2018 Tesla Model 3 Suspension Problems

Following a professional suspension repair at a Tesla Service Center, critical underbody fasteners (bolts) became loose, causing the aero shield to sag and creating a potential road hazard. Upon inspection, the service technician confirmed the bolts were unsecured. The failure of these fasteners on a safety-critical system poses a risk of parts detaching while in motion or loss of vehicle control. The service center refused to acknowledge this as a workmanship failure under the 12-month repair warranty, despite the fasteners being last serviced by their technicians.

2018 Tesla model 3 front chassis subframe welded nut to the chassis is come off now left side control arm keep getting loose

I purchased this car new in 2018 and recently replaced the front lateral suspension arm due to worn bushings. During the process, I discovered that one of the 14 mm bolt threads on the right side of the suspension arm had a helicoil inserted. While removal was straightforward, reinstalling the bolt proved difficult. I spent several hours reattaching it to the new suspension arm, but did not apply full torque, as I was concerned about damaging the helicoil or stripping the thread. My main concern is that the factory has stripped the original thread and used a helicoil instead of replacing the affected part. Although the repair has held so far, I am unsure if this is a safe long-term solution, as the helicoil could fail while driving. I contacted Tesla, who advised me to visit their service center. At the Centinela location in Los Angeles, the supervisor informed me that, since the warranty has expired, they can only perform a visual inspection.

Front suspension creaking noise, took in for service, techs ultimately found the front subframe captive welded nuts that secure the front links had sheared off, requiring a replacement of the subframe and some other suspension components. Nuts, which were initially welded to the subframe during assembly, were loose on both sides. No associated damage or impact, normal use over 7 years of ownership. This is also a common issue, and is already associated with a very limited recall (21V-835) but for whatever reason, this failure is still occurring quite often in the wild - normally with far more extreme consequences than in my case.

The front passenger side upper control arm is squeaking and causing vehicle to drift to right, vehicle only has like 60k miles and the upper control arms have been replaced by Tesla before

The contact owns a 2018 Tesla Model 3. The contact stated that while his wife was driving at slow speeds, after completing a right turn, there was an abnormal sound coming from the front passenger’s side suspension. The contact stated that increased effort was required to maneuver the vehicle. No warning lights were illuminated. The vehicle was towed to the dealer, who determined that the passenger’s side control arm had disconnected. The contact was informed that two bolts that secured the control arm to the frame were missing. The contact also stated that the bolts were found by the tow truck driver while loading the vehicle for towing. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 95,000.

My car started having loud noises and suspension on both side of my car started making noises and both control arms along with sway barrings and struts are gone bad.

Front suspension creaking & rattling going over bumps Tesla took days & days & never called me w/ problem I kept calling in!! Finally decide it is a KNOWN recall problem w/ Suspension bolts & sub frame! They told me they torqued them & would test drive for noise & I never heard from them! I had to call in. Suddenly I had a $4200 estimate for repairs including $322 1.24 hours of diagnosis??? A known problem other 2018 Tesla’s have been recalled for ??? Very suspicious?? How do I know they didn’t torque it too far & strip bolt themselves??

The first time the lower Lateral Links on the front right side just broke and luckily it didn't happen on the highway with passengers Right now I hear the same noises again coming from the driver's left side from the lower Lateral Links I am afraid that it will happen again and that’s really scary I drove many cars before and never felt so unsecured I don't understand how such a safety problem is not being addressed. I hear and read that other Tesla owners are also reporting the same problem.

Front suspension is making very weird and loud noises. Issue is associated with the front suspension links becoming loose.

The front suspension lateral link on our Model 3 came detached from the subframe as the bolts someone loosened. This is a known issue and Tesla has issued a recall (NHTSA Recall No: 23V-235) on this year Model 3, but our VIN is not included in the recall. It seems that this issue is wider than the cars the original recall has included. Upon detachment, the wheel steering did not work, and if it highway speeds, could have cause a fatal accident.

The car started making a strange high pitched creak sound whenever I would turn the steering wheel, or go over bumps in the road. I brought the car to Tesla and they informed me that the following parts needed to be replaced. 1. Front Lower Compliance links (left and right) 2. Front Lower Lateral Link (left and right) I was notified that the failure of those components was a potentially serious safety issue, and that the parts needed to be replaced as soon as possible. I had Tesla replace the parts, so the issue cannot be inspected. The problem was verified by the Tesla Service Center, and was not seen by any other professionals. There were no real warnings, other than the annoying squeak sound whenever the sterring wheel was turned. The sound first appeared in November of 2024.

