2009 Chevrolet Malibu
Engine not specified
3.5V6 engine has a rough idle, took back to dealer 3 times and dealer stated this is normal for this engine. Dealer stated that Mfg's now set the fuel very lean and this causes the rough idle. I am taking vehicle to another GM dealer.
Unable to get read-out check engine due to a short that was blowing fuses. Seems to be related to our use of ethanol-added to the gasoline. Seemed to get better with a tank of ethanol-free gas. In Aug. traded it in for a 2016 Malibu 2LT.
check engine light on
fuel injector problems
Exhaust Cam Solenoid stuck caused check engine light to come on. Repaired under original 3/36 warranty.
Check engine light came on. Had to have cam phasers, both intake and exhaust, replaced again.
SES/Check engine light illuminated on dash. Scanned Code P0013. Diagnostic found exhaust cam position solenoid had debris trapped in it. Replaced cam position solenoid. SES/Check engine light illuminated intermittently. Scanned Code p0010. Diagnostics found intake camshaft position sensor sticking. Replaced camshaft position sensor.
Engine missing during idle. #1 fuel injector harness was replaced.
OBDS reported bad thermostat. Thermostat replaced and changed coolant as preventive maintenance.
check engine light came on
Camshaft solenoid failed and was replaced. Tripped the CEL.
"Service ESC" warning flashed, but error code not displayed after messaged flashed. Dealer replaced #1 fuel injector. Motor will intermittently idle rough once the motor is warmed up. Also high speed stalling. Tends to occur when the outside temp is 65+ degrees. Has been occuring for 4 months. Dealer has not experianced in three visits for problem.
Camshaft actuator failed, replaced by dealer.
Cylinder head replaced for rough idle and high speed stalling. Valve guides for Cylinder # 1 worn out. Leak down test was at 80%. Problem reoccurred within 40 miles of getting car back, with rough idle even worse than before. That is it, I gave up and traded the car in.
2.4L engine is mysteriously losing coolant. Did pressure and cylinder tests, could not find any reason for the problem (though the engine continues to lose coolant). Check engine light; dealer claims error code indicating poor fuel. Added octane booster, reset light, suggested I use better quality fuel.
Different dealer discovered leak in Cylinder #3 due to cracked head gasket and head warped. Head and head gasket replaced. Coolant loss still evident after head gasket replacement. Additional tests indicated porosity in the engine block casting; GM decided on a complete engine replacement.
Could not remove key from ignition . Ignition sensor had to be replaced .
Output speed sensor was replaced. Car would shift hard when accelerating. The car was losing track of the speed and the transmission didn't know how to act.
Check engine light came on intermitantly. Took to dealership and they diagnosed a shorted intake solenoid. Replaced cam solenoid. No cost to me. Covered by powertrain warrenty. Less than 3 hours to repair.
Car failed to start. Was able to start by holding accelerator to the floor. Dealer said it had jumped time because of a broken timing chain tensioner. Replaced tensioner and chain. Had engine light, returned to dealer, they had to replace the exhaust cam actuator solenoid... Again with the cam timing system.
Replaced belt tensioner
Replaced lower exhaust system including catlytic converter
TSB for tranny reflash -- shifting irregular
Replaced the solenoids.
Cracked engine block. Replaced and rebuilt engine.
Problem returns two days later, root cause is the same, cracked block between first and second cylinder. Entire new engine placed in car
Car failed to run. Towed to dealer and diagnosed with a bad map sensor. Replaced for free under emissions warranty.
Replace catalytic converter
CEL/SES reported P0010 code. Took to dealer to replace intake camshaft actuator solenoid valve
and was replaced under power train warranty.
The catalytic converter failed. Symptoms were poor gas mileage and sluggish engine response. There was no other issue with the engine to cause the failure and no trouble codes were showing up. The converter was replaced under warranty.
The engine was making a knocking noise when it shut off (intersections and turning the ignition off). The throttle body was failing and it was replaced at the dealership. Engine now has more power and fuel economy is better.
