NHTSA complaint #11327100, filed 2020-06, 10,000 miles“A vehicle diagnostic scan dated 04/15/2026 showed electrical communication faults involving vehicle control modules.

NHTSA complaint #11747863, filed 2026-07“The vehicle has a recurring interior rattle / loose-trim concern involving interior panels, trim, speaker/subwoofer area, rear shelf, dashboard area, or related mounting components. The noise is not merely a comfort concern if it is caused by a loose component, fastener, grille, panel, or speaker housing that may move, worsen, detach, or distract the driver. …”
NHTSA complaint #11747854, filed 2026-07“The sunroof has a recurring mechanical/electrical malfunction. During operation, the sunroof binds and makes a loud popping or cracking noise, and the rubber seal became torn or damaged. This suggests a possible track, guide, cable, motor, regulator, frame, seal, or alignment failure. This is being reported as a safety concern because a binding or popping sunroof can distract the driver, allow water intrusion into electrical areas, worsen into glass/track/frame failure, or create a risk of loose roof components while the vehicle is in use. …”
NHTSA complaint #11747811, filed 2026-07“Visible wiring has become exposed in the windshield/A-pillar area. There is no airbag/SRS warning light at this time, and I am not able to determine from visual inspection whether the exposed wiring is related to the restraint system. However, this is a safety-sensitive area because it can contain or route electrical wiring near trim, sensors, and safety-system areas. Exposed or unsecured wiring in this area may create a risk of electrical short, damaged wiring, impaired signal integrity, loose trim, moisture intrusion, or safety-system malfunction. …”
