2007 Chevrolet Colorado Electrical System

MY 2007 CHEVROLET COLORADO LS 4 CYLINDER 2.9 LITRE HAS ALWAYS RANDOMLY WON'T START. I RESEARCHED THIS AND EVERY YEAR OF THE COLORADO HAS HAD THIS ISSUE OF RANDOMLY NOT STARTING, COUNTLESS DOLLARS HAVE BEEN SPENT TRYING TO FIGURE IT OUT, CHEVROLET WILL NOT SAY IT IS AN ISSUE AND IT IS A HUGE ISSUE FOR ALMOST EVERY SINGLE YEAR. PASSLOCK ISSUE? JUST COSTED ME 266.00 AT THE CHEV GARAGE AND MY TRUCK STILL IS STRUGGLING TO START, BEEN TOLD STARTER AND BATTERY ARE FINE. ALTERNATOR VOLTAGE REGULATOR ARE FINE. LEMON PLEASE RECALL FOR THIS ISSUE IT'S SO UNFAIR TO US CONSUMERS TO WASTE MONEY TRYING TO FIGURE OUT A FAULTY DESIGN IN A VEHICLE. GO ON YOU TUBE, COUNTLESS PEOPLE SHARE THE SAME ISSUE. COULD GET ME FIRED FROM MY JOB FOR MY TRUCK NOT STARTING CONSTANTLY. IT WILL START COUNTLESS TIMES THEN NOT START USUALLY WHEN YOU NEED IT THE MOST. ESTERO BAY CHEVROLET HAS MY RECORDS.

ENGINE WILL NOT START TURNS OVER LET SIT FOR 10 MINUTES TO 2 HOURS WILL START HAD CHECKED ON COMPUTER SEVERAL TIMES NOTHING SHOWS UP WAS TOLD IT WAS CRANK SENSOR REPLACED WITH NO CHANGE NOW IM TOLD IT IS SECURITY SENSOR TRUCK HAS DONE THIS SINCE IT WAS NEW RANDOMLY NOW HAS 78K MILES GETTING SICK OF BEING STRANDED AND LATE TO WORK GM SHOULD HAVE A RECALL ON THIS

"TAKATA RECALL" THE CHECK ENGINE LIGHT COMES ON THEN THE SECURITY LIGHT COMES ON THEN IT GOES CZASY.ALL THE LIGHT START FLASING BUT IT WANT START.HAD IT TOWED TO FIRESTONE THEY SAID BATTERY AND CABLE NEED CHANGING ;DID THAT THEN THEY SAID THE TRUCK SAT IN BAY AND STARTED UP BY ITSELF. THE PAASLOCK WILL NOT LET ME DRIVE THIS TRUCK

TL* THE CONTACT OWNS A 2007 CHEVROLET COLORADO. THE CONTACT STATED THAT IT TOOK SEVERAL ATTEMPTS TO START THE VEHICLE. THE FAILURE OCCURRED NUMEROUS TIMES WITHOUT WARNING. THE VEHICLE WAS TAKEN TO YOUNG CHEVROLET (9301 E R L THORNTON FWY, DALLAS, TX 75228, (469) 294-3000), BUT WAS NOT DIAGNOSED OR REPAIRED DUE TO THE COST. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DID NOT ASSIST. THE APPROXIMATE FAILURE MILEAGE WAS 77,000.

PASSLOCK SECURITY SYSTEM MALFUNCTIONS AND RANDOMLY DOES NOT LET YOU START YOUR VEHICLE FOR TEN MINUTES LEAVING YOU STRANDED. SOMETIMES IT WILL DO IT CONTINUALLY. HAVE HAD TO WAIT AS LONG AS 80 MINUTES TO START.

