Filed Jan 23, 2026 · Acceleration, Brakes · TX

Car started shaking in the middle of driving it about 30 mph and all the electrical like door locks were going up and down car wasn’t accelerating and an alert came up for stabilizing wheels i believe. It happened for about a couple seconds and then everything went back to normal and randomly happens while I’m driving.Check engine appeared and went to the mechanic shop i usually go to and found out I had ebcm and ecm modules bad. Do some research on the car and noticed it had a recall back in 2014 for EBCM. The problem has resurfaced

Received vehicle at roughly 181,000 miles. Operated fine for about 5,000 miles and then began to show problems. In most cases when pressing down hard on the accelerator pedal, transmission drops into a lower gear and revs up to 5k rpm, cancelling cruise control, and staying there until accelerator is relieved. This makes accelerating more difficult since too much pressure on the accelerator pedal causes the car to get stuck at 5k rpm and stay at the same speed it is already at. This makes passing cars more dangerous as the car gets stuck at 5k rpm and can't pass the other vehicle, increasing the risk of a head on collision. Service engine and ABS lights are on as well as a service Stabilitrak notification in the driver information center. In addition, the outside temperature thermometer is faulty and shows much lower temperatures, such as -14 degrees during an 80 degree day. Vehicle is up to maintenance as far as my knowledge goes. Car has been previously junked twice and has a rebuilt title. There are no fluid leaks, the engine works well when the problem is not encountered, but it gets stuck at 5k rpm under hard acceleration more than it doesn't.

It started off with just a little jerking when I would be in stop and go traffic then it progressed to whenever I was driving below 35mph, the car would completely cut off and the doors would unlock. The check engine light came on and I took it to be repaired. They stated there was a hole in my exhaust which a GM service employee repaired. Two days later the check engine light came on again and this time they stated I needed a new transmission. So I took it to a transmission company, who installed a rebuilt transmission. A few days after getting my car back, the same issue happened again. The transmission company did a diagnostic and stated it wasn't the transmission so I took it back to a GM service place and they stated it was my manifold. I paid for the repairs and the vehicle worked fine until the beginning of April 2022. Now the vehicle is doing the exact same thing expect this time the doors are not unlocking when the car cuts off. A new thing has started where the car shakes when I sit with my foot on the break for too long such as at a traffic light, once I take my foot off the break to accelerate it will jerk or turn completely off. Today, I was trying to do a U-turn and the car just stopped working almost like it was in neutral then the steering wheel locked up.

Driving on interstate after work around 12 am & reduced engine power appears on screen, car slows down & I couldn't accelerate more than 10mph & had to keep pulling over to turn engine on & off. Terrifying! Read other complaints about this just now & needs to be recalled asap before someone is injured or worse especially driving on a busy interstate/highway

This has happened twice now, once for my wife and the second time I was driving. Both incidents happened while in motion on the highway and the vehicle display showed reduced engine power and the vehicle de-rated and slowed automatically on the highway. The check engine light displayed and after connecting a code reader to the obd and code p2138 was logged which is potentially a faulty throttle position sensor/ foot gas pedal. I replaced the throttle position sensor cleared the stored code and a couple weeks later the vehicle again went into limp mode and de-rated on highway. The check engine light came on and the same code p2138 was logged indicating voltage difference between app sensor 1 and app sensor 2 of the throttle positioning sensor. After further research on line I found that a gm service bulletin was issued for potential moisture intrusion of the connectors from the throttle position sensor to the ECM. (see attached) it seems like my vehicle is experiencing moisture in the connectors as both incidents happened within minutes of taking the vehicle through an automatic car wash. In my opinion this is a safety concern for this model vehicle to de-rate and slow down suddenly at highway speeds with cars following behind and has been a known issue by gm and should have a recall issued.

When trying to accelerate to the speed limit while driving on the highway, the car doesn't pick up speed as it should. Driver has to press down on the gas pedal to even get up to speed. And once car is up to speed on the highway, when trying to brake even with new brakes and rotors installed on july 27, 2019 the car tends to continue to accelerate even more instead of stopping. This has happened on numerous occasions since I've gotten the car in march 2018 plus when the auto-stop is initiated the car actually turns completely off turning the radio off but once the brake is released it then restarts. A new battery was installed on march 8, 2019.

I'm driving on a city street with a passenger in the passenger seat and suddenly the air bag light comes on and all of the gauges on the dash board stop working (speedometer/gas) and radio goes black. It happens intermittently and usually only when someone is in the passenger seat. I'm not sure if I lose my headlights as well because I haven't had it happen at night yet.
