What owners wrote
“First the car started jerking while drive over 50mph, next day driving down the street and the car shut off, stating loss of power. I replaced the battery, it was giving battery low codes, only to get a certified mechanic say the timing chain was out. Just purchased the car in March 2022.”

Should you keep driving it?
This page can't tell you that. 0 of 25 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
