| Suspension problems |
Car purchased in Feb 2022. November 9, 2023 after a couple of previous complaints about the car riding rough, this time , after telling them the car jumps and throws into the next lane, it was diagnosed as having passenger rear leaking strut, front pinion seal leak, front driveshaft c/v joint torn and leaking grease. These were repaired under warranty. Dec 2024: had noise and had vibration felt through floorboard - diagnosed with problem in front differential and found carrier bearing failure and damage to case from bearing failure/spun. The axle housing assembly was replaced. April 2025: transmission shifting hard and clunk noise as well as riding rough again. These transmission assembly will be repaired for known problems on original 10 speeds but they don’t fix until customer complains, the rear differential pinion seal is leaking and the front struts are leaking. Something is very wrong with the suspension, drive train and transmission in this vehicle.