ON MAY 6, 2017, OUR 2007 CHEVROLET COLORADO WAS DRIVEN APPROXIMATELY 400 MILES WITH SEVERAL STOPS AND TURNED OFF WITH NO PROBLEMS. ONCE WE ARRIVED AT DESTINATION, SAID VEHICLE WAS PARKED IN DRIVEWAY OF RELATIVE'S HOME. LAPSE TIME OF ABOUT AN HOUR, THEN THE TRUCK WOULD NOT START. NOTHING ELECTRICAL WORKED. AFTER LEAVING THE TRUCK OVERNIGHT, THE NEXT MORNING THE TRUCK STARTED UP AND RAN AS IF NOTHING EVER HAPPENED. WE RETURNED THE 400 MILES HOME WITHOUT INCIDENT. A MONTH LATER, (6/12/17) THE TRUCK WAS DRIVEN ABOUT 5 MILES, PARKED, TURNED OFF AT A GROCERY STORE. APPROXIMATELY 30 MINUTES OF SHOPPING, RETURNED TO TRUCK AND IT WOULD NOT START. HAD TO LEAVE IT THERE AND HOPEFULLY IT WILL START IN THE MORNING. I AM DEEPLY CONCERNED ABOUT COMPLAINTS I HAVE ENCOUNTERED ON SEVERAL WEBSITES ABOUT THESE VEHICLES. IT APPEARS THAT THIS IN NOT AN UNCOMMON PROBLEM WITH THE CHEVROLET COLORADO. IT ALSO APPEARS AS IF NO PROBLEM HAS BEEN ACKNOWLEDGED BY CHEVROLET NOR A RECALL HAS BEEN ISSUED. AFTER MUCH RESEARCH I CAN FIND NO DEFINITIVE SOLUTION TO THE PROBLEM. SURELY CHEVROLET COULD AT LEAST GIVE US A FIX FOR THIS PROBLEM AS IT HAS CAUSED ALL KINDS OF INCONVENIENT SITUATIONS AND LIFE THREATENING INCIDENTS WHEN THE TRUCK DECIDES TO QUIT RUNNING AT INTERSTATE SPEEDS.

TL* THE CONTACT OWNS A 2007 CHEVROLET COLORADO. THE CONTACT STATED THAT WHEN THE ANTI-THEFT MODE ILLUMINATED, THE VEHICLE FAILED TO START. THE FAILURE RECURRED FIVE TIMES. THE VEHICLE WAS TAKEN TO JEFF GORDON CHEVROLET (228 S COLLEGE RD, WILMINGTON, NC 28403) WHERE IT WAS DIAGNOSED THAT THE IGNITION SWITCH MECHANISM FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO THE REPAIR FEES. THE MANUFACTURER WAS CONTACTED AND INFORMED THE CONTACT THAT THEY WOULD NOT REPAIR THE VEHICLE AND THAT HE NEEDED TO PAY THE FEE FOR THE REPAIR. THE APPROXIMATE FAILURE MILEAGE WAS 40,000. UPDATED 10/25/17*LJ *TT

TL* THE CONTACT OWNS A 2007 CHEVROLET COLORADO. WHILE DRIVING AT AN UNKNOWN SPEED, AN ELECTRICAL BURNING ODOR WAS PRESENT INSIDE THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DISCOVERED THAT EXCESSIVE VOLTAGE WAS PRESENT IN THE BLOWER MOTOR FAN AND DRAWING TOO MUCH CURRENT, WHICH CAUSED THE ELECTRICAL WIRES TO OVERHEAT, BURN, AND MELT. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VIN WAS INVALID. THE FAILURE MILEAGE WAS 28,000. *JS

ANTI-THEFT LOCKS UP ENGINE SOMETIMES TWICE A DAY. MUST WAIT 15 MINUTES FOR ANTI-THEFT TO TIMEOUT FOR VEHICLE TO START. I'VE HAD NUMEROUS VISITS TO MECHANICS, LOCKSMITHS, TRUCK TOWED. GM DEALER TELLS ME THEY HAVE NEVER HEARD OF THIS PROBLEM. I SEE THIS IS A VERY COMMON PROBLEM AMONG OTHER 2007 CHEVY COLORADO OWNERS. I HAVE EMAILED GM WITH A COMPLAINT AND THEY NEVER RESPONDED. VERY FRUSTRATED! I HAVE BEEN A LOYAL CHEVY OWNER MY WHOLE LIFE. I WILL NEVER BUY ANOTHER CHEVY AGAIN. UNFORTUNATELY I'M NOT WEALTHY AND CAN'T JUST REPLACE THIS DISASTER OF A VEHICLE. LET'S HOPE I'M NEVER IN AN EMERGENCY SITUATION WHERE MY VEHICLE NOT STARTING CAUSES DETRIMENTAL RESULTS. SHAME SHAME SHAME ON YOU CHEVY FOR YOUR UTTER LACK OF RESPONSIBILITY TO FIX A KNOWN PROBLEM. *TR

TRUCK WAS STATIONARY, TRIED TO START, TURNED OVER BUT DIDN'T START. WAITED 10-15 MINUTES AND STARTED OK. THIS HAPPENS ONCE A WEEK AND HAS SOMETHING TO DO WITH 'PASSLOCK'. ONCE I WAS ON WAY TO HOSPITAL, DELAYED AGAIN. DEALER HAS MULTIPLE GUESSES BUT NO FIXES.

