The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

RepairPal Expert Overview:
The outboard release handle on a second row bucket seat may be activated during a side impact crash. This could cause the rear seat latches to disengage, increasing the risk of injury to the seat occupant. Dealers will remove the seat latch release handle and install a plastic cap to eliminate this side impact safety concern. This recall is expected to begin on April 5, 2005. The General Motors recall number is 05015.
RepairPal Expert Overview:
Certain sport utility vehicles fail to conform to the requirements of Federal Motor Safety Standard # 135 "Passenger Car Brake Systems" To meet the standard, vehicles must not move for 5 minutes when stopped on a steep hill with the parking brake applied and the vehicle in neutral. Some of these vehicles failed this test. When the parking brake is released the driver may notice unintended braking while accelerating, decelerating or coasting. This could lead to unintended vehicle movement and cause an accident. The dealer will inspect each rear parking brake caliper and replace free of charge if slippage is noticed. The GM recall # is 05059

2005 Pontiac Montana Reviews
I have a 2005 Montana. It has been a very reliable car. I have put quite a few brake pads on the car seems to go thru them and then they squeal. I replace about every 30000 miles. My main issue with it now is that from a cold overnight start I get bad gas fumes once car warms up there are no more fumes. Still trying to locate what is causing it. Took it to the shop and they say I have no leaks. They have had me put in fuel injector cleaner says they should help I am on second bottle and still has the smell.
I purchased the car in 2006 it was a 2005 with 360000 miles. It now has 850000 miles and has penny and dined me to death. First the fan belt, right door electric window stopped, then the wind shield wipers , then the electric mirrors, and today the cargo door came off the right side and the left side is making the same noise as the right side before it came off. I brought a used hyundai the same year a 2002 with 104000 miles and have had no problems.
Very solid van. Cool exterior (mock suv), great ride. Pros: huge power (its crazy how powerful the engine is, you can actually smoke your tires in this); great handling and ride; great interior comfort (air/heat in front, mid, & back); comfy seats; highly reliable van. Cons: poor placement for DVD controls (you cannot adjust movies for little ones without leaning way back or being in back); rear seats suck to fold up or to take out/put back in (they are heavy too rigid, and are not labeled for ease of reentry).
