My wife was driving the car down the highway and she said the car just died and rolled to a stop. I arrived on the seen and popped the hood. I didn't see anything unusual but she mentioned to me the engine wouldn't turn over at first then after a couple trys it did. i thought dead battery, alternator went out and car died. hooked up cables to jump no luck. car just cranked over but didn't seem right. I called tow truck 70 bucks and it was at auto repair place. showed up there after work and was told timing chain broke and it is an insync engine so not only will my engine have to be pulled to put a new chain and gears on but the valves will be bent from hitting the pistons and head will have to be pulled and the valves replaced and gone through. so this will cost 2400.00 or so. i could get a used engine for 2500. wow for a timing chain are you kidding me. Pontiac is junk. i bought the car brand new with 4 miles on it and took good care of it with oil changes and have had more problems with it than any vehicle. So after the auto place pulled valve cover and charged me 70 bucks i got to pay the tow company to bring it to my house another 65 bucks. my thought is to pull engine myself and send head to guy to go through and put a new timing chain and gears in it.

My wife was driving the car at 60 mph. Car suddenly lost power and she was able to get car to side of road. This happened on rt9 in Middletown CT during morning rush hour ( speed limit on road 65mph). Car wouldn't start. Had car towed to garage and problem was found to be broken TIMING CHAIN. Yes, the chain not a belt. Mech couldn't believe that a timing chain broke at 95000+ miles. Engine cannot keep compression in cylinder 1 + 3. Looked online and found that this is a common problem for the 2002 Pontiac GrandAm with the 2.2l Ecotec engine. One guy had the chain break at 57000+ miles. Had car towed to GM garage and after 150 for diag fee, they said that the timing chain went to pieces and the engine is no good. Need new engine. Contacted GM and they refuse to do anything about it. First it was that the warranty is over. Then it was that if it had under 80000 miles they would have done it. Kept complaining and then they said that if it had under 90000 miles, they would have done something. Obviously, they know about this problem and just refusing to do anything about it. Seriously thinking about contacting Atty General, BBB and also filing small claims suit against GM for this obvious engine defect. Also, we always had regular maintenance done to it according to schedule. Anyone else with this Engine, should probably see a mechanic right away to see it adjusting tensioner might help. New engine will cost approx 3000 - 3500 to buy and have installed.