THIS IS A SAFETY ISSUE AS THE VEHICLE (MANY 2007 COLORADO'S AT LEAST FROM REVIEW OF THE NHTSA COMPLAINT PAGE & DISCUSSION WITH OTHER USERS) FAILS TO START, SOMETIMES ONCE, SOMETIMES TWICE, AND I HAVE HAD 4 OCCASIONS IN A ROW WHERE THE TRUCK FAILED TO START. IT APPEARS THE ANTI-THEFT SYSTEM ENGAGES FOR NO APPARENT REASON RESULTING IN A 10-15 MINUTE "TIME OUT" BEFORE YOU CAN AGAIN ATTEMPT TO START THE VEHICLE. OBVIOUS AS THE ANTI-THEFT ICON IS FLASHING WHEN YOU ATTEMPT TO RESTART THE VEHICLE. THIS AT FIRST WAS SIMPLY AN INCONVENIENCE, BUT NOW IT IS NOT ONLY FRUSTRATING, IT IS DANGEROUS SHOULD YOU HAVE TO NEED THIS VEHICLE IN A EMERGENCY (EVACUATION FROM YOUR HOME OR A MEDICAL EMERGENCY). THIS HAD FIRST STARTED TO BE ONCE EVERY FEW WEEKS, AND NOW THAT I'M AT 61,500 MILES, IT HAS BEEN MORE FREQUENT (ONCE IT HAPPENED 4 TIMES IN A ROW) ALMOST 3-4 TIMES PER WEEK. YOU CAN'T BE EXPECTED TO CHANGE YOUR SCHEDULE TO GO TO WORK OR JUST USE THE VEHICLE TO CARRY ON YOUR LIFE 30-40 MINUTES EARLIER THAN YOU ALREADY DO JUST IN CASE THE VEHICLE FAILS TO START; OR BE ABLE TO USE THIS VEHICLE WITH ANY RELIABILITY IN AN EMERGENCY. SPOKE WITH A LOCAL CHEVY DEALER REPAIR SHOP ON THE PHONE MONTHS AGO AND THEY BASICALLY SAID THEY WERE NOT AWARE OF THIS TYPE OF ISSUE AND MOST LIKELY COULDN'T RESOLVE IT AS IT IS AN INTERMITTENT PROBLEM.

TL* THE CONTACT OWNS A 2007 CHEVROLET COLORADO. THE CONTACT STATED THAT THE PASS LOCK ANTI THEFT SYSTEM MALFUNCTIONED AND THE VEHICLE COULD NOT BE STARTED. THE IGNITION KEY WAS REPLACED BUT THE FAILURE CONTINUED TO OCCUR. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 60,000.

AIR CONDITIONING FAN MOTOR STOPPED WORKING ON POSITIONS 1,2 AND 3 AND WORKS ONLY ON 4. NEW BLOWER MOTOR RESISTOR REQUIRED.

IT WAS FIX BY GM FOR $385.00 IGNITION SWITCH *TR

VEHICLE FAILED TO START AFTER BEING DRIVEN, THIS HAPPENED TWICE PREVIOUSLY, ONCE AT APPROXIMATELY 59K AND AGAIN AT APPROXIMATELY 60K MILES. IT APPEARS THIS IS THE SAME PROBLEM OTHER 2007 COLORADO OWNERS HAVE IDENTIFIED. VEHICLE CRANKS, BUT DOES NOT FIRE AS THERE APPEARS TO BE NO FUEL FLOW. AGAIN AFTER WAITING 10-15 MINUTES IT WILL START. THIS IS NOT A SAFE SITUATION FOR ANY VEHICLE OWNER, IF THERE SHOULD BE AN EMERGENCY THAT THE OWNER NEEDS TO GET AWAY FROM, WAITING TO GET YOUR VEHICLE STARTED IS NOT AN ACCEPTABLE ACTIVITY FOR ANYBODY. I AM A SAFETY OFFICER WITH A STATE DOT AGENCY AND MUST BE ABLE TO RESPOND AFTER HOURS FOR EMERGENCY EVENTS, SHOULD MY VEHICLE NOT START, WAITING IS NOT AN ACCEPTABLE ANSWER FOR MY DELAY. *TR

