Additionally, the vehicle lost motive power while driving 60-70 MPH and decelerated to 10 MPH. The engine revved while stopped at a red light, and the RPM was at HIGH. The check engine warning light was illuminated. The contact stated that the vehicle was taken to the dealer on six occasions for the recurring failure. The contact stated that DTC: P0401 and P0521 were retrieved and cleared after securing the air box cover after the first failure.

The fourth time, an unknown sensor and module were replaced. The fifth time, the dealer replaced the transmission with a used transmission, but the failure persisted. The vehicle was then taken back to the dealer, and it was determined that the driver's side CV axle seal, NOx sensor 1, MAF sensor, passenger side front wheel bearing, two front tires, four TPMS, intake manifold, and air temperature sensor mount needed to be replaced.

The transmission system failed abruptly. I pulled away from a stoplight, had accelerated to 20-25 mph, and then the car came to a sudden stop, as if someone had put on an emergency brake. It continued to act as if the brake was on when I tried to go forward or reverse. I put it into neutral so that I could push it off the road. I realized it would drive slowly in neutral, so I drove it less than a mile back to my workplace. Regarding safety, I nearly got rear-ended when the car stopped suddenly. This endangered me and the other driver. I was headed to the freeway, then would have been crossing a bridge, to get home, so the danger could have been amplified. The dealership's service manager told me that something internally had failed in the transmission. As far as I know they haven't taken it apart to find out what internally failed. They told me that the transmission needed to be replaced. As far as I know, no one has inspected the internal components of the transmission. There were no warning lamps, messages, or symptoms prior to this incident.

On Sunday, [XXX] (a very hot day in Michigan. My vehicle registered 100 degrees) I was driving on [XXX] about 70-73 mph when I got an alert that said (to the best of my recollection) TOO HOT - IDLE IMMEDIATELY! and there was a continuous high pitch beeping which I only heard after turning off the radio. I continued at highway speed for a good 2-3 miles to the next exit afraid at any minute my car would start smoking. I exited and had to stop at a red light before turning left into a Kroger plaza with a fuel station. When the light turned green I accelerated and a grinding sound came from my car. I pulled into the plaza and turned the car off but had to turn it back on in about a minute as it was too hot to sit in car without air conditioning. It started and idled just fine. I googled roadside service and got a nice fellow (on a SUNDAY!) and he arrived in about 40 minutes. He towed me 40 miles away to a recommended auto shop that on Monday told me it was my transmission cooler that was defective and that I needed a transmission shop for a new transmission. It was then towed another 20 minutes away where it stayed for 9 days. Cost: $6564.48 plus $150 for paying with a credit card so totaled $6714.48. My drive train warranty was only good to 60,000 miles/5 years and I have 76,000 miles on my car at the time. Was told the transmission cooler was defective so I asked to have the cooler part and I have it in my garage. I spent over $1000 at the dealership in the months of Feb/March/April 2025 as my car hit the 70,000 mile mark so I had them do all work required by the car manual. The transmission cooler is apparently not a part they check. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Symptoms were poor gas mileage, highly rough idle (especially in DRIVE, while at a stop), lag in acceleration as well as delayed response to gas pedal depression, struggled take off from an incline while utilizing AC on high output. Diagnosed by a code reader with confirmation by a trusted mechanic that the transmission is malfunctioning. Mechanic indicates the need to seek a shop specializing in transmissions because this entails disassembly of drain pan and plug to find issue either with fluid seal or the start/stop assembly in relation to the transmission. Issues began approximately 6 months ago, as I have been trying to deduce the issue by process of elimination by way of services and mileage recommendation. All professional involved indicate that a Chevy at this mileage and age do not typically display concerns related to the transmission.

To Whom It May Concern, I'm writing to formally report a critical failure of the Auto Start-Stop system in my 2019 Chevy Equinox that occurred today, resulting in a hazardous situation during rush hour traffic. While stopped in the northbound left turn lane of Route 202 at the intersection with Baltimore Pike, the vehicle’s Auto Start-Stop feature engaged as expected. However, upon releasing the brake to proceed, the engine failed to restart, and the vehicle remained completely inoperative — engine off, no power, and unresponsive to ignition attempts. This failure caused the vehicle to become stranded in a live intersection during heavy traffic, posing a serious safety risk not only to myself but also to other motorists. A Pennsylvania State Police officer arrived on the scene and assisted by pushing the vehicle across three active lanes of traffic while in neutral, performing a battery jump with a brand new battery of five months, and escorting me home to ensure I was safe. This situation was both dangerous and unacceptable, especially considering that the failure stemmed from a system designed for emissions/fuel efficiency, not safety. The Auto Start-Stop feature in this vehicle clearly introduces critical failure points without adequate redundancy or reliability, particularly in real-world driving conditions. Additionally, I contacted my local Chevrolet dealership and spoke directly with a technician in the service department. He confirmed that they have had multiple customers reporting similar failures with the Auto Start-Stop system. According to him, this is not an isolated incident, and in several cases, it has placed drivers in equal danger. I am formally requesting: An investigation into this incident, Information on any existing Technical Service Bulletins (TSBs) or recalls related to this failure, A full inspection of the vehicle at GM’s expense, And a report on what steps GM is taking to prevent similar failures from putting other drivers in harm’s way.

The vehicle is leaking oil from in between the engine and transmission I am some bit mechanical and im sure its the rear Maine seal leaking yes the vehicle is available for inspection im taking it to H&H chevrolet [XXX] for a inspection I talked to Christian brothers repair and I told them what it was doing and they told me alot about my vehicles problem and gave me some Estimates and also said they have 2 in there shop right now needing the same repair...How was my safety or the safety of others put at risk? well me and my family went out to get a few groceries and it was -25 outside and we almost didn't make it back home because the car was not wanting to drive.if it had died we would have been stuck in dangerously cold weather.no warning lights came on I only found it was leaking when I started to smell burning oil so I looked under it and there was a small puddle of oil. this happened Monday [XXX] and the car hasn't been drivable since it sounds fine but I don't know we haven't moved it since we got it home. this is really inconvenient this vehicle is my only means of transportation to work and I never thought on a car I purchased brand new it would ever blow a rear seal I have heard many other having these problems and I still can't understand why this isn't a recall this is a very expensive problem to just be put on people financially. i hoping GM can resolve this for me.
