Q. I’m in the market for a small SUV and heard about the new GMC Terrain. I know Honda, Toyota and even Hyundai make good products, but I wanted to buy a General Motors vehicle. What do you know about the Terrain?

A. When I first drove the Terrain, it was a four-cylinder version with front-wheel-drive. The engine was smooth, had plenty of power and delivered 27 miles per gallon in mixed driving. The ride was on the firm side, however, and the handling was average. On the other hand, when I drove the V-6 version, it felt like a different vehicle—the ride had improved, and the handling was also much sharper. Add in comfortable front and adjustable rear seats, rear view camera and a pleasant interior, and the Terrain is worth looking at.

Q. I have a 2003 Pontiac Grand Am and for some reason, my horn goes off randomly. It even happens when the alarm is not on. What should I do?

A. This is a fairly common problem with some General Motors vehicles. The way I understand it, the airbag cover shrinks. When this happens, there is just enough pressure to cause the horn to sound. The correct fix is to replace the airbag assembly, but considering the cost, I would be tempted to put a switch on the horn so you can shut it off at night.

Q. I just purchased a 1993 Chrysler LeBaron. With only 10,000 miles, it runs great overall. However, it makes a strange snapping noise when the car goes into gear. One shop determined that the exhaust pipe was shifting, but that didn’t seem to solve the problem. Any ideas?

A. Chrysler updated the engine mounts for a similar reason. This engine mount is a new “two-piece” slider type. When the long support bolt is tightened to specifications, the split slider tube locks and will not slide or move within the mount’s aluminum core. This new design should eliminate the snapping and clicking noise.

Q. I have a Honda Civic and the power windows are starting to move slowly. Does this mean my car’s window motors are wearing out?

A. The most common issue is the channel that the window slides in. You can try cleaning it with hot, soapy water. Once the window track is clean, lubricate it with silicone, but don’t use any petroleum-based lubricants—they will only attract dirt and cause more binding.
