2017 Chevrolet Cruze

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.

I should have filed a complaint here after the catastrophic failure. The next time I may not be so lucky and it could cause loss of life. I was driving at approx. 65 MPH on the frwy when bang! An explosion under my hood that caused my car to jump over a lane, I slammed on the breaks, swerved but couldn't push the brake pedal down anymore. It felt hard and would barely move. i had no way to slowdown or stop! And traffic infront of me was slowing fast. I put all my weight on that pedal even tried pumping it, but it would only move alittle. Luckily the car in front sped up just enough for me to swerve onto the shoulder. As I slowed i could depress pedal alittle if I stood up on it out of my seat but stopping distance was like 15ft while maybe going 15 mph. This all happened in a matter of minutes i still dont know how I was able to avoid an accident. The engine sounded really rough. So I called the dealership they said to bring the car in. I had already spoke. With them that week due to traction control system and transmission causing instability and brake issues. I was mortified when I found out what happened I had cracked 2 pistons & the force was so strong it blew thru the membrane that seperates the break system, got oil in my break lines! This is a new car! Dealership said it was a known issue & GM determinedtitle was a design flaw. I had 2 pistons replaced and my break system flushed my car has never been the same. There's always something little and intermitten still with the transmission & Now the engine jumps while idling and stopped in drive it jumps so hard the car jumps fwd, feels like ill hit whats in front of me. I lost significant value at only 26,290 miles, i cant afford to trade it in on disability, covid turned into long haul covid, no affordable extended warranty. I have no piece of mind in a car I dont feel safe in. What happens when the pistons fail they didnt fix. How many injuries or lives must be sacrificed before they do something.

Car has a lot of difficulty accelerating even when pressing on the gas all the way to start to go. Car rolls back when stopped. Brakes sometimes aren’t working as they should. Car isn’t breaking properly. Doesn’t stop all the way sometimes. When driving the car also, burning smell comes from under the hood after stopping the car. Please help!

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.

POWER TRAIN, PREMATURE MALFUNCTIONED ENGINE PISTONS, LOW SPEED, CHEVY SHAKE. AVAILABLE FOR INSPECTION AT JOSEPH CHEVROLET ON COLERAIN AVE CINCINNATI, OH. MY SAFETY AND SAFETY OF OTHERS WAS COMPROMISED DUE TO LACK OF EXCELRATION , LOW COMPRESSION.PROBLEM IDENTIFIED BY JOSEPH CHEVROLET DEALER SERVICE WRITER CODY. IDENTIFIED . THE WARNING LIGHTS CAME ON FOR THE STABILITY TRAK AND THE ENGINE APPROXIAMETLY APRIL. 2022.

With no warning the engine 1t through a Stabletrac warning engine code and moments later BIG orange lettered notice showed something to effect of 'extreme low oil turn off engine!' and at the same moment the low oil indicator turned on. We pulled off the freeway immediately and discovered oil all over the engine and of course smoke everywhere - fortunately it did not catch fire. Checking this was a catastrophic loss of ALL the oil. It may be a completely other situation but 1 month previous ~ 1000 miles previous, that same BOGUS stabletrac msg was displayed and the car went on limp mode. Dealer determined very low oil level is cause! NOTE - it does not indicate low oil. It has never consumed oil. It does not drip anywhere and NO smoke. So this is quite a mystery. He reset the codes and serviced the oil. I was due for a formal recheck about now, a 1000 miles later. On this trip (about a 1000 miles I checked the oil level to start and there was full level, so again no indications of consumption. The Vehicle has but 80k miles. There is something very flawed in this engine to fail so early and so catastrophically. Thats dangerous on multiple levels.

The contact owns a 2017 Chevrolet Cruze. The contact stated the service stability trac and check engine warning lights were illuminated on the instrument panel. The vehicle was taken to an independent mechanic where it was diagnosed that the spark plugs, turbo boost sensor, and mass air flow sensor needed to be replaced. The vehicle was repaired; however, the failure recurred a week later. The manufacturer was notified of the failure. The approximate failure mileage was 90,761.

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.

WHEN VEHICLE IS SITTING IN AUTO-STOP MODE, RELEASING THE BRAKE AND PRESSING THE GAS PEDAL WILL RANDOMLY CAUSE VEHICLE TO STALL. I HAVE TAKEN IT TO DIFFERENT CHEVROLET DEALERSHIPS AND NO ONE CAN FIGURE OUT THE CAUSE OF IT AND THEY CANNOT REPLICATE THE ISSUE. (THE MECHANICS ARE NOT DRIVING THE VEHICLE LONG ENOUGH FOR IT TO HAPPEN.) THIS HAPPENS MORE OFTEN DURING SUMMER MONTHS, BUT HAS HAPPENED OVER THE 2020 WINTER. I HAVE TO PUT THE VEHICLE IN PARK, TURN IT OFF AND BACK ON TO GET THE CAR MOVING. THIS IS ESPECIALLY DANGEROUS IF I AM TRYING TO TURN IN FRONT OF ONCOMING TRAFFIC.
