2021 TESLA MODEL Y Complaints

Occasionally, while the Adaptive Cruise Control (TACC) is engaged, the vehicle will suddenly brake as if there is an obstacle immediately in front of the car, even though there is not one and the road is completely clear. Sometimes this happens randomly on a divided highway, other times it happens on a two-lane highway when a large truck is approaching in the oncoming lane. Sometimes it is a minor deceleration, other times it is aggressive braking. During one particular road trip, on an empty & divided highway, the vehicle braked unnecessarily over 20 times in a 1 hour span. This is an ongoing issue and continues to occur any time TACC is engaged and there is a clear, unobstructed road ahead of the vehicle. This prevents a safety hazard to any vehicle(s) following behind, as well as the occupants of the offending vehicle, because it could directly result in being rear-ended. When I initially reported this problem to Tesla in December of 2021, they refused to acknowledge it, much less attempt to address it. I submitted a second request for service that same month, 3 weeks later, and their response was the same. However, when I submitted a third request this month (April 2022), the dealer finally confirmed that this is indeed an issue. Yes, the vehicle has been inspected by the manufacturer. No warning of any kind accompanies the malfunction, and there are no discernable symptoms.

I was driving on full self driving assistance on the highway on the far left lane. I wanted to change lane to exit but notice a car was in my blind spot so I tried to take over the car my tugging the wheel. The car sounded an alarm indicating I was going to crash I think into the left median, so it auto corrected to pull towards the right lane. I didn't want to hit any incoming car so I tried to tug it left. I believe I was fighting with the car to regain control of the car and ended up hitting the left median which ricochet the car all the way to the right hitting the median, where the car came to a stop.

When my Tesla Y is in cruise control, there have been intermittent unexpected slow downs causing the car to abruptly slow down on the highway. On my last road trip it happened about 5 times.

While driving in the adaptive cruise control the vehicle will suddenly go into a hard brake while at highway speeds. This has happened multiple times during both day and night, on roads varying from two lane highways to larger multi lane interstate freeways, and during weather conditions have always been clear. This feature has been typically only been used when traffic is light, as this problem has been documented by countless Tesla Y owners. This issue has been documented and reported to Tesla via the in vehicle reporting feature. When this happens it is a sudden and unexpected action that may cause another vehicle to rear end me, and or possibly loose control during the hard and sudden braking.

Tesla’s automatic wipers does not always work and it’s a serious safety concerns. I have videos of the automatic wipers not working during a light and heavy rain and it hindered visibilities on the road. Sometimes I traveled for 2 mins without the wiper sweeping water from the windshield. Due to Tesla’s bully tactics, and retributions, please do not share my name or phone number with Tesla, thank you.

My wife weighs 108lb the manual says the passenger airbag should be on if a person weighs approximately 100lb. About 80% of the time she sits in the passenger seat the seat does not detect she is there and it says the airbag is off. I took this to Tesla to repair and they said the sensor was working as designs. I feel this is a safety issue.

While driving on interstate 25 the adaptive cruise control braked hard for no reason. There wasn’t any hazard and no traffic on clear days on a well marked road. It happened quite often . More than 100 occasions on a 65o mile drive.

When driving the vehicle primarily on highways and with the Adaptive Cruise Control active, the car randomly reduces the cruise speed by up to 35 mph and then proceeds to slam the brakes. This happens intermittently on open road, 4 lane highways, with and without any traffic nearby. We logged the times that these occurred and took them to our local Tesla service center and they said “This is a software bug that we have to wait for Tesla to fix. There is no way to disable the adaptive nature of the cruise control either.” We informed them that this has been occurring for about 6 months now and they said “You’ll just have to wait until Tesla fixes the code. It gets better every release so eventually it won’t do this anymore”

All of these incidents occurred with adaptive cruise control engaged, and sometimes with lane keeping engaged. The vehicle frequently brakes, or slows dramatically, when on the freeway and there is no obstacle in the vicinity. Over the last three days I made the drive from Burbank to Anaheim along I-5. Always in the same area, the car would suddenly slow. In two out of the three incidents, the "max speed," which was set to 80, dropped to 45. Simultaneously, the car thought it was in a 55 mph zone (it was a 65 mph zone). In one of the three instances, the max speed was not changed, but the car still slowed dramatically. On the same commute, the car navigation always has me get off on Artesia Blvd, and then get right back on the freeway. The adaptive cruise has a configurable follow distance that the car seems to generally ignore. It's a number from 2 to 6 or so, and it's not clear what it's supposed to be (seconds or car lengths). It's rarely either, although it should represent seconds. When traffic comes to a complete stop, the car waits until it is too close to brake. When traffic begins moving, the car waits too long to start moving, and then accelerates excessively to catch up. Finally, when using the regular adpative cruise and lane keeping, I would signal lane changes and initiate the change. The car disengages steering but maintains cruise. In many cases, while still indicating the lane change, the car's lane departure warning will sound and it will attempt to correct my steering, which I have to physically override. My Nissan Leaf had adaptive cruise control, lane centering, and lane departure avoidance, and it never gave me these issues. Oh also, the Tesla frequently and erroneously warns of forward collision. It's really terrible, and it's due in no small part to the removal of the forward radar sensor.

Over the course of an eight hour drive on a single lane highway, the vehicle abruptly applied brakes without any warning at full speed multiple (at least 30 times). In some instances, there were vehicles in the opposite lane. In other instances, there were none. In all cases, there were no vehicles in front in the same lane. Weather conditions were clear and dry, with full daylight illumination. This issue is most likely related to the camera-only change made to Tesla vehicles, which are used for TACC and autopilot features.