TL* THE CONTACT OWNS A 2007 CHEVROLET COLORADO. THE CONTACT STATED THAT THE VEHICLE FAILED TO START AND THE ABS WARNING INDICATOR ILLUMINATED INTERMITTENTLY. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 54,000.

ONCE EVERY MONTH OR SO THE TRUCK WILL NOT START. MAKES NO DIFFERENCE IF THE TRUCK HAS BEEN IN THE GARAGE ALL NIGHT OR SHUT OFF FOR 10 MINUTES. THE LOCK INDICATOR LIGHT ON THE DASH FLASHES. AFTER WAITING FOR 15 MIN. THE TRUCK WILL START. I AM USING THE SAME KEY HAD TWO DEALER (OLD GLENWAY CHEV.) AND ANDY'S CHEV. SEVERAL TIMES HOWEVER THEY COULD FIND NO PROBLEM. *TR

THE VEHICLE WON'T START, THEN WILL START LIKE TEN TO TWENTY MINUTES LATER. FIRST IT TURNS OVER AND MAKES THE SOUND LIKE YOU STARTED IT WHILE IT WAS RUNNING THEN IT TRIES TO START ON ITS OWN, BUT CAN'T! IT TURNS OVER FINE LIKE IT WILL START AFTER THAT BUT CAN'T START. BATTERY SEEMS TO BE FINE, JUST WON'T IGNITE THE ENGINE. THIS HAPPENED TWO DAYS IN A ROW. I CAN'T PLAN AROUND THIS. MY KIDS ARE GETTING TO SCHOOL LATE! I DON'T WANT TO GET STUCK SOMEWHERE I'M NOT SAFE EITHER! *TR

OFTEN MY TRUCK WILL NOT START UP, I HAVE HAD IT CHECKED AND I AM TOLD THE BATTERY AND CABLES ARE FINE.. SO I AM GUESSING IT COULD BE THE STARTER (IGNITION) SWITCH.. IS MY TYPE OF TRUCK ON THE RECALL LIST? THIS HAPPENS QUITE OFTEN AND IT HAPPENS AT A VERY INCONVENIENT TIME. MAYBE YOU CAN TELL ME WHAT IS WRONG AND WHAT TO DO TO GET IT FIXED. *TR

TL- THE CONTACT OWNS A 2007 CHEVROLET COLORADO. THE CONTACT STATED THAT THE IGNITION FAILED AND HE WAS UNABLE TO START THE VEHICLE. THE VEHICLE ALSO STALLED INTERMITTENTLY WHILE DRIVING DUE TO THE IGNITION SWITCH FAILURE. THE VEHICLE WAS TAKEN TO THE DEALER REPLACED THE IGNITION SWITCH. THE VEHICLE WAS REPAIRED.

