Well my wife was driving the car on freeway with our kids and check engine light came on and then the vehicle powered down, we felt like it was timing chain and turns out it was. . General motors fixed timing chain problem but now the dealership says all three catalytic converters are bad because of gas seeping in because of the timing issue and to fix the converters it will cost upwards of 2500 dollars. . . So if someone could please advise of any known recalls please. . . Also we just bought the truck two weeks ago and with seven kids don't have the cash laying around for such a expensive repair that we feel should be covered if caused by the timing issue in the first place.
My wife was driving home when the check engine light came on vehicle lost power and stalled and would not restart, vehical was towed to dealer who stated cathlitic converter had failed and would be replaced. Following replacement dealer stated engine backfired during test drive investigation revealed engine failure and had to be replaced luckly insurance covered this repair, following engine repair car was started but still backfired investigation revealed ignition coil was defective. . Reshearch by me on the internet showed problems with ignition coil causing engine and cathlitic converter problem, this problem could be a major safety concern if driving at interstate speeds then this problem occures.
2009 Traverse purchased 4/30/2009. From the start it had a check engine light on but no symptoms of failure. We took it to dealer 1 on 9/02/2010, with 22,753 miles. They replaced wiring under engine plenum to #1 ignition coils. A couple of days later, the check engine light came back on. At this time the car started to lose power on the freeway sometimes. We took it to dealer 2 on 10/11/2010, they had to get parts and did a temporary fix. We brought it back on 11/1/2010, with 24,656 miles on it and they supposedly fixed it. They replaced connectors in the junction box, saying it was an electrical problem. The light was back on within a few days, and the car was still losing power. We took it to dealer 3 on 2/09/2011, with 30,287 miles for check engine light, and loss of power. They replaced ecm and all 6 coils. The day we left the shop, the light was back on and within a day the car was losing power again. Back to the shop on 2/17/11. This time they replaced the catalytic converter. The day after we left the shop the light was back on. They told us it needed a small adjustment and to bring it back on 3/05/11. We went to the shop and the mechanic did not know how to fix it. After being there for a few hours and calling chevy 800 #, they told us to come back next week. On 3/06/11, the car was losing power so bad that we wanted to take it back to the shop, but they were closed. On 3/07/11 the Traverse started losing power, and then died. It lost all power and the brakes failed as a result. We had to slam on the emergency brake to not have an accident, and were lucky to not be rear ended. The car has been at the shop the week of 3/07/11-3/11/11. They told us the car is misfiring on all cylinders and dumping raw gas into the exhaust. On 3/11/11 they called to state that they are replacing the catalytic converter (again) and the module and returning the vehicle on 3/14/11.
