But when we went to pickup the gmc in springfield and return home stopping in mclean, we had another blowout this time on the rear passenger tire. We were going somewhat slower (fear slowed us to 45 or 50mph).
Anti-lock brakes failed on a wet surface causing me to skid into a van in front of me. Damage to other party was approx. &2,500. Anti-lock brakes on vehicle tend to disengage when braking on a bumpy surface which once caused me to skid into a skid.
Abs brakes failed intermittently on three different occasions, once resulting in a crash where vehicle rearended a mini van in front .
Going down steep driveway when abs brakes failed to slow vehicle. Vehicle hit tree head-on. Driver sufferend serious injuries. Engineer inspected vehicle and determined that a loss of brake fluid through a slow leak caused the brake failure. Vehicle considered a total loss. .et.
With the cruise control on I encountered sudden unintended acceleration on two occasions once while the unit was activated and once while it was not.
Dt a recall was issued on automatic transmission cooling unit and lines, but this vehicle was not included in the recall due to vin although it had the same failure as mentioned in the recall. Contacted gm, and they confirmed that recall did not include this vehicle.
Right lower ball joint failed causing front wheel to collapse car was in parking lot and moving slowly ball joints replaced by garage.
I got into the suburban to go to the store this morning, when I sat and reached to place the belt into the holder, the chair anchor snapped and I began having problems whenever stopping or accelerating.
