The transmission in my 2024 Chevrolet Blazer is very noisy often making whining and grinding sounds and I experience rough shifting and transmission hesitation during acceleration or gear changes.

My wife and I bought our '01 chevy blazer used in 04/05. From the start we had a hard time getting it to engage/disengage 4wd. This last winter my wife, the primary driver, complained that the vehicle had no power while coming home one night and the weeknights following for a week. I checked in the mornings it was fine. Pretty soon we both started noticing the gas gauge bouncing around like it was dancing. My wife thinking she was running out of gas would pull into the first gas station. She would fill up and leave the station only to have it happen again after pulling away from the pump. One month later, her and our 3 small children got stranded when they went in to convenience store. A minute later the blazer had died and the key in the on position. Replaced the fuel filter and then the fuel pump ($350 just for the pump!!!) the heating element in the pump had fried it. 04/06 the ABS failed and she almost hit a pedestrian. 2 weeks later we start hearing this popping noise when slowing/stopping and accelerating. 05/06 the battery died on her with no warning. Tried jumping it and it wouldn't hold a charge. Got that replaced. Then in 08/06 we didn't drive it because the plates had expired and we couldn't afford to replace them yet. Finally I drove it on 08/13/06 for 1 mle to the store and on my way back while stopping at the stop sign 2 blks from my house, I heard this loud clunk noise and then the vehicle started whinning. Now the thing won't move. It starts and whines, but won't move. Transmission is shot and is going to cost $1600 to replace with me doing the work. And so now, like 90% of the country, I am making a very high car payment except mine is on a car that I can not drive. This and other web sites about vehicle recalls prove that there are some serious issues with these vehicles and nothing is being done about it. What needs to happen is for some one to die b/c of these defects and then u will be scrambling to correct the problems. This is ridiculous.

Purchased vehicle 12/03 since then have replaced: water pump 3 times, radiator, thermostat, left upper ball joint, upper manifold gasket, main real seal. Over the past 6-8 months I have noticed the braking issue several times (more than 10.) luckily none were emergency stops, however when braking due to traffic light change or stopping while going downhill, the brakes "chatter," an audible whine is produced, and it is necessary to pump the brakes before it will regain pressure and stop.

Dt*: the contact stated after parking the vehicle for a few minutes, the vehicle would not restart. When the key was turned in the ignition the engine would not turn over but only made a whining noise. The vehicle was towed to an independent repair shop, upon inspection the engine had seized. The timing chain had fractured, the sparks plugs had melted and the pistons had failed. The dealer and manufacturer were alerted.

Numerous problems. All after warranty expired. Have a 2000 chevrolet s10 blazer 2 dr. It is a 4x4 with a 4.3l v6. Seat handles broke a couple of times. Terrible lifespan on those. Had replaced twice.*ak replaced defective alternator. Wasn't holding charge. Also LED to a new battery and serpentine belt. Had to replace fuses for fuel gauge. It was jumping all over the place giving incorrect readings. Had to replace numerous fuses. Terrible whining coming from the fuel pump. Chevy dealer tells me it is testing fine. But now I am having what seems like vapor lock problems on hot days. I'll go to accelerate and the vehicle will go no where and then catch and accelerate. Acts like it's going to die but hasn't yet. Diagnostics showed nothing. Terribly sporatic and makes vehicle unsafe and unreliable. It has 60,000 miles on it now. Ongoing problem to this day and I'm trying to determine if the lack of acceleration is the pump or another problem. Pedal not sticking like it was a throttle linkage. Rear windshield pump does not work. Chevy rim caps keep breaking and coming off. $30 dollars apprx. For each one and have had to replace all four at least once.

Transmission whines gears, load grinding noise. I must stop, shift into park and go but sometimes that doesn't work. Transmission shifts by itself into neutral. Problem #2 seat reclining arms on both front driver and passenger seats broke off with little pressure. Problem #3 heat only works when it wants to. Sometimes cool air comes out when heat is on. Problem #4 sometimes when applying brakes grinding noise is heard and and steering locks up. Problem #5 straps on sun visors sag considerably, blocks view.
