe needed to be replaced. The vehicle was repaired. The contact then stated that while his wife was making a right turn, the front passenger’s side control arm and wheel detached from the vehicle. No warning lights were illuminated. The vehicle was towed to an independent mechanic. The independent mechanic diagnosed the vehicle and stated that the two control arm bolts needed to be replaced. The contact was informed that the vehicle needed to be taken to the dealer. The vehicle was then towed to the local dealer, who confirmed the independent mechanic’s diagnosis; however, the contact referenced NHTSA Campaign Number: 21V835000 (Suspension) as a possible solution to the failure; however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was 32,386.

The vehicle brakes for no apparent reason without any other vehicles in near vicinity, both in adaptive cruse control and autopilot. This has improved with updates, but on a recent trip we experience six phantom breaking events on interstate travel.

Vehicle is experiencing “phantom braking”. Has happened dozens of times. I have contacted Tesla a few times regarding this, and they downplay everything.

While car was on cruise control. The car went off cruise control without intervention or warning and slowed down quite abruptly. This occurred about 4 times in a 4 hour period while going interstate speeds.

Multiple incidences of phantom braking while using cruise control/autopilot (not full self driving) traveling to/from Sacramento, CA and Park City, Utah on August 13th and 19th. This has happened previously while traveling to/from Sacramento, CA and Napa, CA. Unexpected hard braking on the highway at speeds of 55-85 mph) for no apparent reason is a hazard to the driver/passenger as well as any nearby vehicles. It causes undue fright, motion sickness, whiplash, and potential accidents. I contacted Tesla and they evaluated the car remotely and said they found nothing wrong. Yes, the car is available anytime for an inspection. No, the car or components have not been inspected by anyone, except as noted above by Tesla's service department. There were no warning lights/messages. This has been a problem for at least 6 months. It just became more evideent on our trip to/from Utah.

B pillar cameras have a known water intrusion issue rendering the camera inoperable and compromising the safety features of the vehicle. Tesla refuses to remedy this known design flaw.

Tesla's Traffic-Aware Cruise Control system has malfunctioned on my vehicle several times. It will often brake hard at high speeds despite there being no vehicle or object in front of me.
