Chevy Blazer has low milage. However, it still has several electrical issues radio at engine start goes to loudest point and car seats move backwards at awkward times which can cause an accident. Suspension very off guard, truck drifts to the sides while driving and makes an awkward sound when turning steering wheel. The complete break / steering system is off and may cause an accident if not properly take care right away. I have no money to do this big job. Please remediate.
Not only have I had problems early with hub and bearing-- and also replaced ball bearing-- now the ABS-- manufacturers has done poor job on brake. Wheel parts- very cheap parts-- many talk about it and know that the Blazer has had problems with these parts. My family has purchased Chevy's for years-- I am now never about to purchase a Chevy again. While I pay my car payment, I always purchase new. I am always also paying for work done on this vehicle, and I am talking- over 2,000 so far and again have to go in today-- I May even trade it in I am so pissed. We also had problems with my husbands truck..I don't know what they did, or who they purchased their parts from, but surely went to cheap parts, they( Chevy) put many consumers in a bad spot. And I have written a complaint before- when I had the Chevy Blazer 2001 for a year half. …
Transmission dropped out @44000 miles. 12/02 had to replace both front ball joints. Summer of '03 started making loud popping noises which came from front right area, it would pull unexpectedly to either side - mainly to the right and service 4wd light would come on. 10/03 had to have right front wheel bearing replaced. Could find nothing wrong with 4wd-don't know why light keeps coming on. Now 01/04, right front wheel bearing needs replaced again. I'm told part under warranty as long as I own vehicle cause GM has received so many complaints. What is GM doing to correct the root cause of this? I see I am not the only one with this problem. Thank god I have not had any accidents, but have had a few near misses because the it would "jerk instantly" and it caught me off guard. Does an accident / injury / fatality have to happen before corrective action is taken?
1) ABS and e-brake light continually come on; unsure if ABS system is functional; I have had the computer tested and it returned no faults 2) side windows work intermittently; no explanation; windows will not roll down for days at a time and then they work fine for days at a time 3) sunroof no longer functional; Chevy dealer said the "heat" warped the internal parts and they broke as I rolled it back; weather was mild and the breakage happened at 0500 in the am; I don't believe it was heat related 4) rear of vehicle is has drastically fallen below the front; I have no explanation as to why; it looks as if the vehicle front suspension was raised and the rear was lowered; drives fine, but feels unsafe all of the above happened shortly after the warranty expired, between 40000-50000 miles.
Consumer heard a noise in the front of vehicle. Consumer stated he had been hearing it a little, but currently the noise became more pronounced. Consumer had already replaced the transmission once. The consumer had to fill the tires every week. The tires leaked air since purchase. The tire service dealer suggested that there was no leak and that corrosion built up on the wheels in which air escaped through the rim of tires. There was a thumping noise in the front end and seems like it happens worst on right turns, the left wheel bearing was loose in the hub bearing assembly, the hood hinges rattling excessive clearence, there was excessive slippage and the clutch burnt.

I have reviewed other owners complaints regarding their front suspension, fuel pump with random shut offs. My vehicle is experiencing the same and similar problems. As of today my vehicle is in the shop;I was doing 35-40 MPH when vehicle just un expectedly shut off. I was stranded on a major road which cause a significant traffic delay. I have an oil leak from the hose leading to my oil filter and the vehicle pull to the right sharply if I release the steering wheel. The vehicle makes a popping sound when turning. These problems are hard to find just an isolated incident when so many consumers are having the same problems.
My 2001 Chevy Blazer had uneven tire wear indicating the need for a front end alignment. During the inspection I was informed that the lower ball joints had to be replaced as well as the idler arm and should do the upper joints as well. I had never heard of a vehicle with 56,000 miles needing to have this done. Of course, now I hear of many owners having the same problem. The unexpected $900 bill was not pleasant! The mechanic said it was a common problem that he saw with Chevy products. Do I have any chance of being compensated for the less than quality parts installed on my vehicle?
I own a 2001 Chevrolet 2dr 2wheel drive Blazer. The wheel bearings and spindle / parts have already needed to be replaced on both sides/front. I found this problem because the wheel of my front passenger side came off while I was driving. Thankfully I heard the grinding and slowed my speed to 5-6 MPH and had turned my hazard lights on. From what I am learning this is a problem that is some what common with my make/model vehicle. I have also seem complaints of this nature on canadian auto club sites.
Had a terribly loud noise in the front end of our 2001 Chevy Blazer and found out it was a front wheel hub and bearing assembly, cost $439.81. Now one year later the other side has gone and had to be replaced, we have almost $900. Into this repair that I now see appears to be a frequent problem with this vehicle. General motors needs to be accountable for there products, either on there own or forced to do some type of recall. We also had to have the brake light recall taken care of
Vehicle was stalling without warning and could not be restarted until a minimum of 30minutes had elapsed. Vehicle checked by dealer who determined original delco battery leaked through the battery tray and damaged the function of the vehicle's computer. Ts consumer stated the engine stills shuts off at times. The throw-out bearings were noisy. The dash lights become very hot after vehicle has warmed up. Door on fuel tank rattles when moving.
