| While the vehicle was parked, the consumer noticed oil leaking from underneath the vehicle onto the ground. the consumer noticed while driving the vehicle would shake uncontrollably. the consumer took the vehicle to the dealer for inspection. the mechanic informed the consumer that the oil filter had a hole in it which caused the oil leak. the mechanic also informed the driver that the motor mounts needed to be replaced due to corrosion. please fill in additional information. *jb | |||

| My brother owns a 1997 pontiac sunfire with only 47,000 miles on it and the engine seized (needing engine replaced estimated cost $3,500). i understand the car is about 6 years old but the vehicle is driven minimal miles. gm dealership did a diagnosis costing us $289 and concluded per the invoice: perform tear down on engine - remove valve cover and found valve spring on #2 cylinder broken - remove cylinder head and found head of valve had gone through top of piston and scored cylinder wall. the dealership quoted us cost of the following: $3,250 for a brand new one with a 3 year/75,000 mile warranty or $1,400 for a used engine with 88,000 miles on it (no warranty) or $1,600 for a used engine with 62,000 miles on it (no warranty). now, i scratch my head and wonder how gm justifies us paying almost $1,500 of a used engine with more miles on the engine than the engine we already have at 47,000 miles that does not work. after three weeks we had the vehicle repaired a reputable auto service for $1,089. the auto service suggested taking photos of a part in the engine noted above to be defective. the auto service said this part should never have broken on a vehicle with only 47,000 miles. we informed gm customer service of this defective part and told them about the pictures but gm has done nothing to address this issue. i thought gm might look further into investigation of the defective part but no. i do not want this to happen to someone else. is this a realistic expectation to have this costly repair at 47,000 miles? can we do anything else? *la | |||

| Since the accident i have complained of thumping and clanking noises.. car started to stall under 1x rpm... engine light came on, possible solution was crankshaft. then they said it was possibly a bushing. i noticed in your files someone else had the same problem. i don't understand why such problems on a car that is pampered and low miles. the dealership said it had nothing to do with the car accident???*ak | |||

| This car has been more trouble than it is worth. i have replaced the brakes and rotors twice already and need to replace them again already. i found out today that i have another craked head gasket, i replaced one two years ago just after i bought the car. the engine coolant light stays on most of the time even when the tank is full. i'm very frustrated! *ak | |||

| In less than 1 year i have taken my car to have it repaired 6 times for what i feel is the exact same problem! my engine stalls when i am coming to a stop or after being on the interstate and it idles rough. i have had my catalytic converter replaced twice in the past year, fuel sensor replaced, spark plugs, coil, wire to the ignition module replaced. my car still runs rough and stalls while driving on interstate, when idling in traffic, and when i come to a complete stop. this needs to be investigated. i have spent over $2,000 in repairs and tow fees. this is very unsafe. *tr | |||

| Engine stalls. my car will run great 2-3 days but without notice will stall while driving. i does this quite often and the mechanics cannot find problem, they cannot determine if it is spark related or fuel related due the design of the engine. i do alot of highway miles on my commute and i consider this very unsafe. (i have stalled on the highway numerous times.) | |||

| Engine shuts off without warning, while driving. fails to start when cold and also after driving. vehicle was towed twice in four days. fuel pump was initially thought to be the problem. taken to dealership 2 times in 7 days after the $700 fuel pump replacement. although technicians are doing everything they can to help me, they have been unable to identify the problem. in my opinion, the nhtsa should consider any vehicle that stops on the freeway unsafe to drive and worthy of investigation. thank you, in advance, for your assistance.. | |||

| Engine head piston bolt broke which resulted in the damage of the engine piston. all mechanics i spoke to said that it could only happen if i was going at speeds of excess of over 100 m.p.h. which i wasn't because i stopped the car quickly enough to stop further piston damage. if i didn't, the mechanics told me i might have had to buy a new engine or so they told me. people tell me that the engine piston bolt breaking is a very, very rare occurence and that it could be a manufacturer defect. please look into it so i can be absolutely sure if it was the company's fault or mine in having to pay $800.00 for something i should or should not have paid. thank you. | |||
