Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure...especially at a high speed like I was driving.

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 car shuddered on initial start-up, turned it off waited for a minute. Restarted ran normally. The next day on start-up dic alerted to ABS, powersteering, and stabilitack in need of service, noticeable difference in steering control, wheel slippage on quick exhilaration, I tried to brake more cautiously so as not to test my braking ability. Definitely a safety issue. Should be recalled. Had the same problem a year ago spending $495. To have the opposite wheel hub and brg assembly. Hope this isn't an annual event. Love my car but hate expenses that should not occur with a car; especially under 100,000 miles. Why did this happen? There is nothing to blame it on such as hitting a pothole. The weather has been colder, there has been a reference to that as well as some say it is a wiring harness that is in a bad location, wearing exposing wires that make contact with metal. Research shows that other drivers are having the same issue and expense. How many complaints will it take before this safety issue is addressed and customers are refunded this unnecessary expense

Stabiltrak ABS traction control warning lights all come on vehicle shudders and power is reduced. Researched and found 100's of reports of the same issue with the impala and similar complaints in the light truck and SUV models. Fix is relatively inexpensive if your mechanically / electrically inclined as involves splicing in a new wire harness for the ABS sensor. Said harness is about $20 it shorts out due to insufficient gauge of wire used on original factory install. Replace harness has much sturdier gauge from what my research says. Repair shop quoted $700 to repair glad I told them to put it back together. They have a fleet of impalas as loaners so they know they are gouging people when they say replace wheel hub assembly ABS sensor and wiring harness when they know it's the ABS sensor period. Chevy needs to do a recall. Issue happens when car is in motion after turning or going over a bump wiring that has been wore thru due to placement of wiring in a high friction area, wire wears through coating exposes wiring that shorts out and sends codes to computer concerning ABS stabiltrak and traction assist causes vehicle to behave erratically others have reported caused vehicle to stall and not restart until problem corrected. I'm sure they are gouged for a thousand $ or more. Wet road conditions,extreme heat or cold,left turn while backing, jarring bumps, all trigger the dash to light up like christmas tree dinging alarm goes off steering shudders power is reduced. It's a huge distraction and safety concern for so many to be experiencing gm should stand up and take care of the problem.
