What owners wrote

“The water pump has been replaced twice already and the water pump needs to be replaced again at 105,000 miles. This will be the fourth water pump this vehicle has. The originally came with, two replacements, and now the one that it needs because it is leaking like the previous three. The turbo charger failed and was burning oil. That was replaced. A month later it is back at the dealership being replaced again”

Should you keep driving it?

This page can't tell you that. 1 of 26 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.
