2009 Chevrolet Malibu Hybrid power train problems

“My vehicle can overheat at times and the thermostat won’t work. That’s during the summer and winter so the temperature could rise above normal and I wouldn’t know because of the electric problems. It’s happened too many times to count. The ESC sign comes on across the dash for me letting me know there are issues with power steering and traction. I can drive on my way to work and on the highway and it happens randomly. It’s dangerous and scary I have to pull over on the side of the road to turn it off and on. Sometimes more than three to four times before it acts normal again. I tried to go to GM because my car has the symptoms of the cars being repaired in the recalls. But I’m told there are none for my car but yet the car still locks on me. It jumps too as it’s accelerating.”

“The car suddenly turns off while driving shutting down the power steering making it difficult or impossible to maneuver. It is a death trap. This happened 3 times today May 5, 2023 Losing power while driving is a major safety issue that is putting innocent people's lives at risk.”

“I purchased the car used and been driving one week. I was driving at approx 55-60 and attempted to accelerate going over hill. The car rpm went up to about 3000 and was reving high until I let of gas. I attempted again to push pedal which repeated same acceleration of rpm. I stopped and checked Trans fluid and oil both were fine. Pulled into drive and turned off ignition to check fluids again. Which were ok. Got back in car to move and had no reverse. Car would slowly go forward but Nothing else. In searching onstar ran codes and I found info about 3/5-r wave plate “service bulletin”. Had car towed to dealer who confirmed and said metal flakes in tranny and was due to “common issue of wave plate” Contacted gm several times and gm will not cover cost of tranny replacement because my car is inoperable. This is a “common problem” with 09 Malibu. Why isn’t it recalled tranny. Very sad I feel I’ll never buy a Chevy/gm product again”

“Transission was recalled by GMC, however my VIN# was not included. I was told to contact you to include the VIN# in the recall. I paid $3300 to repair the transmission only to be told after the fact I need to contact NHTSA to include.”
