5 Vehicle Speed Control problem

Failure Date: 08/01/2024

My vehicle will not shut off. It states "shift to park". Sometimes it takes 30 minutes of trying to get the car to shut off. Since this began, we were on a road trip, it's causing issues with accelerating on the highway & I believe it's damaging the transmission. 2020 chevy Malibu had other models under recall for this same reason. I called chevy dealership & they said they cannot help me. They told me to contact general motors. I have a 8 month baby, I'm a single mom & lost my job after maternity leave. This should be resolved as it's causing me anxiety to drive it with my child in the car. Please help me.

6 Vehicle Speed Control problem

Failure Date: 04/28/2023

While driving on many occasions the last incident happened Friday April 28th 2023. My 2020 Malibu lost all communication on 231 hwy. All dash gauges went haywire power dropped on vehicle rpm was accelerated but vehicle speed would not change engine light and traction light came on. I then had to pull over brakes made a loud thud noise when stopping. Turned vehicle off sat for about 15 minutes and restarted my vehicle engine light was still on but I was about four miles from home turned my hazard flashers on and made it home. When the car loses power it gives me no warning at all it just happens. I've taken it to both chevy dealers in my area mr. Matthew at gilland GMC ozark, al explained to me that yes he saw the codes where car lost power and because they couldn't pinpoint the problem GMC had to be called and he was told that GMC has a team of engineers working on the loss of control problem but at this time they don't know anything. I'm risking my life on every day driving this vehicle in which I do have an extended warranty on but they can't fix what they can't find but yet know for fact that there is a problem.

7 Vehicle Speed Control problem

Failure Date: 02/16/2023

Vehicle through a "service engine" and lost partial power. The vehicle slowed considerably and was not able to accelerate as expected. Fortunately, this was rush hour traffic and it was slow. Normally, the traffic moves at 60 mph plus or minus 5 mph. The loss of power on i10 can be extremely unsafe. The dealer revealed that our car had a scan code p0299. They cleaned the thottle body and stated it was the likely problem. However, they said they tested the crank case pressure and it was at 0 psi, instead of the expected vacuum. There was no indication, that crank case pressure or the pcv was the root problem. I pointed out that crank case should be measured in inh2o. I think they mis diaganosed and were trying to lead me to replace the pcv, and ultimately the turbocharger itself. I think it is probably a sensor or perhaps another component. I took my car away from the lot and will report any other incidents or findings.

Shift to park error, no power to car, reduced engine power, camshaft positioning error, brakes failed (completely went hard unable to press) almost causing crash.

9 Vehicle Speed Control problem

Failure Date: 10/23/2022

Since last year I am having this problem in this car, even after parking the car, it is giving an error of "shift to park', I have already taken it to the car dealership twice to fix this problem and still the problem is not getting fixed in the car. Not even that I live in California and while coming back from vegas last year, this car suddenly stopped working while on the freeway, luckily I was near truck station so I stopped the car. This is a new car and I didn't even drive 36000 miles on it and it is giving me problems. This car is a serious problem and I would request NHTSA to please step in and take action regarding the manufacturers.

10 Vehicle Speed Control problem

Failure Date: 12/23/2021

This issue started at approximately 19,500 miles. While accelerating to enter a highway or to pass a vehicle going less than 55mph on a two-lane, service esc light appeared on dash. Loss or power was also immediate and if I tried to accelerate to maintain speed, engine was very rough in responding with no acceleration. Engine continued to run. Within 30 seconds or so, acceleration is restored, and check-engine light was flashing. Check-engine light stopped flashing after a minute or so. Initially, this only occurred occasionally during fast acceleration as mentioned above. Lately this has happened during continuous acceleration, such as using cruise control, while climbing a low incline hill (~15?). Over the past year or so, chevy dealer has replaced, pistons, fuel injector, and did a carbon cleaning of engine. No solution yet.

11 Vehicle Speed Control problem

Failure Date: 10/23/2021

Was traveling at about 58 mph down the highway when all my warning gauges starting going off. My digital dash went blank and the car started accelerating on its own. I kept hitting the brakes trying to make it slow down and I could hear the abs function and feel it thru the brake while trying to slow down. After about a 1/2 mile of fighting the car the dash turned back on the check engine light stayed on and the car stopped trying to accelerate but wouldn’t change gears and was stuck at 3500 rpms when I limped it off the road and had a tow truck come get it.
