2012 Chevrolet Impala transmission complaints
Page 2 of 2: complaints 11 to 27 of 27, newest first, as owners wrote them.
Grinding noise from front and momentary loss of acceleration upon acceleration from stop. Most prevalent on left turn from stop but progressively getting more frequent on straight or right turns. Dash traction control light illuminates momentarily. Original dealer inspection found no issue. On star diagnostics revealed nothing. Above 5mph no symptoms at all. Dealer will reinspect next week.
When backing out of parking space turning right and then turning left, it sounds like grinding metal and the car starts jerking until the wheels are turned straight and then it's ok again it is really loud. I took it to the dealer but it wouldn't do it for them.
Clunking sound from transmission differential...when you pull out from a stop you get a clucking noise and the car cannot go...something is grabbed..pulling onto a city street or going in reverse from driveway..mechanic has been unable to find problem after 5 attempts.
Gm service bulletin id: 3650687.
Car cut offs when put into drive car cuts off while driving. Rpm odometer stops working. Check engine light comes on reduce engine power. Stability track and ABS stop car from turning. Gm dealer said its battery terminal wires and a new battery changed both and same issue. Fuel pressure sensor keeps going bad replaced twice. Car is choking on to much fuel rotten eggs smell coming from exhaust. Car is very dangerous to drive has cut off on me in traffic to many times now. Once and if problems are ever found their needs to be a recall to prevent injury or death.
Accelerator response time takes too long to re-accelerate . After letting off gas then re-applying pedal while driving, response time should be 800 mili seconds for an electronic accelerator but , it is way longer and makes car backfire at times if I hold pedal after the lag in response . This causes car to lunge and could cause me to get rear ended or damage engine. Second, rubbing grinding noise (not loud) from right front and more noticeable while traveling at 35-40 MPH around a left bend in road or by moving steering wheel to left about an inch while driving straight down road. Dealer claimed no problem found on either issue , although they claimed to have replaced a strut bearing on right front. There must have been a previous issue judging by the worn tire before I purchased car. I figured it was an alignment problem that may have been fixed because car didn't pull to one side and drove straight , but apparently there is still an issue and noise is slowly getting more noticeable unless I'm just tuned into it.
Replaced front wheel drive intermediate shaft and right side transaxle seal.
Front wheel hub and cv axle nut loose. Replaced front wheel hub part # 88964168, hub 6.307 qy* cpobk. Torqued right front wheel hub and cv axle nut to specifications. Gmc factory error in quality control.
Failed torque converter. The torque converter would slip when shifting from reverse to forward (drive). It would slam into drive, grin the gears and cause the tires to squeak (spin). On april 28, hedrick's chevrolet 961 w shaw, clovis, ca, replaced the original torque converter, with a remanufactured convertor, part number 17804457 (1), plus the following parts:17804457(1)-core return, 24264377 (1)- seal kit, 25886620(2)- gasket,10333578(1) - gasket, 12609163(1) - gasket. It is a warranty clovered part.

While driving in the far right lane my dashboard went completely black,the radio went off and my steering wheel was extremely difficult to turn.I was able to maneuver the car to sidewalk the car was still in drive the keys were in ignition. I turned the key and attempted to restart the car it made a terrible banging clunking noise.I called the dealer and told them waited 15 minutes later the car started.ths really needs to be investigated as I could have caused are been involved in a accident. I'm very afraid to drive my car. I took the car in later to dealer they kept it until friday provided me a loaner they claimed they drove it and it didn't act up. But its not like they drove it all day I'm extremely upset and disappointed in this matter. I feel they discounted what I said.this could occur while a teenager are elderly person is driving. Please please look into this matter.
At times, the vehicle jerks while shifting. I have experienced heavy jolting, rough shifting, especially during low speeds. While on highway or during strong acceleration, car shifts great. Mostly the issues are during downshifts or low speed shifts. Took to chevrolet dealership, was told a factory reset may help adjust to driving styles. We bought car used with 35000 miles. This did not help. Not even sure if this is an option. No check engine lights or anything. Dealership cannot locate problem. Says transmission takes some getting used to. Awesome car, just wish this problem was corrected.
At speeds 15 MPH and above after decelerating then accelerating transmission will make a noise ranging from a clink, clank, clunk to a banging jolt as if the car has been rear ended. The more pressure on acceleration and the lower the gear the louder the noise and the greater the jolt. Dealership states transmission is operating properly.
