A wire inside the head light switch can fatigue and break over time causing the head lights to be inoperative. There is an updated head light switch to fix the problem.
The Check Engine Light may illuminate with a stored code P2006. This is most often caused by a sticking intake manifold runner control (IMRC) valve. Our technicians tell us that depending on your vehicle the valve may require replacement and/or the powertrain control module (PCM) software will require upgrading.
Everyone and their mother has a transfer case leak on their speed6.
They must have made this system out of the cheapest aluminum that they could find.
My leak has now turned into a stream and powertrain warranty is up by a year.
my car now has 51k miles and they whole transfer case needs to be replaced. well over $3 grand.
The intake manifold gasket can fail causing vacuum a leak and/or a rough idle condition. Replacement of the leaking gasket will be necessary to correct this concern.
Excessive engine vibration or knocking noises heard while the engine is idling, being started or switched off are usually caused by a defective engine mount at the top right side of the engine. A redesigned engine mount is available to alleviate this problem.
The DPFE (differential pressure feedback EGR) sensor tends to fail. The DPFE sensor monitors function of the EGR valve by measuring pressure changes in the exhaust gas recirculation (EGR) system. Symptoms of a failing DPFE sensor are hesitation or stumbling when driving along with illumination of the Check Engine Light.
If the engine is misfiring, it may be caused by a damaged wire(s) which connect the fuel injectors to the Powertrain Control Module (PCM). The damaged wire(s) can be repaired or the emission wire harness replaced. A misfire can result in a loss of engine performance and illumination of the Check Engine Light.
Some models may have a problem with stalling under light acceleration. Updated software for the powertrain control module (PCM) is available which may help with this concern.
If the engine surges and hesitates, our technicians recommend checking the condition of the ground on top of the engine block, under the intake. Restore the grounding point if it is found to be corroded or compromised.
The mass airflow sensor may fail causing a stalling and/or lack of power. A faulty mass airflow sensor should be replaced to correct this concern.
rear heating line rusty and suddenly start pouring coolant out ,if u see rust dont take it long trip!!! you will get stuck!
rear heating line got very rusy and leaked. its so expensive to buy the parts almost $1200. So i made copper tubing from homedepot and made my own coolant line. working good.
