Owner reports
Selected complaints filed with NHTSA by 1999 Chevrolet S10 owners, lightly cleaned up (personal details are redacted by NHTSA).
The recline handles on both of my seats snapped off the first time they were used. I took it ti the dealer and they said it was not covered by the warranty. I was told that I would have to replace the seats inorder to fix the problem... They also told me that I broke them by applying to much force to the seat recline levers. I am only 5,2 and I dont think I could apply that much force to break metal unless they were defective to begine with. I would accept it if only one broke but when both of them broke this is a little more than coincidence... I would like cheverolet to recall these or issue a repair part.
Driver and passenger seat recliner handle broke off very easily. We are now unable to recline both seats in my truck. When I went to the dealership they said "that this was a common problem with Chevy s-10" (per the parts counter & service department). I was advised that I would need to replace the entire recliner assembly and the handle, they wanted $600 to fix this! I could buy a lazy boy recliner for that kind of money. This is totally ridiculous and they need to fix this. The parts dept. Guy told me that they redesigned this recliner because they were having so problems with the old one.
Lever to recline and raise the seat has broken, not the plastic handle, but the metal that connects the lever to the seat. The metal is very coarse & brittle and doesn't seem suited to it's intended use. Fortunately, my seat is stuck in an upright position. Unfortunately, the break occurred post warranty. Bottom line, the levers on the seats of Chevrolet s-10's are junk, not intended to last, and could result in injury if locked in an unsafe position when the break occurs.
While reclining the driver side seat, the lever broke without any force being applied. Also, the passenger side lever broke on a separate occasion. No force was used in either incidents they simply broke during normal use. The cost to repair the vehicle was approximately $186.00 each. GM refuses to repair the seats and they have not issued a recall knowing there is a definitely a problem with the seats. Also the door handle on the jump door extended cab broke.
Seat recliner adjuster handles attach to a ferrelled piece of pot metal that is drilled and slotted to accept a screw that holds the handle. This piece of weak metal breaks easily and the handle falls off rendering the back of the seat non adjustable. Several dealers tell me they have replaced hundreds of these at a total cost of $125 (labor and parts). GM tells customers this is normal wear and can be expected.
Defective parts ---right and left seat back recliners broke in the same identical places after very little use. The right side broke with no more than 4-5 times of use. The left side broke after no more than 10 times of use. If this was a item that got used every day I would understand they might wear out. I had the extended warranty but it expires at 75000 miles so GM refuses to warranty it.
Dt: the caller said a truck he use to own had a problem with the passenger seat sliding forward. The caller took vehicle to the dealer twice for this problem. Dealer said they fixed it, but the caller stated it was not fixed. Dealer has not been contacted lately. Manufacturer has not been contacted yet. The caller gave vehicle to his son, who has not taken vehicle to dealer .
Seat recliner lever breaks and falls off. This applies to all 1999 Chevrolet S10 pickup and S10 blazers. Both driver and passenger seats. Witnessed this occurrence on 4 different S10 pickup/blazers. Metal is made of cheap cast that breaks off even with no use. Levers fall off during vacuuming/opening door and regular use. No available replacement part or remedy to my knowledge.
No events leading to it. Just happens out of the blue when using it. This happens sporadically. Seat recliner levers defective and break very easy, the parts that hold it together are cheap die cast metal. Haven't bothered replacing as I cannot afford, dealer wont replace, junk yards don't have them.
Service engine light came on shortly after purchasing truck,it took several times before the problem was corrected,then when vehicle got to 50010 light came back on. Took back to dealer they fixed it again. Now it comes on for a few days then goes back off.,then back on again. Seat recliner handle broke off while truck was parked, as with the 3rd door handle also. Right front wheel hub bearings went out driving down the road. Seems that either of the components mentioned should have never happened with the mileage and I believe that it is caused by a poorly built vehicle by general motors.most of the problems began after the warranty ran out, with the exception of the service engine soon light which is an ongoing problem.