Control arm issue and linkage cable.

Control arm of the left front suspension system detached with no warning other than an occasional noise that started about 2 weeks before the incident, usually when turning the front wheels at slow speed. This was a potentially dangerous situation for the driver, passengers, and any other vehicles on the road as the tire could have come off at any time. Fortunately the car was being parked (0-1 mph) in a non-congested area when the control arm detached. The vehicle (total mileage approximately 42k) was towed to a Tesla Service Center 2 days later where the problem--first diagnosed by the tow truck driver--was confirmed by a Tesla service representative. There was no warning of any problem other than the occasional noise mentioned previously. If this parts failure had occurred at high speed on an interstate highway, it would likely have been deadly!

The suspension on this car developed a persistent noise that worsened over time, prompting me to schedule a service appointment at the Tesla dealership. Although my car has less than 40,000 miles and has been driven primarily on well-paved city roads, both front suspensions were found to require extensive repairs, a final bill of approximately $2,100. Safety Concerns: Frequent Suspension Issues in Teslas: Online research and data from the NHTSA indicate a disproportionately high number of suspension and steering complaints for Tesla vehicles. In 2023, Tesla owners filed over 260 complaints, significantly higher proportionally than Toyota, despite Tesla's much smaller sales volume. Such trends suggest potential systemic quality issues in Tesla’s manufacturing process. Simultaneous Suspension Failure: The need to replace multiple components in both front suspensions at just 30,000+ miles raises serious questions about the reliability and safety. A single suspension failure could be a bad luck, but simultaneous failures point to broader design or manufacturing problems. Risk of Accidents: Suspension failure compromises vehicle control, increasing the risk of accidents that endanger drivers, passengers, and others on the road. Transparency Issues in the Repair Process: The initial repair estimate of $200 excluded labor costs and was revised to $400 without prior clarity. After inspection, the cost escalated to $2,100, leaving me no option but to approve the repairs without the ability to verify their necessity. Lack of transparency in repair recommendations, coupled with Tesla’s track record of suspension complaints, undermines customer trust and raises concerns about the integrity of the repair process. In conclusion, my experience highlights potential safety risks and quality control issues with Tesla vehicles. Suspension defects not only burden customers with significant costs but also pose a serious hazard on the road.

Front suspension lateral link fasteners loosened, allowing the lateral link to separate from the sub-frame. I have a 2018 Model 3 and this seems to be the exact same issue that led to a recent recall with the help of the NHTSA. Recall no. 23V235000 SB-23-31-001 An expansion of previous recall number 21V-835. I noticed for months something was slightly off in the front right area of the car. I brought it into the Tesla service center, they drove it and didn't notice anything. About a month later the lateral link separated from the subframe rendering the car undriveable. I had it towed immediately.

Vehicle Information: Make: Tesla Model: Model 3 Mid Range Year: 2018 VIN: [XXX] Mileage: 60,000 Issue Description: My 2018 Tesla Model 3 is experiencing premature wear of the front upper control arm ball joints and lower links at only 60,000 miles, despite the sealant fix from Tesla Service Bulletin SB-20-31-006 being previously applied. This premature wear suggests a defect in materials or design and poses a potential safety risk due to compromised handling. Request: I would like some information on the current situation, if tesla has already told their stance on the issue, if I qualify for any coverage even out of warranty. Anything that can help others when their suspension front goes out extremely prematurely.

Under-torqued Lateral link bolt These bolts are known to fall out or cause damage to bushings from being installed improperly Failure of the suspension would result in the suspension collapsing and the car becoming uncontrollable, with serious risks at higher speeds Out of pocket repair has been made by Tesla Component has been inspected and tightened to spec No warning sings, other than loud, clunking noises At 40k miles on smooth roads, this is not a driver issue, but a manufacturer assembly issue. They already have a recall for other VINs in other years, but I believe this should be expanded to more VINs and years, as this appears to be a common issue.

The contact owns a 2018 Tesla Model 3. The contact stated that while making a right turn, there was a loud bang, and the vehicle came to a stop. The contact stated that the bolt left lateral link on the suspension was hanging with the bolt detached and the second bolt missing. The vehicle was towed to a dealer where it was diagnosed that the left lateral link suspension subframe, steering rack, and driver’s side fender needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V235000 (Suspension). The manufacturer was notified of the failure. The failure mileage was 81,976.

I was called told suspension issue unrelated to accident. Sounds like a recall from the same year and same model. Could it be under this recall?
