NHTSA complaint #11350116, filed 2020-08, 100,000 miles“Whenever I am driving my vehicle for an hour it starts to stall or sputter in traffic and the engine dies completely. It will restart but still continues to hesitate when accelerating. I've taken it to a mechanic and no error codes pop up when this happens so they do not know the cause or how to fix the issue.”
NHTSA complaint #11252020, filed 2019-08, 123,964 miles“The driver side light bulb & connector melted. Bulb can not be replaced because housing is damaged. Contacted the dealer and I was told this is not covered by any recalls. I would be responsible for any parts. This is definitely a factory defect and car is not safe to drive. The only way to fix this per the dealer is to replace complete headlamp assembly.”
NHTSA complaint #10787038, filed 2015-10, 95,000 miles“The passenger side light bulb melted. Bulb can not be replaced because housing is damaged. Contact the dealer and I was told this is not covered by any recalls. I would be responsible for any parts. This is definitely a factory defect and car is not safe to drive. I have ordered part and I'm still waiting for replacement from dealer.”
NHTSA complaint #10654059, filed 2014-11, 71,000 miles“Takata recall - there is an issue with the ballast in the hid headlamp assembly for the cxl turbo model. The seal may be faulty due to the headlamp shorting out except for the daytime running lights. They shorted out right after a heavy downpour and I was stopped by a police officer and told that they (the headlights) were out. I got out of the vehicle and looked at the the lights only to realize that they had malfunctioned and there was moisture in the assembly itself.”
