2018 Subaru Forester: ball joint or control arm failure

Filed Nov 9, 2025 · Suspension · NC

I was driving on the interstate when car started vibrating and making a terrible sound. Dealership advised both front lower control arm bushings were worn and had play. Had them replaced but because they are rubber technician advised this will most likely happen again. My car has only 46k. I bought it new in 2017.

- Steering and suspension were affected. The car is available for inspection upon request. - My safety and the safety of others were affected by the fact that the car was shaking rather intensely while driving at highway speeds. I was worried a steering failure could occur. - My licensed mechanic diagnosed the problem as a right front lower control arm assembly problem with torn bushing. (Please see attached.) He replaced the assembly. Shortly thereafter, the steering wheel would feel occasionally loose and move on its own. The mechanic then did an alignment which did not help. The steering issue that came about after the control arm assembly was replaced is the subject of a complaint I filed with you yesterday: 11683647 - The problem being reported here has not been inspected by the manufacturer, police, insurance representative or others. - There were no warning lamps, messages or other symptoms of the problem prior to the failure. - Interestingly, the failure of the control arm assembly occurred at 51012 miles, right after the warranty ran out. My wife and I are seniors and we drive with care. Under the circumstances, this component of the car should have lasted much longer than it did. Now we worry the left side assembly may fail, especially since we have a loose steering problem that I reported yesterday.

1. The car's steering could be malfunctioning . The car is available for inspection upon request. 2. The steering wheel occasionally and without warning suddenly FEELS loose and "disconnected" from its ability to steer the car -- until I turn the steering wheel about a quarter to a half an inch and the steering FEELS normal again. I worry the issue (which so far has not interfered with steering the car) may worsen and possibly become hazardous. 3. I took the car to my regular licensed mechanic who did not experience the issue when he drove it. Nevertheless, the issue reported here exists as my wife and I have each experienced it. 4. The steering has not been inspected by Subaru, the police, insurance reps or others, other than my regular mechanic who has found no issues with the steering. 5. There were no warning lamps or messages prior to the issue first occurring except for the replacement of a tie rod by my regular mechanic, which may be coincidental. 6. This issue has existed since at least last February with no worsening of the condition. My regular mechanic has assured me there is no danger as he has checked the mechanical aspects of the steering (linkages, tie rods, etc.).

The lower right control arm bushings failed on the vehicle and the transmission is leaking. The vehicle has been owned by only two individuals, and was purchased by me in 2021 as a certified pre-owned vehicle from a local dealer. In three years we have put about 12,000 miles total on the vehicle (average of 4000 miles each year for three years), and the vehicle is solely driven locally on surface streets. This appears to be a known issue as noted by Subaru owners expressing frustration in public forum about premature failure of the control arm bushings.

Control arms failed within 55,000 miles, shaking and dangerous conditions for a vehicle less than 5 years of age. Leaking air condition and numerous electrical issues started ironically just after the standard 35,000 bumper to bumper warranty extended. Now my car smells like coolant and worried it’s going to overheat. All my tire sensor pressure gages burn out before 50,00 0 miles and needed replacing. Violent shaking of suspension at highway speeds and not one safety alarm goes off.

Needed to replace a wheel bearing and a front control arm bearing at 18k miles. Have seen multiple reports of the control arm bearings going bad prematurely on these vehicles and it seems this could be a serious safety concern. There should probably be a recall for the front control arms on this year/make/model.
