Filed Jul 25, 2023 · Engine · 62,000 miles · WI

The contact owns a 2017 Chevrolet Cruze. The contact stated that while driving approximately 40-45 MPH, the check engine warning light illuminated and the vehicle decelerated to 30-35 MPH. Additionally, the vehicle made abnormal rattling sounds and failed to exceed 30-35 MPH. The vehicle was taken to the dealer, where it was diagnosed that the knock sensors needed to be replaced. The vehicle was repaired; however, the failure recurred two months later. The vehicle was taken back to the dealer, where the knock sensors and the engine were replaced; however, the failure persisted. The vehicle was taken to a second dealer, Zimbrick Chevrolet Service (1877 W Main St #200, Sun Prairie, WI 53590), where the knock sensors and the knock sensors terminal were replaced; however, the failure recurred. The vehicle was taken back to the dealer, where it was diagnosed that the Engine Control Module (ECM) needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the vehicle was out of warranty. The failure mileage was approximately 62,000.

Have filed an earlier complaint and never heard back. But the engine was stalling and not maintaining speed without heavy acceleration. First week of August 2022 the car finally gave out after diagnosis of faulty knock sensor. Was displaying knock sensor code intermittently and finally stayed on. Anyway first week of august it stalled completely at a stop sign and would not crank back up. I finally started checking relays and found the engine functions relay faulty by accident. There are two square grey relays under the hood in the fuse block. One says engine function s relay and one says something to do with defrost controls. Had to swap the two relays to get my car running. No problems since. Only had 87,000 miles on car.

Faulty knock sensor at 83k miles. First symptoms were slow/jerky acceleration and needing to apply more pressure to the gas pedal to maintain speed, followed by illuminated Check engine light that came on a few days later. The scanner at Autozone pulled the code P0325. Improper detonation regulation is dangerous. This vehicle has been well maintained but needed all four pistons replaced after 60k miles and the cause of the piston damage is unknown. In this vehicle’s history is also intermittent stalling and the vehicle turning completely off after idling, but dealership could not reproduce either issue. Those problems appeared early in the vehicle’s life/well within warranty.

Cylinder 1 experienced cracking due to Low Speed Pre-Ignition (LSPI, commonly referred to as “Knock”) just after exiting the highway in a 70 mph zone and produced a Malfunction Indicator Lamp (MIL) code of P0301. As evidenced in Attachment 1, this caused damage to the Antilock Braking System due to loss of vacuum on the system and possible fouling due to foreign object damage to the vehicle ABS. Later assessment by trained mechanics determined the root cause was due to insufficient structural capability of engine pistons to withstand brief periods of LSPI. As evidenced by attachment 18-NA-171 and PIP5490, the vehicle manufacturer (General Motors) is aware of the insufficient design of the pistons, has re-designed them to withstand LSPI, however has not made an effort to notify me or replace the existing part to prevent damage to the vehicle powertrain and ABS. While this particular instance of piston cracking due to LSPI has only had a financial impact on myself, loss of ABS functionality and potential engine seizure at highway speeds have the potential to produce dangerous, if not fatal, conditions to other drivers with similar hardware.

This is for the knock sensor I have changed it 5 times it will last maybe a month or at the longest 2 months and it will throw the check eng. Light on again I have called the dealership they say there's no recalls yet and when this happens if u take off slow it will shift fine but if you try to go and get on the highway and get up to speed fast the rpms will go up real high and not wanna shift very well. This just happen to my wife's car again today and its the knock sensor I have already put my computer on it and that's what is coming up on it . We have 2 of these cars both 2017 chevy cruze lt 1.4 turbo and hers is the only one acting up.

The vehicle has been in motion at any speed... When pressing on the gas"throttle all the way down" vehicle has a brief interruption of acceleration and check engine light comes on reporting code p0325. Engine knocks/shakes and lose acceleration and reduced power for over 50+ miles after each incident. I have had the engine repaired twice and rebuilt. Ecm has been reprogrammed and gm flew a engineer to troubleshoot I am again having problems 10k miles more and this is ongoing and dangerous. Please please investigate this as gm has not taken ownership of this defect. If you would like all 10+ service records related to this I am more than happy to share and onstar has preformed vehicle diagnostics after each instance. What ever you need please let me know! Thanks for all that you do! There were a multitude of instances vehicals engine was rebuilt/replaced at 7k again at 14k and now at 40k power train is showing same signs and symptoms of previous issues

I get near the paulsboro exit when I hear the knocking again I get to the exit and my power steering isnt working so I forcefully turn the wheel to pull over I turn on my hazards on pop the hood and I see my serpentine belt is off the rotation track and I get my phone and use the light and see the alternator hanging by a wire hanging underneath my car. I called chevy told them what happened to my car they towed my car to chevy certified mechanics I asked how did this happen and nobody knows why my 2017 car tried to kill me on 295
