Without warning oil consumption went from normal to over 1 quart per 1000 miles. This is a known defect whichtoyota notified its customers of, GM choose not to notify. This excessive consumption, not leaking resulted in a seized engine. GM is not accepting any responsibility and I believe they owe me either a full repair, or pre-event market value. While they originally offered to cover 2/3 of the repair they have backed away from that offer offering a $2500 customer loyalty on a purchase, both are unsatisfactory to me, as they were made aware of the problem and chose not to notify owners. Car with passenger was in the hoa lane when engine failed causing a 7 lane transition without power. Car was towed, no crash due to the experience of the driver.

Excessive oil consumption with the 2.4 liter engine

- Utica, NY, USA

For the past year, the vehicle has exhibited excessive oil consumption requiring one quart of oil per every 1000 miles. Consumption is greater in the winter (closer to one quart every 800 miles). This vehicle is equipped with the 2.4 liter engine - the same as the Toyota matrix and corolla. Toyota has issued a warranty enhancement (ZE7) and tsb recognizing this defect - so far GM has not done anything. (I have been in contact with GM.) at a minimun, GM should match Toyota's actions. The estimated repair cost to replace the pistons/rings with a better design is >$4000.

The dashboard warning lights came on. The lights did not provide enough warning time to allow my husband to pull off the interstate (and turn off the car) before the engine overheated and was destroyed because of a damaged water pump. The vehicle was serviced on the same day (transmission drain/fill and tire rotation) and there was no earlier warning that there was an issue with the water pump.

Intermittent, but increasingly frequent engine stalls at highway speeds and slower speeds. Stalls may happen at cruising speed or when decelerating or accelerating. Occasionally, engine races or chokes. Usually requires turning the key to off and then restarting the engine in neutral or park. Similar problems as experienced by owners of 2005-08 Toyota matrix and Pontiac Vibes who had the ECM recalled. This ECM replaced under warranty on 6-3-14. Recall of 09 and newer models may be warranted to prevent dangerous crashes and rear-end accidents.

The engine stopped at freeway speed. This was the sixth time that this happened over a period of about a year. Once off the freeway and stopped, the car does restart. I have taken it to a dealer, but they did not do an official inspection since there were no codes and the car was running fine. This was just after the car had dies on the freeway in December. That was about the fourth occurrence. They suggested cleaning the battery terminals which were a little corroded. I did this and installed a new battery. The stalling has happened twice since. I have been talking to GM customer service and their suggestion is that I pay to have diagnostics done at a dealership. This is a statement from their chat: However, we can see what assistance is available, however, given having over 100,000 miles does limit what we can do. Ok, so you're not allowing us an opportunity to look into this further. 12:32:34leaundre:I can document this concern in our system. The specialist will do nothing further unless I pay to have the diagnosis done on the car.
