Truck was purchased 7/7/20. Seemed to work fine, but started noticing engine trouble on 9/10/20. Had only driven it ~150 miles since purchase, never any strenuous driving. Took it in to get serviced on 9/21/20, where several problems were spotted, one of which is traceable to the dealer: 1) the distributor cap was being held on only by two zipties. This is why it seemed to run fine on the date of purchase, but caused engine misfires within a few months of light use. The dealership notified me the day before I purchased it that the distributor was being fixed, but they failed to notify me that it wasn't fixed properly. Truck now misfires, has an arcing wire, and is unsafe to drive. 2)truck was sold with no parking brake, and no warning that it was not installed. This information has omitted when I asked about safety issues before purchasing. Never noticed because phx is so flat. Had I needed to use the parking brake, not having one installed is a significant safety issue. 3) an impact sensor was left hanging from the rear of the vehicle. A large enough bump or a rock could set off airbags while driving, putting my passengers, myself, and other drivers and pedestrians at serious risk. This truck is very unsafe to drive, and I was not responsible for any of the issues that made it unsafe. The first issue was caused by a bad repair made by the dealership, and the other two noted issues were not noted in the carfax or by the salesperson when I asked about safety issues.

I had a p0300 code which is a random misfire code after replacing all the parts that I was told that give this code I still had the problem. After doing some in depth research I found that gm had purchased defective distributor drive gears that were not hardened properly causing them to wear out. The knock sensor would pick up this wear and the computer would retard the timing and cause crossfire or a spark jump that caused the distributor cap to prematurely burn out. Gm new about this problem and never did a recall on this. I spent a lot of money on parts I didn't need if I would have known what the root cause of the problem was this. Information needs to get out to thousands of people that are chasing this p0300 code on gm vehicles. My vehicle is a 97 s10 4.3 vortec. When the computer kicks this code out the engine skips off idle and the vehicle shakes and stumbles. After replacing the distributor that had a new drive gear the vehicle runs like new again and no codes are set.

When I test drove this vehicle, I "punched" the throttle to check response, engine-misfire, smoke, etc. The throttle stuck in the open position and the vehicle continued to accelerate. Repeated punching of the accelerator released the throttle and I was able to reduce engine speed. The dealer indicated that this problem was caused by carpeting snagging the throttle cable. (wrong). The dealer examined the vehicle, declared the problem cured, and I purchased the vehicle. Since that time, the throttle has stuck more than a dozen times. This is particularly dangerous when attempting to pass another vehicle, or accelerating from a traffic light. The throttle stuck once when I was pulling into a downtown parking lot. In all these cases, had I not known what to expect, there could have been an accident. No parts have ever been replaced on this vehicle to the best of my knowledge. The first incident occurred on august 21, 2004 and another incident occurred today (february 25, 2005).

Automatic transmission cooler broke while driving and contaminated other components within the engine compartment. This made driving and gear changing difficult. Dealership will replace all contaminated components. *ak the "service engine soon" light illuminated so the consumer took the vehicle to the dealer. The consumer had the radiator flushed at 550 miles and the engine continued to run rough. On one occasion, the consumer started the engine and it lunged forward almost knocking him to the driveway. The service manager agreed that the radiator may be defective. *ph the battery was replaced, the instrument panel cluster was replaced because it had shorted out.

Car is dangerous in that it misfires in higher speed conditions. Chevy executive office and 2 dealers (o'connor & bob johnson in ny) refused warranty coverage after their 4th attempt failed to cure the problem. 2 independent shops verified problem.
