Last fall 10/14 replaced all brake lines due to corrosion (97000 miles). Which has been mentioned numerous times already. After that ABS light came on intermittently lost brakes last week to it to the shop they had it for the day everything worked fine. Continued driving light started coming back on & brakes were erratic. Yesterday was pulling out of parking lot had no brakes. If these are known problems why isn't anyone taking care of it. Why you would put untreated brake lines on a vehicle in the salt districts is beyond me. I had an 1989 Oldsmobile with the original line on it til 198,000 miles. I also replaced the transmission at 77,000 miles due to corrosion of the lines.($2700)
While merging onto the express way I had a major loss of power and a slight shake in my Silverado. Multiple engine lights came on (stability track, traction control, and blinking engine light). On my way to the nearest GM dealer, at every stop light the truck lacked power to get going when the peddle was pushed, then it would kick in and screech the tires. After leaving the truck at the dealer, I receive phone call from the dealer the following day stating that the lifter (afm lifter) had malfunctioned and was stuck. I asked what causes this (because my truck only has about 39,700 miles on it), and the dealer stated it was "an issue with the design of the engine." I then researched the internet (GM forums, social media, NHTSA) to find out that this is a huge issue. Many owners had the bad lifter replaced under warranty, only to have a different lifter go bad. …
Tl contact owns a 2007 Chevrolet Silverado lt. The contact stated the throttle would stick anytime he attempted to release the pedal. The vehicle slows down very slowly. The engine continues to run at 800-100 RPM's until the brake is applied to stop the vehicle. The consumer also stated while stopped at a traffic light or a stop sign, the engine would occasionally speed up to approximately 1800 RPM's. The consumer also stated a new engine was installed on April 11, 2001 due to a faulty oil pump. The throttle body and engine control module were replaced twice, the hbac control module, oil deflector, purge valve and canister, maf sensor, wiring harness, speed sensor, co2 sensor, 175 amp fuse box, transmission control module and under hood wiring were all replaced. …
Thump after coming to a stop. After about 24,000 miles. I started feeling a light thump from the rear, as if someone bumped me from behind. Over the next few weeks it became very noticeable, so I took it to the dealer for investigation. The 1st time, they said the rear-end had the wrong lube in it & they replaced it. This seem to work for the next several weeks. Then the thump returned lightly at 1st & gradually worsened to a major thump. I returned it to the dealer & this second repair was that the lubed the rear-end & replaced the yoke on the driveshaft. This repair worked for about a week & I started feeling the light thump again. I took it back in again, left it all day & they apparently drove it around the parking lot & couldn't duplicate the problem. One of the service managers rode with me, around the parking lot & the problem wouldn't show up. …
Vehicle is parked in garage overnight,get in to start ,shift lever in park,turn on key,vehicle's transmission sends out a "clunk", as if to engage and go forward or backward. This type of action started around 8000 miles as a slight, "clunk" extending into 49000 miles with a hard jarring"clunk". Of course I took it to dealer in the course of the warranty ,had them note and record defect,however dealer could not get vehicle to perform this operation while in their possession which extended over night and sometimes 2 nights. While the vehicle does not do this on a regular basis,it is notably getting a harder sounding, more pronounced "clunk". The shifting noise of the transmission is becoming evident, that is in low speed there is more rough clunking as the transmission goes through it's gears.
GM has a design and/or manufacturing flaw in the transmission lines on the 2500hd. I have had mine replaced under warranty once, and need to have them replaced again. They only leak in cold weather when the rubber in the line shrinks at the crimp causing them to leak. The danger here is the fire potential. Due to the diesel regeneration process that burns off the diesel particulate filter and the heats it to extreme temperatures this has a potential fire risk. GM refuses to address the leaky transmission lines. There are multiple accounts of this issue, on several year models of durmax pickups, on the internet. Additional concerns here are how acidic transmission oil is. It also has potential to deteriorate rubber steering components boots ball joint covers, etc. This is safety concern.
On 10/18/2010 returning home from vacation, my right front wheel assembly suffered severe internal failure. The dealer in south carolina repaired my vehicle, and covered the expense of the replacement part and labor under the powertrain warranty. They also had to replace the front brake pads and resurfaced the rotors which were damaged to the severe internal failure of the wheel hub assembly. I can understand the malfunction of the part, it happens. But, on 12/17/2010 the left front wheel assembly suffered internal failure, again the dealer covered the expense of the replacement part and labor under the powertrain warranty. I believe their must be a problem for both front wheel hub assemblies to fail, I only have under 30,000 miles on the vehicle. Thank you.
I am getting a noticeable vibration in the drive train at about 45 MPH. It finally subsides at around 55 MPH. I have had the oil level checked in the transmission and the rear end oil checked. All is OK in those areas. Contacted a local Chevrolet dealer and explained the situation on the phone and I was told that is was normal for that make, model and drive train. Also had the underside of the vehicle checked to see if there was anything loose that might cause the problem especially the exhaust system and all is OK. Never had this problem before. Just started. Chevrolet won't bother with it.
Hesitation on acceleration. While merging onto an interstate highway pressed the accelerator to rapidly increase speed but the vehicle hesitated causing me to have to continue down the shoulder and actually stop to avoid a stalled vehicle on the shoulder. I have taken my vehicle to two different dealers to investigate the hesitation on acceleration both have stated that this is normal operation for the 2007 Chevrolet Silverado. Although I didn't have an accident with this particular incident I have noticed this hesitation during normal day to day driving. This is a safety issue.
Tl contact owns a 2007 Chevrolet Silverado. The contact heard a noise coming from the automatic transmission and the vehicle was hesitant to shift into gear. The dealer repaired the vehicle under warranty. The failure recurred and the vehicle was taken back to the dealer. They stated that there was an issue with the vehicle and notified the manufacturer. The manufacturer advised the dealer not to make any further repairs until the transmission actually failed. The dealer obeyed the manufacturer. The VIN was unknown. The failure and current mileages were less than 20,000.
