Open the full vehicle complaint log (all categories)I purchased this vehicle new in September 2025. At approximately 3,903 miles, the vehicle exhibited a failure of the transmission system affecting its ability to remain stationary when placed in park. When the vehicle was placed in “Park” on an incline, the park mechanism failed to hold the vehicle, and the vehicle rolled despite being in park. This condition presents a clear risk of unintended vehicle movement. The issue was verified by the dealership during a test drive. Diagnostic inspection confirmed that the gear selector and transmission position indicators were functioning correctly; however, the vehicle continued to roll freely in park. The parking pawl was audibly engaging but failed to mechanically secure the vehicle. No diagnostic trouble codes were present, and no evidence of external damage, improper use, or installation issues was identified. The failure appears to be internal to the transmission system. This defect occurred at very low mileage and involves a core safety function intended to prevent unintended vehicle movement. Based on these facts, this issue is being reported as a potential safety-related defect. The dealer had the vehicle for over 30 days and installed a completely new transmission.
Issue: Engine stall & loud tapping/grinding noise Vehicle only has 1,100 miles and has stalled about 5 times when slowing down to about 10mph & then accelerating again. Issue has also happened when going about 3mph & then accelerating. About 10sec stall & then vehicle takes off. Several of the stalls happened even though the Auto/Start switch was engaged to disable feature since I thought maybe a bad switch was the issue causing the stalls, but stalling happens with it on & off. Another issue engine makes a tapping noise when in gear & accelerating up to about 1200rpm. Issue has been getting louder since purchase. At 1100 miles started car & pulled into garage after vehicle set for about 2hours (75F outside), upon doing this the engine sounded terrible like there were a handful of marbles in the engine, super loud sound, at this point made appointment with dealer, but they are so backed up vehicle can't go in for service for about 2 weeks per no loaner car available until then, since it can take up to 1 week to get looked at. Will update with their findings but looking at form pages & You-tube videos it seems like the ongoing engine tapping complaint resulting in an engine replacement & maybe part of the 2024 recall Valve Spring breaking resulting in the loud marble sound I am hearing. Car stalling is a major safety concern since a few of the stalls happened when pulling in front of traffic going 60mph.
