Summary: The front suspension defect on my 2021 Model X, confirmed by St. Petersburg Service Center (Invoice #3000S0013156326), presents a serious safety hazard. Timeline & Concern: Reported Dec 4, 2024, under ESA. Example of Tesla’s delay tactics—service was scheduled only after warranty lapsed. Issue diagnosed in May 2025 as a faulty front upper control arm. Safety risk: Failure could lead to loss of control. I request a safety investigation to prevent similar unsafe compromises.
It is commonly known that the drive shafts on the Model X fail. This is not a wear component and should be a recall. The suspension is also part of this issue and there are after market solutions to fix the suspension that is causing the failure of the half shafts.
On May 23, 2023the car went into the shop for an unrelated issue at that time the tires were checked and found to be needing replacement on front, nothing in notes about back tires. Tires we're filled with air at tesla service. Through out the day on message through app with service no one mentioned tl me the customer that tires needed changing and I was let to drive out on newly pumped up worn tires. 2 days while on the road with my children the tire blew put luckily no one was injured and car had to be towed. At this point they said ohh the back tires are also poor we need to replace both and both were replaced. Several weeks after this a rattle developed and the car went back in in July and the control arm had to be replaced. In november the car started making...
At 50K miles the control arms on model X seem to always fail. This is a serious safety issue. My last model X had the same issue. Also my friends who have Teslas have many control arm failures.
On 10-16-21 Saturday around 7:40 PM, I was going to my brother-in-law's house which is on the left side of the road I was driving. It is a single lane road in a busy residential area. I wanted to park outside of the house by the road. I took a left turn towards the gate, then slight reverse and put in drive to pull to park parallel to the road. My Tesla Model-x went into 'Sudden Unintended Acceleration' mode, went left to right to left in a violent way, picking up speed like a rocket. I applied the breaks repeatedly, but the car did not stop and continued to race on the road for about 0.3 mile where the road takes slight left turn. It went and crashed into a 40 ft tall big pine tree at probably more than 150 mph. It knocked off part of the compound wall...
HERE IS A 2021 MODEL X IN THE JUNKYARD. HTTPS://WWW.IAAI.COM/VEHICLEDETAILS/39434989?TENANT=US&ROWNUMBER=19 THE BACK WHEEL AND SUSPENSION HAS SNAPPED OFF. THIS IS NOT THE RESULT OF A CRASH IT IS THE RESULT OF A MANUFACTURING DEFECT. THE LOWER CONTROL ARM HAS CRACKED IN HALF ALLOWING THE WHEEL TO GO WHOMPABOUT. JUST LOOK AT THE PHOTOGRAPHS. THESE LOWER LINKS HAVE SNAPPED MANY TIMES ALREADY AND HAVE CAUSED FATAL CRASHES. PLEASE PUT A STOP TO THIS TESLA MADNESS. THANK YOU. KEEF
