During braking, the car will sometimes lurch forward due to the transmission downshifting hard. The feeling created is like being hit in the rest by another car at low speed. This could cause the vehicle to rear-end another vehicle or cause an accident at intersections containing crosswalks and pedestrians.

This car has been a lemon since we owned it. First the electrical system shut down (while we were driving at 70 mph), then the wheel barrings needed replacing at 60,000 miles, and now the solenoid has gone bad preventing the car from shifting.

Warning indicator lights began flashing on the dash and warning lights in the mirrors flashed randomly. GM dealer said it was a sensor that water had leaked in and corroded inside. Said it was safe to drive and would take a week to get the part. The next day it shut off after about one minute when started with the remote start. When driving on the street more indicator warnings came on: Airbag, traction control, parking brake, etc.; the A/C came on by itself; the headlights, heater, and turn signals stopped working. Stopped the car and shut it off for about an hour. After starting it with the key and running it for about 3 minutes, it shut itself off. Once started again, would only move about a foot and then stopped sharply, like the brakes had been slammed on. Did this several times. Parked it again and had it towed to the dealer. They still say it's the sensor problem and will be $1200 to fix. They did not investigate the issue further although it is clearly a safety problem.

June 2016 at 20K miles the car was erratically shifting at 30-35 mph and had a bad smell from the vents. I brought it to bonner Chevrolet who stated they were unable to replicate the issue and it may be due to running too high of an octane of fuel. The issue was not resolved. October 2016 I brought it back to the dealership for the same issue but I also noticed a slight ticking noise. A motor mount was changed but nothing was done about the shifting issue or bad smell. They stated because the car was not giving any codes, there was nothing else they could do about it. August 13 2017 at 25 or 30 mph while accelerating the car violently jerked my son and I forward. It also did this while downshifting. It continued to do this for 5 minutes until it began to no longer shift gears. The check engine light came on. It got to 4500rpm when I pulled over and shut the car off. I turned it back on after a few minutes but the issue continued. After another 5 minutes I got home. Monday 8/14 after arguing with Chevy about towing my car since they didnt want to pick it up until 8/17, they agreed to pick it up that day 8/14. They also stated I would get a rental as long as it was determined the issue was a failure on behalf of Chevy and not myself. Tuesday 8/15 came with no update from the dealsership. Wednesday morning 8/16 I called for an update and was informed the car had "internal engine failure". the service rep paul at valley Chevrolet refused to give me the code the car was giving for the internal engine failure. He refused to give me a rental because the car has over 36K miles. I informed him this is conflicting from what I was told on 8/14 by customer service. He said that if I did not want the car fixed, that he could leave my car outside. No call back yet from customer service as the rental and transmission replacement should be covered under the powertrain warantee.

On 12/21/16 while merging onto interstate 10 in tucson, AZ, the vehicle was going approximately 65 mph when a "engine power reduced" sign popped up, the vehicle slowed down to 30 mph without warning and shifting down through all gears nearly red lining the rpms and causing an rear-end collision. Was able to move the vehicle off the freeway and took it into local auto-zone for testing. The test came back as a "throttle sensor malfunction". the vehicle now doesn't feel safe to drive, and will not accelerate over 45 mph without shaking and feeling like the transmission is going to give out. Called the local Chevy dealership and was told the cost was going to vary between $400-1,000 with a $100 test fee up front. I've also read numerous similar issues online from people driving Chevrolet Impala from 2006-2016. The car feel very unsafe to drive and I feel it could be a death trap as there is no control over when the vehicle will choose to decelerate without warning. There has been no mechanical issues before this incident, and the vehicle has been through numerous mechanical maintenance up-keeps that were recommended by service managers.
