Known issues on the 2024 LYRIQ. Six recalls are on federal record for this model year. An improperly welded seat belt bracket may not restrain an occupant as intended, increasing the risk of injury during a crash. Insufficiently insulated wiring in the rear drive unit's electric motors can allow the wires to contact each other and cause a loss of drive power. The anti-lock brake system may activate unexpectedly and release brake pressure, causing a loss of braking ability. Improperly tightened front stabilizer bar bracket bolts can loosen and separate, with a detached bracket risking damage to the high-voltage cables or EV battery coolant lines. The driver video display may go blank while driving, cutting off the speedometer, warning lights, and rearview camera image. And the rearview camera screen may turn gray with no image, reducing rear visibility. Owners have filed 112 complaints for the year, and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From a rear drive unit inspection to a stabilizer bar bracket check or a high-voltage service procedure, it keeps you on the OEM sequence and the correct specification for your specific 2024 LYRIQ.
