Check engine light was on and engine was running roughly. Faulty fuel injector was replaced.
SES light came on and scanned code P0008. Took it to dealer and they applied TSB.
Engine Timing Chain replaced under warranty
Diagnosed carbon build-up and misfires. Did not have $250 service.
Timing chain replacement
Stretched timing chains Check engine light related to stretched timing chains
Leaking valve cover, spark plug miss firing.
Emissions related sensor
Water pump replaced due leak after.
Low potency on low revolutions. Ignition coil #4 damaged. Also replace spark plugs.
Ignition coils #3 and #5 damaged
Joint seal damaged on exhaust system. Loss of engine power because that.
Engine and transmission mount points wear out
Discovered large pool of red fluid under my car. Took it to local dealer and was told it was the water pump, which was under a recall.
Check engine light came on. Took vehicle to auto part store for free diagnosis and was told 1 of the 4 oxygen sensors was bad. Purchased new sensor and replaced the part myself.
There are four O2 sensors in the Traverse. I have no replaced two. 2 down, 2 to go.
Check engine lit up because of a faulty purge solenoid on the gas tank
Check Engine light code was emission system vent solenoid.
Cam actuator fouled due to "dirty oil" after 8k miles. Oil life meter indicated another 15% oil life. Actuator replaced under warranty.
Replaced engine valve actuator for 2nd time due to sludging. Oil-life indicator not reliable. Mechanic recommended switching to synthetic oil to reduce sludging.
engine light on dashboard
I noted hesitation to dealer, computer revealed multiple events, so they recommended fuel injector cleaning. Seemed to fixed the problem.
Water pump started leaking thru weep hole. Puddle underneath. Dealer replaced water pump under warranty.
timing chain cover gasket
water pump failed. Replaced under warranty.
The oil change life sensor had to be reprogrammed.
Timing chain stretched. Engine was removed from car, timing chains were replaced, engine was put back into car.
The vehicle was due for an oil change (computer said 5% and the "change oil" message was displayed). After changing the oil, the check engine light has not come back on. Possible that fresh oil fixed the problem.
Check engine codes indicated problem codes from the crankshaft position sensor and camshaft position sensor. Diagnosis is worn timing chain.
Replaced timing chain under manufacturer's 100,000 mile powertrain warranty.
Water pump leaking, replaced.
Leak in radiator tank. Radiator replaced. (Attached to A/C condensor, so removal and replacement of freon is part of the job). 3.5 hours labor.
irregular shift pattern in transmission...still not fixed...have to take back for further investigation into problem
mass airflow sensor
same as usual...shifting just isn't smooth...the dealer thinks its computer problem..i think it's torque converter problem. i will try their latest fix and see what happens
Poor shifting still a problem. Had dealer put computer back tom original setting. New setting was causing poor fuel economy. Will have to move to next level with GM to resolve this problem.
Replaced leaking water pump. Had to take back to dealer twice. First install had bad gasket I was told.
Water pump leaking. had to return to dealer twice, first time repairs attempted still leaked.
Trans shifting problem, sloppy shifting. Followed TSB and reprogrammed transmission, now working great.
One week later, got an error code on the emissions system. Had the solenoid valve replaced.
Got an oil pressure low, stop engine immediately. Oil was added but mechanic said it was the communication system acting up.
timing belt/chain needed to be replaced
Leaking Gas Cap. Gas Cap Replaced
Plate cover on torque bar that connects engine place wrong causing clank sound when accelerating.
Check engine light. Sensor on transmission replaced under warranty.
'Service All Wheel Drive' message briefly appeared on DIC as well as message 'All Wheel Drive Off'. No other warning lights on. Dealer unable to replicate. Have since seen 'Service All Wheel Drive' message again.
Started running rough. Engine light blinked, indicating serious problem. Design issue with spark plug tubes causing oil leak in head. Head re-machined for new tubes.
Reprogrammed computer for check engine code.
Timing chain and associated components replaced. Water pump replaced as well.
Cracked Head bad o2 sensor
Oil leak from intake manifold. When the head was replaced the dealer didn't install the gasket that seals the intake manifold correctly.
Traverse would not start. Determined the issue was a FUEL PUMP CONTROL MODULE. It took two towed trips to the dealer to find out the problem. Called GM Customer Service. They offered Good Will Warranty. Accepted and appreciated.
AWD system MASS AIR FLOW DEVICE needed to be replaced. The DIC system in Traverse alerted to the problem, message that Stabilitrak disabled.
Stabilitrak error message back after 3 weeks. The wiring from the Mass Air Flow device was too short. Dealer lengthened the wiring to prevent shorts. Problem solved. Very Happy.
Original Water pump failed at 133K Miles. Check engine light on. Detemined that the Valve covers have to be replaced. Oil leaking into Fuel injection syetem causing Emissons.
CEL. First two trips to dealers replace oil cap and clean fuel system. Then say valve cover gaskets failed, possibly caused by clogged PCV. Allowed air to be sucked into engine, upset emissions. After repair by indy gas mileage has gone up. Check engine lite has come on and will not go off after repeated efforts. Now they have discovered that one side of the Engine burns leaner than the other. Shop took car to dealer, which found a partially clogged screen in one of the fuel rails.
