2017 Chevrolet Cruze

My 2017 Chevy Cruze had the throttle body replaced by STG Auto Group in Montclair, CA. A few months after the repair, my car began shaking violently and then shut off in the middle of the street while I was driving on 11/17/2025 This created a serious safety hazard for me and other drivers. When I took the vehicle to a local auto zone once the vehicle turned on , they told me the throttle body “needs cleaning,” but a new throttle body should not get dirty within a few months. This suggests improper installation or a defective part. The problem returned even though the part was recently replaced. I immediately called the dealership who fixed it and the manager stated I’d have to wait to the following week for another inspection and that I can not be squeezed in . The vehicle is still unsafe to drive because it shakes and can stall unexpectedly. I am concerned because this issue has happened more than once and could have caused an accident.

Apparently there is a TSB from GM regarding the end for updated/replacement of parts concerning the hydraulic piping, slave cylinder and accumulator. My clutch became spongy then stuck on the floor. This happened unexpectedly (reservoir full) while driving and almost caused an accident. Apparently GM doesn't take enough accountability to update the failure before or after failure. Reporting this hoping it will eventually force a recall!

Slave cylinder failure. At approximately 125,000 miles, the slave cylinder began to fail. Clutch pedal would only come back up about half way, and would need to be pulled the rest of the way up. Associated problem is difficulty putting car into gear. Took vehicle to dealership for other warranty work and asked to investigate. Dealership ignored request. Took back separate time for other faulty parts and was ignored again. Other part failure was turbo waste gate. Internal spring failure caused turbo waste gate to become stuck open, not allowing boost to build. Caused check engine light and severe lack of power. Replaced part with aftermarket, and problem disappeared. Investigation into cause revealed low quality spring that broke internally. Dealership visits within extended warranty period were ignored/ told could not replicate issue, despite suggestions of potential causes, including waste gate failure.

Once my Chevrolet Cruze equipped with the 1.6liter diesel engine and 9T50 transmission reached 120,000 miles it stopped shifting into the 9th speed. I had Jones Chevrolet (local GM dealer) flush the transmission at their request. Apparently the transmission filter is basically impossible to replace unless pulling the transmission out and taking the transmission apart. This problem still exists and after doing some research it seems that GM knows of the problem and changed the torque converter and transmission pump in later years.

The slave cylinder failed in the manual transmission. When it failed, the petal went to the floor and did not return. In a panic I was trying to engage it, the vehicle was rolling without control of the drivetrain. I pulled into a driveway and rolled out into traffic when trying to put it in reverse and was not able to move the vehicle. Yes you can inspect it currently being repaired for $1500

To whom it may concern, I am writing to express my deep disappointment and frustration regarding my recent experience with my 2017 Chevrolet Cruze. It has come to my attention that there is a known issue with the piston in the engine of this model, and unfortunately, I have fallen victim to it. This issue has caused significant inconvenience and expense for me. As a loyal Chevrolet customer, I expect better quality and reliability from your vehicles. I urge you to address this matter promptly and take responsibility for the faulty piston in the engine of the 2017 Chevrolet Cruze. I trust that you will take appropriate action to rectify this situation and restore my confidence in your brand. Case # 9-12557961076

Based off my mechanic's assessment and that of a Chevrolet dealership, one of the cylinders in my Chevy Cruze is no longer firing. The dealership believes at least one of the pistons needs to be replaced. The car is available for inspection. The car is unreliable to drive, as I drove up a freeway incline it slowed to a dangerously low speed for freeway driving. The dealership has confirmed they believe it is an issue with the piston but will not confirm without charging $2800 to dismantle the car and are not able to guarantee they will be able to fix the issue. Diagnostics were run on the car at Putnam Chevrolet in Burlingame CA. There were no warning lamps or messages prior to a major issue with the cars functionality. The issue first appeared June 15, 2023 without any warning. The engine light came on and the car was not functioning properly, plus a notification to "service Stabilitrek". I have found mention of the same problem on consumer forums. Cracked pistons are a KNOWN issue on this make and model but there are no recalls and the car is just outside of the warranty.

The contact owns a 2017 Chevrolet Cruze. The contact stated that the vehicle was designed with the Auto START/STOP feature; however, while at a complete stop, the engine turned off but failed to restart. The contact shifted into park (P) and restarted the vehicle. The contact stated that the failure occurred intermittently. Additionally, the contact stated that while driving between 35-65 MPH and depressing the accelerator pedal, the vehicle jolted and hesitated to respond. The contact stated that the failure occurred intermittently. The contact also stated that the check engine warning light illuminated intermittently. The vehicle was taken to an independent mechanic, where it was diagnosed but no issues were found. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 42,000.

Car very suddenly started having slow acceleration, and vibration felt during acceleration. Check engine light on with StabiliTrak warning message on dashboard. Rough idle and vibration felt in cabin. Difficulty accelerating at traffic light and car seemed to almost stall at one point. Diagnosed at the dealer with cracked pistons in engine with code P0300 for random misfire. 2017 Chevy Cruz has passed the power train warranty by 1 year. Mileage odometer reading is about 58200. GM is not willing to replace without charging $4700 for replacing the faulty piston components in the engine even though this poses safety hazard for regular driving. After some research, this seems to be a widely known problem of this generation Chevy Cruz and GM has even changed the part number of the piston assembly to replace the faulty pistons in engine. This needs to be a recall!
