NORTH TEXAS (CBS 11 NEWS) – If you don’t have one of the vehicles affected in the latest General Motors recall chances are you probably know someone who does. Earlier this week, the automaker announced the recall of more than 3 million vehicles. The latest recall is on top of the more than two million vehicles previously recalled for the same reason – an ignition switch problem.

At Auto Maxx used car lots in North Texas, there are clusters of specially marked vehicles with, “GM recall. Do not sell,” written on the window. Those cars are heading to a dealer for repair, but not all used car sellers may be as thorough.

“You know, with a lot of the attention with the safety recalls that we’ve heard recently it is alarming for folks who want a safe and reliable vehicle,” said Doug Shupe of AAA Texas.

GM is recalling cars for ignition problems dating back to 2000, which means used car buyers should beware.

Carfax estimates 3.5 million cars for sale online last year were recalled and not repaired. If ever was the case, consumers need to be wary when buying used vehicles.

“Really, be proactive about this,” Shupe warned. “And doing the research before you purchase the used car is really crucial to the consumer.”

“Make sure you keep a copy of all those work repair invoices for your own records,” Shupe advised. “Make sure the vehicle manufacturer knows your current address and that its updated. Don’t rely on the used car dealership or the private owner to let the manufacturer know that you are the new owner of the vehicle.”

Vehicle owners can also call the GM information line at 800-222-1020 to find out more.
