Common Problems with the 2018 Chevrolet Impala

Powertrain, Transmission Issues:

“I have a 2018 Chevrolet Premier Impala that has started skipping gears at 1st and 2nd while driving. The vehicle shudders when it changes gears. Took vehicle to dealer who informed me that the transmission needs to be replaced already. I haven't received any dash messages or vehicle warnings prior to noticing the transmission problem. I always kept the car properly serviced by the dealer for all routine maintenance requirements. I am the original owner of this vehicle. The car has under 100,000 miles. Dealer informs me that it will take at least a week before they can possibly get new transmission for vehicle. I may be without vehicle for at least 2 weeks minimum.”

“The evap core started leaking a month ago had the car for 2 years and as I read online its a common issue and Chevy doesnt want to fix it. Sometimes the transmission shifts hard but doesnt happen often”

“Gears skipping and shruddering between 2nd and 4th gear. Chevrolet dealership recommended engine mounts replaces which was a false diagnose. After further inspection and diagnosing, they revealed that my transmission needs to be replaced for 6200$. I paid the 6200$ and now transmission shifting hard into 2nd gear.”

“Transmission slipping, rough shift and bucking back and forth. Happens intermittently at low speeds and in stop and go traffic as well as highway speeds and when passing.”

Electrical System Problems:

“While driving from work the car did a quick jerk and the STABILITRAK, ABS AND CHECK ENGINE LIGHT ALL CAME ON ALL AT ONCE. As I pulled into my workplace the car lost power to the engine completely while displaying ACTION REQUIRED ON THE LCD SCREEN. The brake and steering wheel became stiff and it was hard to control the vehicle. It took 10 minutes for me to regain power and control over the vehicle that again after leaving work stopped on the highway.”

“2018 Chevrolet Impala. Consumer writes in regards to issues with door locks and tires. The consumer stated the vehicle was sold with 3 worn tires and a key with a dead battery. The consumer was driving the vehicle on a mountain side and extremely heavy fog, the lights (inside and out) went out. The dealer was informed of the failure. The consumer could not replicate the problem, but was unable to start the vehicle. The dealer was unable to repair the vehicle and suggested trading it in. The consumer traded the vehicle in after owning the vehicle for only 8 months.”

“If the car has been operating for long period of time an hour or more when the auto stop kicks on the whole car turns off. Usually at a stop sign or stop light. In the middle of traffic. I have to let it sit off for a couple minutes and restart and jerks hard into gear.. was told it's the battery fuse block and isn't covered by warranty.”

Engine Problems:

“When driving on the highway at full speed my car suddenly loses power almost causing me to be hit from behind. I then get a Reduced Engine Power warning. Once I get the car off the road, I shut the engine off for a few minutes and then restart it. The car runs fine but the check engine lights remains on. This has happen 4 times this week.”

“The contact owns a 2018 Chevrolet Impala. The contact stated that while operating the vehicle, a strange odor was present coming from the engine into cabin of the vehicle. The vehicle was taken to local dealer (raceway Chevrolet located at 1510 South 5th St, hartsville, SC 29550) who diagnosed the air conditioning evaporator coil was defective and had leaked freon. The coil was replaced and the failure was remedied. The manufacturer was notified of the failure. The failure mileage was 39,000.”

“My vehicle has been serviced several times since I have purchased the vehicle. The car will completely shut off when attempting to turn back on after the auto stop turns it off then I have to place the park hit the start switch and restart the vehicle. Also my ac has stopped several times in the vehicle. The ac compressor was replaced in 2019 and had been serviced twice before that happened because it blows extremely low and have to put it on high just for the air to blow. As of today the ac has been going in and out even after the replacement of the compressor and still no one can tell me what's the issue!”

“Stabilitrack and engine light came on at the same time with a message that said, 'engine power is reduced'. this occurred as I was driving on the highway. The vehicle gradually slowed, but I was able to maintain a speed of 55 mph. I was unable to accelerate quickly.”

Brakes Problems:

“Check engine light did not come on when battery was bad.also brakes feel spongy and go to the floor at times, pads and rotors are good.”

“The car was stopped on a parking lot exit ramp. When the car ahead of me moved forward I took my foot of of the brake so I could move forward. When I applied the break to stop, the breaks did not work and I hit the car in front of me.”

“October 10th, I was in an accident where I was literally an entire car length back driving with the flow of traffic at 50-55 mph, when the vehicle in front of me came to an abrupt stop on the freeway. I slammed on my brakes but my car slid straight into the back of the vehicle in front of me. It felt as if my brakes were not stopping my car. I noticed this happening before on a main street and I was travelling at 45 mph but I did not think anything of it at the time.”
