The contact owns a 2003 Oldsmobile alera. The contact stated that while driving at approximately 10 mph, the temperature gauge increased and white smoke or mist emitted from the exhaust pipe. The check engine warning light illuminated. The vehicle was taken to an independent mechanic who stated that the engine block was cracked and recommended that the vehicle be taken to a radiator specialist, who diagnosed that there was a crack in the block and the engine manifold. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 215,015. The VIN was not available.....updated 07/05/16

I used my horn to let someone know that they were in my lane, and all of a sudden my horn was stuck. The window clips on my car broke off, as I have read of these same complaints of other 2003 Oldsmobile Alero owners. I believe that there are serious defects of these two parts, and GM will not issue a recall to fix these problems. Due to that fact, I am unable to pass inspection because my car has to have a working horn and my window must be able to move up and down. Also a third complaint, there is now coolant that is starting to leak into my oil, which from what I understand could cause a fire!!

The vehicle dies. While cruising at any speed, the hydraulic brakes & steering failed due to the engine dying. There is no set pattern, it might stall 6 times in one day, then twice the next day. Then go 4 days with no ocurrence, then it will stall once a day for 3 days. Then go a week with no ocurrence, then stall 4 times a day for 5 days, etc., etc. In every ocurrence, it takes approximately 10 minutes before it will start back up. At high speeds, it is extremely too dangerous to drive. We've taken it to the dealer, under extended warranty, the required 4 times under the lemon law process. The dealer cannot ascertain, nor fix the problem. It happened to the dealer at least once when we took it in. I doubt they will admit it, however, my wife was witness. The car is a 2003. Even though I bought it in July 2003, it was considered a used car. GM has denied our claim since the lemon law does not apply to used cars. The car has been permanently parked since November 2003. We were forced to buy another car. The dealer would not trade. This has resulted in a badluck situation for us. We cannot afford 2 car payments / 2 insurance premiums, nor can we afford $300 per hour to sue GM. I stopped making payments in December 2003. I have kept the finance company abreast of the situation. They have not repossed as of yet. They want me to try to sell it. Can you help ?