VEHICLE WOULD NOT START AFTER PARKED AND SHUT OFF ENGINE. FOUND THAT THE PASSLOCK ANTI-THEFT SYSTEM HAD ACTIVATED SOMEHOW. THE ENGINE WOULD NOT TURN OVER, ONLY A FEW AUDIBLE TONES AND THE RED "LOCK" LIGHT ON. ALSO IT SHOWED AN ABS FAULT. NOTE- I DO NOT HAVE AN AFTERMARKET ALARM OR LOCKS ON MY TRUCK, I ACTUALLY DON'T HAVE ANY AFTERMARKET ANYTHING ON MY TRUCK BESIDES TINTED WINDOWS. I CHECKED THE BATTERY WITH MY MULTIMETER, VOLTAGE WAS AT 12.7VDC. AFTER A FEW MORE UNSUCCESSFUL ATTEMPTS, I UNHOOKED THE BATTERY AND LET IT SIT FOR ABOUT 15 MINUTES TO MAYBE RESET THE COMPUTER. TRIED AGAIN AND FOUND THAT THE COMPUTER DID NOT RESET. CALLED THE DEALER, JN AUTOMOTIVE IN HONOLULU, AND THEY SAID THEY HAVE NEVER HEARD OF THE PROBLEM AND TO BRING IT IN. I GOT IT TOWED THERE AND AFTER A DAY THEY SAID THAT THE BATTERY HAD A LOW VOLTAGE OF 11.6~VDC AND THAT'S WHY IT WOULDN'T START/TURN OVER. I KNOW FOR A FACT THAT 11+VDC WILL TURN AN ENGINE OVER AT LEAST A FEW TIMES IF NOT JUST START IT. SO THEY WERE ABLE TO START THE TRUCK BY APPARENTLY UNHOOKING THE BATTERY FROM THE TRUCK FOR A LONG PERIOD OF TIME (MAYBE AN HOUR, OVERNIGHT, WHATEVER) AND REPLACING IT. THIS DID NOT SOLVE THE ISSUE OF WHY MY TRUCK "ALL OF A SUDDEN" INITIATED THE ANTI-THEFT SYSTEM AND LOCK ME OUT FROM STARTING THE ENGINE. THEY CHARGED ME OVER $200 FOR A NEW BATTERY PLUS $100+ FOR LABOR BECAUSE THEY SAID THE PROBLEM WAS WITH THE BATTERY AND NOT THE TRUCK ELECTRONICS. I REALLY NEEDED MY TRUCK AS I HAD ALL MY TOOLS AND PAPERWORK IN THERE AND I HAD TO GO BACK TO WORK. THEY SAID THIS IS THE FIRST TIME THEY ENCOUNTERED THIS PROBLEM. GOOGLE REVEALED MANY ACCOUNTS OF THIS PROBLEM. OH, AND BY THE WAY, WHEN I WAS THERE I SAW AT LEAST 6 NEWER CORVETTES AND 4 NEWER AVALANCHES THERE FOR SOME PROBLEM SO WATCH OUT CHEVY OWNERS... *TR

2007 CHEVROLET COLORADO. CONSUMER STATES MALFUNCTION WITH THE PASSLOCK SYSTEM *TGW ACCORDING TO THE OWNERS MANUAL, THE PASSLOCK IS A THEFT-DETERRENT SYSTEM. THE PASSLOCK ENABLES FUEL OF THE IGNITION LOCK CYLINDER IF TURNED WITH A VALID KEY. IF AN INCORRECT KEY IS USED OR THE IGNITION LOCK CYLINDER IS TAMPERED WITH, THE FUEL SYSTEM IS DISABLED AND THE VEHICLE WILL NOT START. WHAT WAS NOT MENTIONED IN THE OWNER'S MANUAL IS THAT THE SYSTEM MALFUNCTIONS EVEN WHEN A VALID KEY IS USED AND OR THE LOCK CYLINDER HAS NOT BEEN TAMPERED WITH. THE SYSTEM FAILED ON NUMEROUS OCCASIONS. EACH TIME, THE CONSUMER HAD TO WAIT 10-15 MINUTES AND THEN THE ENGINE WOULD START. THE VEHICLE FINALLY FAILED ALTOGETHER AND HAD TO BE SERVICED AT THE DEALER. AFTER THE VEHICLE WAS SERVICED, FIVE MONTHS LATER, THE VEHICLE FAILED TO START AT A REST STOP. THE VEHICLE FAILED TO START AGAIN SEVEN DAYS LATER. *JB

BLOWER MOTOR WAS RUNNING ON LOW. I DETECTED A FAINT ODOR OF SOMETHING HOT. BLOWER QUIT WORKING. RUNS ON HI SPEED (4) ONLY. WILL NOT RUN ON SPEEDS 1,2 OR 3. RESEARCHED PROBLEM ONLINE. SEEMS TO BE A COMMON PROBLEM. THERE IS AN ISSUE WITH THE BLOWER MOTOR RESISTOR AND CONNECTOR. WHEN I CHECKED, ONE OF THE PINS ON THE CONNECTOR AND SOCKET IS BURNED. POTENTIAL FOR FIRE EXISTS. I ORDERED NEW PARTS. (BLOWER MOTOR RESISTOR & CONNECTOR). *TR
