Instrument cluster completely blacked out, providing no information on vehicle speed or status of operation. Operation of a vehicle without instrumentation would seem to be a safety risk. Chevy dealer diagnosed problem as IPC error U0155, installed updated software to correct the problem. The repair was not covered by the extended warranty I purchased through General Motors when I bought the car. I think a defect such as this should be the manufacturers responsibility, I believe GM has a service bulletin out for this problem covering several models of their vehicles. This should be upgraded to a recall.

Receiving 3 different errors on dash display. 1) Action Required- No Remote Detected 2) Action Required- No Remote Detected Press Brake to Restart 3) No Remote Key Wa Detected Place Key In Transmitter Pocket Then Start Your Vehicle. All of these errors are intermittent and have appeared with using 2 different Remotes. Batteries have been replaced also. This in itself is not so much a safety hazard (annoying), but what is intermittently happening is the car shuts down while in drive and in reverse. So far it has not shut down on the freeway but has shut down while on City streets. We have taken it to 2 different GM Dealers a total of 7 times in the last 3 months(currently at the dealer now). Each time the dealer is saying they cannot duplicate the errors. We get it back and within 1 (usually the same day)day it is right back with the errors. Clearly these errors are a nuisance and dangerous if the vehicle shuts down. I have additional service documents and photos and videos but due to the maximum I can provide they are not uploaded.

While driving on the highway at speeds above 60 MPH, the engine shut off. There was a slight shuttering immediately prior, but no other indication. I had to pull over, across three lanes of traffic, during rush hour, in a fairly heavy rain and became a disabled vehicle on the shoulder. After being towed to the dealer, it was determined that the fuel pump was faulty. The vehicle had 4,954 miles on it so there was no reason for this part to have failed so early.
I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by Chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it wa…

I went out to start my car and the light said that it was not reading the key fob because of low battery. I went and got the other key fob which had never been used and had the same result. The car was towed by Chevrolet to the dealer and it has been there for over 3 weeks. They found that it wasn't a faulty key fob but it was the receiver that gets the signal and allows the door locks to open and the engine to start. I tried moving the shift lever, stepping on the brakes, trying the remote start on the key fob and nothing would start the car nor would it lock/unlock the doors. It just kept giving me the notice that it couldn't read the key fob. I called ONSTAR and tried the actions they told me but that did not work either and they said to contact my selling dealer. ONSTAR contacted the Chevy warranty number for a tow truck but at 9PM it was too late for them to make a service call. What if I was out in a parking lot or in a remote area and experienced the same problem with no assistance. I have been trying to find out what the dealer is doing to repair my vehicle but I have to call the GM complaint line in order for them to try and contact the dealer about my car. They finally gave me a rental vehicle since the vehicle is less than 1 year old and only has about 6,000 miles on it.

Vehicle now has about 1200 and when driving, the instrument cluster panel that digital shows your speed, odometer and other information on my vehicle went blank. It is just a black screen. When this happened, it caused the steering wheel controls for radio volume and turning the station to not work. With this, I have no safety features like lane assist now and can't tell my tire pressure.
