A front suspension link on about 1.2 million older Teslas can detach with no dashboard warning, and a car that loses it may not be drivable afterward. On July 29, 2026, the National Highway Traffic Safety Administration opened a preliminary evaluation, numbered PE26006, into that failure. It covers 2018-2020 Model 3 sedans and 2021-2023 Model Y crossovers, and as of Nov. 12 it is still an open investigation rather than a recall.

A preliminary evaluation is the first rung of NHTSA’s defect process. Investigators have not declared a defect or ordered a repair, and the agency’s stated aim is to learn whether a pile of complaints shares a cause.
The front lower lateral link and the 1,198,300 vehicles in PE26006
NHTSA’s Office of Defects Investigation estimates that 1,198,300 vehicles are covered by the evaluation: Model 3 cars from model years 2018 through 2020 and Model Y vehicles from 2021 through 2023. The component is the front lower lateral link, a suspension arm that ties the wheel assembly to the car’s body. The opening resume, signed by investigator Stefanie Oldenburg, reviewer Sharon Yukevich and approver Tanya Topka, says detachment “potentially causes a loss of vehicle directional control.” The evaluation grew out of a review of vehicle owner questionnaires, the complaint forms drivers file with the agency.
The warning problem sits at the center of the case. In most of the reported failures, owners got no advance indication. A few heard noises beforehand, but the cars gave no visual alert, and once the link let go the vehicle might not be drivable and would need a tow.
The complaint count is specific: 156 complaints alleging suspension failure, all of them filed directly with the agency. The resume lists no Early Warning Reporting data from Tesla, no dealer or field reports, and no crashes, fires, injuries or deaths. Autobody News, which reported the probe on Aug. 11, repeated the 156-complaint count and the absence of any reported crash or injury.
Recalls 21V-835 and 23V-235, and why NHTSA says they fall short
Tesla has been here before with the same part family. Recall 21V-835 covered 2,791 Model 3 vehicles from model years 2019 through 2021 because of a production issue, and recall 23V-235 covered 422 Model 3 cars from model years 2018 and 2019 with similar failures. NHTSA’s notice for the 2023 recall warned that a separated link could alter wheel alignment and raise the risk of a collision.
The new resume says the current failures go beyond the scope of both campaigns and do not appear related to the production problem behind 21V-835. The two recalls together touched 3,213 cars. PE26006 reaches more than 370 times that number.
Electrek, in its July 31 report on the opening, added that a separate suspension inquiry into the Model S and Model X closed in 2024 without a recall, although NHTSA recommended a part change at the time. The outlet also said Tesla has historically pointed to isolated causes when suspension complaints surfaced.
Owner accounts and Tesla’s silence on PE26006
None of the coverage reviewed carries a Tesla statement on the investigation. The only owner narrative in the sources is a single reader comment under the Electrek story, so it is unverified: a 2023 Model Y owner described hearing knocking while turning soon after new tires were fitted, finding a loose nut traced to a front axle joint, and being told by Tesla that no recall existed even though the company towed the car and covered the repair under warranty. Treat it as an anecdote that matches the pattern NHTSA is testing, not as a finding.
What happens next follows NHTSA’s usual path. ODI says it will determine the underlying cause, scope and severity and assess the related safety issues. An evaluation can close, lead to a voluntary recall, or be upgraded to an engineering analysis. For scale, the agency’s separate probe of Tesla’s driver-assistance software was moved to an engineering analysis on March 18, covering about 3.2 million vehicles across Tesla’s lineup.
Battery wear in the same 2018-2020 Model 3 era
Suspension is not the only aging question for these cars, and the battery picture is considerably brighter. A Swedish used-EV retailer, Carla, analyzed 9,954 battery tests from 2022 through 2026 using AVILOO diagnostics, which measure the pack’s actual state of health rather than the dashboard estimate. Electrek’s July 15 write-up of that data found that Model 3 cars past roughly 62,000 miles averaged 93.3 percent health with the CATL lithium iron phosphate pack, 91.5 percent with the LG Chem nickel pack, 89.8 percent with the larger Panasonic pack and 88.2 percent with the smaller Panasonic pack.
Those numbers come from Swedish cars and say nothing about the suspension link, but they frame the used-Tesla market that PE26006 now touches. The open question is whether 156 complaints turn into a recall request, and the resume gives no date by which ODI must decide.
